Better to post text as text instead of screenshots.
X2 frameworks expects a single Game class. All the calls from the game loop to the game class are direct calls.
You can create two instances of the game class and change their behavior based on a value you pass to the initialize method.
Thanks for the info and I will check if I got that right.
Let's assume two screens next to each other. A Splitt Screen. Showing different parts of the tilemap. A single X2.UpdateWorldCenter will be difficult.
Or I want to use a tilemap as a moving background in a different screen than the actual game.
