These settings allow the sprite sheet to be animated, have the same detail as the normal image, and keep the max file size down by limiting the max texture sheet size to 1024 pixels.
Next, we need to update the sprite sheet so that it knows the boundaries for each of the animation frames in the sheet. To perform this, in Inspector, click on Sprite Editor.
This is designed to help us break the image based on the X and Y values we want to. For example, if each frame of the animation is
32 pixels wide on X and
32 pixels wide on Y, we can use the Sprite Editor to cut the image into smaller images based on that size.
