So I saw that Animation Controller and Animator are available under frames as shown here
now I tried using it but realized that it isn’t “Rigged”, is it possible to rig 2D objects or use Animation Controller to 2D objects itself?
I dont think animation controllers / animators are for 2d objects… Do you want to animate GUI objects or just like a singular one?
You don’t…
You need write into Localscript, a sprite animation system
and many making images and spritesheets, however depends how you want
there is tutorials for it in Developers Forum
