Why wont hostiles attack my aircraft?

i know ive asked this before. but how can i get hostiles to attack my aircraft with triggers? which ones do i need?


ive put that trigger in, but they still wont attack.

@indy22334 If your ‘hostiles’ are AI planes and tanks then go to their UnitProperties and scroll down to Attack Type and chage it to ‘fire_at_will’ or ‘fire_at_will_air’.
If you want them to target other AI/Bots to then go to bottom and click on ‘targetableByAi’ and when they get close to each other they’ll shoot each other as well.

I’d setup a 'unitrestor’e trigger so they’ll respawn when they get killed.
