error while setting material properties.

[Chandan]

Hi,

I get the following error while trying to set material attributes like sethardness()

the function is called as follows an example code:

import viz
import vizmat

viz.go()

viz.translate(viz.HEAD_POS,0,5,-10)
viz.lookat(0,0,0)

ground = viz.add('ground.wrl')
ground.collideplane()

ball = viz.add('ball.wrl')
ball.collidesphere()
ball.sethardness(0.1)


ball.reset()
ground.reset()

ball.translate(0,10,0)
ball.scale(0.6,0.6,0.6)

viz.phys.enable()


When I try to run this code, I get the following error:


Scaling image 'worlds/yellow.GIF' from (640,400) to (512,512)
Traceback (most recent call last):
