Monster run away from player

[bleson]

I need to make a monster run away [from the player]. The only thing I could find on the internet about this is a ZDoom flag called "FRIGHTENED", which doesn't actually work when tested with Zandronum (or I'm doing it wrong).
Do you know of any alternatives?

EDIT: Yes I've heard of the method of giving it a negative speed and reversing the sprites to create the illusion of running away, but that isn't suitable in my situation I'm afraid. Its facing direction does matter.

Check if the monster is frightened in it's missile/melee state, then if so, force it to run away. (AFAIK, you gotta define a new state that is different than see state otherwise it has a chance to enter infinite loop, that is, this new state doesn't make the monster go to it's melee/missile states)

Just to make sure, having the "FRIGHTENED" flag causes Zandronum to crash with an error message suggesting that it's an invalid identifier.

Really? Damn. You can check how KDIZD did it, they had a terror sphere which had the same effect on monsters. That should give you an idea, as I know it works in Zandronum. (At least 80% sure it works :P)

Give PowerFrightener

Just to make sure, having the "FRIGHTENED" flag causes Zandronum to crash with an error message suggesting that it's an invalid identifier.

FYI, this is not a crash. Zandronum informs you that the supplied DECORATE code is erroneous and exits gracefully.

There is a command to make monsters run away, and the command is "Anubis" :>

+FRIGHTENED works just fine in my wads for me.

[bleson]

Yep, sorry, my mistake!
+FRIGHTENED does work.

So I'd use A_ChangeFlag ("FRIGHTENED", 1) in its See state for it to run away, right?

[Ænima]

Correct.
