Hardpoints should automatically attack any enemy unit in range.
And as for the missile thing, I have an idea...in the hardpoint or projectile coding (I think hardpoint) set it to only target "Missile" in something like (it should have Capital, Frigate, etc. remove those and put MISSILE, and it should target missiles. The question is if said missiles have a collision mesh for being hit by projectiles, but I'll leave that to you)
The lines i were looking for are: True True
I still however don't know how to get them to fire at missiles :\ and i doubt it Sith. I was thinking if i can find a way to make it something like that but wouldn't that require a new model in that case?
Maybe, maybe not. Try it.
Sorry for the long response delay. Happy new years btw. If i was to get a new model for it wouldn't it pretty much be a kamikaze "fighter"? I don't think this would work as you would have to make some way for the missile/kamikaze "fighter" to go for ships and explode and cause damage somehow...I tried adding it to the and that didn't work so i tried to change it from MISSILE to Fighter and that still didn't work...anymore ideas? Im trying to think of ideas but so far im blank on what to try now.
