Wrong ID number for tilesets based on tilesets image about sktiled HOT 4 CLOSED

Do you have a sample scene you can send me to illustrate the problem?

The global id (gid) represents the tile data's internal id plus the tileset's firstGID value. Internally, the tileset stores tile data in an array starting with 0 with the upper bound being the number of tiles.

The value stored in the map file is the global id, so the SKTileset.getLocalID(forGlobalID :) method is used to resolve the global id → local id.

Ok Michael, I've created a repository to reproduce this bug with a README that show all images:

https://github.com/aornano/SKTiledBugged

This tileset started with ID 0 for the first upper left tile.
As you can see to these screenshots , I've try to put the grass tile as showed in the editor but in the app it appear with the previous tile (the grass with the stones).
So it takes the ID 3 instead of ID 4.

That's the tilesets TSX file (xml) file :

<?xml version="1.0" encoding="UTF-8"?>
<tileset version="1.4" tiledversion="1.4.2" name="grass1" tilewidth="128" tileheight="64" margin="1" tilecount="9" columns="3">
 <image source="handpainted.png" width="512" height="256"/>
</tileset>

Thank you for your reply!

Ok I've found the problem.

This issue is not from your code, your code is correct.

The problem is the default value of TiledMap Editor v1.4.2 when you create the TSX file:

So this is not a bug, this report can be closed. Thank you.

The problem actually lies within your tileset file.

I noticed in your second post that the image you were loading was too large for a 3x3 tileset at 128x64px. I changed this...

<?xml version="1.0" encoding="UTF-8"?>
<tileset version="1.4" tiledversion="1.4.2" name="grass1" tilewidth="128" tileheight="64" margin="1" tilecount="9" columns="3">
 <image source="handpainted.png" width="512" height="256"/>
</tileset>

... to this...

<?xml version="1.0" encoding="UTF-8"?>
<tileset version="1.4" tiledversion="1.4.2" name="grass1" tilewidth="128" tileheight="64" tilecount="16" columns="4">
 <image source="handpainted.png" width="512" height="256"/>
</tileset>

...and the preview in Tiled now matches what you're seeing in your iOS app:

When the SKTileset loads in your source spritesheet image, I'm calculating the bounding rect for each tile based on the total tile count, the source image dimensions and spacing/margin values. So in SKTiled, the tile with id 3 is actually this guy:

Bjorn is creating his tileset images a little differently, so you've given me a great use-case for reviewing how we calculate our tile breakup 😉

Technically, this is a bug so I'll keep it closed, but will add it to the list of things to fix.
