• jo123 Anything similar to D3DXCOLOR?

  D3DXCOLOR is a very handy class but I find it missing in managed DX. Yes, I used ColorValue, but I always type "*" or "+" for the operation and then have to change them to very long method calls. Why the managed DX should go without them The same operations are used more frequently in shaders. Operators can express better than a function call if properly used; that's why C# provides it. "+" is absolutely better ...Show All

  Hi, I have a question. Is there any plans to implement DirectMusic for Managed DirectX If so, I would like to know when. I'm a fan of DirectMusic and interactive music is important for games.

  Greetings! There have been a few posts/replies that touch on this subject, but I wanted to provide a thread that captured as much of this knowledge and ideas as possible.

• Radha Krishna Prasad How to change one class to another or how to include derived in base

  Hello guys, I've been making a 3D space game in DX9 and I've run to the following problem. I have base class TELESO for every object in the space and derive needed classes from it(asteroids, ships,etc)... Well, maybe you will find this solution bad, but ...its the only thing I could do...: I want to spread chunks from object when it is destroyed. However I cannot divide object into smaller parts ingame, though I can make them in 3D prog ...Show All
