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

Parámetros

directionLa dirección en la cual barrer el rigidbody.
hitInfoSi true se devuelve, hitInfo contendrá más información acerca de dónde el collider ha golpeado (See Also: RaycastHit).
maxDistanceLa longitud del barrido.
queryTriggerInteractionEspecifica si esta consulta debería golpear Triggers.

Valor de retorno

bool True cuando el barrido del rigidbody intersecta cualquier collider, de lo contrario false.

Descripción

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.
