This project shows the ways I discovered to show multiple images with a single costume. They have different limitations. The middle and right ones have some glitches on my mobile, but the small version looks like doesn't. All: - no distortion effects allowed. - only this small images without JSON editing Left: - 16 images / costume (64 doesn't work on mobile) - only this can change all of the image - only 90° rotations possible - can't change size - must be stamped (no hqpen) Middle: - 4 images / costume - doesn't work on mobile - can't change all of the image - arbitrary size and rotation - compatible with hqpen and the mosaic effect Right: use left/16 instead for small images - 16 images / costume - doesn't work on mobile - it is the left and middle effects combined - can't change size - only 90° rotations - can't change all of the image (not visible because every background is white) - must be stamped (no hqpen) How does this work? When Scratch displays a bitmap costume, then it takes the color of the nearest pixel of the costume. If the sprite has 50% size or 20 pixelate effect = 2x2 pixels (if the costume has 0.5x0.5 pixels then other numbers) then Scratch tries to sample the costume at the shared corner of 4 pixels. Pixelate effect (middle image): if a little warp or fisheye effect is applied, then that decides which of the 4 pixels to choose. Size (left image): small changes in the size and small rotations can choose one pixel of the 4. These effects can be combined by making the pixelate effect output a texture atlas for the size trick.
