Hi, I just started working with unity and I use a udemy tutorial to learn unity. How I've created the animation: created a Player - GameObject in the scene added an animation (PlayerIdle.anim) in the Animation - Tab added one image to the animation (created out of a sprite sheet) Then I start the game the animation works. After closing unity and reopening the project the animation-tab is completly empty (Player - GameObject is selected in the Hierarchy), but the animation-files are still in the directory I've saved them to. What I've tried so far: Created only the animation-file without adding any image to it. Animation is still lost after restart. Saved the anim - Files in different directions (Assets/Sprites/Player/, Assets/Animations/). Animation is still lost after restart. Deleted the whole project and cloned it again from GitHub. Animation is lost after opening the project but the anim - file is there. I found out that everytime I restart unity it creates a new Player.controller file. So there is a Player.controller, Player 2.controller and so on but the Player - gameobject is still named Player in the inspector. I'm totaly confused about that behavior. Thank you for any help in advance. I don't know which file I should upload, please tell me if a file is needed.
