Pixi Spine problem

[pavelgramen]

Hi, encountered a problem displaying spine animations in PIXI - texture issues

everything works in starling

thanks for any help

Hi!

Looks like premultiplied alpha issue again. Please publish the demo with the version of pixijs and pixi-spine you are using.

Thanks for the quick response.

"pixi-spine": "^2.1.7",

"pixi.js": "^5.2.1"

In case you use premultiplied alpha in png textures, specify it for pixi: dig out which baseTexture it uses and specify "mySpineResource.spineAtlas.pages[0].baseTexture.pmaMode = PIXI.ALPHA_MODES.PMA"

We added this feature to pixi but didn't propagate it to pixi-spine.

PMA did not help

isPowerOfTwo: false

mipmap: 1

pmaMode: 2

resolution: 1

Then I dont know what can be wrong there. Please send me minimal demo, whether its a zip or jsfiddle

OK, confirmed, it works in latest spine-ts but not in pixi-spine.

Maybe I can look at it in weekend, maybe not.

There's an issue https://github.com/pixijs/pixi-spine/issues/318 with skins, maybe the same problem appears in your case. Yes, I couldn't fix it since november, it requires a total rewrite of "Spine.js" "update" function.

If you want to investigate yourself, clone https://github.com/EsotericSoftware/spine-runtimes/tree/3.8/spine-ts and put your demo in webgl/examples. They dont have JSON by default there, so I had to modify loadSkeleton method a bit:

// .. load

function init () {
   //...
	assetManager.loadText("assets/Down.json");
	assetManager.loadTextureAtlas("assets/Down.atlas");
    //...
}

function load() { 

  //...
    skeletons["Down"] = loadSkeleton("Down", "run", false, undefined, true);
}

function loadSkeleton (name, initialAnimation, premultipliedAlpha, skin, isJson) {
    //...

	var skeletonBinary = new spine.SkeletonBinary(atlasLoader);
	var skeletonJson = new spine.SkeletonJson(atlasLoader);

	var skeletonData = isJson ?  skeletonJson.readSkeletonData(assetManager.get("assets/" + name + ".json"))
					: skeletonBinary.readSkeletonData(assetManager.get("assets/" + name + ".skel"));
    //...
}

From another point of view it looks like a texture rotation problem... I'll ask one more person to look at it. @eXponeta you alive?

[ivan.popelyshev]

Do you use telegram? t.me/hackerham 

[pavelgramen]

I’m alive, I don’t use a telegram, maybe Skype? pasha_gr

[eXponeta]

So, maybe telegram ?

Because Russian PIXI community alive in it.

[pavelgramen]

OK, we had a problem with rotate=180 in atlases. Fixed. Use pixi-spine 2.1.8
