Package-level declarations

Safe access to a command callback's argument array. A command trigger's value is a string[], but JS-style indexing (args[0], args.length) isn't guaranteed by the bytecode compiler — these helpers are plain method calls, which always compile cleanly.

Lightweight wrapper around a block at a position.

Passed as the final argument to cancellable trigger callbacks. Call cancel to stop the underlying game action (e.g. hide a chat message). Scripts:

Chat helpers. import { ChatLib } from 'ratph6.jim.api'.

A persistent multi-line HUD overlay. import { Display } from 'ratph6.jim.api'.

Tracks every Display so the HUD hook can render them each frame.

Lightweight wrapper around a Minecraft entity, returned to scripts.

The catalogue of events you can register a trigger for, in the spirit of ChatTriggers' TriggerType. Pass one to Jim.register:

Lightweight wrapper around an item stack.

The primary scripting entry point. Register triggers with an Event and an arrow-function callback that takes a single argument (the event's primary value):

Raw key state. import { KeyBind } from 'ratph6.jim.api'.

Small numeric helpers for scripts. swc4j compiles to JVM bytecode, not a JS engine, so JS globals like parseFloat aren't guaranteed — use these to parse command arguments (which arrive as strings) into numbers.

The local player. All getters return safe defaults when no player exists yet.

A remote, per-player scale table fetched from a URL — the engine primitive behind "global sizes" style scripts. The JSON is an object of { "PlayerName": { "x": 2, "y": 2, "z": 2 }, ... }.

2D HUD drawing. Only valid inside a renderOverlay / HUD trigger, where JIM sets graphics to the frame's draw target (the 26.1.2 GuiGraphicsExtractor, i.e. the renamed GuiGraphics).

Sidebar scoreboard. The 26.1.2 scoreboard read path is non-trivial under the new render model; these are best-effort and may be expanded later.

Current server info. import { Server } from 'ratph6.jim.api'.

A simple global key→value store for script state (numbers, booleans, strings).

Player-list (tab) info.

Matrix transforms for world rendering, in the spirit of ChatTriggers' Tessellator. Only valid inside a renderEntity / postRenderEntity trigger, where JIM binds pose to the entity's live pose stack (already positioned at the entity's origin).

Fluent, chainable handle returned by Jim.register. Every setter returns this so scripts can write Jim.register("chat", "onChat").setContains().setCriteria("hi").setPriority(10).

World / level queries. import { World } from 'ratph6.jim.api'.
