Help & Support

var DoorOpener = pc.createScript('DoorOpener');

DoorOpener.attributes.add('Door', {type: 'entity'});

if(this.gameStarted === true)
    
  if (app.keyboard.isPressed(pc.KEY_E)) {
  this.Door.enabled = false;
 

   if (app.keyboard.isPressed(pc.KEY_Q)) 
   this.Door.enabled = true;

I have no clue why it is not working.
