But the question for point 2 still remains: How do you save/load the entities? I used SceneComposer for specifying the game objects (visual + data) but this is not possible. Is there something like a best practice on how to specify the data.
Lets say you have a space cruiser with 5000 His and 4000 shields, 1500000 tons mass, 4000000 kN thrust, Antennas, Turrets with lasers, missiles etc… This data has to be specified and stored somehow. How is it done correctly? I assume that there would be something like a table/list (e.g. excel) providing all the data necessary for generating the object.
