First of all I really like the this engine. Especially because of the extensibility... Based on the easy handling json structure you can put every kind of engine in it. Another thing I like about this engine is the great editor. Because its possible to easily add stuff and orientate.
But now lets turn to my question. Can someone maybe be so kind and show me an example how I can add dynamically objects to a scene. I tried already some stuff but it seems nothing is working... I worked previously with phaserjs, threejs, cocos2dx, SDL, but I miss something like append/addObject. Whats the proper way in that case?
