Class List
Here are the classes, structs, unions and interfaces with brief descriptions:
GalaxyWars.Scenes.Asteroid . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23
GalaxyWars.Scenes.Asteroids . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28
GalaxyWars.Graphics.BaseGame (Base game class for all the basic game support. Connects all
our helper classes together and makes our life easier! Note: This game was designed
for 16:9 (e.g. 1920x1200), but it also works just fine for 4:3 (1024x768, 800x600, etc.).
This is the reason you might see 1024x640 instead of 1024x768 in some width/height
calculations and the UI textures. The game looks best at 1920x1080 (HDTV 1080p
resolution) ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32
GalaxyWars.GameLogic.BasePlayer (Base player helper class, holds all the current game values: Game time, game over, level number, victory. More stuff that has impact to the
ShipController or ChaseCamera classes should be included here, else add them directly
to the Player class, which handles all the game logic. For example adding items or
powerups should be done in this class if they affect the speed or physics of our ship ) . 72
GalaxyWars.GameLogic.ChaseCamera (Chase camera for our car. We are always close behind it.
The camera rotation is not the same as the current car rotation, we interpolate the values
a bit, allowing the user to do small changes without rotating the camera frantically. Also
feels more realistic in curves. Derived from the CarController class, which controls the
car by the user input. This camera class is not controlled by the user, its all automatic! ) 77
GalaxyWars.Helpers.ColorHelper (Color helper, just to convert colors to different formats and
providing more helper methods missing in the Color class ) . . . . . . . . . . . . . . . 90
GalaxyWars.Helpers.Directories (Helper class which stores all used directories ) . . . . . . . . . 95
GalaxyWars.Helpers.FileHelper (File helper class to get text lines, number of text lines, etc.
Update: Now also supports the XNA Storage classes :) ) . . . . . . . . . . . . . . . . 97
GalaxyWars.Particles.FireParticleSystem (Custom particle system for creating a flame effect ) . 104
GalaxyWars.Graphics.Material (Material class for DirectX materials used for Models. Consists
of normal DirectX material settings (ambient, diffuse, specular), the diffuse texture and
optionally of normal map, height map and shader parameters ) . . . . . . . . . . . . . 106
GalaxyWars.Graphics.Model (Model class for loading and displaying x files including all materials and textures. Provides load and render functions to render static non animated
models (mostly 1 mesh), for animated models we need a more advanced class, which
is not required for this game yet ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 114

Class Index
GalaxyWars.Graphics.Texture (Texture class helping you with using DirectX Textures and handling possible errors that can happen while loading (stupid DirectX error messages
telling you absolutly nothing, so a lot of pre-checks help you determinate the error
before even calling DirectX methods) ) . . . . . . . . . . . . . . . . . . . . . . . . . . 124
GalaxyWars.GalaxyWarsManager (Manager class of the game. Handles all game screens, which
themself handle all the game logic ) . . . . . . . . . . . . . . . . . . . . . . . . . . . 136

the game ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 145
GalaxyWars.Properties.GameSettings (Game settings, stored in a custom XML file. The reason
for this is we want to be able to store our game data on the Xbox360 too. On the PC we
could just use a Settings/config file and have all the code autogenerated for us, but this
way it works both on PC and Xbox. Note: The default instance for the game settings is
in this class, this way we get the same behaviour as for normal Settings files! ) . . . . . 149

our game. Helps us to put them all into one list and manage them in our RaceGame ) . 162
GalaxyWars.GameLogic.Input (Input helper class, captures all the mouse, keyboard and XBox
360 controller input and provides some nice helper methods and properties. Will also
keep track of the last frame states for comparison if a button was just pressed this frame,
but not already in the last frame ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 163

GalaxyWars.Graphics.LineManager2D (LineManager class, used for drawing lines. We can’t
simply draw lines like in OpenGL (glLine) because we need to do everything with

GalaxyWars.Graphics.LineManager3D (Helper class for game for rendering lines. This class will
collect all line calls, then build a new vertex buffer if any line has changed or the line
number changed and finally will render all lines in the vertex buffer at the end of the
frame (so this class is obviously only for 2D lines directly on screen, no z buffer and no
stuff will be in front of the lines, because everything is rendered at the end of the frame) )202
GalaxyWars.Graphics.LineManager3D.Line (Struct for a line, instances of this class will be
added to lines ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 208

Health, Speed, Lifes and Score. Note: This class is just used in GalaxyWars and we
only have 1 instance of it for the current player for the current game. If we want to have
more than 1 player (e.g. in multiplayer mode) you should add a multiplayer class and
have all player instances there ) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 275

GalaxyWars.GameLogic.SpaceshipPhysics (Spaceship controller class for controlling the ship
we control. This class is derived from the BasePlayer class, which stores all important
game values for us (game time, game over, etc.). The ChaseCamera is then derived
from this class and finally we got the Player class itself at the top, which is deriven
from all these classes. This way we can easily access everything from the Player class ) 348

vertex buffers for on screen rendering used in PreScreen and PostScreen shaders. You
don’t have to create a VB for every shader anymore, just call VBScreenHelper.Render()
and everything will be created for you and reused if same parameters are requested
again! Supports also Grid screen rendering required for radial motion blur ) . . . . . . 418

