json skeleton height and width showing as zero.

eventhorizon02

Hi,
I'm trying to figure out what am I doing wrong.
I have two skeletons in one project, one is the side view of my character and the other is a back view.
When I export the project in json format I get two json files. The one for the side view has the correct skeleton width and height but the one for the back view is printing 0 for both height and view.
What could be causing this issue?

Thanks

Mario

Which Spine editor version are you using?

I'm using 3.2.01

This has been fixed in 3.5.16, see JSON export in 3.4.02 sets width/height to 0 · #111 · EsotericSoftware/spine-editor. If you can not upgrade to this Spine Editor version, you can calculate the setup pose bounding box via code (which is a better solution than relying on the bounds from the JSON file anyways!).

Hello Esoterics.

I would like to re-open this bug.
I am using version 3.6.52, on Windows 10 (also tried on 7).

The "width" and "height" skeleton parameters at the start of the .json file are sometimes set to zero, and sometimes show a specific size.
I am trying to export a project with multiple skeletons.

So far, after trying the export on different machines, with different export settings, with also trying to split the project into single-skeleton projects before export, the following 'magic' sequence of actions seems to ensure a proper export:

Make one failed export attempt (where the json lists skeleton size as zero).
Double-click a mesh in the tree window.
Hit "Ok" without entering a new name for the mesh.
Switch to "Animate" view.
Open the export dialogue.
Uncheck "Pretty print".
Browse to a new folder.
Wait 5 seconds.
Click the "Export" button.

Skipping any of the steps seems to ensure a failed export.

Could you send us one of your project files? contact@esotericsoftware.com (please reference this thread).

Hello! we managed to repro the bug of zero lenght and width, but if you make sure to have all skeletons visible, save the project, and then export, it should work fine.
We're working on it and you can follow the issue here: Width and Lenght are set to 0 if skeleton is not visible on export · #335 · EsotericSoftware/spine-editor

Thanks Erikari!
I will try this solution.

Update:
Seems to work well so far - I'll update if the workaround fails at some point.
