public static function SphereCastNonAlloc(origin: Vector3, radius: float, direction: Vector3, results: RaycastHit[], maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): int;
public static int SphereCastNonAlloc(Vector3 origin, float radius, Vector3 direction, RaycastHit[] results, 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.
results The buffer to save the hits into.
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

int The amount of hits stored into the results buffer.

Description

Cast sphere along the direction and store the results into buffer.

This is variant of Physics.SphereCastAll, but instead of allocating the array with the results of the query, it stores the results into the user-provided array. It will only compute as many hits as fit into the buffer, and store them in no particular order. It's not guaranteed that it will store only the closest hits. Generates no garbage.


public static function SphereCastNonAlloc(ray: Ray, radius: float, results: RaycastHit[], maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): int;
public static int SphereCastNonAlloc(Ray ray, float radius, RaycastHit[] results, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters

ray The starting point and direction of the ray into which the sphere sweep is cast.
radius The radius of the sphere.
results The buffer to save the results to.
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

int The amount of hits stored into the results buffer.

Description

Cast sphere along the direction and store the results into buffer.
