[0.11.2] Rats Cant Climb Stairs

[Teralitha]

Not sure if this has always been the usual behavior for rats, but I only just noticed they cant climb stairs. I suppose this is why most places have ramps instead of stairs.

Just checked, and they can climb stairs in classic.

So its a bug then.

Thanks for checking Pango. Will move to bug reports so we can investigate later.

I tried changing the option for improved combat AI to see if that caused it but made no difference. The stairs have a weird shape though, and that may have something to do with it.

Yeah, stairs suck in Daggerfall. They're all kinds of weird in terms of riser and tread ratio, and don't have nice physics meshes to help traverse. Everything is scooting around on raw arbitrary geometry which is painful to code for.

My guess is that rats are having troubles because their collider height relative to stair riser height is beyond the controller's maximum step property. Hopefully it's something we can tune out without breaking something else.
