Описание

Casts a sphere along a ray and returns detailed information on what was hit.

This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way. Think of the sphere cast like a thick raycast. In this case the ray is specified by a start vector and a direction.

Notes: SphereCast will not detect colliders for which the sphere overlaps the collider.
If you move colliders from scripting or by animation, there needs to be at least one FixedUpdate executed so that the physics library can update it's data structures, before a SphereCast will hit the collider at it's new position.
