Physics Problem

[Sandro Holzer]

Hello Everybody

I have a problem with the Physic Engine.

In the following code I want to push away the red box (seesaw from tutorial) with the last of the 3 bars, which are moveable by pressing the keys.

Is this possible with the moving of the bars controlled by their angles?

import viz
viz.go()
viz.phys.enable()    
viz.clearcolor(0.1,0.1,1)
ground = viz.add('tut_ground.wrl')
ground.collidePlane()
ANCHOR_POS= (0.6,1.8005,6)
bar1 = viz.add('bar2.obj',pos=ANCHOR_POS)
bar2 = bar1.add('bar2.obj')
bar2.translate([0.0,0.0,-1])


bar3 = bar2.add('bar2.obj')
bar3.translate([0.0,0.0,-1])
bar3.collideBox()
bar3.disable(viz.DYNAMICS)

seesaw = viz.add( 'box.wrl' )
seesaw.scale( 1, 1, 1 )#
seesaw.translate(0,3,5)
seesaw.collideBox(bounce=0.8)

a = 0
b = 0
c = 0

def mytimer(num):
	global a,b,c
	if viz.iskeydown('t'):
		a = a + 1
		if a > 89:
			a = 89
		
		move()
	if viz.iskeydown('b'):
		a = a - 1
		if a < -89:
			a = -89
		move()
		
	if viz.iskeydown('f'):
		b = b + 1
		if b > 89:
			b = 89
		move()
	if viz.iskeydown('h'):
		b = b - 1
		if b < -89:
			b = -89
		move()
		
	if viz.iskeydown('z'):
		c = c + 1
		if c > 89:
			c = 89
		move()
	if viz.iskeydown('n'):
		c = c - 1
		if c < -89:
			c = -89
		move()

def move():
	
	euler = bar1.getEuler(viz.ABS_GLOBAL)
	euler[0] = a
	bar1.setEuler(euler,viz.ABS_GLOBAL)
	
	euler = bar2.getEuler(viz.ABS_GLOBAL)
	euler[1] = b
	bar2.setEuler(euler,viz.ABS_GLOBAL)
	
	euler = bar3.getEuler(viz.ABS_GLOBAL)
	euler[1] = c
	bar3.setEuler(euler,viz.ABS_GLOBAL)
