Can't read Aseprite v1.3.5 (beta) file format

[kennedy0]

Platform: Microsoft Windows [Version 10.0.22621.3155]
LDtk Version: 1.5.3-64bits (build 473703)
Aseprite Version: v1.3.5 (This is the v1.3 Beta version on Steam)

Problem Description:
When creating a new tileset from an Asprite file saved with Aseprite v1.3.5, LDtk fails to read the file.

Steps to Reproduce:

1. Create a new LDtk project
2. Create a new tileset
3. In the File Open dialog, select an Aseprite file save with Aseprite v1.3.5 and click Open
4. An error message will appear saying "Warning, Couldn't read file":

Test files: ldtk_aseprite.zip

• tileset_v132.aseprite - A file saved with Aseprite v1.3.2 that imports successfully
• tileset_v135.aseprite - A file saved with Aseprite v1.3.5 that shows the above error

Workaround:
Reverting to Aseprite v1.3.2 and re-saving the file allows it to import.

There is no extra information in the log that I could find related to the problem:

Same problem here, can't work anymore with Aseprite 1.3.5 and Ldtk 1.5.3

[SnareChops]

For the workaround, now that the main Steam release is the 1.3.5 version, you can change which version you want installed by right clicking on Aseprite in your library, choosing "Properties" -> "Betas" -> "V1.3 - Previous Aseprite 1.3" to rollback to 1.3.2.

I had a similar error trying to use tilemaps (#479). As soon as I changed my layer from a tilemap to a standard layer, LDtk v1.5.3 seemed to work with Aseprite v1.3.5. Tile positions and IDs appear to be consistent within Aseprite so long as one doesn't delete or move them. Unfortunately, the Aseprite "packed" output doesn't appear to be ordered by ID so I'm unsure if it's stable. It may be possible to write an Aseprite script to generate a stable PNG output that LDtk can read.

Exporting by rows optionally with a fixed width appears stable.

This should be fixed with this commit I made in ase lib: https://github.com/deepnight/ase

I requested a merge to the official version: miriti/ase#4

Seem like aseprite devs just removed this beta from the steam version. RIP

Aseprite 1.3.5 support was fixed here: miriti/ase@9e15258

It will be part of LDtk next fix
