Animation system of the Blender Game Engine

@Porteries Tristan (panzergame) told me that this issue was fixed in UPBGE, in this commit: https://github.com/UPBGE/blender/commit/2b3405a360063e4b050105b3225e86313df693e8?diff=split

More than a week without reply. Due to the policy of the tracker archiving for until required info/data are provided.

Here is a clear example using blend file from this report, turning off and on one thread of my CPU, using:
@Porteries Tristan (panzergame) hi, mate. What happened with this bug? I also found in last Blender version.

Please add a blend-file that demonstrates this issue.

Resigning as reviewer, as I don't have time for BGE work any more.

Anyone make any progress on this? This still appears to be an issue on 2.78 (3c04373), and I'm fairly surprised that animation layers have remained broken for this long.

This type of animation is not not supported by the game engine.
Unfortunately I don't have time any more to work on BGE issues :/

Recently, I've created a VirtualBox with the same Ubuntu-Mate 14.04 x64 and copied some files. It's a almost clean installation... and it occurred to me to test this file with this installation. Beyond that the 3D acceleration is not good, I could open Blender and run the Game Engine: the animations runs correctly. So... it seems that the problem is in my system, but I don't know why.

Also, I tried to use KX_ACTION_BLEND_ADD with intentions of not affecting other layers/bones... with no success.
I'm uploading a new file.

I "discovered" this bug again... now, I have a file. @Mitchell Stokes (moguri) says in #gameblender "I could see blendin behaving strangely with layers. =/"

When I just finished writing the report, I realized that I reported the same issue 5 years ago. Because of this, I forgot to say that when I did this file, I was using the new depsgraph (*). And yes, as I said in the report (and you deducted), with new depsgraph, this configuration does work...
I say that because i know how current dependency graph and pose solver works, apparently.

@Sergey Sharybin (sergey), why do you say that we can't drive something inside of the same armature? The file I uploaded here does not work in BGE, but it does in Blender (and shows no error messages).
Those behave in a similar way.

@Sergey Sharybin (sergey), are you talking about Blender or the Game Engine?
You can not use a bone to drive something inside of the same armature, it's unsupported by the current dependency graph. We're working on solving limitations like that in a new system.

Maybe this is an oooold known system limitation... that I reported in 2010 (T22850)?

Thanks for testing it, @Angus Hollands (agoose77).
In your test file (Win10 x64, Blender 2.77a) the animation plays, if not slightly jerkily.

This bug is still in 2.77.
