pixi-simple-gesture

Add Pinch, Pan, Tap gesture support to pixi.js sprites.

npm install --save pixi-simple-gesture

Usage

Pinch

var gesture = require('pixi-simple-gesture')

var sprite = new PIXI.Sprite(texture)
var inertiaMode = true

gesture.pinchable(sprite, inertiaMode)

sprite.on('pinchstart', function() {
  console.log('pinch start')
})

sprite.on('pinchmove', function(event) {
  console.log('pinch move', event)
})

sprite.on('pinchend', function() {
  console.log('pinch end')
})

The 'pinchmove' handler receives an event object containing the following properties.

Name	Value
scale	Scaling that has been done
velocity	Velocity in px/ms
center	Center position for multi-touch
data	Original InteractionData from pixi.js

Pan

var gesture = require('pixi-simple-gesture')
var inertiaMode = true

var sprite = new PIXI.Sprite(texture)
gesture.panable(sprite, inertiaMode)

sprite.on('panstart', function() {
  console.log('pan start')
})

sprite.on('panmove', function(event) {
  console.log('pan move', event)
})

sprite.on('panend', function() {
  console.log('pan end')
})

The 'panmove' handler receives an event object containing the following properties.

Name	Value
deltaX	Movement of the X axis
deltaY	Movement of the Y axis
velocity	Velocity in px/ms
data	Original InteractionData from pixi.js

Tap

var gesture = require('pixi-simple-gesture')

var sprite = new PIXI.Sprite(texture)
gesture.tappable(sprite)

sprite.on('simpletap', function() {
  console.log('simply tapped')
})

NOT 'tap', simpletap. Because 'tap' is already used by pixi.js. This 'simpletap' works a bit better with 'pinch' and 'pan'. The Handler receives an event object containing the following properties.

Name	Value
data	Original InteractionData from pixi.js

Note

Any requests, issues, PRs are welcome!

TODO

• Add Inertia Mode
• Add Complex? Tap, emits 'tapstart', 'tapcancel', 'tapend'. Could be useful to implement UI components which has active state style.
