displaying random scenes etc

[cl113]

i am a beginner and i am terrible at programming and am quite confused.

1. is there any way, after creating multiple scenes, that one can randomly select which scene to display using vizact.choice or something else?

2. does vizact.choice randomly choose from a list and then stop when all the list items have been chosen, or does it continue to choose from the list?

3. also, is there a specific command that allows you to reflect an object's position about a specific axis?

the online reference is not helping and any help would be much appreciated!!!!!!!!

You could randomly select a scene using the random module to generate a random integer and then set the scene to that number.

import viz
import random
viz.go()

#add three objects to three different scenes
duck = viz.add('duck.wrl',scene = 1)
wheelbarrow = viz.add('wheelbarrow.ive',scene=2)
wheelbarrow = viz.add('ball.wrl',scene=3)

viz.MainView.move(0,-1,-7)

def changeScene():
	num = random.randint(1,3)
	viz.scene(num)

vizact.ontimer(2, changeScene)

To get an objects position use

object.getPosition()

That will return a list with x,y,z position of the object.
