Time when 2 objects will touch
Hi, I have 2 balls which rolls in different directions (something like billiard). I need to predict if the balls will touch and if they will I need to know when (in seconds). I know: - initial position of each ball VECTOR3 - velocity of each ball VECTOR3 - radius of each ball FLOAT
Any ideas? :) Thanks
You may try this to find intersection of two lines.

This is in Vector2 by the way, Vector3 will be much complicated. THen you can find time by t = x / v
Hope this helps.
I was trying this before, but its not what I need. Because even if their ways will cross, one ball can be slower and they will not touch. Or they can go both in one line and if the second one will be faster, they will touch.
