# Input: Keyboard, Mouse, Touch, and Gamepad
> Phaser provides a unified input system accessed via `this.input` in any Scene. It supports keyboard polling and events, mouse/pointer interaction with Game Objects (click, hover, drag), multi-touch, mouse wheel, and gamepad input. Input can be handled through event listeners or by polling state each frame.

**Key source paths:** `src/input/InputPlugin.js`, `src/input/Pointer.js`, `src/input/keyboard/KeyboardPlugin.js`, `src/input/keyboard/keys/Key.js`, `src/input/keyboard/keys/KeyCodes.js`, `src/input/keyboard/combo/KeyCombo.js`, `src/input/gamepad/GamepadPlugin.js`, `src/input/gamepad/Gamepad.js`, `src/input/events/`, `src/input/keyboard/events/`

## Quick Start (basic keyboard + pointer input)

```js
class MyScene extends Phaser.Scene {
    create() {
        // Keyboard: create cursor keys (up, down, left, right, space, shift)
        this.cursors = this.input.keyboard.createCursorKeys();

        // Keyboard: listen for a specific key event
        this.input.keyboard.on('keydown-SPACE', (event) => {
            console.log('Space pressed');
        });

        // Pointer: listen for click/tap anywhere on the game canvas
        this.input.on('pointerdown', (pointer) => {
            console.log('Clicked at', pointer.x, pointer.y);
        });

        // Pointer: make a Game Object interactive and clickable
        const sprite = this.add.sprite(400, 300, 'player');
        sprite.setInteractive();
        sprite.on('pointerdown', (pointer, localX, localY, event) => {
            console.log('Sprite clicked at local', localX, localY);
        });
    }

    update() {
        // Poll cursor keys each frame
        if (this.cursors.left.isDown) {
            // move left
        }
        if (this.cursors.right.isDown) {
            // move right
        }
        if (Phaser.Input.Keyboard.JustDown(this.cursors.space)) {
            // fire once per press
        }
    }
}
```

## Core Concepts

### The Input Plugin (this.input)

Accessed via `this.input` in any Scene. It is an `EventEmitter` that handles all input for that Scene.

Key properties:
- `this.input.enabled` (boolean) - toggle input processing for the Scene
- `this.input.topOnly` (boolean, default `true`) - only emit events from the top-most Game Object under the pointer
- `this.input.keyboard` - the KeyboardPlugin instance
- `this.input.gamepad` - the GamepadPlugin instance
- `this.input.mouse` - the MouseManager reference
- `this.input.activePointer` - the most recently active Pointer
- `this.input.mousePointer` - the mouse Pointer (pointers[0], distinct from pointer1 which is the first touch)
- `this.input.pointer1` through `this.input.pointer10` - individual pointer references
- `this.input.dragDistanceThreshold` (number, default 0) - pixels a pointer must move before drag starts
- `this.input.dragTimeThreshold` (number, default 0) - ms a pointer must be held before drag starts
- `this.input.pollRate` (number, default -1) - how often pointers are polled; 0 = every frame, -1 = only on movement

Key methods:
- `addPointer(quantity)` - add extra pointers for multi-touch (default is 2; max 10)
- `setHitArea(gameObjects, hitArea, hitAreaCallback)` - set custom hit area on Game Objects
- `setHitAreaCircle(gameObjects, x, y, radius, callback)`
- `setHitAreaEllipse(gameObjects, x, y, width, height, callback)`
- `setHitAreaRectangle(gameObjects, x, y, width, height, callback)`
- `setHitAreaTriangle(gameObjects, x1, y1, x2, y2, x3, y3, callback)`
- `setHitAreaFromTexture(gameObjects, callback)` - use the texture frame dimensions
- `setDraggable(gameObjects, value)` - enable or disable dragging
- `makePixelPerfect(alphaTolerance)` - returns a callback for pixel-perfect hit testing

### Pointers

A `Pointer` object encapsulates both mouse and touch input. By default Phaser creates 2 pointers. Use `this.input.addPointer(quantity)` for more (up to 10 total).

