JsMacros API Reference ​

Version: dev
Minecraft: 26.2

This reference is generated from the sources for this Minecraft target. Signatures, raw Minecraft types, and behavior can differ between versions; the version selector in the navigation bar opens another target. New to JsMacros? Start with the Guide.

Start here ​

  • Libraries (17) — The global objects a script starts with: Chat, World, Player, Hud, JsMacros, and more.
  • Events (57) — Typed signals from the game. Subscribe with JsMacros.on, wait with waitForEvent, and read each event page for its payload and cancellation rules.
  • Classes (353) — Objects returned by libraries and events: entities, blocks, inventories, draw elements, screens, and builders.
  • Type namespaces (7) — Stable script names for Java types, such as EntityHelpers.Horse. They are for instanceof and static access, not a second class list.

Common entry points ​

  • Chat — Provides client chat, server messaging, overlay display, and text-formatting functions to scripts as the Chat variable.
  • World — Functions for getting and using world data.
  • Player — Functions for getting and modifying the player's state.
  • Hud — Screen, overlay, texture, and window-state APIs exposed to scripts as Hud.
  • JsMacros — Script library for event listeners, script execution, and profile services.
  • KeyBind — Gets and changes key and keybind states through the script global KeyBind.

How to read a page ​

  • The large title is the script name. The small monospace line is the fully qualified Java name used by Java.type and reflection.
  • read-only marks a field you should not write. It is not a constant and can still change over time.
  • Since is the JsMacros version that introduced the member, not the Minecraft version.
  • Overloads share a heading but keep separate signatures and descriptions. Read the parameters to choose one.
  • A compatibility stub can exist on a target without the full behavior. Read the description, not just the signature.

Script type namespaces ​

JavaScript and Python scripts get these globals automatically. They are read-only aliases of real Java types, so instanceof and isinstance work without a package name.

  • EntityHelpers (80) — Lets scripts identify entity helpers through the EntityHelpers global, without knowing their Java package names.
  • HitResults (3) — Lets scripts distinguish block and entity targeting results through the HitResults global.
  • Inventories (18) — Lets scripts identify inventory wrappers through the Inventories global, instead of matching screen-name strings.
  • NBTHelpers (4) — Lets scripts distinguish numbers, lists, and compounds in NBT data through the NBTHelpers global.
  • RenderElements (14) — Lets scripts identify 2D and 3D drawing elements through the RenderElements global.
  • ScriptClasses (2) — Gives scripts access to image creation and key-tracking utilities through the ScriptClasses global.
  • Widgets (7) — Lets scripts identify buttons, sliders, and other widget helpers through the Widgets global.
