Yield until joystick is deflected by a certain degree
I've read the example scripts of yield statement, but I don't know how to realize this function: The function won't go to the next line until the user deflected the joystick beyond a certain degree. Here's my code:
HTML Code:
def pointing_task(joystick) some codes return angle,result ##result is false means the joystick isn't deflected beyond a certain threshold def start_pointing(): angle,result = pointing_task(joystick) yield result == True ?? some codes viztask.schedule(start_pointing()) Thanks a lot! |

have the pointing_task method be a loop that constantly is checking for joystick position. waits a few ms, then checks again.
something like while( joystick position is not facing the right way) yield viz.waittime(.01) #i forget the method This way the loop will keep going and only exit until and continue with the rest of the program when the joystick is in position. the yield statement in the method makes other yield statement calling it actually wait and pause the program. (dont know why vizard does it this way but thats just how it is) |
