      • Okay, so I've already read through a couple of the threads here on the same issue, but nothing helps my situation! I'm trying to capture the texture data so I can do some collision detection on it. Texture2D entityA = resourceManager.getTexture(a.CurrentAnimation); uint[] bitsA = new uint[a.currentWidth*a.currentHeight]; entityA.GetData<uint>(0, a.CurrentFrame, bitsA, 0, bitsA.Length); a is

I use the base Windows Game project for test, and in the Initialize function I set some parameters: _graphics.GraphicsDevice.PresentationParameters.FullScreenRefreshRateInHz = 70; _graphics.SynchronizeWithVerticalRetrace =

I don't have the time to make an entire game by myself (I'm working full time and go to school part time), so I'd love to either join up with an existing team or build a brand new one.

Because they are structs they don't derive from a base class other than ValueType. If I use ValueType as the parameter I don't have access to the propertys of the vertex. Is this a case where refelection would be usefull C
