void b2TimeOfImpact | ( | b2TOIOutput * | output, |
const b2TOIInput * | input | ||
) |
Compute the upper bound on time before two shapes penetrate.
Time is represented as a fraction between [0,tMax]. This uses a swept separating axis and may miss some intermediate, non-tunneling collision. If you change the time interval, you should call this function again. Note: use b2Distance to compute the contact point and normal at the time of impact.
