Im trying to load info from the text file using tokenization and use that to set tile type, needless to say it doesnt work, giving a nullpointerexception at at 114 (or the renderinuse part). Im exhausted so I cant explain more, but all help appreciated, this one has been annoying me for a while now. I can update it later, thanks again.
