public static Collider2D OverlapBox(Vector2 point, Vector2 size, float angle, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

Parameters

pointCenter of the box.
sizeSize of the box.
angleAngle of the box.
layerMaskFilter to check objects only on specific layers.
minDepthOnly include objects with a Z coordinate (depth) greater than this value.
maxDepthOnly include objects with a Z coordinate (depth) less than this value.

Returns

Collider2D The collider overlapping the box.

Description

Checks if a collider falls within a box area.

The box is defined by its center coordinate in world space and by its size. The optional layerMask allows the test to check only for objects on specific layers.

Although the Z axis is not relevant for rendering or collisions in 2D, you can use the minDepth and maxDepth parameters to filter objects based on their Z coordinate. If more than one collider falls within the box then the one returned will be the one with the lowest Z coordinate value. Null is returned if there are no colliders in the box.

public static int OverlapBox(Vector2 point, Vector2 size, float angle, ContactFilter2D contactFilter, Collider2D[] results);

Parameters

pointCenter of the box.
sizeSize of the box.
angleAngle of the box.
contactFilterThe contact filter used to filter the results differently, such as by layer mask, Z depth. Note that normal angle is not used for overlap testing.
resultsThe array to receive results. The size of the array determines the maximum number of results that can be returned.

Returns

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

Description

Checks if a collider falls within a box area.

The box is defined by its center coordinate in world space and by its size.

This function returns the number of colliders found and places those colliders in the results array. The results can also be filtered by the contactFilter. Note that filtering by normal angle is not available for overlap functions.
