SmallifyMob

Keep baby mobs small by locking their growth with a configurable Name Tag trigger.

When a player renames a baby mob to the configured activation name (default: stop grow), the mob’s age is locked, preventing it from growing up. Optionally, when the name no longer matches, growth can be unlocked automatically.

Features

• Lock baby mob growth by Name Tag.
• Toggle plugin and behavior at runtime via commands.
• Simple, minimal configuration.

Commands

• /smallify reload — reloads the config.
• /smallify enable — toggles the plugin on/off.
• /smallify enableGrow — toggles auto-unlock growth after rename off the activation name.
• /smallify activationName <nametag> — sets the activation name.
• /smallify info — prints current settings.

Required permission for commands: smallifyEventHandler.commands

Permissions

• smallify.useNametag — allows using a Name Tag to lock/unlock growth on entities.
• smallifyEventHandler.commands — allows using /smallify commands.

Config file

# master switch. When true, the plugin logic is active; when false, it does nothing.
enable: true
# when true, if a mob was previously locked and its name no longer matches the activation name, growth is unlocked so it can grow normally.
enable-grow-after-rename: true
# the exact Name Tag text that locks baby mob growth. Comparison is case-insensitive and trims whitespace.
activation-name: stop grow

[How it works]

• On right-click with a Name Tag, if the entity name equals activation-name and the entity is a baby ageable mob, its age is locked.
• If the name doesn’t match and enable-grow-after-rename is true, any existing age lock is removed so it can grow.

Installation
