i have two timers, one that listens for certain keyboard input, and another that makes a person walk around in my world. I want the first one to be always on, but is there a way to make the second one start after a certain elapsed time, say 5 seconds or so? here's what my timer function looks like:

Code:

def mytimer(num):

        if num == 0:

                brake = 0

                if viz.iskeydown(viz.KEY_TAB):

                        brake = 1

                if viz.iskeydown(viz.KEY_UP) and brake != 1:

                        view.move(0,0,MOVE_SPEED*viz.elapsed(),viz.BODY_ORI)

                        car2.translate(0,0,MOVE_SPEED*viz.elapsed(),viz.RELATIVE)

                elif viz.iskeydown(viz.KEY_DOWN):

                        view.move(0,0,-MOVE_SPEED*viz.elapsed(),viz.BODY_ORI)

                        car2.translate(0,0,-MOVE_SPEED*viz.elapsed(),viz.RELATIVE)

                if viz.iskeydown(viz.KEY_RIGHT):

                        view.rotate(0,1,0,TURN_SPEED*viz.elapsed(),viz.BODY_ORI,viz.RELATIVE_WORLD)

                elif viz.iskeydown(viz.KEY_LEFT):

                        view.rotate(0,1,0,-TURN_SPEED*viz.elapsed(),viz.BODY_ORI,viz.RELATIVE_WORLD)

                updatecar()

        # puts the walker on the screen        

        if num == 1:

                walker.visible(viz.ON)

                global walkerX, walkerY, walkerZ, walkerAngle

                walker.rotate(0,1,0,90)

                # calculate components of motion w.r.t X and Z axis

                walkerZ = walkerZ - 0.00002 * math.sin(math.radians(walkerAngle))

                walkerX = walkerX + 0.00002 * math.cos(math.radians(walkerAngle))

                # move the walker

                walker.translate(walkerX,walkerY,walkerZ,viz.RELATIVE)



                



viz.callback(viz.TIMER_EVENT,mytimer)

viz.starttimer(0,0.01,viz.FOREVER)

viz.starttimer(1,0,viz.PERPETUAL)

A timer starts whenever you call viz.starttimer(), so your goal is to decide when it's appropriate to make that call.

Something like this sketch (this is not tested code):

Code:

timer_one = False



def mytimer(num):

        if num == 0:

                if not timer_one and viz.get(viz.FRAME_TIMESTAMP) > 5.0:

                        timer_one = True

                        viz.starttimer(1, 0, viz.PERPETUAL)

                # do other timer-zero stuff

        if num == 1:

                # do other timer-one stuff



viz.callback(viz.TIMER_EVENT, mytimer)

viz.starttimer(0, 0.01, viz.FOREVER)

when I try to run that I get this error:

if not timer_one and viz.get(viz.FRAME_TIMESTAMP) > 5.0:
AttributeError: 'module' object has no attribute 'FRAME_TIMESTAMP'

You can also use the Python time module.

Code:

import time



#Gives number of seconds since program start

print time.clock()

ok that seems to work fine, thanks!
