PixiJS doesn't support Spine Mesh feature

[englercj]

Cross posting GoodBoyDigital/pixi.js#1349.

@JaredSartin @rpurushotma @Partysun

I will be happy to help , especially if you show me what are you doing with Dart. I want to port pixi v3 to dart + spine plugin too!

[JaredSartin]

Ideally we could just use this as the mesh/skinned mesh renderer for spine animations - not need dart1

I am not using dart for the project at the moment. I was using an example project that actually rendered meshes via dart only because Pixi couldn't :( :(

[ivanpopelyshev]

@JaredSartin Can you check if the problem is there in latest 2.x version? I remember we fixed something in FFD

[ivanpopelyshev]

Right there: https://github.com/GoodBoyDigital/pixi.js/commit/6d2da3a70b1b50f99ded79005d515ac5f2fbe8fd we found that FfdTimeline and IkConstraints derped while calculating duration :)

[JaredSartin]

May be fixed. I have yet to check. I think my project ended a couple days prior to that commit. Thanks for pointing that out.

Any update on this?

[ivanpopelyshev]

@Shadowstep33 Last time I checked, Mesh was working.

[Shadowstep33]

My meshes throw some WebGL warnings and don't appear on screen:

WebGL: INVALID_VALUE: bufferData: no data

and

[.WebGLRenderingContext-06F1C470]GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 0

EDIT: I answered my own problem unknowingly. The problem seems to lie in using WebGL renderer. Switched to canvas and it works.

[ivanpopelyshev]

@Shadowstep33 Does it work with CanvasRenderer?

UPD. oh. Ok. now we have problem in WebGL renderer...

[Shadowstep33]

Yes it does. Can we not use meshes in WebGL?

[ivanpopelyshev]

Is that problem exists for every mesh or just some of them?

[Shadowstep33]

I haven't gotten that deep into utilizing spine, but of all the Spine files i've been sent by my coworkers, all of the ones with a mesh do not work.

[Shadowstep33]

Keep in mind, that's all the layers with a mesh. The other layers will still show up and animate, so the overall Spine object is still there and trying to draw

[ivanpopelyshev]

Ok, I have some Meshes, I'll test it :)

@Shadowstep33 can you wait a few hours?

[Shadowstep33]

Indeed I can, appreciate the help

[Shadowstep33]

If this helps at all, I get this bug in IE using WebGLRenderer

WEBGL11128: INVALID_VALUE: bufferData: bufferData must be passed a size or an array. Null and undefined are not valid File: pixi.js, Line: 26035, Column: 5

I submited a pull Request to fixed this issue & bit more https://github.com/pixijs/pixi-spine/pull/30

Mesh, SkinnedMesh & blending mode are now supported,

But you need another fix from pixi, I also made a pull Request for that https://github.com/GoodBoyDigital/pixi.js/pull/1784

With those 2 changes everything run perfectly as in Spine

[ivanpopelyshev]

That patch contains fixes about blendModes and getFrameCount. I believe you. Merged.

@Shadowstep33 please test it

[Shadowstep33]

Did you merge to pixi spine as well? Github only says you merged to pixi.js, but that's on the pixi-spine ticket. I downloaded both pixi.js and pixi-spine.js from the master branches, but no dice; the mesh still isn't appearing.

[simonTadram]

my change didn`t get merged yet in pixi, but it is in pixi-spine

In my previous message I pointed the pull request that tyou would need to get as well for pixi https://github.com/GoodBoyDigital/pixi.js/pull/1784

or get my fork at https://github.com/simonTadram/pixi.js (pixi dev branch up to date + my change)

And It seems I forgot to rebuild it. Uploading new binaries.

[ivanpopelyshev]

@Shadowstep33 please try simonTandram's pixi.js: https://www.dropbox.com/s/31za9d5nsa8p8e5/pixi.js?dl=0

and latest pixi-spine.js https://github.com/pixijs/pixi-spine/blob/master/bin/pixi-spine.js

[Shadowstep33]

Mesh.js: 19: Uncaught TypeError: Resource.setExtensionXhrType is not a function

That error is thrown when I try to load with both of those files

[ivanpopelyshev]

@Shadowstep33 !@#$ I forgot to npm install :) Wait 1 minute, I'll update pixi.js in my dropbox

[Shadowstep33]

hahahah all good man, let me know when it's built :P

[ivanpopelyshev]

Done. Lets try again!

[Shadowstep33]

Does it update immediately on github? It still says edited 7 hours ago and is throwing the same error

[ivanpopelyshev]

I updated pixi.js built in my dropbox: https://www.dropbox.com/s/31za9d5nsa8p8e5/pixi.js?dl=0 I built version with simon's patch, but I forgot to update some npm modules.

[Shadowstep33]

Yay works perfectly! Thanks @ivanpopelyshev and @simonTadram !

[Shadowstep33]

Oh actually, unfortunately an older pixi bug is back it appears! That sprites w/o interactive block sprites with interactive.

The issue is linked below https://github.com/GoodBoyDigital/pixi.js/issues/1725

[englercj]

Just released v3.0.5 which includes the PR from @simonTadram.

https://github.com/GoodBoyDigital/pixi.js/releases/tag/v3.0.5

[Shadowstep33]

@englercj thanks! I'm going to wait for the sprite interaction fix before updating from the version I am currently using.

[ivanpopelyshev]

@englercj so we can close it , right?

[englercj]

Go for it
