<window>.isCulled help

[BSUGeek]

Hi everyone,

I'm trying to figure out this <window>.isCulled stuff. I'm just testing it out right now. I have an avatar not in view when the world opens. He then begins to walk until he is in view. and I want the program to print out I see you but nothing is happening once the avatar walks into view. any help will be greatly appreciated.

avatar = viz.addAvatar('vcc_male2.cfg',pos=[-2,0,0])

if(viz.MainWindow.isCulled(avatar)==0): 
	print 'I See You'
