AI script command for items with multiple abilities (Ring of Gaxx, etc)

[misterslack]

How do I select an item's particular ability for use in an AI script? For example, the Ring of Gaxx can cast both Improved Haste and Improved Invisibility, however UseItem("RING39", Myself) only uses the invisibility. I don't see any command in the IESDP and I cannot find an example script that does what I'm talking about. I tried SelectWeaponAbility and that didn't work. Any help would be greatly appreciated.

I don't believe you can do it through scripting. At least, I've never been able to get it to work. Kensai Ryu had a lich script that supposedly did some fancy stuff with a staff of the magi, but I never saw it in action.

34 UseItemSlot(O:Target*, I:Slot*) ?

It only works for items with only one special ability. BTW, "allirpM".rev() did a "breakthrough discovery" in his s u p e r s c r i p t s, by emulating the various items' abilities with SpellNoDec.

34 UseItemSlot(O:Target*, I:Slot*) ?

This is just I:Slot*SLOTS (so you can say "use the item in slot RING_LEFT" without knowing exactly what resref is in that slot).

Change UseItemSlot(O:Target*, I:Slot*) to UseItemSlot(O:Target*,I:Slot*SLOTS,I:AbilityNum*), and you could use all three item abilities in scripts. You still have to know in which slot the item is.

Huh, i thought i had the bright idea to actually implement this in gemrb.

I didn't know the original engine does it too

 

On the other hand, UseItemSlot and UseItem share the SAME opcode.

So, if the analogy works completely, then you could use this too

34 UseItem(S:Object*,O:Target*,I:Ability)

 

See

97 UseItemPoint(S:Item,P:Target*,I:Ability*)

So, if the analogy works completely, then you could use this too

34 UseItem(S:Object*,O:Target*,I:Ability)

Tested, it doesn't work.