5.2
Package GalaxyWars.GameLogic
Classes
• class BasePlayer
Base player helper class, holds all the current game values: Game time, game over, level number, victory.
More stuff that has impact to the ShipController or ChaseCamera classes should be included here, else add
them directly to the Player class, which handles all the game logic. For example adding items or powerups
should be done in this class if they affect the speed or physics of our ship.
• class ChaseCamera
Chase camera for our car. We are always close behind it. The camera rotation is not the same as the
current car rotation, we interpolate the values a bit, allowing the user to do small changes without rotating
the camera frantically. Also feels more realistic in curves. Derived from the CarController class, which
controls the car by the user input. This camera class is not controlled by the user, its all automatic!
• class Input
Input helper class, captures all the mouse, keyboard and XBox 360 controller input and provides some nice
helper methods and properties. Will also keep track of the last frame states for comparison if a button was
just pressed this frame, but not already in the last frame.
• class Player
Player helper class, holds all the current game properties: Fuel, Health, Speed, Lifes and Score. Note: This
class is just used in GalaxyWars and we only have 1 instance of it for the current player for the current
game. If we want to have more than 1 player (e.g. in multiplayer mode) you should add a multiplayer class
and have all player instances there.
• class ScreenshotCapturer
This is a game component that implements IUpdateable.
• class SpaceshipPhysics
Spaceship controller class for controlling the ship we control. This class is derived from the BasePlayer
class, which stores all important game values for us (game time, game over, etc.). The ChaseCamera is then
derived from this class and finally we got the Player class itself at the top, which is deriven from all these
classes. This way we can easily access everything from the Player class.
5.3 Package GalaxyWars.GameScreens
5.3
13
Package GalaxyWars.GameScreens
Classes
• class GameScreen
GameScreen, just manages the on screen display for the game.
• class Help
Help.
• interface IGameScreen
Game screen helper interface for all game screens of our game. Helps us to put them all into one list and
manage them in our RaceGame.
• class MainMenu
Main menu.
• class Options
Options.
• class SplashScreen
Splash screen.
14
5.4
Package GalaxyWars.Graphics
Classes
• class BaseGame
Base game class for all the basic game support. Connects all our helper classes together and makes our
life easier! Note: This game was designed for 16:9 (e.g. 1920x1200), but it also works just fine for
4:3 (1024x768, 800x600, etc.). This is the reason you might see 1024x640 instead of 1024x768 in some
width/height calculations and the UI textures. The game looks best at 1920x1080 (HDTV 1080p resolution).
• class LensFlare
Lens flare class for simple 2d lens flare rendering.
• class LineManager2D
LineManager class, used for drawing lines. We can’t simply draw lines like in OpenGL (glLine) because
we need to do everything with vertex buffers, which is a bit more work (and using DrawPrimitives directly
produces way worse code).
• class LineManager3D
Helper class for game for rendering lines. This class will collect all line calls, then build a new vertex buffer
if any line has changed or the line number changed and finally will render all lines in the vertex buffer at
the end of the frame (so this class is obviously only for 2D lines directly on screen, no z buffer and no stuff
will be in front of the lines, because everything is rendered at the end of the frame).
• class Material
Material class for DirectX materials used for Models. Consists of normal DirectX material settings (ambient, diffuse, specular), the diffuse texture and optionally of normal map, height map and shader parameters.
• class MeshRenderManager
Mesh render manager, a little helper class which allows us to render all our models with much faster
performance through sorting by material and shader techniques.
• class Model
Model class for loading and displaying x files including all materials and textures. Provides load and
render functions to render static non animated models (mostly 1 mesh), for animated models we need a
more advanced class, which is not required for this game yet.
• class PrimitivesRenderer
• struct TangentVertex
Tangent vertex format for shader vertex format used all over the place. It contains: Position, Normal vector,
texture coords, tangent vector.
• class Texture
Texture class helping you with using DirectX Textures and handling possible errors that can happen while
loading (stupid DirectX error messages telling you absolutly nothing, so a lot of pre-checks help you determinate the error before even calling DirectX methods).
• class TextureFont
Texture font for our game, uses GameFont.png. If you want to know more details about creating bitmap
fonts in XNA, how to generate the bitmaps and more details about using it, please check out the following links:
http://www.angelcode.com/products/bmfont/.
5.4 Package GalaxyWars.Graphics
15
• class TextureFontBigNumbers
TextureFontBigNumbers.
• class UIRenderer
Helper class to render all UI 2D stuff. Rendering textures is very easy with XNA using the Sprite class, but
we still have to create SpriteBatches. This class helps and handles everything for us.
16
5.5
Package GalaxyWars.Helpers
Classes
• class ColorHelper
Color helper, just to convert colors to different formats and providing more helper methods missing in the
Color class.
• class Directories
Helper class which stores all used directories.
• class FileHelper
File helper class to get text lines, number of text lines, etc. Update: Now also supports the XNA Storage
classes :).
• class Log
Log will create automatically a log file and write log/error/debug info for simple runtime error checking,
very useful for minor errors, such as finding not files. The application can still continue working, but this
log provides an easy support to find out what files are missing (in this example).
• class RandomHelper
Random helper.
• class Vector3Helper
Vector 3 helper.
5.6 Package GalaxyWars.Particles
5.6
17
Package GalaxyWars.Particles
Classes
• class FireParticleSystem
Custom particle system for creating a flame effect.
• class ParticleEmitter
Helper for objects that want to leave particles behind them as they move around the world. This emitter
implementation solves two related problems:.
• class ParticleSettings
Settings class describes all the tweakable options used to control the appearance of a particle system.
• class ParticleSystem
The main component in charge of displaying particles.
• struct ParticleVertex
Custom vertex structure for drawing point sprite particles.
18
5.7
Package GalaxyWars.Properties
Classes
• class GameSettings
Game settings, stored in a custom XML file. The reason for this is we want to be able to store our game data
on the Xbox360 too. On the PC we could just use a Settings/config file and have all the code autogenerated
for us, but this way it works both on PC and Xbox. Note: The default instance for the game settings is in
this class, this way we get the same behaviour as for normal Settings files!
5.8 Package GalaxyWars.Scenes

