Can I just attach this to a gameObject and it will automatically blur?
So I tried putting it as a component to the gameObject with SpriteRenderer, it didn't make it blurry, instead it added a Camera Component. I change the z-value of the gameObject for the camera and it made the other sprites blurry, but not itself, as I expected.
Anyway, I'll try to tinker this shader a little bit and learn from it. Thanks for the shader!
