Object animation using a picture?
 

I need to animate a picture such that it moves forward a bit and backward a bit. Kind of like a moving room. I'm having trouble; here's what I've got:

import viz

tex1 = viz.add('picture.jpg')
quad = viz.add(viz.TEXQUAD)
quad.translate(0,1,12)
quad.scale(12.8, 10.24)
quad.texture(tex1)

moveForward = vizact.move(0,0,2,5)
moveBackward = vizact.move(0,0,-2,5)
#tex1.add(moveForward)
#tex1.add(moveBackward)
MovingRoom = vizact.sequence(moveForward,moveBackward,4)


def onkeydown(key):
if key == ' ':
tex1.add(MovingRoom)

viz.callback(viz.KEYDOWN_EVENT,onkeydown)

But when I run the script I get this error message:
Traceback (most recent call last):
File "Moving Room 3.py", line 25, in onkeydown
tex1.add(MovingRoom)
AttributeError: VizTexture instance has no attribute 'add'

Which, I guess, makes sense to me. But I wondering if there is a way around this. Like, how can I make it such that the picture moves forward X distance for Y duration and then backward X distance for Y duration...etc (i.e. put that in a loop/timer). Namely, I'd like the picture to keep moving forward and backward the entire time the script is running.

Thanks for the help.

You almost had it. You need to add the MovingRoom action to the quad, not the texture. Your code should look something like this:

Thank you for your help. It makes so much sense in retrospect.
