      • Hello good people, I'm doing my own definition of IDrawable and IUpdatable mainly because none of them has setters in their properties. While doing an implementation of the IDrawable interface I thought that it was weird that it did not have any position property. Usually when drawing something you'd like to know where to draw it. My first thought was that the difference between the coordinate set

      • Hi, the DXGI_FORMAT_R11G11B10_FLOAT render target format seems to be a clear winner when it comes to HDR rendering. The question I could not find an answer in the documentation for is: is it guaranteed to support alpha blending, multi-sampling and filtering Thanks in advance, - Wolf

      • OK, after hours or working I got pixel perfect to work. I can have any shape, any site sprites and they will collide if two pixels match up. Now, my next part is response. If I have say two blocks collide moving on the same x-axis then they actully collide on multiple spots(the whole y-axis) to to bound properly I need to bounce off the normal(average) of all the of y positions.

      • Hi. Would it be possible to transform colors with Pixel Shader 2.0 similar to GDI+ with C# This is to say that if I have 2 images -- day and night image, which I blend from one image to another, which I can do that with GDI+'s ColorMatrix class. But as resolution gets bigger, so will the GDI+ that will have to redraw at a slower rate, such as a resolution of 1920x1080. Direct3D (and the deprica

I see that the XNA team has put large amounts of effort into some asset management in XNA, that includes the XACT audio cues for like "make it possible to change the sound triggered by some event without doing it in the programming".

When I do it for fun, I make small little text based games, and when I do it for classes- the "businessy" applications that we all have to make. I've given actual game dev a shot by using premade engines, 2D game dev with OpenGL and DirectX, and straightup giving a go at just making an engine. BUT, everytime

      • I'm not new to programming, but I'm new to game programming and C#. I'm wondering to what extent it's realistic for someone to make their own 3D (or for that matter 2D) game engine. The two projects I have in mind for myself are a turn-based 2D war/strategy game, and a 3D adventure game in the manner of "Dreamfall". On the 2D side, I feel confident I could come up with a 2D interface on my own.

What it does is that in debug mode it draws an ellipse (in fullscreen) and if I run it as an executible it draws a circle.

Third: I'd like to understand how the connect feedback system works. I
