See comments inside for full details on how this project works. Click around on the background to spawn walking cat clones that march across the screen to the right, always layering correctly according to how far 'away' they are. This system does three main things... 1. Sizes the clones according to their Y position so higher clones look farther away, to match the grassy field background image. 2. No longer uses a list to find the layer... Instead, it sends a broadcast to ask all the existing clones to compare their Y positions with the newly spawned clone. By counting how many have Y position below the new one, we know how many layers to move. 3. Walks the clones at a speed appropriate for their 'distance'. Credit to @Locomule for the original demo idea. And to @griffpatch for the Scratch cat walk-cycle, of course!
