Changing Joystick navigation halfway through
 

Hi there,

In this setup, the user must navigate using a joystick. When the viewpoint collides with an invisible torus, I want the joystick navigation speed to change. Everything else in the simulation runs on a sequence of tasks, so I tried creating a variable and changing it in one of the tasks, but it's not working. Here's what I have so far:

import vizjoy
joystick = vizjoy.add()

randommove = random.uniform(.01, .0300) # Random float x, 1.0 <= x < 10.0
randommove2 = random.uniform(.001, .0002)

def mytimer(num): #configure joystick navigation
global MOVESPEED
MOVESPEED = randommove
y = sid.get()[1]
x = sid.get()[0]
twist = (180.0 / math.pi) * (sid.aux()[3])
if math.fabs(y) > 0.5:
viz.move(0,0,-y*MOVESPEED)
if math.fabs(x) > 0.5:
viz.move(x*MOVESPEED,0,0)
if math.fabs(twist) > 20:
viz.rotate(viz.BODY_ORI,twist/50.0,0,0)

viz.callback(viz.TIMER_EVENT,mytimer)
viz.starttimer(0,0.001,viz.FOREVER)


def update_mytimer_task():
yield viztask.waitEvent( viz.COLLISION_EVENT )
global MOVESPEED
MOVESPEED = randommove2


def torus_collision_task():
yield viztask.waitEvent( viz.COLLISION_EVENT ) #colliding with the #torus also causes a blank screen to appear with instructions

def train():
blank_screen.visible( viz.OFF )
torus_collision = viztask.waitTask( torus_collision_task() )
update_mytimer = viztask.waitTask( update_mytimer_task() )
data = viz.Data()
yield viztask.waitAll( [torus_collision, update_mytimer] )
blank_screen.visible( viz.ON )
blank_screen.alpha(.6)
text2 = viz.addText('Reproduce the distance you just walked \n\nand press "s" when finished',viz.SCREEN)
text2.alignment( viz.TEXT_CENTER_CENTER )
text2.setPosition( .5,.5 )
text2.setScale(.5,.5)
text2.color(viz.YELLOW)
text2.setBackdrop(viz.BACKDROP_RIGHT_BOTTOM)
text2.resolution(1)
text2.alpha(1)
sphere.visible(viz.OFF)
yield viztask.waitTime( 2 )
blank_screen.visible(viz.OFF)
text2.visible(viz.OFF)
torus.remove()

any ideas for getting the navigation speed to change after the collision?

thanks!

Please wrap code with code tags to preserve indentation. Here's some example code that changes the speed based on a collision with an object that is not rendered:
If you use torus.visible(viz.OFF) the collision event will not get generated.
