So for my main menu I wanna get to adding in some music so I feel achieved and I can say I have worked with sound. I am doing most things right like having my file location correctly, but I get this error on start up:

From what I understand is that it can't read the .ogg file which confuses me. I declared an object of Music, said the file location in the init() and then did <variable>.loop() also in init after the file location. Is there any way you guys can help point me out on how to fix this. Also if somebody could help teach how to do a separate Input class and Button class that can detect collisions.
Thanks,

Looks like it can't find the jorbis library.
Have you set up the jorbis jar correctly on your build-path?

So I got JOrbis and that fixed the error, but now when I use it it plays through all the states. So is there possibly anyway to fix this, I know the enter() and leave(), but where do I call them on the start up of a state.

Enter and leave are called automatically, as you switch state with StateBasedGame.enterState(), first leave() is called on the old state, then enter() is called on the new state, just make sure you override them correctly in your gamestates.

I am not allowed to put @Override methods on them with out giving me an error saying there is no need for them. I put the methods in there and they don't seem to be getting called because the music doesn't play in the enter method. Also would you possibly know a good jump algorithm for when a player jumps?

Are you sure you override them correctly, in the correct place(BasicGame or BasicGameState)?
post the full gamestate?

And about your other question, you should create a new topic for that one, where you explain what kind of game you are making and how you want the jumping to work, since a jumping algorithm can be quite game specific. :)
