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

파라미터

pointCentre of the circle.
radiusThe radius of the circle.
layerMaskFilter to check objects only on specific layers.
minDepthOnly include objects with a Z coordinate (depth) greater than or equal to this value.
maxDepthOnly include objects with a Z coordinate (depth) less than or equal to this value.

Collider2D The collider overlapping the circle.

설명

Checks if a collider falls within a circular area.

The circle is defined by its centre coordinate in world space and by its radius. 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 circle then the one returned will be the one with the lowest Z coordinate value. Null is returned if there are no colliders in the circle.

public static int OverlapCircle (Vector2 point, float radius, ContactFilter2D contactFilter, Collider2D[] results);

파라미터

pointCentre of the circle.
radiusThe radius of the circle.
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.

반환

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

설명

Checks if a collider is within a circular area.

The circle is defined by its centre coordinate in world space and by its radius.

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.


public static int OverlapCircle (Vector2 point, float radius, ContactFilter2D contactFilter, List<Collider2D> results);

파라미터

pointCentre of the circle.
radiusThe radius of the circle.
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 list to receive results.

반환

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

설명

Checks if a Collider is within a circular area.

The circle is defined by its centre coordinate in world space and by its radius.

The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.

The results can also be filtered by the contactFilter.

Note that filtering by normal angle is not available for overlap functions.
