How to edit animation properties in C# script

I am attempting to change animation properties such as "loop time", "mirror" and etc in C# scripts in oder to edit a batch of animation clips. Howerver, it didn't work.

Unity ver: 5.6.3


Here is my test codes,
AnimationClip newClip = AssetDatabase.LoadAssetAtPath(_file, typeof(AnimationClip)) as AnimationClip;
AnimationClipSettings newSettings = AnimationUtility.GetAnimationClipSettings(newClip);
//newClip.wrapMode = WrapMode.Loop;
newSettings.loopTime = true;
newSettings.mirror = true;
AnimationUtility.SetAnimationClipSettings(newClip, newSettings);
EditorUtility.SetDirty(newClip);

AssetDatabase.SaveAssets();
EditorApplication.SaveScene();

Anyone could help me? Thanks!

 

To be clear, "it didn't work" means the property of animation clip ("loop time", etc..) did not change when I saw it in editor mode.

 

heres some code i used awhile back, if it helps you:

Code (CSharp):

1.   private void copyAnimSettings(AnimationClip Source, AnimationClip Targ)  ///SXAnimProperties SourceAProp
2.     {
3.         string ClipName = Source.name;
4.         string SourceAsset = AssetDatabase.GetAssetPath(Targ);
5.  
6.         ModelImporter S_modelImporter = AssetImporter.GetAtPath(AssetDatabase.GetAssetPath(Source)) as ModelImporter;
7.         ModelImporter T_modelImporter = AssetImporter.GetAtPath(SourceAsset) as ModelImporter;
8.  
9.         var clips = T_modelImporter.clipAnimations;
10.         if (clips.Length == 0) clips = T_modelImporter.defaultClipAnimations;
11.  
12.         var S_clips = S_modelImporter.clipAnimations;
13.         if (S_clips.Length == 0) S_clips = S_modelImporter.defaultClipAnimations;
14.  
15.         if(S_clips.Length == 0 || clips.Length == 0) {
16.             Debug.Log("Skipped, clip was no good   -   s: " + S_clips.Length + "   t: " + clips.Length);
17.         }
18.  
19.         foreach (var clip in clips)  {
20.             if(clip.name != ClipName)   {
21.                 Debug.Log("bad clip in list[d]" + ClipName + " " + clip.name);
22.                 continue;
23.             }
24.  
25.             foreach(var S_clip in S_clips)  {
26.                 if (S_clip.name != ClipName)  {
27.                     Debug.Log("bad clip in list[s] " + ClipName + " " + clip.name);
28.                     continue;

Hi Lee,

It works!

I appreciated for your solution!
