Hi there
Does anybody know how to set up and export an animated character with a bone rig to AppGameKit?
What is the best format to export to? And what export options should be ticked?

I have successfully imported a character from Mixamo fuse into Blender with animation. I have exported it both as a .dae (collada) file and as a .fxb file.
The model comes up in agk. But I can't seem to animate it. GetObjectAnimationName() returns empty.

There is a lot of factors in this question, but if anybody have any experience with this....please throw them at me

Tim

EDIT: attached my blender test file

I am not sure if the .fbx or .dae formats export animation data in Blender you would need to do some research.
I am not an expert with Blender but I did export your model from Blender in the .x format and it contains animation.
I tested it in AppGameKit and the animation works. FYI your model contains 48 bones I believe there is a 40 bone limit in AGK
so you may want to reduce the number of bones. I have attached the .x file. Hope this helps.
The coffee is lovely dark and deep,and I have code to write before I sleep.

I would really like to know how to do this as well.

For that oldman file, the .x version you posted looks like the attached image. It does play the animation.

The .blend file loads into Blender and plays the animation.

A .obj file exported from Blender loads into AGK2, but does not animate.

The .blend file seems to load into AGK2, but I cannot see anything. All .blend files that I save in the current Blender version have this behavior. I have been able to load and see some .blend files that I believe were made with earlier version of Blender.

Is there some trick to loading in current .blend files? Or getting .x files exported from Blender to look right?

Hi

I think the "Collada" import doesn't works in AppGameKit (with animation).

The .x is ok, but the animation is always named "global". All animations must be in one action, not several.
And we have to choose the animation with the frame we want (ex : walk -> frame 1-20, die -> 21-30, hit -> 3 -40...).

Blendman, have you been able to load a Blender file exported to .x file with children (animations) into AGK2?

Any .x file I export from Blender doesn't load correctly with the "with children" command.

If you can, would you mind posting a .x file exported from Blender, with any animation, that you have been able to load into AGK2?

I am trying to find out if it's a problem with AGK2, or maybe a problem with my computer.

Rich Dersheimer : I have made a very simple animation (with blender 2.76) to test the export .x from blender to agk2 and it works fine.
AGK2 load the model and its animation.
Here is my test file :
http://www.dracaena-studio.com/images/games/dev/bug/animation.x

I haven't found how to export the oldman.blend in this thread. it doesn't work for me, with the 2.76, in the .x format.

Thanks for posting that, I will check it right away!

EDIT: Rats! That link just opens a web page with the text on it. I'll copy and paste though.

EDIT 2: The very first time I loaded your test object, some of the face vanished. Every time after that it looks fine, the animation plays. Is there some special settings that you had to use to get the .x export out of Blender to work correctly?

For the export, i have checked : exports meshes, normals, uv coordinnates, export skin weights, amatures bones, rest position, animation, animation as animationset.

For the link, I have attached the file, I don't know why it open a web page with text ^^.

Thanks, Blendman! Using those settings, I have just exported my first .x file from Blender into AGK2 that actually shows up and animates! Woot!

Hi there and thanks Blendman and Stab in the dark.

Exporting it to x format works for me. I don´t know why .dae or .fbx does not show animation....
As Stab in the Dark pointed out - the mixamo fuse characters has over 40 bones so I guess thats why the hands get distorted. I reduced the number of bones down to 42 by only using 2 bones for the hands. So now only one hand is distorted. I think Mixamo fuse is a great way to make som placeholder prototype animations, but to use them you have to either remove the hand bones (then you're down to 25 bones - but you get stiff hands) or remove some bones manually in blender (but then you f**k up the mixamo animations)...

Thanks for the help....I´m a huge step closer thanks to you guys...and I´ll post any solution to the bone limitation for Mixamo fuse - if I find any.

Attached is the exported .x model with 42 bones - but agk reduce them to 40 and thats why (I think) one hand is distorted.
Also - exporting to .x format rotates the model - so its upside down.

EDIT: attached another model: woman.x with only 25 bones (stiff hands). Works fine. No distortion. So I´m pretty sure now that the number of bones is why the oldman.x model is distorted.

@ TimShark : how do you use your .dae in agk ?
in PlayObjectAnimation(), the startTime and EndTime is in second, not in frame. I did this error when I tried to open a .dae animation

Blendman, yes, the .dae file shows up but it only plays the current animation set during export. I cannot access the other animations "actions" by name as I can with .x.
My model includes 10 different animations.

Tim, I think you should use the StartTime and StartEnd.
It's possible that blender doesn't export the animation set name, so it's better to use the frame for your animation.

For example, in blender, you should have :
Total frame (for 10 animation of 20 frame) : 200 frames
- frame 0 to 20 : walk
- frame 21 to 40 : run
- frame 41 to 60 : die
and so...

In AppGameKit, you can use :
walk -> framend = 20 /200 or 0.1 -> PlayObjectAnimation(objid,"",0,0.1,1,0)
Run -> framend = 40 /200 or 0.2 -> PlayObjectAnimation(objid,"",21/200,0.2,1,0)
die -> framend = 60 /200 or 0.3 -> PlayObjectAnimation(objid,"",41/200,0.3,1,0)
and so

I don't know if it works, but I think that it does .
Tell me if it's ok for you, I'm curious to know if this technic works ^^.

Blendman, I read your post inside the agk snippets thread and learned that you need to have all your animation on the same timeline, instead of separate actions when you export to .dae.
That´s my problem - else .dae works much better with agk
I have to stack my animations different now - some work to do.
Thanks for all the help

Please can someone send me a .dae file with multiple animations, each with a different name, as this is something thought the Asset Import Library would support, and I want to check out what is happening.

Paul, I´ve searched around and I found this:
http://gamedev.stackexchange.com/questions/43221/blender-multiple-animations-and-collada-export

Where the answer is :"The Collada exporter in blender does not support what Collada calls "animation clips", so only the current animation will be exported."
The answer is from 2012 though.
Anyway - here is my test file. Both in blender and the exported collada (.dae) file.
Maybe someone else has a working .dae file with "animation clips"

Hi Paul

I use blender to export my animations and 3D models, and unfortunaltely, Blender doesn't export the animation names, I don't know why.

But here is a file (dae) with multiples animations (but I guess with no names), an AppGameKit file and the blend file.
http://www.dracaena-studio.com/images/games/dev/AGK_Animation_dae.zip

In the AppGameKit file, you will see that I use the animations Frames to set the animations (attack/die/wait).
I hope this will help you .

Paul, since agk uses the "open assets import Library" - why does it not show blend files? Could it be that the importer is not updated to blender 2.7xx?
