Hi there! I’m working on a basic custom JSON tilemap exporter just to export the specific properties of the maps that I’m interested in. However, the exported tile ID is always the local tile ID instead of the global tile ID that takes into account the tileset GID offset.
Now, that would be fine and I understand that the various flipped flags and tileset GID can simply be added to the tile ID to produce the correct global tile ID. However, when I attempted to re-configure the solution provided here for my own purposes, it seems the tilemap being passed to the exporter’s write function does not have any tilesets assigned to the tiles I get from the tilelayer.
Indeed, if I run this code to check:
for (let i = 0; i < map.layerCount; i++)
{
let layer = map.layerAt(i);
if (layer.isTileLayer)
{
for (let x = 0; x < layer.width; x++) {
for (let y = 0; y < layer.height; y++) {
let tile = layer.tileAt(x, y);
if (tile != null)
tiled.log("TileSet: " + (tile.tileset != null));
}
}
}
}
It tells me that every single tile on every layer has no tileset assigned:
I guess my question is is this a bug or am I perhaps misunderstanding the API or the data being passed during export? (Very possible). Any help is appreciated!
