Drag and drop with easeljs in Animate CC 2017

Question

I\'ve been using an HTML Canvas project in Adobe Animate CC 2015.2 to drag around a movieClip on the stage, using the method recommended in the creatjs Mouse Interaction Tut

Answer 1

I think I've sorted the problem. The following seems to work on both Animate CC 2015.2 and Animate CC 2017 irrespective of OS and display resolution.

this.my_mc.on("pressmove", function(evt){
    var p = stage.globalToLocal(evt.stageX, evt.stageY);
    evt.currentTarget.x = p.x;
    evt.currentTarget.y = p.y;
});

I still have to get my head around why the change was necessary in Animate 2017 and not in Animate CC 2015.2 (scratches head).

Thanks,

Dave
