Ok and if i need to test / debug player sphere radius i just change the radius value for PointInSphere and thats same as changing player sphere radius? Im correct?

It tests for the sphere with specified radius. If i supply him radius 2, which is for ex. radius of the player sphere and this function will check that radius as if it was real sphere with that radius. I know im confuse things up but this is the way i understand it.

Anyways, thank you for the help. I will try.
But what about sliding / non sliding collision? I would like sliding more than sticking in wall.
