problem when using the sample roaming ralph

When I try to use the code of the sample Roaming ralph, I met some errors. I don’t know which part was wrong.
I didn’t change other code of the sample, just changethe model into mine.
self.ralph = Actor(“models/ralph”,
self.ralph = Actor(“models/cat”,

but it does not work.

It looks as though our cat model doesn’t have animations (hence the error “models/cat is not a character”). Did you create any animations with it? If so, then what sort of animations did you use, with what names, and how did you export the model?

Thanks. The problem is I export the animations in a wrong way. Now it works.
