Physics2D.OverlapBoxNonAlloc

Switch to Manual
public static int OverlapBoxNonAlloc (Vector2 point, Vector2 size, float angle, Collider2D[] results, int layerMask= DefaultRaycastLayers, float minDepth= -Mathf.Infinity, float maxDepth= Mathf.Infinity);

Parameters

pointThe center of the box.
sizeThe size of the box.
angleThe angle of the box.
resultsArray to receive results.
layerMask@param layerMask Фильтр для обнаружения коллайдеров только на определённых слоях.
minDepth@param minDepth Включает только объекты с координатой Z (глубиной) выше, чем это значение.
maxDepth@param maxDepth Включает только объекты с координатой Z (глубиной) меньше, чем это значение.

Returns

int Returns the number of results placed in the results array.

Description

Get a list of all colliders that fall within a box area.

This function is similar to OverlapBoxAll except that the results are returned in the supplied array. The integer return value is the number of objects that fall within the box (possibly zero) but the results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved when the check is performed frequently.
