Problem description:

I was playing around with a movement style where the player mob follows the mouse around the map. I noticed when you use any auto-walk processes, like walk_to() for example, it only brings the mob to the very edge of the source atom. I understand there's the parameters, including icon-x and icon-y, but to use those wouldn't I have to recreate an automated moving system?

TL;DR:
How do I get the user to follow the mouse around the map PIXEL-PERFECT? I know I'll probably have to be using MouseMove(), which isn't very good, but this is just for tests.