Key properties:
- `x`, `y` - position in screen space (read from `position.x`, `position.y`)
- `worldX`, `worldY` - position translated through the most recent Camera
- `downX`, `downY` - position when button was pressed
- `upX`, `upY` - position when button was released
- `isDown` (boolean) - true if any button is held
- `primaryDown` (boolean) - true if primary button (left click / touch) is held
- `button` (number) - which button was pressed/released (0=left, 1=middle, 2=right)
- `buttons` (number) - bitmask of currently held buttons (1=left, 2=right, 4=middle, 8=back, 16=forward)
- `wasTouch` (boolean) - true if input came from touch
- `velocity` (Vector2) - smoothed velocity of pointer movement
- `angle` (number) - angle of movement in radians
- `distance` (number) - smoothed distance moved per frame
- `movementX`, `movementY` - relative movement when pointer is locked
- `deltaX`, `deltaY`, `deltaZ` - mouse wheel scroll amounts
- `locked` (boolean) - whether pointer lock is active
- `camera` - the Camera this Pointer last interacted with

Key methods:
- `leftButtonDown()`, `rightButtonDown()`, `middleButtonDown()`, `backButtonDown()`, `forwardButtonDown()` - check specific buttons
- `leftButtonReleased()`, `rightButtonReleased()`, `middleButtonReleased()` - check recent release
- `getDistance()` - distance between down position and current/up position
- `getDistanceX()`, `getDistanceY()` - horizontal/vertical distance
- `getDuration()` - ms between down and current time or up time
- `getAngle()` - angle between down and current/up position
- `updateWorldPoint(camera)` - recalculate worldX/worldY for a given camera
- `positionToCamera(camera, output)` - translate pointer position through a camera

### Interactive Game Objects (setInteractive)

Call `gameObject.setInteractive()` to enable input on a Game Object. This uses the texture frame as the hit area by default.

```js
// Default hit area from texture
sprite.setInteractive();

// Custom shape hit areas (Rectangle, Circle, Ellipse, Triangle, Polygon)
sprite.setInteractive(new Phaser.Geom.Circle(32, 32, 32), Phaser.Geom.Circle.Contains);
sprite.setInteractive(new Phaser.Geom.Ellipse(50, 50, 100, 60), Phaser.Geom.Ellipse.Contains);
sprite.setInteractive(new Phaser.Geom.Triangle(0,64,32,0,64,64), Phaser.Geom.Triangle.Contains);
sprite.setInteractive(new Phaser.Geom.Polygon(points), Phaser.Geom.Polygon.Contains);

// Pixel-perfect hit testing (expensive — use sparingly)
sprite.setInteractive({ pixelPerfect: true, alphaTolerance: 1 });
sprite.setInteractive(this.input.makePixelPerfect());
// With alpha tolerance (default 1):
sprite.setInteractive(this.input.makePixelPerfect(150));

// Config object with multiple options
sprite.setInteractive({
    draggable: true,
    dropZone: false,
    useHandCursor: true,
    cursor: 'pointer',
    pixelPerfect: true,
    alphaTolerance: 1
});

// Containers must specify a shape or call setSize first
container.setSize(200, 200);
container.setInteractive();
```

## Common Patterns

### Keyboard Input (cursors, addKey, isDown, JustDown)

**Cursor keys** return an object with `up`, `down`, `left`, `right`, `space`, `shift` Key objects:

```js
this.cursors = this.input.keyboard.createCursorKeys();

// In update():
if (this.cursors.up.isDown) { /* held */ }
if (this.cursors.space.isDown) { /* held */ }
```

**addKey** creates a Key object for any key:

```js
// By string name
const keyW = this.input.keyboard.addKey('W');
// By key code
const keySpace = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.SPACE);
// With options: addKey(key, enableCapture, emitOnRepeat)
const keyA = this.input.keyboard.addKey('A', true, false);
```

