Don't mind the mess!
We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.

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 Program
Update the Code
Now that the scenery is in place, we will load an Actor. Update your code to look like this:
from math import pi, sin, cos from direct.showbase.ShowBase import ShowBase from direct.task import Task from direct.actor.Actor import Actor class MyApp(ShowBase): def __init__(self): ShowBase.__init__(self) # Load the environment model. self.scene = self.loader.loadModel("models/environment") # Reparent the model to render. self.scene.reparentTo(self.render) # Apply scale and position transforms on the model. self.scene.setScale(0.25, 0.25, 0.25) self.scene.setPos(-8, 42, 0) # Add the spinCameraTask procedure to the task manager. self.taskMgr.add(self.spinCameraTask, "SpinCameraTask") # Load and transform the panda actor. self.pandaActor = Actor("models/panda-model", {"walk": "models/panda-walk4"}) self.pandaActor.setScale(0.005, 0.005, 0.005) self.pandaActor.reparentTo(self.render) # Loop its animation. self.pandaActor.loop("walk") # Define a procedure to move the camera. def spinCameraTask(self, task): angleDegrees = task.time * 6.0 angleRadians = angleDegrees * (pi / 180.0) self.camera.setPos(20 * sin(angleRadians), -20.0 * cos(angleRadians), 3) self.camera.setHpr(angleDegrees, 0, 0) return Task.cont app = MyApp() app.run()
The command loop("walk") causes the walk animation to begin looping.
Run the Program
The result is a panda walking in place as if on a treadmill:
