Physics.SphereCastNonAlloc

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

Parameters

originThe center of the sphere at the start of the sweep.
radiusThe radius of the sphere.
directionThe direction in which to sweep the sphere.
resultsThe buffer to save the hits into.
maxDistance@param distance Длина луча.
layerMaskA Layer mask that is used to selectively ignore colliders when casting a sphere.
queryTriggerInteractionSpecifies 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.
