LeinadNoscaj We can help you identify why your code isn't working as you're intending. Could you provide us with an example of what you've tried so far?

stuff like


 success: function (player) {
        player.setAnimation("run", true);
             delay: 5
             player.addanimation("walk",true)
   },
   error: function (player, reason) {
      alert(reason);
   }

Luke

LeinadNoscaj In your call to setAnimation(), you didn't provide it with a track index that you want the animation to play on. You can call setAnimation() properly by writing code like player.setAnimation(0, "run", false);.

It looks like you're missing parameters in your call to addAnimation(). Here's the addAnimation function from AnimationState.ts:
EsotericSoftware/spine-runtimesblob/4.2/spine-ts/spine-core/src/AnimationState.ts#L563

The delay number is a parameter you pass to the function, like so: player.addAnimation(0, "walk", false, 5);.

I would encourage you to check out the spine-ts runtime from our Github page and read through the examples.

Luke
how do I use the addAnimation function?
Do I have to paste the file into my HTML doc?

Nate

We are happy to help you as much as we can, but you'll need to learn coding, read our documentation, and go through the example projects. Your problem appears to be that you are jumping ahead without enough understanding. We cannot help you learn everything from scratch. Start over with the simplest possible setup (probably one of our examples), get that to work, understand it, and then make it more complex from there. Don't skip any steps.

Have you tried using AI? ChatGPT or DeepSeek can be a great resource. You can ask it Spine questions and usually it gives great answers.

LeinadNoscaj

Nate I've been trying with Google gemini
Unfortunately its been writing stuff even less correct then me

Nate

Aye, Gemini is not very good. I prefer ChatGPT. If you don't want to pay the $20/month, DeepSeek can be just as good. You might also try Claude.

LeinadNoscaj

Nate is Microsoft copilot any good?

Nate

I don't use it, but probably. Under the covers it is ChatGPT.

LeinadNoscaj

hey I know its been a while but I finally found out how the JSON was encoded
it was done using compress-json (beenotung/compress-json)
is there a way to plug the compress reverser into the spine runtime?

Nate

You would decompress it with that, giving you regular JSON, which you'd give to Spine as normal.

LeinadNoscaj

after a bunch of circulatory discussions with AI, I finally came up with the start of a solution

I'm getting the JSON file decompressed, then base64 encoded. I can't for the life of me figure out how that works tho

LeinadNoscaj

just realized my previous reply may be confusing, the part I don't understand is the RawDataURIs section. I'm not really sure where to put my variable containing the BASE64 for the JSON, and the same goes for the Atlas

Davide

LeinadNoscaj

You have to place it in the player config. It's pretty clear in the documentation.

LeinadNoscaj

Davide right, sorry I probably should've been more specific.

      skeleton: "raptor-pro.json",
      atlas: "raptor-pma.atlas",
      rawDataURIs: {
         "raptor-pro.json": "data:application/json;base64,<base64 encoded raptor-pro.json>",
         "raptor-pma.atlas": "data:application/octet-stream;base64,<base64 encoded raptor-pma.atlas>",
         "raptor-pma.png": "data:image/png;base64,<base64 encoded raptor-pma.png>"
      }
}

where in this example would I put the BASE64 encoded json file, and would I need to append the .JSON onto the end of it

Davide

LeinadNoscaj

<base64 encoded raptor-pro.json>

How do I layer 2 animations on top of each other?
For what I'm trying to create a preview of, there's one animation that controls the skeleton, another that controls the special effects. How do I combine the 2?

Nate

See advanced playback:
https://en.esotericsoftware.com/spine-player#Advanced-playback
And AnimationState:
https://esotericsoftware.com/spine-applying-animations#AnimationState-API

LeinadNoscaj

I'm having trouble with the success callback. The code is working fine besides the animation part, I can't get it to work.

                    new spine.SpinePlayer("player-container", {
                        skeleton: `${filename}.json`,
                        atlas: `${filename}.atlas`,
                        rawDataURIs: {
                            [`${filename}.json`]: jsonDataUri,
                            [`${filename}.atlas`]: atlasDataUri,
                            [pngFilenameFromAtlas]: pngDataUri
                        },
                      alpha: true, // Enable player translucency
                      backgroundColor: "#00000000", // Background is fully transparent
	              premultipliedAlpha: false,
                      skin: filename,
		      success: function (player) {
                             player.setAnimation("run", true);
                         },
                      error: function (player, reason) {
                             alert(reason);
   }
});

I keep getting this error, and I'm not sure where its coming from

Uncaught SyntaxError: Missing catch or finally after try

Nate

The error is odd, as if you had try { ... } with no finally. Does it tell you where the error occurs? If you can post a link to these files on your webserver, that would help.

The JavaScript looks fine. Do you have a run animation in your skeleton?