Package GalaxyWars.Scenes
Classes
• class Asteroid

5.9
Package GalaxyWars.Shaders
Classes
• class PostScreenGlow
Post screen glow shader based on PostScreenGlow.fx. Derive from PostScreenMenu, this way we can save
duplicating the effect parameters and use the same RenderToTextures.
• class PostScreenMenu
Post screen glow shader based on PostScreenMenu.fx.
• class PreScreenSkyCubeMapping
Pre screen sky cube mapping.
• class RenderToTexture
Render to texture helper class based on the Texture class. This class allows to render stuff onto textures, if
thats not supported, it will just not work and report an engine log message. This class is required for most
PostScreenShaders.
• class ShaderEffect
Shader effect class. You can either directly use this class by providing a fx filename in the constructor or
derive from this class for special shader functionality (see post screen shaders for a more complex example).
• class VBScreenHelper
The VBScreenHelper class helps you to create and use vertex buffers for on screen rendering used in PreScreen and PostScreen shaders. You don’t have to create a VB for every shader anymore, just call VBScreenHelper.Render() and everything will be created for you and reused if same parameters are requested
again! Supports also Grid screen rendering required for radial motion blur.

• static Rectangle CalcRectangle (int relX, int relY, int relWidth, int relHeight)
Calc rectangle, helper method to convert from our images (1024) to the current resolution. Everything will
stay in the 16/9 format of the textures.
• static Rectangle CalcRectangleWithBounce (int relX, int relY, int relWidth, int relHeight, float
bounceEffect)
Calc rectangle with bounce effect, same as CalcRectangle, but sizes the resulting rect up and down depending on the bounceEffect value.
• static Rectangle CalcRectangleKeep4To3 (int relX, int relY, int relWidth, int relHeight)
Calc rectangle, same method as CalcRectangle, but keep the 4 to 3 ratio for the image. The Rect will take
same screen space in 16:9 and 4:3 modes. E.g. Buttons should be displayed this way. Should be used for
1024px width graphics.
• static Rectangle CalcRectangleKeep4To3 (Rectangle gfxRect)
• static Rectangle CalcRectangle1600 (int relX, int relY, int relWidth, int relHeight)
Calc rectangle for 1600px width graphics.
• static Rectangle CalcRectangle2000 (int relX, int relY, int relWidth, int relHeight)

• static Rectangle CalcRectangleKeep4To3AlignBottom (int relX, int relY, int relWidth, int relHeight)
Calc rectangle keep 4 to 3 align bottom.
• static Rectangle CalcRectangleKeep4To3AlignBottomRight (int relX, int relY, int relWidth, int relHeight)
34
Class Documentation
Calc rectangle keep 4 to 3 align bottom right.
• static Rectangle CalcRectangleCenteredWithGivenHeight (int relX, int relY, int relHeight, Rectangle
gfxRect)
Calc rectangle centered with given height. This one uses relX and relY points as the center for our rect. The
relHeight is then calculated and we align everything with help of gfxRect (determinating the width). Very
useful for buttons, logos and other centered UI textures.
• static void SetAlphaBlendingEnabled (bool value)
Alpha blending.
• static void SetCurrentAlphaMode (AlphaMode value)
Current alpha mode.
• static Point Convert3DPointTo2D (Vector3 point)
Convert 3D vector to 2D vector, this is kinda the oposite of GetScreenPlaneVector (not shown here). This
can be useful for user input/output, because we will often need the actual position on screen of an object in
3D space from the users view to handle it the right way. Used for lens flare and asteroid optimizations.
• static bool PointInFront (Vector3 point)
Is point in front of camera?
• static bool PointVisible (Vector3 point, float checkOffset)
Helper to check if a 3d-point is visible on the screen. Will basically do the same as IsInFrontOfCamera and
Convert3DPointTo2D, but requires less code and is faster. Also returns just an bool. Will return true if point
is visble on screen, false otherwise. Use the offset parameter to include points into the screen that are only
a couple of pixel outside of it.

