Where does equipping logic happen?

For an Equipment like Ring of Thune, where is the logic that determines what creature the AI attaches it to?
I looked everywhere I could think of but couldn't find what code was actually doing it.

The Equip macro is handled in CardFactoryUtil, from line 4652. You probably just need to add a split so that you can specify a preferred AI target in the form of AITgts$ Card.valid, then just append that to the ability string.

I decided to go ahead and do it myself. The M13 rings are done, but if you come across any other equipment that needs preferred targeting for the AI (or any other additional params, just add the new params after the equip cost. It'll take everything after the first "|" and add it to the generated Attach script. Eg: Ring of Thune now has this:

Code: Select all

K:Equip 1 | AITgts$ Creature.White

and the generated script is

Code: Select all

AB$ Attach | Cost$ 1 | AITgts$ Creature.White | ValidTgts$ Creature.YouCtrl | TgtPrompt$ Select target creature you control | SorcerySpeed$ True | Equip$ True | AILogic$ Pump | IsPresent$ Card.Self+nonCreature | PrecostDesc$ Equip | SpellDescription$ (Attach to target creature you control. Equip only as a sorcery.)

I see now, thanks. I didn't understand anything about the CardFactoryUtil and how it generates that script, so it took me forever to figure out that the logic ends up in AbilityFactoryAttach.

Now the AI will never attach the Rings to a different-colored creature. I think that's OK here since the other abilities are pretty tricky to use correctly (Hexproof, Haste). I think the +1/+1 counters are what will actually be useful to the AI.
