You should be getting another error message before the one you posted. What does that one say? What kind of object is the view object? The easiest way for me to solve the problem would be if you posted an entire script that reproduces the error.

for this code, view is just the vizard mainview:
view = viz.MainView

here is a stripped down version of the code. there are a few models at the top which can be replaced with a generic ground. basically, there is a ground with a pit in it, and we want people to have the view of falling into the pit. i'd also like to have them pop back up when they get out of the range of the pit. it works fine on keyboard control but not when using the tracker:
import viz
import vizact
import time
import math
import random
import winsound

ground = viz.add('Models/ground_2m.ive')
pit = viz.add('Models/ground_pit_new.ive')

#Select this for single-monitor desktop use...
#viz.go(viz.FULLSCREEN)
#OR select these for HMD/dual-monitor use:
viz.go(viz.STEREO | viz.FULLSCREEN)


light1 = viz.addLight() #Add an overhead light
light1.setEuler(0,90,0)
## Prompt for the participant's identification number - generally keep this uncommented! ##
keyControl = viz.input('Using Tracker? 1 = Yes, 2 = No')
#subject = viz.input('What is the participant number?')
if keyControl == 1:
eyeohd = viz.input('What is the participants IOD?')

#HMD field of view: (vert. FOV, aspect ratio H:V)
#viz.fov(53,1.1887) #Kaiser SR80 specs
viz.fov(43,1.395) #Cybermind specs

##Rename the main view ##
view = viz.MainView
#Link viewpoint with tracker, initialize boresite
if keyControl == 1: #If you're using the tracker
headTrack = viz.addSensor('intersense')#Ignore documentation stating you need "intersense.dls" - this is correct
linkedTracker = viz.link(headTrack, view) #Link the sensor to the view.
linkedTracker.preTrans([0,-.15,.14]) #Boresite function - translates the viewpoint from the tracker position to eyepoint position
# viz.link(headTrack, view) #Link the sensor to the view.
viz.eyeheight(0.0)
view.translate(0,-.19,.14) #Boresite function - translates the viewpoint from the tracker position to eyepoint position
viz.ipd(eyeohd/100.0)

You need to post the code using the [code][/code] tags. This will preserve the indentation, which is necessary for running Python code.

I get a syntax error when trying to run your code. It doesn't seem like you used the [code][/code] tags. Just copy the contents of your script and paste them in between the tags.

are there additional tags to indicate that the code is starting and ending? they are not clearly marked in any of the message options.
