pong game needed + source
Author
hey, im gonna try to make a pong game but i need to see some sourc code on collision detection and ball speed and if the ball is out of the room the other player gets a point etc. So anyone knows a good pong + source? thnx
i just threw up my pong clone with source code on the GD showcase
written with C++ and DirectX 9.0

The collision detection is fairly simple for a pong game. There are three different things you need to test for:
1) A collision with the paddle. Fairly easy if you do simple bounding boxes. Should look fine.
2) Collision with the top/bottom walls. Just test the y coordinates of the ball. If it is colliding, then just set the direction of the ball to 90 degrees off what it was.
3) Collision with the right/left walls. Just test the x coordinates. If it is a hit, add a point to the other player and reset the ball.
First set it up so the ball will bounce off the top/bottom wals. Then add the paddle collision code. Then add the code for winning/losing. Just take it slowly and do everything one at a time.

oh i forgot to say i only want it pure win32 no directx or so.
Well the collison detection is the same no matter how you render it. The only difference is how you will be drawing the various objects (paddles and ball).
Not necesarily, in directx you can use the convenient helper funtions in D3DX like D3DXSphereBoundProbe(), that make it really easy to do collision on primitives.
Try this:

You'll first need to choose a language and an API to work with. SDL or Allegro are great choices for beginners to graphics programming, while OpenGL and DirectX are good choices if you plan to do things a little more complex. As for the language, C++ is the standard language in the industry. But I personally would recommend going with either Python (via PyGame, a Python SDL interpretation) or C# (via SDL.NET).
My pong compilation, rPong, was done using C++ and SDL. If I were to do it again, I would use C# and SDL.NET or Managed DirectX.
