i created an texture sheet with 1-1.png 1-2.png etc...
i got an error from the code. i used the mac version.
so i looked into in the tilessheet.txt and there was no 1-1.png they started with 1-2.png
i solved this problem i created an 0-1.png before 1-1.png and boom no 0-1.png but the 1-1.png was there.
it seems that the texture packer cut off the first position.
