The key of animation will add, although the addition is not operated.

Because I used a class from Editor class and wanted to reduce a decimal point,

I made the following sources.

 cmnGUIPixelEditor.js
 class cmnGUIPixelEditor extends Editor
 {
     function OnInspectorGUI () {
         var myTarget : cmnGUIPixel = target as cmnGUIPixel;
         myTarget.m_Pixel        = EditorGUILayout.Vector2Field ("Pixel : ", myTarget.m_Pixel);
         myTarget.m_Pixel.x        = Mathf.Round(myTarget.m_Pixel.x);
         myTarget.m_Pixel.y        = Mathf.Round(myTarget.m_Pixel.y);
         if (GUI.changed){
             EditorUtility.SetDirty (myTarget);
         }
     }
 }
 cmnGUIPixel.js
 var m_Pixel : Vector2            = Vector2.zero;

I added two keys to m_Pixel to let you make animation. (In Animation in Window)

And a key of m_Pixel adds it without permission in "time" of the current mouse cursor position though I do not add a key when I move "time bar" with a mouse for confirmation.

The key is not added when I delete the following processing even if I move a thyme bar and comes back normally.

 myTarget.m_Pixel.x  = Mathf.Round(myTarget.m_Pixel.x);
 myTarget.m_Pixel.y  = Mathf.Round(myTarget.m_Pixel.y);

How should I evade it?

• Usually, it is not added even if it moves a time bar.

Any help would be appreciated, Thanks!
