Closeorigin | 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. (Additional resources: RaycastHit). |
maxDistance | The max length of the cast. |
layerMask | A Layer mask that is used to selectively ignore colliders when casting a capsule. |
queryTriggerInteraction | Specifies whether this query should hit Triggers. |
bool True when the sphere sweep intersects any collider, otherwise false.
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. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast.
Additional resources: Physics.SphereCastAll, Physics.CapsuleCast, Physics.Raycast, Rigidbody.SweepTest.
