Just register the timer in your keyboard callback:
Code:
def timer1():
print 'Elapsed time:',viz.elapsed(), 'seconds'
def onkeydown(key):
if key == ' ':
quad.add(MovingRoom)
vizact.ontimer(60,timer1)
Also, in the future please use the [code][/code] tags when posting code snippets. It preserves the indentation, which is necessary for python scripts.