• static Matrix worldMatrix
Matrices for shaders. Used in a similar way than in Rocket Commander, but since we don’t have a fixed
function pipeline here we just use these values in the shader. Make sure to set all matrices before calling
a shader. Inside a shader you have to update the shader parameter too, just setting the WorldMatrix alone
does not work.

Class Documentation
• static Vector3 camPosition
Camera pos, updated each frame in ViewMatrix! Public to allow easy access from everywhere, will be
called a lot each frame, for example Model.Render uses this for distance checks.
• static Vector3 cameraRotation = new Vector3(0, 0, 1)
Camera rotation, used to compare objects for visibility.
• static Matrix invViewMatrix
Remember inverse view matrix.
• static bool isAppActive = true
• static RenderTarget2D remSceneRenderTarget = null
Remember scene render target. This is very important because for our post screen shaders we have to
render our whole scene to this render target. But in the process we will use many other shaders and they
might set their own render targets and then reset it, but we need to have this scene still to be set. Don’t reset
to the back buffer (with SetRenderTarget(0, null), this would stop rendering to our scene render target and
the post screen shader will not be able to process our screen. The whole reason for this is that we can’t use
StrechRectangle like in Rocket Commander because XNA does not provide that function (the reason for that
is cross platform compatibility with the XBox360). Instead we could use ResolveBackBuffer, but that method
is VERY SLOW. Our framerate would drop from 600 fps down to 20, not good. However, multisampling will
not work, so we will disable it anyway!
• static RenderTarget2D lastSetRenderTarget = null
Remember the last render target we set, this way we can check if the rendertarget was set before calling
resolve!
• static List< RenderToTexture > remRenderToTextures = new List<RenderToTexture>()
Remember render to texture instances to allow recreating them all when DeviceReset is called.

static Point GalaxyWars.Graphics.BaseGame.Convert3DPointTo2D (Vector3 point)
[static]
Convert 3D vector to 2D vector, this is kinda the oposite of GetScreenPlaneVector (not shown here). This
can be useful for user input/output, because we will often need the actual position on screen of an object in
3D space from the users view to handle it the right way. Used for lens flare and asteroid optimizations.
Parameters:
point 3D world position

Helper to check if a 3d-point is visible on the screen. Will basically do the same as IsInFrontOfCamera
and Convert3DPointTo2D, but requires less code and is faster. Also returns just an bool. Will return true
if point is visble on screen, false otherwise. Use the offset parameter to include points into the screen that
are only a couple of pixel outside of it.
Parameters:

RenderTarget2D GalaxyWars.Graphics.BaseGame.remSceneRenderTarget = null
[static, private]
Remember scene render target. This is very important because for our post screen shaders we have to
render our whole scene to this render target. But in the process we will use many other shaders and they
might set their own render targets and then reset it, but we need to have this scene still to be set. Don’t
reset to the back buffer (with SetRenderTarget(0, null), this would stop rendering to our scene render target
and the post screen shader will not be able to process our screen. The whole reason for this is that we can’t
use StrechRectangle like in Rocket Commander because XNA does not provide that function (the reason
for that is cross platform compatibility with the XBox360). Instead we could use ResolveBackBuffer, but
that method is VERY SLOW. Our framerate would drop from 600 fps down to 20, not good. However,
multisampling will not work, so we will disable it anyway!
6.3.5.42
RenderTarget2D GalaxyWars.Graphics.BaseGame.lastSetRenderTarget = null

Remember the last render target we set, this way we can check if the rendertarget was set before calling
resolve!

• static int MaxViewDistance [get, set]
Maximum view distance.
• IEnumerable< Vector3 > Positions [get]
Provides positions of all vertices in the vertex buffer.
Private Attributes
• string name = ""
Name of this model, also used to load it from the content system.
• XnaModel xnaModel = null
Underlying xna model object. Loaded with the content system.
• Matrix[ ] transforms = null
Transform matrices for this model, used in all Render methods, build once in the constructor, it never
changes and none of our models are animated.
• float realScaling = 1.0f
Scaling for this object, used for distance comparisons.
• float scaling = 1.0f
• bool hasAlpha = false
Does this model has alpha textures? Then render with alpha blending turned on. This is usually false and
rendering is faster without alpha blending. Also used to skip shadow receiving, which looks strange on
palms.
• bool isShip = false
Is this the ship model? Set in constructor and used in the render methods, this way we can compare much
faster when rendering!
• ModelMesh animatedMesh = null
If we want to animated some mesh in the model, just set the modelmesh here. Used for the windmill, which
is rotated in Render!
• List< EffectParameter > cachedEffectParameters = new List<EffectParameter>()
Cached effect parameters to improve performance. For around 100 000 objects we save 1 second per effect
parameters call. We only save the world matrix, worldViewProj matrix, viewInverse matrix and the lightDir
vector effect parameters. Update: We also save diffuseTexture, ambientColor and diffuseColor now.
• List< bool > cachedIsReflectionSpecularTechnique = new List<bool>()
Another helper to check if the effect technique is "ReflectionSpecular". Checking this each frame takes a lot
of time, this helper does the check only once in the constuctor. Used in RenderCar!
• Dictionary< ModelMeshPart, MeshRenderManager.RenderableMesh > renderableMeshes
Renderable meshes dictionary. Used to render every RenderableMesh in our render method.
116
Class Documentation
• static readonly Matrix objectMatrix
Default object matrix to fix models from 3ds max to our engine!
• static int maxViewDistance = 200
Default view distance optimizer is at 250m, then skip stuff. This will be reduced as our framerate runs low
to improve performance on low end systems.

