High,

if you are just searching for collision detection and no response to this detection you might want to take a look at the fastgeo-unit from Arash Partow.

You can find his post in "My Projects" category in this forum.

The unit provides many many algorithms and calculations for primitive objects (2D and 3D), including collision algorithms like point in sphere, quad in triangle etc.

I use it for my dog fight contest entry and it seems to work very well.


If you can find something interesting about seperating objects (circles, rectangles (also rotated), etc. in 2D, you would help me very much.

Greetings,
Dirk
