Problem

Scripts write input straight to the canvas with no notion of whether a human is also using it. Grab the mouse mid-script and you both fight for the cursor: your click lands, the bot's lands on top, and neither of you gets what you asked for. Short of disabling the plugin there is no way to intervene.

Separately, what the bot emits does not match what a real mouse produces. Every click carried a MOUSE_ENTERED/MOUSE_EXITED pair that no human click sends, and cursor position was tracked in a bot-only field that real motion could never update, so the layer never knew where the actual pointer was.

What this does

Scripts now emit through a new util/input package. Real input on the game canvas takes ownership: scripts pause, the gesture in flight aborts, anything held down is released, and the bot resumes after an idle window.

  • InputArbiter decides ownership. Real motion past a threshold, or any real key or button, flips to human. Ownership returns after an idle period, suppressed while a key or button is still held down.
  • InputLoop serialises gestures, so two scripts cannot interleave a press and a release. Aborting unwinds cleanly rather than stranding a held button.
  • AwtEmitter dispatches events; PointerState holds position, written by both real and synthetic input.
  • CanvasInputListener observes only. It never consumes or transforms events.

Emission now matches real input: the click triad without the spurious enter/exit pair, and canvas boundary crossings tracked so leaving and returning looks like a pointer that exists.

Configuration

Three new settings in MicrobotConfig, including an off switch. Set disableInputYielding and behaviour reverts to today's: no yielding, no arbitration. Motion threshold (default 10px) and idle resume (default 1800ms) are both tunable.

Fixes found along the way

  • A takeover mid-typeString sprayed the rest of the string into whatever widget the human had just opened.
  • A key held when the window lost focus stayed down forever, since the release never arrives and a stale held key suppresses idle resume.
  • The cursor overlay drew beneath the right-click menu.
  • The moveMouseOffScreen antiban setting never left the canvas. MouseMotion clamps its destination to the canvas (limitByScreenWidth is max(0, min(width - 1, value))), so the cursor walked to the edge and stopped while the client went on believing a pointer was over it. The setting, its chance slider and the Rs2Antiban calls were all wired to something inert.

Testing

Eight new test classes covering emission shape, arbitration, yielding, gesture abort, focus loss, boundary crossings and held-key release. Full suite green: 1391 tests, 0 failures.

Live-verified: motion, key and button takeover; idle resume; held-button suppression; the kill switch; focus-loss release; and a fixed/resizable display switch.

Notes for reviewers

The riskiest surface is Global's wait helpers, which now check ownership so a paused script does not spin through its sleeps. Script.run() gates on the same signal.

InputDiagnostics is a read-only readout of arbiter state, off unless -Dmicrobot.inputDebug=true. It exists because this subsystem fails silently: "the bot stopped" has three causes (listener never attached, threshold never tripped, waits never observed the flag) that are otherwise indistinguishable. It is also why InputArbiter carries several accessors with no production caller.

Worth knowing: RuneLite reuses one Canvas across display modes, so CanvasInputListener's re-attach path is currently untriggered. It is kept as a cheap identity check because a renderer swap is a plausible trigger nobody has tested.

Walkthrough

This change adds human-input arbitration for mouse and keyboard activity. It tracks pointer state, observes canvas events, coordinates synthetic gestures, and releases held keys. It also pauses scripts and waits during human control, updates overlays and diagnostics, and changes run configurations to use runelite.client.main with argument-file classpath shortening.

89-103: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The held-key release does not run on two early-return paths.

run() returns at Line 90 for tutorial island and at Line 94 for a blocking event. Both returns happen before the InputArbiter.isHuman() check at Line 98. On those paths a takeover leaves every bot-held key down, which contradicts the stated rule that a takeover releases held keys.

Move the takeover check above the early returns.

Two things worth flagging that are not visible in the diff.

Rs2Keyboard.keyRelease(int) is now a no-op for a key that was never held. It only emits KEY_RELEASED for a key HELD_KEYS saw go down, so that a press suppressed during a takeover is not followed by a release with no press before it. In-tree this only affects Rs2Camera, which pairs keyHold/keyRelease correctly, so behaviour there is unchanged. Out-of-tree scripts calling keyRelease standalone, without a matching keyHold, will now get nothing where they previously got an event. That is deliberate, since an unmatched KEY_RELEASED is not a shape a keyboard produces, but it is a behaviour change for script authors and I would rather say so than have it found later.