bool GalaxyWars.Graphics.Model.hasAlpha = false [private]
Does this model has alpha textures? Then render with alpha blending turned on. This is usually false and
rendering is faster without alpha blending. Also used to skip shadow receiving, which looks strange on
palms.
6.11.4.8
bool GalaxyWars.Graphics.Model.isShip = false [private]
Is this the ship model? Set in constructor and used in the render methods, this way we can compare much
faster when rendering!
6.11.4.9

If we want to animated some mesh in the model, just set the modelmesh here. Used for the windmill, which
is rotated in Render!
6.11.4.10
List<EffectParameter> GalaxyWars.Graphics.Model.cachedEffectParameters = new
List<EffectParameter>() [private]
Cached effect parameters to improve performance. For around 100 000 objects we save 1 second per effect
parameters call. We only save the world matrix, worldViewProj matrix, viewInverse matrix and the lightDir
vector effect parameters. Update: We also save diffuseTexture, ambientColor and diffuseColor now.
6.11.4.11
List<bool> GalaxyWars.Graphics.Model.cachedIsReflectionSpecularTechnique = new
List<bool>() [private]
Another helper to check if the effect technique is "ReflectionSpecular". Checking this each frame takes a
lot of time, this helper does the check only once in the constuctor. Used in RenderCar!

GalaxyWars.Graphics.MeshRenderManager Class Reference
• RenderableMesh Add (VertexBuffer vertexBuffer, IndexBuffer indexBuffer, ModelMeshPart part,
Effect effect)
Add model mesh part with the used effect to our sortedMeshes list. Neither the model mesh part nor the
effect is directly used, we will extract all data from the model and only render the index and vertex buffers
later. The model mesh part must use the TangentVertex format.
• void Render ()
Render all meshes we collected this frame sorted by techniques and materials. This method is about 3-5
times faster than just using Model’s Mesh.Draw method (see commented out code there). The reason for
that is that we require only very few state changes and render everthing down as fast as we can. The only
optimization left would be to put vertices of several meshes together if they are static and use the same
technique and material. But since meshes have WriteOnly vertex and index buffers, we can’t do that without
using a custom model format.
Private Attributes
• List< MeshesPerMaterialPerTechniques > sortedMeshes
Sorted meshes we got. Everything is sorted by techniques and then sorted by materials. This all happens
at construction time. For rendering use renderMatrices list, which is directly in the most inner list of
sortedMeshes (the RenderableMesh objects).
• static VertexBuffer lastVertexBufferSet = null
Don’t set vertex and index buffers again if they are already set this frame.
• static IndexBuffer lastIndexBufferSet = null
Classes
• class MeshesPerMaterial
Meshes per material.
• class MeshesPerMaterialPerTechniques
Meshes per material per techniques.
• class RenderableMesh
Renderable mesh, created in the Model constructor and is rendered when we render all the models at once
at the end of each frame!
6.27 GalaxyWars.Graphics.MeshRenderManager Class Reference
6.27.1
223
We keep a list of lists of lists for rendering our RenderableMeshes sorted by techniques first and materials
second. The most outer list contains all techniques (see MeshesPerMaterialPerTechniques). Then the first
inner list contains all materials (see MeshesPerMaterial). And finally the most inner list contains all meshes
that use the technique and material we got. Additionally we could also sort by shaders, but since all models
use the same shader (normalMapping), that is the only thing we support here. Improving it to support more
shaders is easily possible.
All this is created in the Model constructor. At runtime we just go through these lists and render everything
down as quickly as possible.

Class Documentation
If an object wants to create particles very slowly, less than once per frame, it can be a pain to keep track of
which updates ought to create a new particle versus which should not.
If an object is moving quickly and is creating many particles per frame, it will look ugly if these particles
are all bunched up together. Much better if they can be spread out along a line between where the object
is now and where it was on the previous frame. This is particularly important for leaving trails behind fast
moving objects such as rockets.
This emitter class keeps track of a moving object, remembering its previous position so it can calculate the
velocity of the object. It works out the perfect locations for creating particles at any frequency you specify,
regardless of whether this is faster or slower than the game update rate.

