How to include origin value in export atlas region?

brianlin1992

Hi, I was using Editor version 4.0.46-beta to export frame by frame atlas with origin data. The feature was officially included in 4.0.46-beta.

When exporting an image sequence and packing, the world origin is written to the atlas file for each frame.

Example:

Chef_chibi-Idle_02 bounds:851,240,167,222 origin:118,4 Chef_chibi-Idle_03 bounds:851,18,167,222 origin:118,4

I has worked back on this project but the latest versions don't have this feature (it has offset instead but offset value doesn't define the correct position of orgin).
And I also cannot roll back editor to 4.0.46-beta.

Hope I can get some help, it's pretty urgent. Thank you a lot in advanced.

Make sure you uncheck Legacy output. Which image export are you doing? I see it working in 4.1.24, eg open spineboy, export PNG, run, check Pack, atlas has origin:

run.png
size:1830,1946
filter:Linear,Linear
pma:true
spineboy-pro-run_00
bounds:1167,1455,489,638
offsets:136,3,630,682
rotate:90
origin:286,7
spineboy-pro-run_01
bounds:557,487,378,631
offsets:159,8,630,682
rotate:90
origin:286,7
...

The offsets are something else, when whitespace stripping is used the offsets are how much to shift the region so it can be drawn as if whitespace was not stripped.

Nate Hi Nate, sorry a lot for requesting help again. I found that this version origin is pretty weird. The origin value is consistent throughout all sprites of one animation. It makes the character jiggling abit.

I suspect that the origin is only calculated once and apply for all the region of one animation.
Could you check this part?

Thank you a lot. This version works great!

Nate

Are you whitespace stripping in your atlas? If so, please try without whitespace stripping. If that works it means you need to use offsets when drawing the regions.

Nate After I subtract the offset value, it works great now. Thank you 😃
