Greetings everyone! I have been working on a drawing application in AS3 and have come to the determination that the dragging of items around on a canvas is best left to the drag manager. There are many things that the drag manager validates and handles for you that make the presentation smooth and happy.
What I am trying to accomplish is to constrain movement to 45 degree angle from a provided point. So that it can only be dropped on one of the cardinal points. If you have pressed shift while drawing a line in most drawing applications then you have most likely run into this. My thought was to extend the DragManager class to add in a point to its parameters that drag movement would be constrained to. Has anyone done or come across something like this? Have suggestions?
