Well, the enemy will chase the player when it's healthy and then run when it's hurt. That bit's working, at least. But the attacks just aren't going right. Unfortunately, it's a game in a fighting arena! The fighting is the whole point! And that's the bit that doesn't work right. Which isn't much of a surprise, since I've never done anything quite like this, and also left it for last. But still, it'd be nice if it was at least somewhat playable.

The way it works now, the enemy will get right up close, not face the right direction (likely because of colliders), and then attack like crazy. And because they're the same speed as the player, you can't really escape them. Once they get close, they're sticking right to you forever.

The way I'd like it to work is to have the enemy get close to the player, maybe attack a few times, then sort of back off a bit so the player has to come towards them for a bit more challenge. I'm really not sure how to do that, though, or even what exactly I want.

It's pretty clear at this point that I'm going to have to settle, with so little time left and having other things to do. I think I'm going to go for giving the player the ability to sprint so the player can get away from the enemy, and then seeing if turning off some colliders makes the enemy actually face the right direction. But if anyone has any ideas or tips for how to do attack AI, I would absolutely welcome them!

EDIT: It was absolutely the colliders, the weapon handles (especially the spear!) were pushing the player away and making everything impossible. Turning them off made a big difference!
