I can now drag the .prefab into the game and if i start the game i see the Animation.
The Problem is i can't acces the file for the Animation anymore i checked on the example there it is the same what could be the reason for that?
Bothe of them don't work for me alot of Things which appear in the examples don't appear in my files there has to be something wrong with my files thought it Looks the same as the example.Seems like i have to find another way to get my animations into unity.
