Detailed Description

The SceneChangeNotifier JavaScript class. Execute client code upon scene change events.

User can connect a function to any available signal from this class. Once a function is connected to a signal, the client code will be executed when the specific event is triggered in the scene, until the parent object is destroyed.

Example with a MasterController:

Controller.onShowControl = function()
{
  //Create the SceneChangeNotifier, using the Controller for parent
  var scn = new SceneChangeNotifier(Controller);
  
  //Connect a local function to "nodeChanged" signal.
  //The connected function will be executed when the signal is triggered,
  //for as long as the parent object is alive (until the Controller is hidden).
  scn.nodeChanged.connect( function(nodeList)
  {
    MessageLog.trace("nodeChanged Callback!");
    for(var i=0; i < nodeList.length; ++i)
    {
      MessageLog.trace("    affected node: " + nodeList[i] );
     }
  });
}

Example with a Dialog:

this.setupUI = function()
{
  this.ui = UiLoader.load( this.getLibPath()+"/TB_InterpolationSlider.ui");
  var scn = new SceneChangeNotifier(this.ui);
  scn.currentFrameChanged.connect( function()
  {
    //Code your callback logic here...
    MessageLog.trace("currentFrameChanged Callback!");
  });
};
