Is it possible to use a SEXP or a table edit to limit the ammunition in a cap ship turret?  I would love cap ship turrets that run out of ammo.

Lock them after x seconds.

[killface]

Well, there is always that.      Any way to ACTUALLY limit ammunition on turrets?

[blowfish]

Yeah, there's a way.  You have to give all of the weapons a cargo size in the table, and then give the turret pbank ammo or sbank ammo.  Note that how much ammo a turret has can be modified in any mission.

Hmmm, I knew about the cargo size thing, but the pbank / sbank ammo is new to me.  What about this: is it possible to define a SEXP that can check for a turret's ammunition level?  Basically I want a capital ship to have to warp out once its turrets are depleted or near-depleted.

Untested, aside from checking for any real big syntax errors.

EDIT: I don't know how Lua will handle things if AmmoMax is <= 0, so that would probably need to be updated if some of the turrets on a ship don't have ammo-limited guns.

EDIT 2: Forgot to index by 1 rather than 0. Fixed in the example.
