Physics.SphereCastAll
static function SphereCastAll(origin: Vector3, radius: float, direction: Vector3, distance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers): RaycastHit[];
static RaycastHit[] SphereCastAll(Vector3 origin, float radius, Vector3 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers);
static def SphereCastAll(origin as Vector3, radius as float, direction as Vector3, distance as float = Mathf.Infinity, layerMask as int = DefaultRaycastLayers) as RaycastHit[]
Parameters

origin 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.
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.SphereCast, but this function will return all hits the sphere sweep intersects.

Casts a sphere against all colliders in the scene and returns detailed information on each collider which 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.

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