Re: Scripting Animation Layers, Part2

[André Adam <a_adam(at)49games.de>]

Heya, I got something working, sneaking through the backdoor (iterating 
the mixerclips instead of the tracks). I also logged a bug for the 
missing Type property for animation layer tracks. If I'm not the only 
one who wants to match Anim Layer IDs with Anim Layer names, this works:

Cheers!

   -André


function fGetAnimLayers(oModel){
 var aAnimLayers = new Array();
 var eClips = new Enumerator(oModel.Mixer.Clips);
 while(!eClips.atEnd()){
   if(eClips.item().Type == "mixerlayerclip"){
     aAnimLayers.push(eClips.item().Name);
     aAnimLayers.push(eClips.item().Owners(0).Parameters("layer").Value);
   }
   eClips.moveNext();
 }
 return aAnimLayers;
}


var oModel = Selection(0).Model;
if(oModel.HasMixer()){
 var aAnimLayers = fGetAnimLayers(oModel);
 if(aAnimLayers.length > 0){
   for(var i=0; i<aAnimLayers.length; i+=2){
     LogMessage(aAnimLayers[i] + ": " + aAnimLayers[i+1]);
   }
 }
 else{
   LogMessage("No Anim Layers!");
 }
}
else{
 LogMessage("No Mixer!");
}
