Physics.CapsuleCastAll
static function CapsuleCastAll(point1: Vector3, point2: Vector3, radius: float, direction: Vector3, distance: float = Mathf.Infinity, layermask: int = DefaultRaycastLayers): RaycastHit[];
static RaycastHit[] CapsuleCastAll(Vector3 point1, Vector3 point2, float radius, Vector3 direction, float distance = Mathf.Infinity, int layermask = DefaultRaycastLayers);
static def CapsuleCastAll(point1 as Vector3, point2 as Vector3, radius as float, direction as Vector3, distance as float = Mathf.Infinity, layermask as int = DefaultRaycastLayers) as RaycastHit[]
Parameters

point1 The start of the capsule.
point2 The end of the capsule.
radius The radius of the capsule.
direction The direction into which to sweep the capsule.
distance The length of the sweep.
layerMask A Layer mask that is used to selectively ignore colliders when casting a capsule.
Returns
RaycastHit[] An array of all colliders hit in the sweep.
Description

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: The capsule 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 capsule cast will hit the collider at it's new position.
