It will loop a specific song depending on the biome you are currently in.
entered a forest- plays chirp
entered tundra- plays stal
BUT IT WILL PLAY SOMETHING ELSE WHEN YOU ARE UNDER y = 55 SO YOU CANT TELL WHAT BIOME YOU ARE IN!
*DUNATA TANAAAAAAAAA* (aka TF2 revenge sound) ((yes i play TF2 a lot deal with it))
BUT. ok ill stop with it...
anyways... make it so you could make it packs kinda like the texture packs work.
*press (insert random unused key that is most likely not comfortable to reach here) to chose a music pack*
BUT IT WI... sorry
It should also be able to be compatible with mods that add extra biomes, like biomesXL ETC ETC
a .txt file or an in game window where you could type the name of the biome and the music you would like to play.
