AppGameKit Chat / Can't load Akeytsu animations by name?

So, today I was trying to some basic animation things, to see what AppGameKit can load and I came across an issue. AppGameKit can load Akeytsu animations if you play animation with "", but it cannot play an animation from the FBX by name. I've included a chicken model with a single "idle" animation I was working on to test: but, I wanted to make sure AppGameKit could load them. So, while it loads the model and animation just fine, it cannot play named animations? So, if I use PlayObjectAnimation with "" as the name, it plays the animation. if I try referencing the animation by name "idle" it says animation not found. (you might want to permanent scale chicken down to 0.01)

Am I doing something wrong? Or is this a quirk with AppGameKit? Akeytsu is a very popular indie animation package, so I'd love to be able to get this working.

Thanks!

So, I dug into this a little and solved the mystery for getting Akeytsu FBX files to work...

If this this: Str( GetObjectNumAnimations( mesh ) ) + " / " + GetObjectAnimationName( mesh, 1 )

It correctly reported the number of animations, BUT the interesting thing was in the name of the animation that was returned.

The name of the idle animation returned was: "AnimStack::idle" instead of just "idle", and once I put AnimStack::idle in the PlayObjectAnimation... it worked. It also worked with over animations.

So, that's how you get Akeytsu animations working with AppGameKit.

Further Caveats...

FBX animations do not export properly in HTML5 exports.

Thank you for sharing this information.
I have similar issues with animated files in general regarding the animation names

I've solved the HTML5 workaround; you have to export into ASCII FBX format with baked animation, and use AnimStack:: before the animation name.

ASCII + baked anims = best solution for both PC and HTML5 export.

Oh, so it actually works, somewhat. Been eying this program before. I should have bought it when it was on sale

Not just somewhat, if you export with ASCII format, baked animations, and use AnimStack::anim_name it works perfectly... at least for PC and HTML5. I never tried for iOS or Android though.

Hello LillyByte,

We noticed your message here and we investigated your problems.

It seems that the prefix "AnimStack ::" before the animation names (and other prefixes like "AnimLayer ::" before the layer names) is automatically added by the FBX SDK.

To check it out, we exported an animation from Maya and there were the same prefixes.

But you mentioned previous uses of the original name, what was the source of the export?

Regards,

Akeytsu Development Team

Thank you for the response and looking into it, but this isn't an Akeytsu issue at all. It's definitely a FBX loading quirk for AppGameKit that I just wanted to make sure people were aware of, that they had to include AnimStack:: prefix to get FBX animations to work with AppGameKit. That wasn't mentioned in the AppGameKit documentation from what I could see, so it took some fumbling to figure it out.

"AnimStack::" isn't added by AppGameKit, it sounds like the exporter added it on it's way through the FBX SDK. Playing animations with an empty string for the name will play the first available animation regardless of name.

I have Akeytsu although I haven't use it yet due to the lack of my free time. I believe this is is a very promising app since it is unique. I have always wanted a specified application to 3D skinning and animation since I use Silo3D which is a fantastic application for game modelling and I've never managed to got familiar with the UI of Blender3D

Akeytsu is amazing, I snapped it up the moment I saw it on Steam way back when.

I used to use Silo for modeling too; I loved it, but then I discovered Nvil. If you like Silo, you might love Nvil even more. Nvil is just as easy to use, but, with much more polygon modeling power than commercial packages like Maya, MODO, etc.

Me either.

That is why I went/stuck with Milkshape3D and FragMOTION. (back in FPSC classic)

I mainly use FragMOTION these days, now that I have gotten familiar with its UI.

It is low cost, powerful, and has a friendly UI so it is easy to learn to use for beginning modelers. (which is what I was when I started using it)

I still consider myself an amateur modeler and animator, but I can create, texture (UV mapping), and animate my own 3d models, so I am very happy with FragMOTION.

Thank you for the inside information on that Paul!
