Declaration

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

Parameters

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

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: For colliders that overlap the sphere 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.