**addKeys** creates multiple keys at once:

```js
// Comma-separated string returns { W, S, A, D } Key objects
const keys = this.input.keyboard.addKeys('W,S,A,D');
if (keys.W.isDown) { /* ... */ }

// Object form with custom names
const keys = this.input.keyboard.addKeys({
    up: Phaser.Input.Keyboard.KeyCodes.W,
    down: Phaser.Input.Keyboard.KeyCodes.S,
    left: Phaser.Input.Keyboard.KeyCodes.A,
    right: Phaser.Input.Keyboard.KeyCodes.D
});
```

**Polling vs events:**

```js
// Polling in update() - check every frame
if (keyW.isDown) { /* key is currently held */ }
if (keyW.isUp) { /* key is currently released */ }

// JustDown - returns true only once per press, resets after check
if (Phaser.Input.Keyboard.JustDown(keyW)) { /* fire once */ }
if (Phaser.Input.Keyboard.JustUp(keyW)) { /* released once */ }

// checkDown with duration - throttled polling
if (this.input.keyboard.checkDown(keySpace, 250)) {
    // true at most once every 250ms while held
}

// Event-driven: listen for specific key
this.input.keyboard.on('keydown-SPACE', (event) => { /* ... */ });
this.input.keyboard.on('keyup-SPACE', (event) => { /* ... */ });

// Event-driven: listen for any key
this.input.keyboard.on('keydown', (event) => {
    console.log(event.key); // native DOM KeyboardEvent
});

// Event on a Key object itself
const spaceBar = this.input.keyboard.addKey('SPACE');
spaceBar.on('down', (key, event) => { /* Key object + native event */ });
spaceBar.on('up', (key, event) => { /* ... */ });
```

**Key object properties:**
- `isDown` / `isUp` (boolean)
- `keyCode` (number)
- `altKey`, `ctrlKey`, `shiftKey`, `metaKey` (boolean) - modifier state when pressed
- `duration` (number) - ms held in previous down-up cycle
- `timeDown`, `timeUp` (number) - timestamps
- `repeats` (number) - repeat count while held
- `emitOnRepeat` (boolean) - if true, fires 'down' event on each repeat
- `enabled` (boolean) - can this key be processed

**Prevent browser default behavior:**

```js
// Capture specific keys to prevent browser scrolling etc.
this.input.keyboard.addCapture('SPACE,UP,DOWN,LEFT,RIGHT');
this.input.keyboard.addCapture([ 32, 37, 38, 39, 40 ]);
this.input.keyboard.removeCapture('SPACE');
// Note: captures are global across all Scenes
```

**Common KeyCodes:** `BACKSPACE(8)`, `TAB(9)`, `ENTER(13)`, `SHIFT(16)`, `CTRL(17)`, `ALT(18)`, `ESC(27)`, `SPACE(32)`, `LEFT(37)`, `UP(38)`, `RIGHT(39)`, `DOWN(40)`, `A-Z(65-90)`, `ZERO-NINE(48-57)`, `F1-F12(112-123)`. Access via `Phaser.Input.Keyboard.KeyCodes.SPACE` etc.

### Mouse/Pointer Click and Hover

**Scene-level pointer events** (fire anywhere on the canvas):

```js
this.input.on('pointerdown', (pointer, currentlyOver) => {
    // pointer: Pointer object, currentlyOver: array of interactive Game Objects under pointer
});
this.input.on('pointerup', (pointer, currentlyOver) => { /* ... */ });
this.input.on('pointermove', (pointer, currentlyOver) => { /* ... */ });
this.input.on('wheel', (pointer, currentlyOver, deltaX, deltaY, deltaZ) => { /* ... */ });
```

