Can only change to an animation with a higher index about sceneform-android

[ThomasGorisse]

Hi,

Can you provide your .glb and .blend if made from it?

[Knotworking]

Yes of course cat.zip

You'll notice in the blender file that all of the actions have been doubled. I was experiencing strange behaviour before I stumbled upon this ugly hack, but it seems to work. I was checking my .glb files with https://gltf-viewer.donmccurdy.com/ , and both in this webtool and in sceneform the actions aren't doubled and seem to play correctly individually.

[ThomasGorisse]

Ok, I figured out what was happening.

I fixed your issue and will soon commit it.

I can confirm that you have to call the animator?.cancel() since the auto cancel will work only if you start a new ModelAnimator with the same index.

Thanks for your feedback.

[ThomasGorisse]

Can you make the test with the master version?

[Knotworking]

Yes I can confirm the latest master version works 👍

As a side note, I tried using jitpack to get the master branch dependency with:
implementation 'com.github.thomasgorisse:sceneform-android-sdk:master-SNAPSHOT'

However I couldn't get it to work, so just built it locally.

Thanks for looking into this issue 👏

@ThomasGorisse should it be resolved in 1.20.2?

I have the same issue with the example [sample-ar-model-viewer], also I'm unable to switch between animations on my project.

I can provide You with a sample project with .glb file and code to test it. I can record the video for You if You need it. Thank you

[ThomasGorisse]

Did you try to test your model on a Gltf Viewer?
Are you animations listed there?

[kustraslawomir]

Yes :)

Also getAnimationNames() return [Farewell, Greeting, Idle, No, Pointing, Talking, Yes]

You can Track the queue I'm running the animations. Incrementing works just fine, but I can't go back for example from Pointing to Greeting.

 private fun displayDebugAnimationList(arCharacter: RenderableInstance) {
        val availableAnimations: List<String> =
            arCharacter.animationNames

        Log.d("Animations", availableAnimations.toString())
        debugButton.setOnClickListener {
            val adapter = ArrayAdapter<String>(
                requireContext(),
                android.R.layout.simple_spinner_dropdown_item,
                availableAnimations
            )
            AlertDialog.Builder(requireContext())
                .setSingleChoiceItems(adapter, 0) { dialogInterface, index ->
                    Toast.makeText(
                        requireContext(),
                        "set animation: ${availableAnimations[index]} index: $index from: ${availableAnimations.toString()}",
                        Toast.LENGTH_LONG
                    ).show()
                    arCharacter.animate(index).start() // same with animate(availableAnimations[index])
                    dialogInterface?.cancel()
                }
                .create()
                .show()
        }
    }

Also, I'm on:

git pull origin master
From https://github.com/SceneView/sceneform-android
 * branch            master     -> FETCH_HEAD
Already up to date.

[kustraslawomir]

Ok @ThomasGorisse I think It's because I didn't call .cancel() on ObjectAnimator...

objectAnimator?.cancel()
objectAnimator = ModelAnimator.ofAnimation(arCharacter, index).apply {
       start()
}

With this change, it's working and I can go to the previous animation. Thanks again mate! <3

[ThomasGorisse]

Great!
I'm curious. Could you provide a screen record just to see what it looks like?

[kustraslawomir]

Now I can switch from 0->1->2->1->0 etc
