Hello again, after searching for quite some time and beating my noggin' against the table a couple of times I couldn't find a solution to my problem.
It's quite simple and I think I might have asked it before but the link to the .capx was broken.
As you can see with this expertly-made illustration, the arm's angle is always towards the mouse, but if I mirror the player and the arm, the arm aims inverse.
There's an extremely simple fix to this problem, obviously, but I can't for the life of me figure it out.
Thanks in advance.