**Game Object pointer events** (require setInteractive):

```js
sprite.setInteractive();

// pointerdown on this specific object
sprite.on('pointerdown', (pointer, localX, localY, event) => {
    // localX/localY are relative to the Game Object's top-left
    // event.stopPropagation() prevents the event from going further
});

sprite.on('pointerup', (pointer, localX, localY, event) => { /* ... */ });
sprite.on('pointermove', (pointer, localX, localY, event) => { /* ... */ });
sprite.on('pointerover', (pointer, localX, localY, event) => { /* ... */ });
sprite.on('pointerout', (pointer, event) => { /* ... */ });
sprite.on('wheel', (pointer, deltaX, deltaY, deltaZ, event) => { /* ... */ });
```

**Right-click handling:**

```js
this.input.on('pointerdown', (pointer) => {
    if (pointer.rightButtonDown()) {
        // right-click
    }
});

// Disable context menu
this.input.mouse.disableContextMenu();
```

**Pointer lock (FPS-style mouse capture):**

```js
// Request lock on click
this.input.on('pointerdown', () => {
    this.input.mouse.requestPointerLock();
});

this.input.on('pointerlockchange', (event, locked) => {
    // locked: boolean
});

// Read relative movement while locked
// pointer.movementX, pointer.movementY
```

### Drag and Drop

```js
const sprite = this.add.sprite(400, 300, 'item');
sprite.setInteractive();
this.input.setDraggable(sprite);

// Or use config:
// sprite.setInteractive({ draggable: true });

// Drag events on the Scene input
this.input.on('dragstart', (pointer, gameObject) => {
    gameObject.setTint(0xff0000);
});

this.input.on('drag', (pointer, gameObject, dragX, dragY) => {
    gameObject.x = dragX;
    gameObject.y = dragY;
});

this.input.on('dragend', (pointer, gameObject) => {
    gameObject.clearTint();
});

// Drop zones
const zone = this.add.zone(600, 300, 200, 200).setRectangleDropZone(200, 200);

this.input.on('drop', (pointer, gameObject, dropZone) => {
    gameObject.x = dropZone.x;
    gameObject.y = dropZone.y;
});

this.input.on('dragenter', (pointer, gameObject, dropZone) => { /* ... */ });
this.input.on('dragleave', (pointer, gameObject, dropZone) => { /* ... */ });
this.input.on('dragover', (pointer, gameObject, dropZone) => { /* ... */ });
```

Game Object-level drag events are also available:

```js
sprite.on('drag', (pointer, dragX, dragY) => {
    sprite.x = dragX;
    sprite.y = dragY;
});
sprite.on('dragstart', (pointer, dragX, dragY) => { /* ... */ });
sprite.on('dragend', (pointer, dragX, dragY) => { /* ... */ });
sprite.on('drop', (pointer, dropZone) => { /* ... */ });
```

Drag thresholds:

```js
this.input.dragDistanceThreshold = 16; // must move 16px before drag starts
this.input.dragTimeThreshold = 200;    // must hold 200ms before drag starts
```

### Three Levels of Pointer Events

Pointer events fire at three levels (see [reference](references/REFERENCE.md#three-levels-of-pointer-events) for details):
1. **Game Object**: `gameObject.on('pointerdown', (pointer, localX, localY, event) => {})`
2. **Scene per-object**: `this.input.on('gameobjectdown', (pointer, gameObject, event) => {})`
3. **Scene global**: `this.input.on('pointerdown', (pointer, currentlyOver) => {})`

### Input Debug, topOnly, and Multi-touch Config

```js
// Debug visualize hit areas
this.input.enableDebug(gameObject);
this.input.enableDebug(gameObject, 0xff00ff);
this.input.removeDebug(gameObject);

// Let all objects under pointer receive events (not just top-most)
this.input.topOnly = false;
this.input.setTopOnly(false);
```

Multi-touch: set `config.input.activePointers` to reserve pointer slots at startup, or call `this.input.addPointer(num)` at runtime. Access via `this.input.pointer1` through `pointer10`.

