Loading Animations via C# Script directly from .fbx?

Question

Hey Guys, as the title of this question says, i want to load the animations from my .fbx model via c# (without the UnityEditor class!) and add them to the animation component (also added per script).

 public class AnimatorController : MonoBehaviour {
     
     public string modelName;
         public string aniName;
     public AnimationClip clip;
     void Start ()
     {
         gameObject.AddComponent<Animation> ();
         anim = gameObject.GetComponent <Animation> ();
         clip = Resources.Load (modelName + ".fbx/idle", typeof(AnimationClip)) as AnimationClip;
         clip.legacy = true;
         anim.AddClip (clip, "idle");
         anim.wrapMode = WrapMode.Loop;
         anim.playAutomatically = true;
         anim.Play ("idle");
     }
 }

After that clip still is null.

This is what the .fbx looks like in the project window:

I need that script to load and animate models without creating a prefab or using the inspector.

Thanks in advance.

Answer 1

What I have tried:

I was trying to solve the problem but with a .blend file instead.

First of all, this:

 Object animation_clips = Resources.LoadAssetAtPath("PATH-TO-YOUR-MODEL", typeof(AnimationClip));

returned only one animation clip, so, I thought that:

 Object[] animation_clips = Resources.LoadAssetAtPath("PATH-TO-YOUR-MODEL", typeof(AnimationClip[]));

would return all, however, I was wrong, It returned an empty array.

Solution that I found out [using ModelImporter format]:

After some research, I found out this solution:

 ModelImporter model_imp = AssetImporter.GetAtPath("PATH-TO-YOUR-MODEL") as ModelImporter;

For instance, to print all the animations, you can simple do:

 foreach (var anim_clip model_imp.clipAnimations) { Debug.Log(anim.clip); }

Afterwards problem and solution [using AnimationClip format]:

In my case, the animation clips in ModelImpoterAnimationClip format wasn't enough, because I couldn't use them as AnimationClip. So, I found out another solution to make the exact same thing, but loading the animation clips as AnimationClip format, using:

 Resources.LoadAssetAtPath("PATH-TO-YOUR-MODEL", typeof(Motion[]))
 var clips = Resources.FindObjectsOfTypeAll<AnimationClip>();

Now, you can do whatever you want, for instance print:

 foreach (var c in clips) { Debug.Log(c.name); }

I had issue because path to model was wrong. Try this solution:

 string path = Application.dataPath + "/Resources/<model_name>.fbx";
 var assetPath = path.Replace(Application.dataPath, "Assets");
 
 ModelImporter MI = (ModelImporter)AssetImporter.GetAtPath(assetPath);
 ModelImporterClipAnimation[] clips = MI.defaultClipAnimations;
 
 foreach(var clip in clips) { Debug.Log(clip.name); }
