Hi Cade,
Can you try the following code. I tried it here and it works fine. Also, make sure that you aren't changing the visiblity of the objects somewhere else in your code. Just press the spacebar. The label should disappear and a quad should show up 2 seconds later.
Code:
import viz
viz.go()
label = viz.add(viz.TEXT3D,'Label',viz.SCREEN)
label.translate(0.5,0.5)
label.alignment(viz.TEXT_CENTER_CENTER)
quad = viz.add(viz.TEXQUAD,viz.SCREEN)
quad.translate(0.5,0.2)
quad.visible(viz.OFF)
def viewPic():
label.visible(viz.OFF)
viz.waittime(2)
#quad.texture(pics[0])
quad.visible(viz.ON)
def onkeydown(key):
if key == ' ':
viz.director(viewPic)
viz.callback(viz.KEYDOWN_EVENT,onkeydown)
