scene.load.scenePlugin('rexgesturesplugin', 'https://raw.githubusercontent.com/rexrainbow/phaser3-rex-notes/master/dist/rexgesturesplugin.min.js', 'rexGestures', 'rexGestures');

Add swipe input

var swipe = scene.rexGestures.add.swipe(config);
// var swipe = scene.rexGestures.add.swipe(gameObject, config);

Import plugin¶

Install rex plugins from npm
```
npm i phaser3-rex-plugins
```

Install plugin in configuration of game

import GesturesPlugin from 'phaser3-rex-plugins/plugins/gestures-plugin.js';
var config = {
    // ...
    plugins: {
        scene: [{
            key: 'rexGestures',
            plugin: GesturesPlugin,
            mapping: 'rexGestures'
        },
        // ...
        ]
    }
    // ...
};
var game = new Phaser.Game(config);

Add swipe input

var swipe = scene.rexGestures.add.swipe(config);
// var swipe = scene.rexGestures.add.swipe(gameObject, config);

Import class¶

Install rex plugins from npm
```
npm i phaser3-rex-plugins
```

Import class

import { Swipe } from 'phaser3-rex-plugins/plugins/gestures.js';

Add swipe input

var swipe = new Swipe(scene, config);
// var swipe = new Swipe(gameObject, config);

Create instance¶

Swipe input
```
var swipe = scene.rexGestures.add.swipe({
    // enable: true,
    // bounds: undefined,

    // threshold: 10,
    // velocityThreshold: 1000,
    // dir: '8dir',
});
```
- enable : Set false to disable input events.
- bounds : Touch detecting area rectangle, if game obect is not given.
  - undefined : Ignore this feature, default behavior.
- time : Max time of the pointer to be down.
- threshold : Minimal movement when pointer is down.
- velocityThreshold : Minimal dragging speed.
- dir :
  - 'up&down', or 0 : Get up or down state only.
  - 'left&right', or 1 : Get left or right state only.
  - '4dir', or 2 : Get up, down, left or right state.
  - '8dir', or 3 : Get up, up/left, up/right, down, down/left, down/right, left, or right state.

Swipe behavior of game object

var swipe = scene.rexGestures.add.swipe(gameObject, {
    // enable: true,

    // threshold: 10,
    // velocityThreshold: 1000,
    // direction: '8dir',
});

Enable¶

Get

var enable = swipe.enable;  // enable: true, or false

Set

swipe.setEnable(enable);  // enable: true, or false
// swipe.enable = enable;

Toggle
```
swipe.toggleEnable();
```

Events¶

swipe.on('swipe', function(swipe, gameObject, lastPointer){
}, scope);

swipe.left, swipe.right, swipe.up, swipe.down : Swipe direction states.
swipe.worldX, swipe.worldY : World position of swiping start.
swipe.x, swipe.y : Scene position of swiping start.
swipe.dragVelocity : Velocity of dragging.
gameObject, swipe.gameObject : Parent gameobject of this pan behavior.
lastPointer : Last touch pointer.

Is swiping¶

var isSwiping = swipe.isSwiping;

Return true if panning.

Is pointer inside another game object¶

Under any swipe event,

swipe.on('swipe', function(swipe){
    var isPointerInsideGameObject = swipe.isPointerInGameObject(anotherGameObject);
});

Other properties¶

Drag threshold

Get

var dragThreshold = swipe.dragThreshold;

Set

swipe.setDragThreshold(dragThreshold);
// swipe.dragThreshold = dragThreshold;

Velocity threshold

Get

var velocityThreshold = swipe.velocityThreshold;

Set

swipe.setVelocityThreshold(velocityThreshold);
// swipe.velocityThreshold = velocityThreshold;

Direction mode

Get

var dirMode = swipe.dirMode;  // 0,1,2,3

Set

swipe.setDirectionMode(dirMode);  // 0,1,2,3,'up&down','left&right','4dir','8dir'
// swipe.dirMode = dirMode;  // 0,1,2,3

Detect bounds

Get
```
var bounds = swipe.bounds;
```

Set

swipe.setDetectBounds(bounds);
// swipe.bounds = bounds;
