| shapeIndex | The index of the shape stored in the PhysicsShapeGroup2D. The shape index is zero-based with the shape group having a quantity of shapes specified by shapeCount. |
| vertexIndex | The index of the shape vertex stored in the PhysicsShapeGroup2D. The vertex index is zero-based with the shape having a quantity of vertex specified by PhysicsShape2D.vertexCount. |
| vertex | The value to set the shape vertex to. |
Sets a single vertex of a shape.
NOTE: When accessing multiple vertices, it is more efficient to do one of the following:
