Time-based Collision Problems

endemoniada · 2003-11-18T09:01:23

Hi guys, I am using the classical time-based collision detection/response method like so: For every frame calculate each moving object''s next position, if a collision occured determine the first one that took place which will be a fraction of the total time of the frame, then move all the objects that fraction of the time frame. Now imagine a game similar to pool, let''s say a ball is moving very fast and is going through a narrow channel colliding with the walls as it travels; since it''s going fast a collision occurs at say 0.1 of every frame; since the frames are cut short the other moving objects become very slow and jerky while the fast ball is going through the channel. I was thinking of making the objects independant of one another but that opens up a can of worms. Any ideas ? Thanks.

How does limiting your frame rate fix any of your collision problems?

Create a function of "distance b/w two balls and parameter time" use MaximaMinima to calculate the time when two balls will have a minumum distance.

It is more easy to implement if the balls are not accelerating ie pool balls.

I am talking about Calculus
