Hello! I’m new to tiled but was asked to create a map using it, I’m just a pixel artist not a programmer.
There’s this issue that I’m getting. I am working on creating a map and exported the final file in .JSON like the dev asked me but they just told me that these blue squares appeared only on tiles I flipped using tiled. Is there a way to fix this? The blue squares don’t appear on my original file only on the .JSON I sent to the dev.
They asked me to redo all the flipped tiles and add them to the tile map but is that the only way to fix this?
When you say JSON, do you mean TMJ, or a different JSON-based format?
If the blue appears only in-engine and not if you open the JSON in Tiled, the problem is most likely with either the engine the dev is using, or with how they’re loading the file. They might not be reading the flip information correctly, and may thus be trying to render non-existent tiles.
The dev asked me for a JSON so instead of exporting a .TMJ I added a .JSON in the end of the file which seems to work but he is now encountering this issue is there a way for him to fix it easier than me adding the tiles?
If you just changed the extension, that’s still a TMJ, just with a JSON extension (it is JSON, but there are many different tilemap formats that are JSON-based, TMJ is just one).
The fix is something for the dev to implement, and the nature of it will depend on why the flipped tiles aren’t being read correctly. Make sure the dev looks at the Global Tile ID page in the docs, which explains how flipping should be handled: Global Tile IDs — Tiled 1.11.0 documentation
The most likely scenario is they’re not reading and clearing the flip flags from the tile IDs. If they fix that and render flipped tiles as flipped tiles instead of as invalid tiles, that should make your maps usable in the game without any fixes on your end.
If the reason they’re not handling the flipped tiles correctly is because the engine doesn’t support flipping tiles (rare, but it does happen), then there is no fix, you would need to replace all flipped tiles with different, unflipped tiles.
