I would try to solve the whole thing with an AI_Relationship, but I don't know if you can use an AI_Relationship to tell an NPC to see a barrel as an enemy.

Here I once explained to someone how to make it so that NPc`s do not attack you

Normally it should be possible to assign an AI_Relationship to the barrel and as soon as a zombie runs into a trigger (trap) or however it triggers this relationship ob the combine (where you can set if hate, neutral, like etc . The Target for sure the barrel then).

But never tried, just an Idea. I haven't tried anything with the Hammer Editor for a very long time.

Hello Schranzi, i thank you for taking your time. i was not able to use the ai_relationship to make the grunt hostile toward the barrel. but your sugestion inspired me to think a bit outside the box.

here is my protype solution if your interested. i dont know if its pratical in a actual game situation. ( why is it so hard to do this? i can force the grund to throw a grenade or launch a manhack. but simply target and shoot a designated area is impossible. in hl2 ther was a sniper_target for the npc_sniper (or something like that). but in alyx its different. anyway.)

the goal: force the combine to shoot the barrel to create the impression he uses the enviroment to fight the enemy.
the solution: i spawn a invisbile npc_headcrab inside the barrel. combine automatically fight headcrabs.

possible implementation: i imagine a set of traps like the explosive barrels, the npc_combine_s can activate against other npc_enemy. by shooting or using abutton.
for emample:
-electrical devices that creates sparks.
-gas, water, steam leaks that create a damageeffect
-droping physical objects taht hang around.
-releasing objects that roll down a slope. (logs, a truck, rocks)
-breaking and destroying specific objects likes crates, bottles and windows
-and so on
