I need to create several levels with function. Levels have the same function and different names.
But filling levels should be done from external data.
How to do it?
Level Blueprint is exclusivly for level scripting exlusive to that level, if you want code that do something that works on every level you need to do it in more global class, like GameMode. Fact that you trying to copy level blueprints it a good sign you need to move it to somewhere else then level blueprint.
