Yes those were the 2 options I've been thinking about, I already worked with the blink but didnt like it since it always went in a single repeated direction, it was not really feeling as if the monster was running away in a clever way, I thought about an other way to make them flee, it works like the blink but is smoother, I just gave the monster some negative movement speed, that way it looks more like hes running away (worked well with a single faced monster like the slime and have yet to try with a 8 faces monster), combining it with blink feels great and gives it the opportunity to escape corners and walls when it's stuck.
**EDIT** Just tried a 8 faces monster and it works like a charm, he's turning it's back on the character to run away
Awesome!!
