Mixing 2D and 3D

I forgot to show you last week that the Spritebatch draw code need to be modified slightly in order top mix 2D and 3D You need to use SaveStateMode.SaveSate if you don't explicitly order everything in your Draw code. Saving states can be SLOOWWWWW and significantly reduce your performance. More info on RenderStates

spriteBatch.Begin(SpriteBlendMode.AlphaBlend, SpriteSortMode.Deferred, SaveStateMode.SaveState);


The XNA basic effect is a simple implementation of a HLSL effect.

HLSL is Microsoft's High level implementation of FFE Fixed Function Pipeline implemented in video hardware. GPU Hardware does two things. The vertex shader runs first and is rasterized to 2D, then the pixel shaders run.

Final version of your game. Upload a final revision of your game that includes any modifications made since testing at midterm. The last requirement for the game is that if have some type of credits. The credits could be in the win condition if your game has one or on the lose/pause screen if there is no win condition.
