Outline Cat (ShellAtol's Handy Stuff)
by shellatol
Outline Cat is a datapack that gives players a craftable stack for summoning an invisible cat whose outline stays visible.
What it does
Crafting the Outline Cat Summoner Stack takes six String in the same pattern used by Wolf Armor. The stack comes already set up, so a player places it and runs its command block to bring the cat into the world without typing the long command by hand. The cat itself stays invisible, and its glowing effect draws only the outline on screen, so the cat remains visible as an outline while the body does not render.
The mod suits survival play, where getting the setup normally means entering a long command. It is a lightweight datapack, and its only added content is the craftable summoner stack. Only the server needs the mod to be installed, so players may leave it out. The code is not open source, and the mod is released under All rights reserved. Files exist for Fabric, Forge, NeoForge and Quilt, and a datapack form is also published, covering 1.21 and 1.21.1.
