Changing Animation? Sprite? Help!

Hi,

I recently (meaning yesterday) started using Unity. I've been reading tutorials but I can't figure out how to edit a prefab or its animation.

I'm using the Sample Assets package, and I'm trying to change the "robot boy" animations to my own.

Basically all I've done is imported pictures, "sliced" them, and then cried because I don't know how to make animations. (Last sentence is a bit of an exaggeration)

Any help is appreciated.

Thanks!

 

you should have more sprites in order to do an animation
