From Multi Theft Auto: Wiki
bool removeColPolygonPoint ( colshape shape, int index )
OOP Syntax Help! I don't understand this!
- shape: The colshape polygon you wish to remove a point from.
- index: The index of the point you wish to remove. The points are indexed in order, with 1 being the first bound point. You can't remove the last 3 points.
Returns true if the polygon was changed, false if invalid arguments were passed.
