%%%I have a rigged character in one file. I link it as a group to another, add a proxy for the armature, and animate it. How should I get the action to play in the bge?

My first attempt was to add an action actuator to the proxy object, but it doesn't do anything. That's what this bug report is about: should it do something?

In the end, I have decided to go with dfelinto's method: have the action actuator on the original armature object in the library, and set which action to play with a message. Both techniques are illustrated in the attached files:

character.blend is the library file, containing the mesh and armature. There are two groups: G_ok and G_bug; G_bug has no logic attached to it, while G_ok uses a message sensor and a short script to play the action.
game.blend uses the library file, pulling in G_ok and G_bug as groups. A proxy armature is made for each group; these share an action, "proxyAction". Both objects animate in the 3D view, but only G_ok works in the game engine.

Actually, I think using the set-up in G_ok is the only way that makes sense: having logic bricks on the proxy object would be weird, because it's not clear what role it plays in the scene. Is it even converted? However, maybe there should be an easier way to do this that doesn't involve any Python.

Tested in Blender 2.63.2, r46163.%%%

%%%The BGE is using the mesh's parent (the original armature from the group) instead of the proxy object, which is why logic on the proxy does nothing.%%%

%%%Yeah... Really, I think that's the way I'd want it to be.

How about we disable the game logic buttons for proxy objects? That way it would at least be clear that you're meant to do it another way. To address the issue with having to use Python, perhaps we could add a toggle to the Action actuator that would let it fetch the action name from a property. Hmm.. actually, is there currently any way to store a message body as a property with logic bricks?%%%
