So I was following this guy's tutorial on how to create the Super Mario Bros game, and I was wondering how it would be possible to change levels (screens), in the tutorial he creates a PlayScreen, I was wondering if when I create a class like "level2" I could make it extend from the playscreen and only change the file that the tmx map loader uses, I thought about doing a whole nem class with all the already created functions and just change the file, but there's other classes that uses the PlayScreen as a reference (B2WorldCreator). I know how I would do to end the level, I would do a object that when in colision would trigger the setScreen method.
(PLAYSCREEN)
