I wanna move a turret on a really thin wire, but the problem is it gets stuck sometimes if i just use a tiny hitTest.

So looking for any ideas on a way to set it out, how can i get it accurately snapping too it?, more a logic problem then i can do the coding, tho you can add it if you want to help. ideas? ima just stumped atm

i dont think a hit test would be best for this. why not just make it so each point the lines cross you have it recorded on an array, like a map so you know which way you can turn. its hard for me to explain really. hope you understand a little :S
