SpriteSheet

var data = {
    images: ["sprites.jpg"],
    images: [this.game.load.get('ship')]],
    frames: {width:50, height:50},
    frames: {width:64, height:64, count:20, regX: 32, regY:64, spacing:0, margin:0},
    frames: [

        [64, 0, 96, 64],
        [0, 0, 64, 64, 1, 32, 32]
        // etc.
    ],
    animations: {
        // start, end, next*, speed*
        run: [0, 8],

SpriteSheet原点(regX,regY)

在用Animate CC制作一个MovieClip元件时，可以Edit Multiple Frames，再Ctrl+A全选所有桢拖动元件到“+”号位置来改变Movie Clip的中心点（一般我们拖动“+”号到MC中心）。在Libray中，右键选中此Movie Clip从右键菜单中选择“Generate Sprite Sheet”，导出的Data数据会带上regX，regY。

export default class Ship {
  constructor (game) {
    this.game = game
    this.init()
  }

  init () {
    let data = {
      images: [this.game.load.get('ship')],
      frames: [
        // x, y, width, height, imageIndex*, regX*, regY*
        // fly,die,bubble动画所有帧的中心点都在图片的中央，如果用Sprite来设置中心点，是很难分别设各animations的regX，regY的
        [0, 0, 82, 60, 0, 41, 30],
        [0, 60, 130, 130, 0, 65, 65],
        [0, 190, 130, 130, 0, 65, 65],
        [0, 320, 130, 130, 0, 65, 65],
        [0, 450, 170, 170, 0, 86, 88]
      ],
      framerate: 5,
      animations: {
        fly: [0],
        die: [1, 3],
        bubble: [4]
      }
    }
    let spriteSheet = new createjs.SpriteSheet(data)
    this.sprite = new createjs.Sprite(spriteSheet)
    this.game.stage.addChild(this.sprite)
    this.sprite.set({ x: this.game.canvas.width / 2, y: this.game.canvas.height / 2 })
    console.info(this.sprite.regX) // sprite的regX还是为0
    this.sprite.gotoAndPlay('fly')
  }
