I'm trying to figure out a way to change the level in my game, I've got level 1 & 2 as subclasses of World, trying to figure out where to put the loop that checks the condition that if there's no fruit left, the next world will load with more fruit to eat and another enemy to dodge. I've hardcoded the amount of fruit and enemies in the level 2 because I'm only going to have about 5 levels, would like to increase the speed as well per level but not necessary at this point.
Have included LevelOne, LevelTwo, Player, Fruit and Counter (even though it only displays the score). I've commented in the code where I've tried things, any help would be appreciated.
