关于SkeletonAnimation同步到SkeletonGraphic上

Berain

我的项目使用了Spine来制作Player，现在正在制作装备系统，由于装备图片的资源量较多，用spine的skin管理起来不是特别方便，于是我想直接用unity中的sprite来替换进去。我已经完成了场景中Player（SkeletonAnimation）的装备外观替换，基本都是使用函数“ReplaceSlotWithSprite”来替换Skeleton中的Attachment（下面有详细的核心代码）。

需求：现在我想在装备界面中显示UI-Player（SkeletonGraphic），并且在每次换装时都能同步改变Player和UI-Player的装备外观，为此我需要在换装后将Player（SkeletonAnimation）的各种信息同步给UI-Player（SkeletonGraphic），我询问chatGPT获得代码方案后，执行的效果一直存在问题，甚至毫无效果，我已经调试了几天毫无进展，Spine官方是我最后的希望了，我想知道如何将SkeletonAnimation的所有东西复制到SkeletonGraphic上（它们使用了同一个SkeletonData）。

public bool ReplaceSlotWithSprite(EquipSlot slot, Sprite sprite, string preferTemplateAttachmentName = null) {
var skeleton = GetSkeleton();
if (skeleton == null || sprite == null) return false;
int slotIndex = FindSlotIndexByEnum(slot);
if (slotIndex < 0) return false;
// 若该槽有 CustomSlotMaterials 覆盖，先移除，让 remap 后的专用材质生效 RemoveCustomMaterialForSlot(slot);
var template = FindBestTemplateAttachment(slotIndex, preferTemplateAttachmentName);
if (template == null) { Debug.LogError($"缺少模板附件：{slot} / prefer={preferTemplateAttachmentName}");
return false;
}
var remapped = RemapFromTemplateAttachment(slot, template, sprite);
if (remapped == null) return false;
skeleton.Slots.Items[slotIndex].Attachment = remapped;
ApplyAndRefresh();
return true;
}

Attachment RemapFromTemplateAttachment(EquipSlot slot, Attachment template, Sprite sprite)
{
if (template == null || sprite == null) return null;
var skeleton = GetSkeleton();
if (skeleton == null) return null;
var tex = sprite.texture;
var mat = GetMaterialForSlotTexture(slot, tex);
if (mat == null) return null;
if (template is RegionAttachment ra) return ra.GetRemappedClone(sprite, mat, false, true);
if (template is MeshAttachment ma) return ma.GetRemappedClone(sprite, mat, false, true);
Debug.LogWarning($"不支持的模板类型：{template.GetType().Name}"); return null; }

Attachment FindBestTemplateAttachment(int slotIndex, string preferAttachmentName = null) {
var skeleton = GetSkeleton();
if (skeleton == null) return null;
var sData = skeleton.Data;
var defaultSkin = sData.FindSkin(defaultSkinName) ?? sData.DefaultSkin;
if (!string.IsNullOrEmpty(preferAttachmentName) && defaultSkin != null){
var at = defaultSkin.GetAttachment(slotIndex, preferAttachmentName);
if (at != null) { if (logVerbose) Debug.Log($"模板：指定名 {preferAttachmentName}");
return at; }
}
var slotName = skeleton.Slots.Items[slotIndex].Data.Name;
if (defaultSkin != null) { var at2 = defaultSkin.GetAttachment(slotIndex, slotName);
if (at2 != null) { if (logVerbose) Debug.Log($"模板：默认皮肤同名槽 {slotName}"); return at2; } }
if (defaultSkin != null) {
var entries = new List<Skin.SkinEntry>();
defaultSkin.GetAttachments(slotIndex, entries);
foreach (var e in entries)
if (e.Attachment != null) { if (logVerbose) Debug.Log($"模板：默认皮肤任意 {e.Name}");
return e.Attachment; } }
var current = skeleton.Slots.Items[slotIndex].Attachment;
if (current != null) { if (logVerbose) Debug.Log("模板：当前槽附件兜底"); return current; }

@Berain Sorry to hear you're having troubles. Which exact version of the spine-unity runtime (name of the unitypackage, also listed in Assets/Spine/version.txt or in the Package Manager window) are you using?

I'm afraid I don't understand from the posting above what actual issue you are facing with SkeletonGraphic. In general if you issue the same calls on SkeletonGraphic.Skeleton as on SkeletonAnimation.Skeleton you should see the same results.

In general please always describe or show (with screenshots) what your expected result is and what you are getting instead.

Regarding code formatting, please note you can surround your code section with triple-backticks '```' or [code] [/code] to have it properly formatted:

我用的spine-unity runtime是4.2版本，spine是4.2.43版本。

当替换一个头部装备时：

再换上武器、盾牌和披风（背部挂件）后：

Berain 我用的spine-unity runtime是4.2版本，spine是4.2.43版本。

Please always share the exact (full) spine-unity runtime version, not only 4.2. The exact version number is the name of the unitypackage including the date (e.g. "spine-unity-4.2-2025-09-26"), also listed in Assets/Spine/version.txt or show the exact version from the Package Manager, e.g. 4.2.109.

Thanks for sharing additional screenshots.
What are your settings in the Advanced foldout section of the SkeletonGraphic component? Do you have Multiple CanvasRenderers enabled?

Please note that you've shared two complete classes here, one with 750 lines of code and one with 215 lines. We can't debug your code in our head, you would need to boil the problem down to the minimum of code that still causes your issue to happen.
