StatTweaker

Scripts written with the StatTweaker commands set the attributes and base values of mobs, items, armor and tools. Every line in a script starts with mods.StatTweaker, and the example file StatTweaker.zs shows how to add the import. Parameters are written in the form parameter name, parameter type, and command autocompletion helps while typing them.

Parameters accept strings, integers and floating-point numbers. An EntityName is a String literal in double quotes, matching the registry name used when summoning the entity. Int and Integer take whole numbers, while Float and Double take numbers with decimal precision. A question mark after a type makes that value optional, which leaves the stat unchanged. Changes apply to a custom mob's base attributes, and known exceptions are listed by the author.

The mod is intended for balancing modpacks, where a pack maker tunes stats in scripts rather than editing configuration files by hand. It requires ASJCore and CraftTweaker, and it runs on client and server, so both sides need the same version. Some material-changing functions affect only the material itself, not the items made from it, and each function works with one other mob, item or material because of how the code was written.
