Pair: addColPolygonPoint

This function is used to remove a point from an existing colshape polygon.

OOP Syntax Help! I don't understand this!

• Method:colshape:removePoint(...)

Syntax

bool removeColPolygonPoint ( colshape shape, int index )

Required Arguments

• 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

• bool: result

Returns true if the polygon was changed, false if invalid arguments were passed.
