Use two ammo with one shot?

[schilcote]

Long story short, I need my weapon, which takes multiple types of ammo, to fire two shots at once while consuming two units of ammo at once. How do I go about this?

Should be possible with OnFire event? I've forgotten the details, but you probably can use the event to generate another shot from a virtual weapon (or a copy of the current weapon's shot), and at the same time delete one ammo of the chosen type from the ship's inventory. Before this, you can do a check to see if there are at least 2 ammo left in the inventory, and make the weapon not fire if there aren't.

Does the weapon consume one ammo type two at a time, or two types of ammo one at a time each?

Either way, it is definitely possible and not too hard with the OnWeaponFire event, but it may be a little tricky for UI-friendliness if your weapon needs to eat more than one ammo type at the same time.

I'm not sure if this is exactly what you want but:

in a very cheap way you could in the <OnWeaponFire> event of the weapon:

(objGetProperty gSource 'selectedMissile)
this will return the itmStruct of the currently selected missile in your launcher.
so you can manually remove 1 missile from the cargo hold and the weapon will basically consume 2 ammo.

I have done that in my mods already, but I am not sure if what the OP wants is consume two of one ammo type or one ammo from two separate types. If he wants the latter, it is a bit trickier to implement (I have not done that before, but I have an idea how).

There's a multiverse library for that.

You want AU_multishotammohandler if you're making a launcher or AU_initializeunlauncher, AU_virtualammoupdate, and AU_fireunlauncher if you want a non-launcher weapon that handles multiple ammo types. The latter system invokes the former if AU_fireunlauncher is called with two arguments.

It's a double-barrel missile launcher. It's supposed to use two units of the same kind of ammo.

This:

Code: Select all

<OnFireWeapon>
				(block Nil
					(unconventionalWeaponOnFire 20000)
					(objRemoveItem gSource (objGetProperty gSource 'selectedMissile) 1) ;We only remove one 'cos we already removed one as part of being fired
					Nil
				)
			</OnFireWeapon>

SHOULD work but it actually takes THREE missiles, which is downright bizzare.

EDIT:

That's happening because OnFireWeapon gets called twice, one for each missile. Hmm.

EDIT:

There's a multiverse library for that.

How do I actually use that? Just slotting a <Library unid="..."> declaration right below the opening <TranscendenceExtension> doesn't do it. How do I make the game download the library?

[PM]

<OnFireWeapon> is called once for each shot in your configuration. If you have two shots, the event is called twice per attack.

The game automatically subtracts one ammo per attack, independently of events.

One of the calls to OnFireWeapon event should not remove ammo. The remaining calls should.

You need to keep track of shots fired.

Also, when weapons is damaged or ionizated, and it misfires, events are not called, but you still lose one ammo.

The game should just download libraries used in enabled mods if you're connected to the multiverse and don't have them.
