| origin | The center of the sphere at the start of the sweep. |
| radius | The radius of the sphere. |
| direction | The direction into which to sweep the sphere. |
| hitInfo | If true is returned, hitInfo will contain more information about where the collider was hit (See Also: RaycastHit). |
| distance | The length of the sweep. |
| layerMask | A Layer mask that is used to selectively ignore colliders when casting a capsule. |
bool True when the capsule sweep intersects any collider, otherwise false.
Casts a sphere against all colliders in the scene 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.
Note: The sphere cast does not work against colliders configured as triggers. 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.See Also: Physics.SphereCastAll, Physics.CapsuleCast, Physics.Raycast, Rigidbody.SweepTest. function Update () {
