      • Hello, I'm writing my own content importer for my maps. At the moment, I'm able to load all triangles and draw the map but i have a problem with textures. In my importer i load texture like this (it's just a test) : BasicMaterialContent material = new BasicMaterialContent(); String texturePath = Path.GetDirectoryName(filename) + "\\Textures\\wall.jpg"; if (!System.IO.File.Ex

      • OK, I have been having a lot of problems with this, and I have tried every possible solution and it does not seem to want to work. I am programming a Tile Engine that will run my RPG, and so far it has been going great. I have error logging, a TileManager for loading tiles into lists so that they are recallable at any time, and I have various other features that are currently being worked on.

      • Here i would like to ask about the texture coordinate for the cube mapping. I know that cube mapping did not use the normal coordinate that we use for normal texture coordinate. But i'm getting problem in understanding how the cube texture coordinate works. Let me put example here. Below is the vertex and fvf declaration: struct CUSTOMVERTEX {FLOAT X, Y, Z, RHW; DWORD COLOR; FLOAT V, W, U;}; #de

      • I want to make a component with the same functionality as a SpriteBatch, but it automatically translates, scales, and clips everything drawn with it. I figured I could inherit from SpriteBatch and override the Draw methods, but they're not overridable. I'd be forced to shadow the Draw calls and it kind of blows my whole object-oriented, polymorphic system outta the water. Right now I'm using co

      • Hey guys. I've the last couple of hours tried to implement an infinite projection matrix without succes. So I took a step back to see if I could even make some sense of the "normal" perspective projection matrix used by XNA. Normally I used the CreatePerspectiveFieldOfView() method to create the matrix. Here is what I've tried so far. What is XNA left-handed or right This code works but the vie

I need a way to determine which part of the tile can be walked on and which part can't. I can't do it based on pixel color, so I wanted to know if anyone could help me out with some bright ideas. I remember hearing something about an alpha channel mask you can put over you

      • This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the c

      • Visual Studio 2003 and 2005 default to tabs for spacing, yet for some reason XNA (and perhaps Visual C# Express) defaults to 4 spaces. Further, to find the setting to fix this is a little confusing - you need to realize the "Show All" checkbox is lurking at the bottom of the Options, check that, and then restart your hunt for the "Tabs" section. Please set the default to Tabs i

For these tests, I am using both positive and negative values for both the scale and rotation factors. With rotation, a positive value rotates the sprite clockwise and a negative value rotates the sprite counterclockwise. That's fine. I then
