So whats happening is that Im trying to spawn in the correct amount of players into the level based on a Pnum integer in the InfoStore class. The Pnum is set by the P1 or P2 buttons. The problem is that it doesn't always work and it is buggy and just really doesn't work, but I'm not getting any errors or anything. Please help me solve this thanks!

Oh wait ignore the public InfoStore y in the buttons. forgot to remove that. Also, Im pretty sure the problem is with something in LevelBase

Would it not be wise to set the Pnum value in InfoStore before creating the worlds in the button classes?

In your P#but classes, you create the worlds on line 15, then ( later ??? ) on line 18, you set the number of players. The Level1 world constructor is using the value that is set to InfoStore.Pnum before you have it assigned its new (wanted) value.
