How do I make an enemy move away from an object upon contact

Hey, I've been making a zelda clone and this is what I've got so far: h t t p s ://vine.co/v/OV3adl6DOOK

I want to make it so that the enemy jumps in the opposite direction when it gets hit by the magic attack. I'm pretty sure this is where Custom Movements come in handy, but the manual isn't very helpful. Any clue?

use set vector X or Y action

in 8 Direction? I can't, because I need the enemy to move in the opposite direction of the attack, and the attack could come in any direction. Unless I'm wrong, vector X or Y only lets you move in specific directions.

I'm going through the manual again. If anyone has an idea, please speak up!

I can't find anything in the manual that applies here. Any help?

When your character hits an enemy, you need to find the angle between the enemy and the character, then move the enemy 180 degrees from that angle.

I've never used the 8 direction behaviour, so the logic may need some tweaking based on it's properties. Sorry, I'm not at home so I can't work out a more elegant solution for you.
