Proportionality
by Frank1o3
Proportionality lets a player change body size from an in-game scale screen, with the server setting the allowed range.
What it does
Scaling a player also scales several attributes in proportion, including health, movement speed, jump strength, attack damage, step height, interaction reach and fall damage. Each attribute follows its own exponent, so server owners can tune how strongly each one responds to a change in size.
The mod is built for both single-player and multiplayer play. Scale values are managed on the server and synchronized with connected clients, and the server checks every change before it takes effect. The server also publishes its minimum and maximum scale, so a limit such as 2 or 16 keeps players from picking a size the server does not allow.
Fabric API and FranklyLib are required. The server needs the mod, while players may leave it out and still join. Files target 26.2 only, with 1.1.1 for 26.2 as the latest, and the code is released under the MIT License as open source.
Key features
In-game scale screen
A screen opens from a key press, and a slider sets the new size, which the player confirms.
Proportional attributes
Health, speed, jump strength, attack damage and reach change with the player's size, using configurable exponents.
Server-set limits
Server owners define the maximum scale, and the slider shows the allowed minimum and maximum to players.
Saved size
A chosen scale is stored automatically and restored after a player reconnects.
Config reload
Operators reload the scaling configuration without restarting the server.

Use cases
Multiplayer servers
Server owners cap the scale range and decide how each attribute responds, so players can resize within the limits set for their world.
Who it’s for: Server owners who want scaled players on multiplayer servers, and players who want to change their size in single-player or multiplayer.
