Can't switch Skin in Spine-Cocos2d-x

shrimps

My artist use SpineEditor for Skin.
In my program, I used follow codes:

    auto sp1 = spine::SkeletonAnimation::createWithFile("goblins.json", "goblins.atlas");
    sp1->setPosition(100, 100);
    sp1->setSkin("gobilin");
    sp1->addAnimation(0, "walk", true);
    layer->addChild(sp1);

but it can't switch Skin in Spine-Cocos2d-x.

And I use SpineEditor's demo, it look like too.

Here is my test resource.

try...

auto sp1 = spine::SkeletonAnimation::createWithFile("goblins.json", "goblins.atlas");
sp1->setPosition(100, 100);
sp1->setSkin("gobilin");
sp1->setSlotsToSetupPose(); // this should make skin change
sp1->addAnimation(0, "walk", true);
layer->addChild(sp1);

It's OK!
thx.

But, I modify Skin.c, the result is same to call setSlotsToSetupPose().

Original Code

void spSkin_attachAll (const spSkin* self, spSkeleton* skeleton, const spSkin* oldSkin) {
	const _Entry *entry = SUB_CAST(_spSkin, oldSkin)->entries;
	while (entry) {
		spSlot *slot = skeleton->slots[entry->slotIndex];
		if (slot->attachment != entry->attachment) {
			spAttachment *attachment = spSkin_getAttachment(self, entry->slotIndex, entry->name);
			if (attachment) spSlot_setAttachment(slot, attachment);
		}
		entry = entry->next;
	}
}

Modified Code

void spSkin_attachAll (const spSkin* self, spSkeleton* skeleton, const spSkin* oldSkin) {
	const _Entry *entry = SUB_CAST(_spSkin, oldSkin)->entries;
	while (entry) {
		spSlot *slot = skeleton->slots[entry->slotIndex];
		spAttachment *attachment = spSkin_getAttachment(self, entry->slotIndex, entry->name);
		if (attachment) spSlot_setAttachment(slot, attachment);
		entry = entry->next;
	}
}

You may want to change skins without setting the slots to the setup pose.

Faced the same issue... Sorry, but it is not intuitive and very weird. When i change skins in editor, i expect that when i use setSkin(), it will behave the same way as it does in editor. Is calling setSlotsToSetupPose() after setSkin() behaves the same way as switching skins implemented in editor?

Nate

The editor isn't the same as using the runtimes. When you set a skin you may not want to change all of the currently attached attachments. Remember, not all attached attachments have to come from a skin. Maybe in your runtime usage you set some attachments from the skin and some manually.

I do agree it's a nasty gotcha in the API. I'd like setSkin to have a boolean so you are forced to decide which behavior you want.
