PhysicsShapeGroup2D.GetShape

参数

返回

PhysicsShape2D Returns the shape stored at the specified shapeIndex.

描述

Gets the PhysicsShape2D stored at the specified shapeIndex.

NOTE: Because the PhysicsShape2D is a struct, this is a copy of the shape therefore changing the shape afterwards will not change the PhysicsShapeGroup2D.