Public Types
• enum SizeType
Posible size types for creating a RenderToTexture object.
• RenderToTexture (SizeType setSizeType)
Creates an offscreen texture with the specified size which can be used for render to texture.
• void HandleDeviceReset ()
Handle the DeviceReset event, we have to re-create all our render targets.
• void Clear (Color clearColor)
Clear render target (call SetRenderTarget first).
• bool SetRenderTarget ()
Set render target to this texture to render stuff on it.
• void Resolve ()
Resolve render target. For windows developers this method may seem strange, why not just use the rendertarget’s texture? Well, this is just for the Xbox360 support. The Xbox requires that you call Resolve first
before using the rendertarget texture. The reason for that is copying the data over from the EPRAM to the
video memory, for more details read the XNA docs. Note: This method will only work if the render target
was set before with SetRenderTarget, else an exception will be thrown to ensure correct calling order.
6.44 GalaxyWars.Shaders.RenderToTexture Class Reference
307
Properties
• DepthStencilBuffer ZBufferSurface [get]
ZBuffer surface.
• RenderTarget2D RenderTarget [get]
Render target.
• override XnaTexture XnaTexture [get]
Override how to get XnaTexture, we have to resolve the render target for supporting the Xbox, which requires
calling Resolve first! After that you can call this property to get the current texture.
• bool UsesHighPercisionFormat [get]
Does this texture use some high percision format? Better than 8 bit color?
• void CalcSize ()
Calc size.
• void Create ()
Create.
• static bool CheckRenderTargetFormat (SurfaceFormat format)
Check if we can use a specific surface format for render targets.
Private Attributes
• RenderTarget2D renderTarget = null
Our render target we are going to render to. Much easier than in MDX where you have to use Surfaces, etc.
Also supports the Xbox360 model of resolving the render target texture before we can use it, otherwise the
RenderToTexture class would not work on the Xbox360.
• DepthStencilBuffer zBufferSurface = null
Z buffer surface for shadow mapping render targets that do not fit in our resolution. Usually unused!
• SizeType sizeType
Size type.
• bool usesHighPercisionFormat = false
308
Class Documentation
• bool alreadyResolved = false
Make sure we don’t call XnaTexture before resolving for the first time!
• static int RenderToTextureGlobalInstanceId = 0
Id for each created RenderToTexture for the generated filename.

FullScreen Uses the full screen size for this texture.
HalfScreen Uses half the full screen size, e.g. 800x600 becomes 400x300.
QuarterScreen Uses a quarter of the full screen size, e.g. 800x600 becomes 200x150.
ShadowMap Shadow map texture, usually 1024x1024, but can also be better like 2048x2048 or
4096x4096.

void GalaxyWars.Shaders.RenderToTexture.Resolve ()
Resolve render target. For windows developers this method may seem strange, why not just use the rendertarget’s texture? Well, this is just for the Xbox360 support. The Xbox requires that you call Resolve first
before using the rendertarget texture. The reason for that is copying the data over from the EPRAM to the
video memory, for more details read the XNA docs. Note: This method will only work if the render target
was set before with SetRenderTarget, else an exception will be thrown to ensure correct calling order.

RenderTarget2D GalaxyWars.Shaders.RenderToTexture.renderTarget = null
[private]
Our render target we are going to render to. Much easier than in MDX where you have to use Surfaces, etc.
Also supports the Xbox360 model of resolving the render target texture before we can use it, otherwise the
RenderToTexture class would not work on the Xbox360.
6.44.5.2
DepthStencilBuffer GalaxyWars.Shaders.RenderToTexture.zBufferSurface = null

Z buffer surface for shadow mapping render targets that do not fit in our resolution. Usually unused!

6.44.6.3
override XnaTexture GalaxyWars.Shaders.RenderToTexture.XnaTexture [get]
Override how to get XnaTexture, we have to resolve the render target for supporting the Xbox, which
requires calling Resolve first! After that you can call this property to get the current texture.

