Get the Sprite in the Spine Graphic

Hello Guys,
How can i get the sprite in the Spine? Like I have a animal with 3 part like head, body, foot. I want to get the sprite of the head of the animal to show?

thuanisme1710 I'm afraid I could not quite understand your question. Is your question about the operation on the Spine editor? Or do you mean that you want to get the head sprite at runtime? If it is the latter case, could you tell us what Spine runtime you are using?

Misaki Like when i click the Dog Object. It will show 3 part of the dog in each sprite (head sprite, Body sprite, Foot sprite). How can i get the Head sprite in the Spine? Can spine do that?

thuanisme1710 I am afraid I am repeating almost the same question, but I still don't understand what you mean by that.

Like when i click the Dog Object.

Where are you supposed to click on the Dog object? On the Spine editor or at runtime?

How can i get the Head sprite in the Spine?

Do you mean "get" here in the sense of getting the image file at runtime via code?
I suspect you may be confusing the term - Spine is the name of the tool, but the animatable characters and objects you can create in Spine are called "skeletons". Am I correct in understanding that what you want to do is to get the head image from a skeleton?

The first picture is the Spine Graphic. And when i click that Object, i want to show three part sprite of the head, body, wing like the Pic 2. Can the spine help i get the sprite of each part?

It depends on the runtime you are using, and if you've customized attachment loading or rendering. Also note at runtime the attachment images are not usually separate images. They are in a texture with many attachment images packed into it.

You can see spine-unity here:
https://github.com/EsotericSoftware/spine-runtimes/blob/4.1/spine-unity/Assets/Spine/Runtime/spine-unity/Asset%20Types/SpineAtlasAsset.cs#L275

An attachment has a rendererObject. The attachment rendererObject is usually an atlas page, but can be customized via an AttachmentLoader.

An atlas page also has a rendererObject. What it is depends on what game toolkit you are using and how rendering is done. For Unity that gets set to a material.

You would need to get the attachment for each slot, look at the rendererObject, cast it to an atlas page, look at the page's rendererObject, cast it to a Unity material, and then use the Unity API to get more information from there.

The attachment also has the UVs that describe the position within the atlas page texture that make up the region. Drawing using that isn't super easy. It may be doable for regions, but for meshes it's harder.

An alternative to all of this is to create a skeleton for each piece you want to show (or reuse a single skeleton), then hide all the attachments except for one. Use the bounds of the skeleton to draw the one attachment in the right place.
