I'm in the process of developing a snooker game and I'm having trouble with the movement of the snooker balls. I've no problem tracking where there supposed to be going and when a collision occurs but I can't seem to figure out how to control the speed at which the balls move.
For example i've got the start and finish vectors of the white ball but at the moment all that i'm doing is a simple translation from start vector to finish vector. How do I simulate a powerfull shot and a soft shot?
Appreciate it if anyone can help me out.
