No it's more what — said. But my problem is ok i'm in world menu, I select a level 1 so I do a "go to layout > level 1"and then the game "freeze" when he change layout. So I can put a animated screen for the loading but he will not be animated because of the "freeze" time.
I don't know if there is a possibility to load the level and have the animated screen while waiting for the level finish to load.
Like the Loader Layout of Construct where you see the loading percentage.
