[RGSS]Event is facing? Options

[Redd]

Is there a little scriplet someone could make that checks which direction the current event is facing? So that I can use it in a Conditional Branch?
I'm trying to make a "stealth kill" system (along with the Stealth/Detection Script) that makes it so that if you sneak up from behind someone you can use your equipped weapon to kill them sneakily. Problem is, there's only a "Player is facing" condition in Conditional Branch.
So what I'm asking for is, a script call that would determine which way the current event is facing (up, down, left, or right) so that you could assassinate them.

Credits will be given Thanks!

The guard looks in different directions and some of them move though, so that would be quite cumbersome.
I could do variables, but I would have to have a different variable for each guard and that would not end up a happy time.
