public static RaycastHit[] CapsuleCastAll(Vector3 point1, Vector3 point2, float radius, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);


point1 The center of the sphere at the start of the capsule.
point2 The center of the sphere at the end of the capsule.
radius The radius of the capsule.
direction The direction into which to sweep the capsule.
maxDistance The max length of the sweep.
layermask A Layer mask that is used to selectively ignore colliders when casting a capsule.
queryTriggerInteraction Specifies whether this query should hit Triggers.


RaycastHit[] An array of all colliders hit in the sweep.


Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.

Casts a capsule against all colliders in the Scene and returns detailed information on each collider which was hit. The capsule is defined by the two spheres with radius around point1 and point2, which form the two ends of the capsule. Hits are returned all colliders which would collide against this capsule if the capsule was moved along direction. 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.

Notes: For colliders that overlap the capsule at the start of the sweep, RaycastHit.normal is set opposite to the direction of the sweep, RaycastHit.distance is set to zero, and the zero vector gets returned in RaycastHit.point. You might want to check whether this is the case in your particular query and perform additional queries to refine the result. Passing a zero radius results in undefined output and doesn't always behave the same as Physics.Raycast.
