Is there some option to export tile layer data using a base of 0, instead of 1? I.e. In the exported data for a map, currently the first tile is referenced by an ID of 1: “layers”:[ { “data”:[1, 1, 1, 5, 7, 1, 1, 1, 1, 1, 1, 5, 7, 1, 2, 3, 1, 1, 1, 5, 7, 1, 5, 6, 1, 1, 1, 5, 7, 1, 5, 6, 1, 1, 2,…

[image] Eric_Richards: Working from most non-Lua languages, the first entry in an array/collection is 0, not 1, so I’ve got to fixup all these IDs when indexing into my texture atlases and other things. Actually this index also starts at 0, but 0 means “no tile” / “empty cell”. So if you’re g…

Thanks for the explanation. I still think it is a little confusing, especially since if I select a tile in Tiled, under the properties window for that tile, the ID field is 0-based, and doesn’t match up with the exported data. [tile-properties]

[image] Eric_Richards: I still think it is a little confusing, especially since if I select a tile in Tiled, under the properties window for that tile, the ID field is 0-based, and doesn’t match up with the exported data. Right, but that ID is local to the tileset. It’s an index into the arra…

today it took my quite some time that the layers.data numbers array isn’t linked to the id’s in the tiles array but rather to the index of said array, which confused me a lot. Is there a setting to make sure that these id’s start at 1 instead of 0?

Hi Bjorn, thank you for your quick reply! After using multiple layers, it dawned that the firstgid of every tilelayer is used in combination with the individual tile id to get a global id which is used in the layers.data array. This is why the first id starts at 1, because the firstgid starts at …

No. The global IDs don’t really exist in Tiled, they are only a mechanism used by the TMX and JSON formats to allow a map to use tiles from multiple tilesets.
