Python Programming Question

[jaylocco]

Im sory to ask this because Im still new to Python. but is there such a thing as 'nested While' in Python just like in C++? Im trying to loop a vizard game which contain a 'while true:' loop. the thing is, how do I repeat the whole program. this is the sample programming code.

    def game()
        
        yield viztask.waitKeyDown(' ') #<----starts the game
	#fade intro page
	fadeOut = vizact.fadeTo(0,begin=1,time=1)
	startpage.addAction(fadeOut)
	#call throwing function
	throwing ()
	viz.phys.setGravity(0,0,0)

        while True: # this while loop will repeat the flying Aliens to and fro
		FlyAliens() #flies the Aa Bb Cc Aliens
                ResetPositionAliens()     
     myTask = viztask.schedule( game() )

Aliens= [Aa,Bb,Cc]
Ship.enable(viz.COLLIDE_NOTIFY)
		
def oncollide (e) :	
	
	if e.obj2 in Aliens:

		Ship.visible(viz.OFF)
		Shipcrash.visible(viz.ON)
		view.lookat([2,0,-5])
               

viz.callback(viz.COLLIDE_BEGIN_EVENT,oncollide)

Let say if the ship collide with any of the aliens, the ship will crashes down and it will prompt user whether to replay again or not.

So how do we reset the game by using another while loop by pressing the 'r' button ( yield viztask.waitKeyDown('r') ) and back to the beginning. (#<----starts the game)

There seems to be a problem with your current code. The while loop inside your game task is not yielding. This will probably cause the graphics loop to freeze. It seems like there should be a yield None statement at the end of the loop.

Regarding your original question. You can setup a simple callback function that restarts the game task when the 'r' key is pressed. Example:

def ResetGame():
	global myTask
	myTask.kill() # Kill existing task
	myTask = viztask.schedule( game() ) # Create new game task
	
vizact.onkeydown('r',ResetGame)

Thanks..especially for the reset function that u suggested.it makes my life easier..
