Animation Not Working On Empty Parent GameObject !

Hi guys,

I have three gameobjects which are children of empty gameobject. When i add keyframes for parent object and hit play preview, it seems working. But animation is not working when i start the game.

NOTE: When i animate three gameobjects separately, it works...

These three gameobjects have their pivots on corners so changing their rotations separately makes them apart too. So i have to animate parent object. Can u help me ?

 

I fixed it by unchecking "Apply Root Motion" on Animator component. Now it works even if i make animation for parent object.
