Does anyone know a way to make an encounter truly invincible? The method I was using worked fine but I just learned they can be killed via the omnipotent cheat, and my map requires that the cheat be activated at different times throughout the game.

Make your weapon projectiles do no damage against your ally biped types.
It is impossible to make a biped invincible to omnipotent.

What is this for anyway?

or you could make a new actor variant tag and open it in guerrilla and scroll down and change the vitallity st uff to like, 9999

(object_cannot_take_damage (ai_actors [ai]))

Shields against the omnipotent cheat, though I'm unsure about the medusa cheat. To shield against that, you'll have to make the AI blind.

I tried that but it didn't work. Here is my script I'm not sure if I typed something wrong or what is going on.

(script startup allies
(object_cannot_take_damage (ai_actors encounter2))
)

Why didn't it work? Were the AI not invincible, or did the script not compile? If it was the former, you didn't compile the script correctly. If it was the latter, post your debug.

The script compiled but the ai can still die while onipotent is active

Yeah, omnipotent kills everything. Even invincible ai and object_cannot_take_damage guys.
I suggest finding an alternative to using omnipotent,

Any suggestions? I can't think of anything to try other than omnipotent for killing the ai.
