Spritesheets

SpriteSheet is really an ordered collection of sprites from the same base image.

const spriteSheet = new ex.SpriteSheet({
  image: imageRun,
  sprites: [...]
})

Uniform Grid Based Spritesheet

If you spritesheet is a neat grid there is a static builder for you to slice up that image source. Most sprite sheets are tightly packed like so.

Some source spritesheets may have margin between sprites and an offset, like these playing cards from Kenny.nl

const kennyCardsImage = new ex.ImageSource(kennyCardsImageSrc);

const spriteSheet = ex.SpriteSheet.fromImageSource({
    image: kennyCardsImage,
    grid: {
        rows: 4,
        columns: 14,
        spriteWidth: 42,
        spriteHeight: 60
    },
    spacing: {
        // Optionally specify the offset from the top left of sheet to start parsing
        originOffset: { x: 11, y: 2 },
        // Optionally specify the margin between each sprite
        margin: { x: 23, y: 5}
    }
});

Sparse Spritesheet

You can also build a spritesheet from a list of different sized source views using SpriteSheet.fromImageSourceWithSourceViews method

const ss = ex.SpriteSheet.fromImageSourceWithSourceViews({
  image,
  sourceViews: [
    { x: 0, y: 0, width: 20, height: 30 },
    { x: 20, y: 0, width: 40, height: 50 },
  ],
})
