Pehkui - Entity Size Modification in Minecraft

This mod enables you to alter the dimensions of nearly all entities in the game, allowing you to either shrink or enlarge them. This opens up new possibilities for gameplay and creating unique scenarios.

Developers of other mods can utilize the provided API to manage entity sizes and configure the speed at which their dimensions change.

Important Information

When the mod is removed, all entities revert to their standard sizes. Reinstalling the mod will not restore previous scale settings.

Commands for Size Management

If you don't have other mods that add ways to change sizes, you can use the /scale command to view and configure entity scales (requires operator permissions):

/scale set <value> [<entity>]
/scale set <scale_type> <value> [<entity>]
/scale (add|subtract|multiply|divide) <value> [<entity>]
/scale (add|subtract|multiply|divide) <scale_type> <value> [<entity>]
/scale get [<entity>]
/scale get <scale_type> [<entity>]
/scale compute <scale_type> [<entity>]
/scale delay set <ticks> [<entity>]
/scale delay set <scale_type> <ticks> [<entity>]
/scale delay get [<entity>]
/scale delay get <scale_type> [<entity>]
/scale reset [<entity>]
/scale reset <scale_type> [<entity>]
/scale nbt get [<entity>]

Persisting Settings After Respawn

To maintain scale settings after player respawn, use the following commands:

/scale persist set (true|false) [<entity>]
/scale persist set <scale_type> (true|false) [<entity>]
/scale persist get <scale_type> [<entity>]
/scale persist reset [<entity>]
/scale persist reset <scale_type> [<entity>]
