/*
This function reflects an animated circle on a static circle.
It should first make sure that the animated circle is intersecting with the static one
- Parameters
- Center0s: The starting position of the animated circle's center
- Center0e: The ending position of the animated circle's center
- Radius0: The animated circle's radius
- Center1: The static circle's center
- Radius1: The static circle's radius
- Pi: This will be used to store the intersection point's coordinates (In case there's an intersection)
- R: Reflected vector R
- Returned value: Intersection time t
- -1.0f: If there's no intersection
- Intersection time: If there's an intersection
