I would add 2 games attributes. One for storing x coordinate, another for y coordinate. Let's call them here Xgame, Ygame.
What you want to do is:
- do not set the actor on manually (in the scene), but do it via code
- in the second scene, when actor is leaving, you need to set Xgame, Ygame to proper values (those would be x/y of position where you want the actor to appear in the first scene)
- in the first scene, make a scene behaviour that "when created" creates your hero at Xgame, Ygame. The little bit tricky part is to make it also work when you first start the game. Assuming you have some kind of menu scene, you would need to set Xgame, Ygame when player press "start game" or something similar, before the menu scene goes away and first scene is loaded.
That's how I would do it, but keep in mind I'm not an expert.
