Set "Anim Layers" options for Maya 2011

[Long Phan]

I'm using Maya 2011. I'm trying to get the command to select (hi-lite) an "Animation Layer". I also need the command to set the "Key in Selected Layer(s)" option. Maya 2011 doesn't seem to document this very well either in "mel" or "Python". Does anyone have any advice?

Since I didn't know the answer to the Animation Layer question immediately, I can tell you what my process was for finding the solution...

First, I will turn on Echo All Command for the Script Editor, and do the actual Select Objects for the Anim Layer. The print out tells me that it uses a MEL command: layerEditorSelectObjectAnimLayer 

This takes a []string array of anim layers, and selects them. From here, you could use maya.mel.eval() and call it with an array format like  "{AnimLayer1}".

But if you want to get a more programmatic way to get the objects, I would then type the mel command: 

    whatIs layerEditorSelectObjectAnimLayer

This shows me the mel file that contains this definition. When I open the mel script up and read the code, I see that it recursively calls that same function on the layers, looking for the root layer, to which is then uses the python equivalent:

    cmds.animLayer("AnimLayer1", q=True, attribute=True)

This will dump out all the attributes of that Anim Layer, like:

# Result: [u'pSphere1.visibility',

 u'pSphere1.translateX',

 u'pSphere1.translateY',

 u'pSphere1.translateZ',

 u'pSphere1.rotateX',

 u'pSphere1.rotateY',

 u'pSphere1.rotateZ',

 u'pSphere1.scaleX',

 u'pSphere1.scaleY',

 u'pSphere1.scaleZ'] # 

But I would suppose what we want really is the object list. So I would loop over those results, and split out the object name into a set, so that the results are unique:

objs = set(attr.split('.')[0] for attr in cmds.animLayer("AnimLayer1", q=True, attribute=True))

# Result: set([u'pSphere1']) # 

Hope that helps!

Thanks for responding Justin.  What you're talking about is how to get the attributes associated with an "Anim Layer".  My question is how do you select an Anim Layer?  I've found the soluction though. 

 

source "C:/Program Files/Autodesk/Maya2011/scripts/startup/buildSetAnimLayerMenu.mel";

selectLayer("AnimLayer1");
