How in the world do I nest Animations manually?

This Animation controller has all it's animation states nested under the controller. I think this is a great way to organize. Only issue is I can't do this myself, the only way I've seen to get this setup is with "Auto Generate Animation" when using a UI>Button, but if I try to setup this type of relationship with other objects manually, I simply can't nest the animations under the object.

Functionally it's almost the same except other animation controllers can't access another controller's animations if they are nested, which is fine but I just want to know how to accomplish this. Is it possible to do this manually on our own?

TL;DR: UIButton's Auto Generate Animation does something I can't seem to recreate.

 

Perfect! Exactly what I needed to see.

 

It is working and I can add new AnimationClips to Controller just fine, but when I try to add this clip to newly created empty state it gives me an error :
Animation clip 'End' is not retargetable. Animation clips used within the Animator Controller need to have Muscle Definition set up in the Asset Importer Inspector.
Any tips?

 

Possible feature request: could we have AnimationClips be nested in the AnimatorController by default? I don't think I've ever once reused an AnimationClip in a different controller, and associating clips with the correct controller is....challenging at best.

 

It's not "imported", I've just added it like this:

Code (CSharp):

1. AnimationClip clip = new AnimationClip();
2. clip.name = clipName;
3. AnimatorController controller = Selection.activeObject as AnimatorController;
4. AssetDatabase.AddObjectToAsset(clip, controller);
5. AssetDatabase.ImportAsset(AssetDatabase.GetAssetPath(controller));

error appears when I try to assign such nested clip to motion field


BTW, Is there a way to remove nested clip?

 

Here is the method Unity uses to generate a transition

Code (csharp):

1.  
2. private static AnimationClip GenerateTriggerableTransition(string name, AnimatorController controller)
3. {
4.     AnimationClip animationClip = AnimatorController.AllocateAnimatorClip(name);
5.     AssetDatabase.AddObjectToAsset(animationClip, controller);
6.     State dst = AnimatorController.AddAnimationClipToController(controller, animationClip);
7.     controller.AddParameter(name, AnimatorControllerParameterType.Trigger);
8.     StateMachine stateMachine = controller.GetLayer(0).stateMachine;
9.     Transition transition = stateMachine.AddAnyStateTransition(dst);
10.     AnimatorCondition condition = transition.GetCondition(0);
11.     condition.mode = TransitionConditionMode.If;
12.     condition.parameter = name;
13.        
14.     return animationClip;
15. }
16.  

PS: If you are interested i've made a little class to help me create animator controllers with custom states just like the Auto Generator in Unity. Here's the link: http://pastebin.com/ZLjZ1gda

 

Hey, thanks! This work just great!
