shapeIndex | The index of the shape to be modified that is stored the PhysicsShapeGroup2D. |
useAdjacentStart | Sets the PhysicsShape2D.useAdjacentStart property of the selected shape. |
useAdjacentEnd | Sets the PhysicsShape2D.useAdjacentEnd property of the selected shape. |
adjacentStart | Sets the PhysicsShape2D.adjacentStart property of the selected shape. |
adjacentEnd | Sets the PhysicsShape2D.adjacentEnd property of the selected shape. |
Sets the adjacent vertices of a shape.
NOTE: Calling this on a PhysicsShape2D that does not have a shapeType of PhysicsShapeType2D.Edges will result in an exception being thrown.
