walking animation not activating.

Scripting Issues
1

Hello all, I am following along with Fireclaw the Fox’s book: “Panda 3D Game Development: Game Development for everyone” and I am stuck at the part of User Interactions. At the moment the character model does move, and also the model stops its idle animation when moving. However, the walking animation does not begin and the model is static while moving.

I need help figuring out what I am missing.

Here is the code:

        if speed != 0.0 and self.state != "Walk" and self.state != "Walk_back":

Thanks in advance.

Hi cgman64,

the animation IDs (like “Idle”, “Walk” and so on) you pass to the Actor class are as far as I know case sensitive, so try changing all of them to have the first letter being uppercase. So “walk” would become “Walk” for example.
