Hi,

The command viz.pause will freeze all current timers, which can later be resumed with viz.play(). This doesn't stop keyboard and mouse events though. An alternative might look something like this:

def StopEvents():
	viz.callback(viz.KEYBOARD_EVENT,0)
	viz.callback(viz.TIMER_EVENT,0)
	viz.callback(viz.MOUSEDOWN_EVENT,0)

def ResumeEvents():
	viz.callback(viz.KEYBOARD_EVENT,onkeydown)
	viz.callback(viz.TIMER_EVENT,ontimer)
	viz.callback(viz.MOUSEDOWN_EVENT,onmousedown)

You can then use these functions to freeze/resume input.

To display text to the user you can create a text object like so:

text = viz.add(viz.TEXT3D,'Thank you for your participation',viz.SCREEN)
#Place in the middle of the screen
text.translate(0.5,0.5)
#Set alignment to center of message
text.alignment(viz.TEXT_CENTER_CENTER)
#Initially hide the text
text.visible(0)

When you want to display the message to the user simply make the text visible.
