I have been using game maker for a while now. I have a pretty good understanding of the mechanics now. However, Gamemaker is still a black box. What I would like to know is which functions are more CPU efficient than others. For example, if I do a draw_somthing is that more or less efficient than tilemap_set. What about an instance of an object. Is that better than a point_in_rectangle on a drawing? Idon'treally require a direct example for each, allthough this would be very helpful. My question is how do I know for sure which functions are more efficient than another.
