      • Back when XNA was first announced at GDC 2004 it was said that XNA would be a unifying environment for both original Xbox(and future versions), PC and mobile devices. With the XNA framework now available for the Xbox 360 are there any plans for supporting the original Xbox I know there are about to be 10 million Xbox 360 consoles shipped by the end of this year, but as of last May Microsoft sai

      • Hi, i am reading of a Texture2D the given colors to extract my height data of a heightmap image. Therefor i use this code: Int32[] data = new Int32[heightMap.Width * heightMap.Height]; heightMap.GetData<Int32>(data); heightMap is a Texture2D object with a width and height of 500, so the data-array gets at runtime a size of 250.000. Fine but it fails on getting the data from the Texture2D

      • I need to do a 2d parallax floor sprite. (I want to closely emulate the style of an older game). Let me explain. I have a long, short rectangular floor texture. I'm rendering it as a texture on a 2 triangle (to make a square or rectangle) set of primitives, that is normally the same size as the texture, and the upper left corner is mapped to 0,0 of the texture, and the lower right corner to 1,1, e

      • Hi all, I'm about 90% finished with my XNA Starfield screensaver, and I'm wondering what the best solution is for storing my textures and whatnot. I think it'll be very clunky to add any content files to the System32 folder along with the .scr, so I've been trying to come up with a good spot for them. Wouldn't it be best to embed the files within the .exe and just load them from there I'm trying t

      • Hi all, I assume I am doing something wrong with the importing of content, but I can't seem to figure this out. I have 3 .bmp images that are each around 30kb. I am importing them as Textures and using the Sprite processor. The resultant .xnb files are 250-300 kb =/ I am fairly sure the .xnb file doesn't have mipmap data in it. Any idea why these images are becoming so large Thanks

      • I was wondering if i would be possible to display point sprites (in 3D) using the BasicEffect When I specify the position and the texture, I see colored points where the sprites should be (really the size of pixels). I guess the BasicEffect doesn't support point sprites, but because I cannot find the PointScaleA-C renderstates in XNA, I still have some hope. I found the PointSpriteEnable rendersta

      • I've been trying to adapt the C++ DirectX motion blur sample to XNA. This sample works perfectly on my NVidia 7900GT. In my own program I successfully create a "velocity" render target with SurfaceFormat.HalfVector2. Unfortunately something goes wrong with the graphics system when I set this with SetRenderTarget() - the program doesn't hang, it just refuses to render anything after that.

      • Hi Well, my latest game is really starting to come together. However, I've noticed something that I think is the cause of a memory leak. ParentGame.SoundBank.PlayCue( "spark_1" ); I've notice a positive allocation of memory whenever the "PlayCue" method on a SoundBank is called. This particular line of code is fired very regularly (its an electric arc sound) in my g

In the model loading example there is a line which reads: float aspectRatio = graphics.GraphicsDevice.Viewport.Width / graphics.GraphicsDevice.Viewport.Height; It took me quite some time as a beginner coder to figure out why my models were stretched over the x axis.

      • My problem is: I just want to draw some objects to a render target, and than save it to texture -> post process it. It works, if I turn off multisample. But if it's turned on, it behave like DepthBuffer would be turned off (the last drawed object will be the nearest, even if it's far away), but it's not. Again, if I only turn off the multisample, it works fine, if I turn it on, it's get crazy.

I wrote some simple code to check the keyboard state, and close the app if I hit escape, but that doesn't even work. I just assumed that this would all be handled for me, out of the box...
