Loading and Animating the Panda Model¶
Actors¶
The Actor
class is for animated models. Note
that we use loadModel()
for static
models and Actor
only when they are animated.
The two constructor arguments for the Actor
class are the name of the file containing the model and a Python dictionary
containing the names of the files containing the animations.

The command loop("walk")
causes
the walk animation to begin looping.
