Make something do a 180 after touching a wall?

However, isn't there a way to have a projectile set its spawner as the target (In fact, I thought that was the default)? So, you could just use A_GiveToTarget in the death state. Maybe.

I think so, although I get mixed up with target and "tracer" on projectiles, and I think there's been some talk lately of possibly changing / extending that whole mess somehow.

Here's a variation on that - if the imps are going in a straight line, the invisible projectile could shoot a hitscan in the opposite direction when it hits a wall. The hitscan would have a custom damage type that causes imps to turn around.

Even more hacky! Well done.

Too hacky, especially since it could harm other imps and make them turn!

Heh, you're no fun. Hell, I was almost going to suggest having the thing set off a radius attack with said custom damage, that way whole groups of the things would turn around as they got close... but i don't think you can put custom damage on a radius attack (right?)

Nevermind I sorted it. I used a short range bullet attack which makes a puff which uses a tiny A_Explode with a damage type "turn" and the imp has a pain state for turn which loads script 99 which makes him turn 180 degrees...

oh, cool, so explosions can have custom damage =)

Great! Now all you need to do is figure out how to gives imps umbrellas or drills, and how to make the geometry in a Doom level destructable.

Giving the lemming crap: Custom damage types
Destructible terrain: Probably models or something. Obviously I can't make entire levels destructible.
