My shotgun can still be selected with 0 ammo

[Jekyll Grim Payne]

It's not a huge problem but it's weird, and I can't figure out why it's the case.

The properties are as follows

Code: Select all

Actor BD_Shotgun : Shotgun replaces Shotgun
{
weapon.selectionorder 130
inventory.pickupsound "weapons/shotgun/pump"
attacksound ""
+NOALERT //for melee
weapon.slotnumber 3
weapon.slotpriority 1
States
	{
...
	}
}

The alternative attack is a melee attack that doesn't use any ammo. However, I thought that since I don't have ALT_AMMO_OPTIONAL, the shotgun will become unavailable as soon as its main ammo is. But it doesn't seem to be the case: it can be selected without ammo. How come?

P.S. I can post the states code but I don't think anything there could affect that.

There. This is why. If you think about it, the chainsaw, for instance, doesn't use ammo, yet you can still select and use it. It's the same thing here. Your weapon can always be selected because its alt fire is always usable, even if you can't use its primary fire due to lack of ammo.

I thought that since I don't have ALT_AMMO_OPTIONAL, the shotgun will become unavailable as soon as its main ammo is.

Since the weapon doesn't utilize a secondary ammo type, setting or clearing that flag doesn't change anything.

Is there any way to block the selection when it runs out of primary ammo type?

The trick I was shown was giving it the flag WEAPON.AMMO_CHECKBOTH. The wiki says you need to give both ammo types a positive AmmoUse value, but there's nothing stopping you from setting it to 1 and then setting any attack functions to not use ammo.
