I would prefer if, assuming they can cast the spells, a witch would use hunger/hygiene/bladder charms autonomously, rather than seek out food/shower/toilet. The spells are already allowed as autonomous, but I have yet to see my witch sim use them autonomously.

I know for a fact they don't cast them autonomously, cuz most of my sims are witches, and all they ever do is stand around pissing themselves.

I wonder if the Naughty Sims Asylum modders have made anything. [EDIT] Hrm, not finding anything, sadly.

@MeMyselfAnDie and @murfee - I've done a quick test and I was able to make the motive charms autonomous by changing the advertising for spell casting and adding some for hygiene, bladder and hunger. It really needs more testing, because I'm not sure if they'd prefer casting over using available commodities in their vicinity, but I'd be willing to share with you if you wanted to check?

Sounds exciting!
I'm a crap tester candidate though, since I don't get to play often, being stuck in UNI hell all frikkin week.

I had the time to do some more testing and I think I found the right advertising values so that sims will prefer to cast over anything. I attached to file to the post if you wanted it and I've also added another package if you wanted the Motive Charm to use less magic (about a third of the original amount). :)

Now, I wonder if I should also add advertising for fun, social and energy if I wanted to use it in combination with Shimrod's New Motive Charms and Curses Unlocked mod...