Public Attributes
• const float SpaceshipMass = 1000
Default spaceship mass (1000 kg).
• const float DefaultMaxSpeed = 275.0f
Max speed of the spaceship.
• const float MaxPossibleSpeed = 290.0f
• const float DefaultMaxAccelerationPerSec = 2.5f
Max. acceleration in m/s∧ 2 we can do per second. We have also to define the max and min overall accelleration we can do with our spaceship.
• const float MaxAcceleration = 5.75f
• const float MinAcceleration = -3.25f
• const float MaxRotationPerSec = 1.3f
Max rotation per second we use for our ship.
• const float MinSensitivity = 0.5f
Minimum controller sensitivity.
• Vector3 GetPosition (List< Vertex > path, float t)
• const float SpaceshipHeight = 2.0f
This will be elevated above the ship position to let our camera look at the roof of it.
• static float maxSpeed = DefaultMaxSpeed ∗ 1.05f
Max speed of the ship. We start with the speed 0, then it is increased based on the current acceleration value
to this maxSpeed value.
• static float shipMass = SpaceshipMass ∗ 1.015f
Mass of the ship. Used for physics calculations.
• static float maxAccelerationPerSec = DefaultMaxAccelerationPerSec ∗ 0.85f
Current acceleration of the ship. Drive faster or break with up/down, left/right mouse or the gamepad
(left/right triggers or right thumb). The acceleration influcences the current speed of the ship.
350
Class Documentation
Properties
• Vector3 SpaceshipUpVector [get]
Ship up vector.
• Vector3 ShipPosition [get]
Ship position.
• float Speed [get]
Speed.
• float Acceleration [get]
Acceleration.
• Vector3 LookAtPos [get]
Look at position.
• Vector3 ShipDirection [get]
Ship direction.
• Vector3 ShipRight [get]
Ship right.
• List< Vertex > Path [get, set]
Path to be followed by the spaceship.
• float PathTime [get, set]
Time (between 0 and 1) to specify the position on the path.
• Matrix ShipRenderMatrix [get]
Ship render matrix, this is the final matrix for rendering our ship, which is called by Update each frame.
Private Attributes
• const float AirFrictionPerSpeed = 0.66f
Air friction we get if we’re flying fast, this slows us down very fast if we’re flying fast. This could be
extended to include wind and then even at low speeds the air friction would slow us down or even influcene
our movement.
• const float MaxAirFriction = AirFrictionPerSpeed ∗ 200.0f
Max air friction, this way we can have a good air friction for low speeds.
• const float BrakeSlowdown = 10.0f
Break slowdown per second, 1.0 means we need 1 second to do a full break. Slowdown is also limited by
max. 100 per sec! Note: This would not make sense in a real world simulation because stopping the car
needs usually more time and is highly dependant on the speed resultin in bigger stopping distances. For this
game it is easier and more fun to just brake always the same.
• const float MinViewDistance = 0.2f
351
The closest the camera should ever come to the ship.
• const float MaxViewDistance = 1.8f
The furthest the camera should ever be from the ship. (This is ignored during at the start of the race for
zooming in).
• Vector3 shipPosition
Ship position, updated each frame by our current speed vector.
• Vector3 shipDirection
Direction the ship is currently heading.
• Vector3 shipUp
Ship up vector for orientation.
• Vector3 shipForce
Force we currently apply on our ship. Usually we determinate how much acceleration we get through
the controls and multiplying that with the current direction vector. But for gravity, staying on the ground,
crashes, collisions impulses and all other forces this vector might be somewhat different. Used each frame
to change the speed.
• float shipSpeed
Speed of our ship, just in the direction of our ship. Sliding is a nice feature, but it overcomplicates too much
and for this game sliding would be really bad and make it much harder to drive!
• float viewDistance = 1.0f
View distance, which we can change with page up/down and the mouse wheel, but it always moves back to
1. The real view distance is also changed depending on how fast we’re flying.
• float rotateShipAfterCollision = 0
Rotate ship after collision.
• List< Vertex > followPath = null
Path to be followed by the ship.
• float t = 0
Time parameter to get the position on the path (between 0 and 1).
• Matrix shipRenderMatrix = Matrix.Identity
Ship render matrix we calculate each frame.
• float lastAccelerationResult = 0.0f
• float virtualRotationAmount = 0.0f
• float verticalRotationAmount = 0.0f
• float rotationChange = 0.0f
• float verticalRotationChange = 0.0f

Apply friction. Basically we have 2 frictions that slow us down:
The friction from the contact of the wheels with the road (rolling
friction) and the air friction, which becomes bigger as we drive
faster. We need more force to overcome the resistances if we drive
faster. Our engine is strong enough to overcome the initial
car friction and air friction, but we want simulate that we need
more force to overcome the resistances at high speeds.
Usually this would require a more complex formula and the car
should need more fuel and force at high speeds, we just simulate that
by reducing the force depending on the frictions to get the same
effect while having our constant forces that are calculated above.

const float GalaxyWars.GameLogic.SpaceshipPhysics.SpaceshipMass = 1000
Default spaceship mass (1000 kg).
6.48.4.2
const float GalaxyWars.GameLogic.SpaceshipPhysics.DefaultMaxSpeed = 275.0f
Max speed of the spaceship.
6.48.4.3
const float GalaxyWars.GameLogic.SpaceshipPhysics.MaxPossibleSpeed = 290.0f
6.48.4.4
const float GalaxyWars.GameLogic.SpaceshipPhysics.DefaultMaxAccelerationPerSec =
2.5f
Max. acceleration in m/s∧ 2 we can do per second. We have also to define the max and min overall
accelleration we can do with our spaceship.
6.48.4.5
const float GalaxyWars.GameLogic.SpaceshipPhysics.MaxAcceleration = 5.75f
6.48.4.6

6.48.4.7
361
const float GalaxyWars.GameLogic.SpaceshipPhysics.AirFrictionPerSpeed = 0.66f
[private]
Air friction we get if we’re flying fast, this slows us down very fast if we’re flying fast. This could be
extended to include wind and then even at low speeds the air friction would slow us down or even influcene
our movement.
6.48.4.8
const float GalaxyWars.GameLogic.SpaceshipPhysics.MaxAirFriction =
AirFrictionPerSpeed ∗ 200.0f [private]
Max air friction, this way we can have a good air friction for low speeds.
6.48.4.9
const float GalaxyWars.GameLogic.SpaceshipPhysics.BrakeSlowdown = 10.0f
[private]
Break slowdown per second, 1.0 means we need 1 second to do a full break. Slowdown is also limited by
max. 100 per sec! Note: This would not make sense in a real world simulation because stopping the car
needs usually more time and is highly dependant on the speed resultin in bigger stopping distances. For
this game it is easier and more fun to just brake always the same.
6.48.4.10
const float GalaxyWars.GameLogic.SpaceshipPhysics.MaxRotationPerSec = 1.3f
Max rotation per second we use for our ship.
6.48.4.11

