General Question about Chao Raising

[strawberry-boyfriend]

This may have been asked before but okay for an analogy Bioware games have metrics that determine what your relationship with a companion is, and it visibly scales either visibly or invisibly

Do Chao have a similar mechanic for evolution? Is there a specific amount of petting required by heroes or villains? A certain amount of throwing against the wall? Do animals and energy drives (or whatever they're called) count?

I'm not too sure what you mean by the first part of your post, but I think I can answer your questions.

Yes, it does seem like you can count a specific amount of pets before your chao gains max friendliness/alignment towards a character. The easiest way to do this is by downloading Fusion's Chao Editor, and watching said stats change as you go.

The same obviously applies to throwing against the wall, and IIRC, animals and drives are the same way too.

If you can't access the editor, your chao's actions can also tell you how happy they are, too.

Unsure if this is what you're looking for, but:

Character bond is on a scale of either +100 or -100, beyond +50 and the Chao really likes you. This is increased by +1 each time a heart appears over their heads. It decreases when Chao are abused (-5 if thrown, -30 if attacked).
