Texture Unpacker

BinaryCats

this is great!

a long requested feature finally made it to spine.

As I understand it, the texturepacker can be/ is a standalone program which will produce the same results. As it is libgdx's texture packer. ( I could be wrong in all of this. it was a while ago)

Is this true with the texture-unpacker?

i.e. would a user be able to unpack the source images, edit them, and repack, for the game to use, without needing spine?

Yes, it is the same as libgdx's unpacker. Spine doesn't expose the unpacker on the CLI, but we'll add that. Until then, you could grab gdx-tools from libgdx and run the packer. Or here, for the lazy:
http://n4te.com/x/1130-unpacker.jar
Run it like:

java -jar unpacker.jar your.atlas imageDir outputDir

Thanks 🙂

This opens up a nice set of possibilities for the users of the games to add up their own customizations 😃 (somethinng like in steam workshops)

For mods, it'd be easier to simply paint on (a copy of) the atlas pages instead of unpacking, painting then repacking.

but assuming you haven't used meshes, you don't know what space you have to play with. Say if you want to make the head bigger, you don't know how big it can be without overlapping with another body part texture

The same would apply with individual images and repacking.

Nate

I believe bcats is saying that with individual images you can more easily see the space you can paint in. You don't have more space, but you can see it more easily and you can't paint outside the region.

If you allow editing of atlas pages in say a Unity game, you can use the atlas region information to display and make modifieable only the part of an atlas page a region covers. If you want unpacking at runtime, you'll have to port the Java-based unpacker to your favorite language, including cutting up the image.

correct

I just meant if the user wanted to fish the texture out of the data, they could edit it easily with the unpacker 🙂

We are all correct! :party:

But bcats is the most correct.