Minimum controller sensitivity.
6.48.4.12
const float GalaxyWars.GameLogic.SpaceshipPhysics.SpaceshipHeight = 2.0f

362
6.48.4.14
Class Documentation
const float GalaxyWars.GameLogic.SpaceshipPhysics.MaxViewDistance = 1.8f
[private]
The furthest the camera should ever be from the ship. (This is ignored during at the start of the race for
zooming in).
6.48.4.15
float GalaxyWars.GameLogic.SpaceshipPhysics.maxSpeed = DefaultMaxSpeed ∗ 1.05f
[static, protected]
Max speed of the ship. We start with the speed 0, then it is increased based on the current acceleration
value to this maxSpeed value.
6.48.4.16
float GalaxyWars.GameLogic.SpaceshipPhysics.shipMass = SpaceshipMass ∗ 1.015f
[static, protected]
Mass of the ship. Used for physics calculations.
6.48.4.17
float GalaxyWars.GameLogic.SpaceshipPhysics.maxAccelerationPerSec =
DefaultMaxAccelerationPerSec ∗ 0.85f [static, protected]
Current acceleration of the ship. Drive faster or break with up/down, left/right mouse or the gamepad
(left/right triggers or right thumb). The acceleration influcences the current speed of the ship.
6.48.4.18
Vector3 GalaxyWars.GameLogic.SpaceshipPhysics.shipPosition [private]
Ship position, updated each frame by our current speed vector.
6.48.4.19
Vector3 GalaxyWars.GameLogic.SpaceshipPhysics.shipDirection [private]
Direction the ship is currently heading.

Vector3 GalaxyWars.GameLogic.SpaceshipPhysics.shipUp [private]
Ship up vector for orientation.
6.48.4.21
Vector3 GalaxyWars.GameLogic.SpaceshipPhysics.shipForce [private]
Force we currently apply on our ship. Usually we determinate how much acceleration we get through
the controls and multiplying that with the current direction vector. But for gravity, staying on the ground,
363
crashes, collisions impulses and all other forces this vector might be somewhat different. Used each frame
to change the speed.
6.48.4.22
float GalaxyWars.GameLogic.SpaceshipPhysics.shipSpeed [private]
Speed of our ship, just in the direction of our ship. Sliding is a nice feature, but it overcomplicates too
much and for this game sliding would be really bad and make it much harder to drive!
6.48.4.23
float GalaxyWars.GameLogic.SpaceshipPhysics.viewDistance = 1.0f [private]
View distance, which we can change with page up/down and the mouse wheel, but it always moves back
to 1. The real view distance is also changed depending on how fast we’re flying.
6.48.4.24
float GalaxyWars.GameLogic.SpaceshipPhysics.rotateShipAfterCollision = 0
[private]
Rotate ship after collision.

Render all UI elements at the end of the frame, will also render the mouse cursor if we got a mouse attached.
Render all ui elements that we collected this frame. Flush user interface graphics, this are mainly all Texture.RenderOnScreen calls we made this frame so far. Used in UIRenderer.RenderTextsAndMouseCursor,
but can also be called to force rendering UI at a specific point in the code.

GalaxyWars.Shaders.VBScreenHelper Class Reference
The VBScreenHelper class helps you to create and use vertex buffers for on screen rendering used in
PreScreen and PostScreen shaders. You don’t have to create a VB for every shader anymore, just call VBScreenHelper.Render() and everything will be created for you and reused if same parameters are requested

GalaxyWars.Shaders.VBScreenHelper
GalaxyWars.Shaders.VBScreenHelper.VBScreen
• static void Render ()
Just render a vertex buffer with the screen coordinates. No subTexelSize stuff is performed, do that in the fx
file.
• static void Render10x10Grid ()
Just render a 10x10 grid with help of GridScreen on the screen. No subTexelSize stuff is performed, do that
in the fx file.
• static VBScreen vbScreenInstance = null
Vb screen instance.
• static GridScreen gridScreen10x10Instance = null
Grid screen 1 0x 10 instance.
Classes
• class GridScreen
Another vertex and index buffer for a screen grid, basically used for the same purpose as VBScreen, but
allows us to create a grid (e.g. 10x10), very useful for advanced post screen shaders.
• class VBScreen
VBScreen holds all data for the vbScreens list to reuse existing VBScreens. Handles also the VB, creation
and rendering.

class, which stores all important game values for us (game time, game over, etc.). The ChaseCamera is then
derived from this class and finally we got the Player class itself at the top, which is deriven from all these
classes. This way we can easily access everything from the Player class.
