Laser Pointer Updated

import viz	
viz.go()

Height = viz.input('Height?')
print "Participant's height is", Height, "inches."

Meters = (Height * (1.0/39.37)) 
print "Participant's height is", Meters, "meters."

RedDot = viz.add(viz.TEXT3D, '.', viz.SCREEN)
RedDot.translate(0.5, 0.57, 0)
RedDot.alignment(viz.TEXT_CENTER_CENTER)
RedDot.color(1,0,0)	# Red
#RedDot.scale(.5, .5, .5)

Ok...so here's my "deal." The RedDotis supposed to mimic the laser pointer (which is going to be positioned on top of a person's head. So I was trying to come up with a way to input how tall the person is, convert it to meters (if necessary), and then use that height to position the RedDot. So instead of

RedDot.translate(0.5, 0.57, 0)

I want: RedDot.translate(0.5, Meters, 0)

That way I can customize the height of the laser pointer in Vizard to each individual's personal height.

Also, do you know why this line:

Meters = (Height * (1.0/39.37))

keeps getting highlighted yellow without giving me an error message every time I run the script? Is something wrong with it?

This is a side effect with the way Vizard 2.5 ran scripts. You can ignore it as long as it runs fine.

[Elittdogg]

Thank you. It runs fine so I have been ignoring it. But my original question still stands...how can I get it so that the laser pointer is set to the height of the participant???

[farshizzo]

I don't understand what you are trying to accomplish. How are you relating a persons height to screen coordinates?

[Elittdogg]

I'm trying to mimic a real setting where a laser pointer would be fixed on top of a person's head and therefore the "height" or the "coordinates" of the laser would chance from participant to participant. I'm looking for a way to be able to enter the participant's height and then use that input to determine where the laser pointer in Vizard should be.

Does that make more sense?
