Size Rayguns
Size Rayguns adds two ray guns, Shrink Raygun and Growth Raygun, that change the size of whatever they hit.
What it does
Right-clicking with either raygun fires a beam that scales the target up or down, so a player can shrink a mob or enlarge it. Shift-right-clicking applies the change to the holder instead, and the player's reach changes with their size. The mod requires Pehkui, which provides the scaling system it depends on.
Both rayguns are for players who want to alter the scale of mobs and players in a world. The mod is published for Forge and NeoForge, with files for 1.20.1 – 1.21.3, and it runs on client and server, so the server and every player need it. The code is under All rights reserved and is not open source.
Key features
Shrink Raygun

Self-scaling with shift
Shift-right-clicking scales the holder up or down, and reach follows the new size.
