public int GetPath(int index, Vector2[] points);

Parameters

indexThe index of the path from 0 to pathCount minus 1.
pointsAn ordered array of the vertices (points) in the selected path.

Returns

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

Description

Gets a path from the Collider by its index.

A path is a cyclic sequence of line segments between points that define the outline of the Collider. Since the Collider can have holes and discontinuous parts, its shape is not necessarily defined by a single path.

Returns the number of points placed in the points array.

See Also: GetPathPointCount & pathCount.


public int GetPath(int index, List<Vector2> points);

Parameters

indexThe index of the path from 0 to pathCount minus 1.
pointsAn ordered list of the vertices (points) in the selected path.

Returns

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

Description

Gets a path from the Collider by its index.

A path is a cyclic sequence of line segments between points that define the outline of the Collider. Since the Collider can have holes and discontinuous parts, its shape is not necessarily defined by a single path.

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.
