Creating new levels in infinite numbers.

#
I made some function to go from a level to another but the way I made it I can't have more than two levels.. How can I adjust my code to make it work for an infinite number of levels?

I think the best way would be to use not a string but an int for the level number (instead of currentLevel == "noGameStarted" you just have currentLevel = 0 or any other number). That will make it more easy. Then you check whether there are no enemies in the world. If there are no you count up the level number and start the new level (using the level number: if (level == 1) { } else if (level == 2) ...)

Thx for the tips! I added also the checkForNextLevel() in the act method to make it more easy. It looks like that now:
