Hi,

I want to push a button with my mouse and afterthat my object should rotate for a special amount.

This works, but I had to push the button again and again.

Code:

def onButton(obj,state):

  if obj == scene3.btnLeftRotate1:

    if state == viz.DOWN:

      object1.rotate(-1,0,0,'',viz.RELATIVE_LOCAL)



viz.callback(viz.BUTTON_EVENT,onButton)

I want to push the button one-time with my mouse and as long as I hold the button pressed, the object should move on and on.

You can use the vizact library to enable a timer while the button is down. Here is a simple script showing how to do this:

Code:

import viz

import vizact

viz.go()



# Create model

model = viz.add('logo.ive',pos=(0,1,5))



# Create function to rotate model

def RotateModel():

        model.setEuler(90*viz.elapsed(),0,0,viz.REL_LOCAL)

        

# Create disabled timer to call RotateModel function

rotateTimer = vizact.ontimer(0,RotateModel)

rotateTimer.setEnabled(False)



# Create button

rotateButton = viz.addButton(pos=(0.9,0.1,0))



# Enable rotate timer while button is pressed

vizact.onbuttondown(rotateButton,rotateTimer.setEnabled,True)

vizact.onbuttonup(rotateButton,rotateTimer.setEnabled,False)
