public bool SweepTest (Vector3 direction, out RaycastHit hitInfo, float maxDistance= Mathf.Infinity, QueryTriggerInteraction queryTriggerInteraction= QueryTriggerInteraction.UseGlobal);

파라미터

direction The direction into which to sweep the rigidbody.
hitInfo If true is returned, hitInfo will contain more information about where the collider was hit (See Also: RaycastHit).
maxDistance The length of the sweep.
queryTriggerInteraction Specifies whether this query should hit Triggers.

반환

bool True when the rigidbody sweep intersects any collider, otherwise false.

설명

Tests if a rigidbody would collide with anything, if it was moved through the Scene.

Tests if a rigidbody would collide with anything, if it was moved through the Scene. This is similar to doing a Physics.Raycast for all points contained in any of a Rigidbody's colliders and returning the closest of all hits (if any) reported. This is useful for AI code, say if you need to know that an object would fit through a gap without colliding with anything.

Note that this function only works when a primitive collider type (sphere, cube or capsule) or a convex mesh is attached to the rigidbody object - concave mesh colliders will not work, although they can be detected in the Scene by the sweep.
