Drag and drop it onto a gameobject, select that gameobject. (that's for legacy animations) Drag and drop it onto a gameobject, select that gameobject, click on the animation in the Animator view. (that's for animator animations)
So it has to be on a gameObject in order to edit it? Also, is there a way to delete items from the Clip drop down in the Animation view?
Where is the size? And also what is "Samples" for? The default value is 60. Oh the Samples is how many FPS I think. I still don't know how to remove the Clip from the drop down.
https://docs.unity3d.com/Manual/class-Animation.html and https://docs.unity3d.com/Manual/AnimationScripting.html (the last part, about sampling) EDIT: This is for the legacy animation system, but it seems you are using the animator. I wan't clear on what you were using so I took a guess. The second link does sort of explain what "Sample" does though, but feel free to ignore the first one.
I got it! In order for a clip to be in the Animation clip drop down, it also has to be in the Animator. When you delete the state from the Animator, it will also be deleted in the Animation drop down. The .anim file will still exist. When you delete the .anim file from the Project view, the state in the Animator and also the clip in the Animation drop down will also be deleted.
Thank you for the links but they scare me! Why is Animation a legacy tool? What is the tool that replaced it?
You are not using the legacy tool. You are in fact using the current "animator" tool. I was just providing info about both since I wasn't sure what you were using I will concur that calling one component "Animator" and the other "Animation" makes it a bit confusing when talking about animations in general
Since now we know what you're using, this is the page to read : https://docs.unity3d.com/Manual/AnimationOverview.html
Also, I have a lot of clips for 1 Animator. What happens if the drop down becomes too long? How do I select the clip to edit in the Animation view?
