Type Function Library physics.* Return value The x and y of the reflected ray Revision Current Public Release (2017.3068) Keywords ray, raycast, casting, physics, collision, reflect, reflection See also physics.rayCast()
This function is used to reflect a vector as returned by physics.rayCast().
The reflected vector returned represents the direction of the reflection, and has a magnitude (length) of 1.
physics.reflectRay( fromX, fromY, hit )
Number. The starting x position of the ray.
Number. The starting y position of the ray.
