Setting different tilesets

[sssssssssss]

I can't believe I've forgotten this much, but here is the code first:

PHP Code:

//#CLIENTSIDE
function onPlayerEnters() {
// Set all Tilesets where needed
  removeTileDefs("");
  temp.haha= {
  "world_bb01.nw","world_bb02.nw","world_bb03.nw",
  "world_bc01.nw","world_bc02.nw","world_bc03.nw",
  "world_bd01.nw","world_bd02.nw","world_bd03.nw",
  "world_be01.nw","world_be02.nw","world_be03.nw"
  };
  //make haha tileset on world_aa01(top left) through
  //world_bf03(bottom right).
  
  if (player.level.name in temp.haha) {
    addTileDef("haha-tileset.gif", "world_", 1);
  }else{ 
    addTileDef("regular-tileset.gif", "world_", 1);
  }
  
} 


I can't even really think of a different way, but I know even I used to do it a different way. Obvously I need world_aa01 through world_bf03 one tileset and then the rest of world_ the regular tileset. Crappy doing it in onPlayerEnters too. :/