### Gamepad Input

Enable gamepads in the game config:

```js
const config = {
    input: {
        gamepad: true
    }
};
```

Access via `this.input.gamepad`. Gamepads are available as `pad1` through `pad4`:

```js
// Wait for connection
this.input.gamepad.once('connected', (pad) => {
    console.log('Gamepad connected:', pad.id);
});

// If already connected, check total
if (this.input.gamepad.total > 0) {
    const pad = this.input.gamepad.pad1;
}
```

**Polling gamepad state in update():**

```js
update() {
    const pad = this.input.gamepad.pad1;
    if (!pad) return;

    // D-pad (boolean properties)
    if (pad.up) { /* d-pad up */ }
    if (pad.down) { /* d-pad down */ }
    if (pad.left) { /* d-pad left */ }
    if (pad.right) { /* d-pad right */ }

    // Face buttons (boolean) - Xbox naming convention
    if (pad.A) { /* bottom button (Xbox A / PS X) */ }
    if (pad.B) { /* right button (Xbox B / PS Circle) */ }
    if (pad.X) { /* left button (Xbox X / PS Square) */ }
    if (pad.Y) { /* top button (Xbox Y / PS Triangle) */ }

    // Shoulder buttons (float 0-1)
    if (pad.L1 > 0) { /* left shoulder top (LB) */ }
    if (pad.L2 > 0) { /* left shoulder bottom / trigger (LT) */ }
    if (pad.R1 > 0) { /* right shoulder top (RB) */ }
    if (pad.R2 > 0) { /* right shoulder bottom / trigger (RT) */ }

    // Analog sticks (Vector2, values -1 to 1)
    const lx = pad.leftStick.x;  // left stick horizontal
    const ly = pad.leftStick.y;  // left stick vertical
    const rx = pad.rightStick.x;
    const ry = pad.rightStick.y;

    // Raw axis/button access
    pad.getAxisValue(0);    // float
    pad.getButtonValue(0);  // float 0-1
    pad.isButtonDown(0);    // boolean
    pad.setAxisThreshold(0.1); // ignore values below threshold
}
```

**Gamepad events:**

```js
// Plugin-level events (any gamepad)
this.input.gamepad.on('connected', (pad, event) => { /* ... */ });
this.input.gamepad.on('disconnected', (pad, event) => { /* ... */ });
this.input.gamepad.on('down', (pad, button, value) => { /* any button on any pad */ });
this.input.gamepad.on('up', (pad, button, value) => { /* ... */ });

// Gamepad-instance events
pad.on('down', (index, value, button) => { /* button on this specific pad */ });
pad.on('up', (index, value, button) => { /* ... */ });
```

**Vibration (experimental, hardware/browser dependent):**

```js
if (pad.vibration) {
    pad.vibration.playEffect('dual-rumble', {
        duration: 200,
        strongMagnitude: 1.0,
        weakMagnitude: 0.5
    });
}
```

### Key Combos

Listen for a sequence of keys:

```js
// String-based combo
this.input.keyboard.createCombo('PHASER');

// Array of key codes (Konami code)
this.input.keyboard.createCombo(
    [ 38, 38, 40, 40, 37, 39, 37, 39, 66, 65, 13 ],
    { resetOnMatch: true }
);

// Listen for match
this.input.keyboard.on('keycombomatch', (keyCombo, event) => {
    console.log('Combo matched!');
});
```

**createCombo(keys, config):**
- `keys`: a string (each character is a key) or an array of key codes / Key objects
- `config.resetOnWrongKey` (boolean, default true) - reset progress if wrong key is pressed
- `config.maxKeyDelay` (number, default 0) - max ms between key presses; 0 = no limit
- `config.resetOnMatch` (boolean, default false) - reset combo after a successful match
- `config.deleteOnMatch` (boolean, default false) - remove combo after first match