The off-canvas path has not been exercised against a live client yet. The earlier live verification (motion, key and button takeover, idle resume, kill switch, focus-loss release, display-mode switch) predates the moveMouseOffScreen fix and the three fixes from the second review round. Those are unit-verified only. The client-thread ordering in NaturalMouse.moveOffScreen is the piece most likely to behave differently in a real client than under a mocked isClientThread().

I have a harness for that live run and will post the result here.

161-166: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

The free axis can be drawn one pixel off the canvas.

random.nextInt(0, client.getCanvasWidth() + 1) is exclusive of the bound, so it returns up to getCanvasWidth(). The last in-canvas column is getCanvasWidth() - 1. The same applies to the vertical draw. When exitHorizontally is false, targetX can therefore already be outside, which makes the second call cross on the axis the code intends to keep inside.

MouseMotion clamps, so nothing breaks today. The bound still does not match the stated intent.

♻️ Proposed bound fix
-        int targetX = exitHorizontally ? horizontal : random.nextInt(0, client.getCanvasWidth() + 1);
-        int targetY = exitHorizontally ? random.nextInt(0, client.getCanvasHeight() + 1) : vertical;
+        int targetX = exitHorizontally ? horizontal : random.nextInt(0, client.getCanvasWidth());
+        int targetY = exitHorizontally ? random.nextInt(0, client.getCanvasHeight()) : vertical;

39-45: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Trail recording is applied inconsistently.

move records a trail point. handleClick moves through emit.move and records nothing. scroll records the trail point for its own target, while drag records nothing for its press and release points, because moveTowards records only when Microbot.naturalMouse is null. The debug overlay therefore shows a trail that depends on which path produced the motion.

This affects the overlay only, so it is not urgent.

Also applies to: 196-197, 235-246

Live run done, against a real client. 10/10.

Step Driven by
PASS emission: click is a bare triad bot
PASS off-canvas: the bot actually leaves bot
PASS off-canvas: the return announces itself bot
PASS keyboard: a hold pairs with exactly one release bot
PASS takeover: your motion stops the scripts person
PASS takeover: a held button keeps the bot out person
PASS resume: the bot takes input back when you stop person
PASS focus: alt-tab drops what you were holding person
PASS kill switch: yielding off means no yielding person
PASS cleanup: yielding back on bot

This closes the gap I flagged earlier. The two off-canvas steps and the client-thread ordering in NaturalMouse.moveOffScreen had only ever been exercised under a mocked isClientThread(); they now hold against the real thing.

The harness asserts on what actually reached the canvas rather than on what the emitter believes it sent: it attaches its own listeners and labels every event by whether BotEventGuard was raised. So "click is a bare triad" fails if an ENTERED/EXITED pair shows up, and "the bot actually leaves" fails if PointerState says outside but no MOUSE_EXITED arrived. The takeover step calls the real Script.run() on a probe instance rather than reimplementing the gate.

Two things it does not cover, both unit-tested only: a mid-string typeString takeover (it would type into the chat box) and a mid-drag gesture abort (needs tighter human timing than is reasonable to ask for).

The harness itself is not in this PR. The repository takes client changes only, and it is a development tool.

Scripts now emit through an input layer that gives way to real input. Moving
the mouse or pressing a key on the game canvas pauses scripts, aborts the
gesture in flight, releases anything held down, and resumes after an idle
window. Threshold, delay and an off switch are configurable.

What the bot emits now matches the shape of real input: the click triad
without the spurious ENTERED/EXITED pair, position read from actual events
instead of a bot-only field that human motion could never update, and canvas
boundary crossings in both directions, so leaving and returning looks like a
pointer that exists.

Crossing outward also fixes the moveMouseOffScreen antiban setting, which
never left the canvas. MouseMotion clamps its destination to the canvas, so
the cursor walked to the edge and stopped there while the client went on
believing a pointer was over it.

Fixes found along the way:
- a takeover mid-typeString sprayed the rest of the string into the widget
- a key held when the window lost focus stayed down forever
- the cursor overlay drew beneath the right-click menu
All three referenced a module that does not exist. The Gradle project is
named runelite with a client subproject, so IntelliJ's module is
runelite.client.main, where the files asked for client.main and, in the proxy
one, plain client. With no module to resolve, the generated command line
carried no classpath and every run died before reaching main().

Shorten the classpath through an args file, since the full one exceeds what
Windows accepts on a command line.

Drop the JDK pin from the two configs that carried one. It was an SDK name
from one person's IntelliJ, and the project compiles to Java 11 bytecode and
builds on Java 11 in CI, so the project SDK is already the right answer.
