Hello Professor Fu-Kwun Hwang

I m currently developing a game JOGL(java opengl) in which multiple balls are present on the board n a striker is present using which we have to pot those other coins (Circular Disks) we have uptill now created the board n discs but we are stuck at collision detection part coz there are multiple discs involved

i have thought of creating an event which would detect collisions can u help us with how to go about it with multiple disks involved

thanking you in advance
