Sprite animation with 2 images won't animate..

So I have a sprite, and I want it to perform a walking animation whilst one of the WASD keys are held down. There’s literally two images in the animation, yet for some reason every time I would make the animation, placing both onto the window, the character still stays put.

I’d use Add Curve > Sprite Renderer > Sprite to add them to the animation, however, if I was to use something other than “Sprite”, and use Add Curve > Sprite Renderer > Color, it would work perfectly fine.

What am I doing wrong here? The animation component is set onto the sprite, and the default animation is set to Walk.

Thanks.

Oh I see. can you try with an animator and not just animation?
