A signal object is used when you want to synchronize multiple actions. You can create an action that waits on a signal object. You can then create an action that triggers a signal object. This way, multiple actions can be waiting on the same signal and they will all be activated simultaneously once the signal is triggered.
As a shortcut, the signal object already contains the actions to wait and trigger, <signal>.wait and <signal>.trigger. You can directly add these to an object instead of creating the actions using
<vizact>.waitsignal and
<vizact>.sendsignal.
#Create the signal object
sig = vizact.signal()
#Create an action to fade an object out
fadeout = vizact.fadeTo(0,time=1)
#Create an action to go to [10,0,0]
moveto = vizact.moveTo([10,0,0],speed=1)
#Add the actions to the objects.
#When 'object' is done moving it will trigger the signal.
#This will cause all the objects waiting on the signal to start fading out.
object.addAction(moveto)
object.addAction(sig.trigger)
object1.addAction(sig.wait)
object1.addAction(fadeout)
object2.addAction(sig.wait)
object2.addAction(fadeout)
object3.addAction(sig.wait)
object3.addAction(fadeout)
