avatar walkto interrupt

Hello,

This maybeIs there a way to stop an avatar that's walking from point A to point B "dead in it's tracks"?

My code untill now looks somewhat like this:

Code:
def walk1():
	yield viztask.waitKeyDown( ' ' )
	yield viztask.addAction(avatar, vizact.walkTo([pointA]))
	yield viztask.addAction(avatar, vizact.walkTo([pointB]))
	yield viztask.addAction(avatar, vizact.walkTo([pointC]))
               avatar.state(14)
	yield viztask.waitTime(10)
	viztask.schedule(walk2())

def walk2():
	yield viztask.waitKeyDown( ' ' )
	yield viztask.addAction(avatar, vizact.walkTo([pointD]))
	yield viztask.addAction(avatar, vizact.walkTo([pointE]))
               avatar.state(14)
	yield viztask.waitTime(10)
#main
viztask.schedule(walk1())
So during ANY of the walkto actions i want to be able to stop the avatar where he is, and let him perform some kind of action on that spot.

In the following example the spacebar is used to start and stop the avatar as he walks between two points:
Code:
import viz
import viztask
import vizact
viz.go()

viz.add('ground.osgb')
avatar = viz.addAvatar('vcc_male2.cfg',pos=[0,0,9])
avatar.state(1)

walkLeft = vizact.walkTo([2.5,0,9])
walkRight = vizact.walkTo([-2.5,0,9])
walkActions = viz.cycle([walkLeft,walkRight])

waitSpaceBar = viztask.waitKeyDown(' ')
waitLeft = viztask.waitActionEnd(avatar,walkLeft)
waitRight = viztask.waitActionEnd(avatar,walkRight)
waitActions = viz.cycle([waitLeft,waitRight])

def walkAndStopTask():
	yield waitSpaceBar
	while True:
		condition = waitSpaceBar
		walkAction = walkActions.next()
		waitAction = waitActions.next()
		while condition == waitSpaceBar:
			avatar.runAction(walkAction)
			d = yield viztask.waitAny([waitSpaceBar,waitAction])
			condition = d.condition
			if condition == waitSpaceBar:
				avatar.clearActions()
				yield waitSpaceBar
			
viztask.schedule(walkAndStopTask())

Thanks for your reply Jeff. I've tried the "clearactions()" statement.
However, since i'm using schedule to arrange the actions, i have to kill that as well to prevent the other walking actions from running.

I've tried this:

Code:
def walk1():
	yield viztask.waitKeyDown( ' ' )
	yield viztask.addAction(avatar, vizact.walkTo([pointA]))
	yield viztask.addAction(avatar, vizact.walkTo([pointB]))
	yield viztask.addAction(avatar, vizact.walkTo([pointC]))
               avatar.state(14)
	yield viztask.waitTime(10)
	viztask.schedule(walk2())

def walk2():
	yield viztask.waitKeyDown( ' ' )
	yield viztask.addAction(avatar, vizact.walkTo([pointD]))
	yield viztask.addAction(avatar, vizact.walkTo([pointE]))
               avatar.state(14)
	yield viztask.waitTime(10)

def stop():
	avatar.clearactions(0)

#main
t = viztask.schedule(walk1())

vizact.onkeydown('l',t.kill)
vizact.onkeydown('k',stop)
And this works, it stops the avatar completely and he returns to his idle state. However, it is inconvenient to have to push 2 keys to stop the avatar, so i tried to add the killing of the schedule to my stop command:

Code:
def stop():
               t.kill
	avatar.clearactions(0)

vizact.onkeydown('k',stop)
But this doesn't work for me, Is there a way to combine the 2 commands? I feel i'm overlooking something very simple here, but i can't quite put my finger on it.

Once the user stops the avatar, what is the next action that should be applied to the avatar? If the avatar stops on the way to PointA, should he pick up from the same place later and continue to PointA, or go to PointB, or should the whole task be ended?

Jeff, i'm writing some software for a military simulation, the avatar actually gets shot and killed.
So the whole task should be ended, i would like the avatar to assume a specific state (lie down) and perform no actions anymore after that.

Not to sound too desperate, but i'm still having some difficulties with this. Does anybody perhaps have a suggestion for me?

If you're waiting for either the walk action to finish or the keypress to occur you should use the viztask.waitAny command. Then if the event was a keypress you can leave the task using the return command:
Code:
d = yield viztask.waitAny([waitSpaceBar,waitAction])
condition = d.condition
if condition == waitSpaceBar:
	avatar.clearActions()
	return
