stop physic

[nlfrnassimi]

Hi,

I have created a simple bouncing ball. I want it to stop when it reaches a particular point. But I don't know how. I'll appreciate any help.

Here is my code for ball:


import viz

viz.go()

viz.phys.enable()

ground = viz.add('tut_ground.wrl') # Add ground
ground.collidePlane() # Make collideable plane
ball = viz.add('ball.wrl',pos=[0,.2,6]) # Add a ball
ballPhys = ball.collideSphere(bounce = 2) # Enable physics on ball
ball.applyForce([0,.3,.2],0.5) # Apply small force for half a second

You could use a timer and get the position of the ball. Once its position has reached the point you specify you can either disable physics for the scene

viz.phys.disable()

or for just the ball

ball.disable(viz.PHYSICS)

Can you please tell me how should I use the timer to get the ball position?

Thanks alot

When the z coordinate of the ball is greater than 10 it will stop

def stopball():
	
	pos = ball.getPosition()
	if pos[2] > 10:
		ball.disable(viz.PHYSICS)
	
	
vizact.ontimer(0,stopball)

Thanks alot for your help
