      • Hi all, I've set myself the task of recreating a number of the example Dx9 effects in Rendermonkey as an exercise. Worked through a few of the simpler ones successfully, and gaining a good understanding of HLSL in the process. Now, I think, I'll try the nifty refraction water effect, which is one of the examples under "reflection, refraction and water". It's the one with the skull

      • Well, I've hit a wall with my game's development, and since there was no GUI with XNA 1.0, I've decided to go ahead and make my own GUI system. I implemented a lot of mechanics for my game, but I need greater interaction to proceed development in a sane manner. So far I've just implemented the text drawing stuff from scratch. It uses only monospace fonts generated with BMFontGenerator without u

      • Hello Everyone, This is a fairly generic question, and I promise it may sound like a hardward question at first, but it's not really. Does anyone else notice how slow some of the DX10 samples in the Feb SDK are Specifically those that employ the geometry shader such as the displacement mapped lizard and the example of how to do cube mapping in one pass (when you check "Render Car")

      • Hi there - this is probably a very simple problem but I've not stumbled over the answer yet. My Art Monkey has just sent me a model with an animated gif file attached. XNA complains about this texture so presumably gifs are not yet supported. Is there a way round this For instance a simple way to apply a texture to a model, or change the UV coordinates a model is using, so I could have a big bi

      • Hi, I am currently porting my managed DX9 engine to XNA, and need to duplicated a model for writing vertex data to. In the old engine I just load the model twice to get 2 identical meshes, each with their own separate vertex buffer. With the content manager in XNA this appears to be 'optimized' into not working, as it appears to return the same vertex buffers for each model. This of course mea

      • I was a bit suprised to hear that XNA only worked on Visual Studio Express, but apparently that was just the XNA Game Studio Express which basically gives you all you need for Windows and XBox 360 development. But say if you just want to make a PC game, you can go ahead and install the XNA Framework, add it to your WinForm project, and it will run fine from there. For instance, I just created a em

I'm using bounding boxes with no Z specified. I thought it'd be easy like: -Velocity * (Size / 2 / Distance between 2 collided objects) But that fails horribly on objects of non-square size (64x32 for example) or on objects
