i have 2 proton cannons and 2 lazer cannons and 2 engions... what kind of hp_things are needed... oh .. and do you like my model... took like 3 hours... and not finished yet.. of corse

Good looking model! I'm working on a tank myself and I'm having trouble understanding how HPs work... sorry I can't answer your question, but I wanted to say you've got a good model!

Nice looking model. As for hard points (these are all just nulls just rename them as required) you would need
hp_pilot positioned where the pilot would sit
hp_fire, hp_fire1 etc for as many weapons you intend to have. Place at the end of the barrel for the weapon
hp_exhaust, hp_exhaust1 etc if you intend to have exhaust. Place at the exhaust ports of the engines
hp_damage, hp_damage1 etc these can be put at various places on the model where you would like the damage effect to appear
hp_active usually goes the same place as the dummyroot null

that should be a good enough start

Not to hijack, but do ALL of those need to be put on?

Only if you want it to be realistic

Which are needed, and which aren't?(imagination time, yay Bes'uliik)

You don't need any of them but then everything relates back to the dummyroot.
Minimum you should have for a flyer is hp_pilot and assuming you intend to have weapons hp_fire

Omg! Why couldn't you tell me that before in my thread?! That makes more sense now!

ty , great help, im workining on an arwing

You won't need a hp_pilot if your pilot isn't actually going to be seen, and you definitely don't need a hp_active.

So if you're going to make a weaponless ship, you don't really need any of these at all?
