about an exercise in "Vizard Teacher in a book"

I meet some problem in texture part (maybe in page 32)

The exercise is "1. Add the "art/wall.ive" model to a world, add the "art/stone wall.jpg" texture and apply it to that model."

However based on the example above the exercise I cannot get the right things I want

The example is like

import viz
viz.go()
viz.MainView.setPosition( 0, .65,-1.3 )
model = viz.add('art/wall.ive')
window = model.getChild( 'glass' )
walls = viz.addTexture('art/tileclouds.jpg')
moon = viz.addTexture('art/full moon.jpg')
window.texture( walls, '', 1 )
window.texture( moon, '', 0 )

#clouds.wrap( viz.WRAP_S, viz.REPEAT )
#clouds.wrap( viz.WRAP_T, viz.REPEAT )
#slider = viz.addSlider()
#slider.setPosition(.5,.1)
#def swap_textures( slider_position ):
#cloud_amt = slider_position
#window.texblend( cloud_amt, '', 1 )
#vizact.onslider( slider, swap_textures )
#swap_textures(0)
#matrix = vizmat.Transform()
#def move_clouds():
#matrix.postTrans(.0005,.0005,0)
#window.texmat( matrix, '', 1 )
#vizact.ontimer( .01, move_clouds )

I got some confusion about the "sub-nodes" part

Is there anyone can teach me about this example?

Wish to get some help from the forum......

Are you trying to modify the example code included in the tutorial? The original code adds a window model that has a glass sub-part:

Code:

#Add a model and grab one of its chidren to put the textures on.

model = viz.add('art/window.ive')

window = model.getChild( 'glass' )

If you open the 'window' model in Inspector you'll see the scene graph and model sub-parts. In your code 'window' was swapped with 'wall'. The 'wall' model does not have a sub-part called 'glass'.

Yeah I find out that and I now figure out the problem
