Cocos2d-JS提供了很多特效，这些特效事实上属于间隔动作，特效类cc.GridAction类，也称为网格动作，它的类图如下图所示。
ctor: function (flagTag) {
this._super();
this.flagTag = flagTag;
this.gridNodeTarget = cc.NodeGrid.create(); ①
this.addChild(this.gridNodeTarget);
cc.log("MyActionLayer init flagTag " + this.flagTag);
var size = cc.director.getWinSize();
var bg = new cc.Sprite(res.Background_png);
bg.x = size.width / 2;
bg.y = size.height / 2;
this.gridNodeTarget.addChild(bg);
var sprite = new cc.Sprite(res.hero_png);
sprite.x = size.width / 2;
sprite.y = size.height / 2;
this.gridNodeTarget.addChild(sprite, 1, SP_TAG);
var backMenuItem = new cc.MenuItemImage(res.Back_up_png, res.Back_down_png,
function () {
cc.director.popScene();
}, this);
backMenuItem.x = 140;
backMenuItem.y = size.height - 65;
var goMenuItem = new cc.MenuItemImage(res.Go_up_png, res.Go_down_png,
this.onMenuCallback, this);
goMenuItem.x = 820;
goMenuItem.y = size.height - 540;
var mn = new cc.Menu(backMenuItem, goMenuItem);
this.gridNodeTarget.addChild(mn, 1);
mn.x = 0;
mn.y = 0;
mn.anchorX = 0.5;
mn.anchorY = 0.5;
return true;
}上述代码第①行是创建NodeGrid类型成员变量gridNodeTarget，NodeGrid是网格动作管理类。MyActionScene.js中的onMenuCallback函数代码如下： onMenuCallback: function (sender) {
cc.log("Tag = " + this.flagTag);
var size = cc.director.getWinSize();
switch (this.flagTag) {
case ActionTypes.kFlipX3D:
this.gridNodeTarget.runAction(cc.flipX3D(3.0)); ①
break;
case ActionTypes.kPageTurn3D:
this.gridNodeTarget.runAction(cc.pageTurn3D(3.0, cc.size(15, 10))); ②
break;
case ActionTypes.kLens3D:
this.gridNodeTarget.runAction(cc.lens3D(3.0, cc.size(15, 10),
cc.p(size.width / 2, size.height / 2), 240)); ③
break;
case ActionTypes.kShaky3D:
this.gridNodeTarget.runAction(cc.shaky3D(3.0, cc.size(15, 10), 5, false)); ④
break;
case ActionTypes.kWaves3D:
this.gridNodeTarget.runAction(cc.waves3D(3.0, cc.size(15, 10), 5, 40)); ⑤
break;
case ActionTypes.kJumpTiles3D:
this.gridNodeTarget.runAction(cc.jumpTiles3D(3.0, cc.size(15, 10), 2, 30)); ⑥
break;
case ActionTypes.kShakyTiles3D:
this.gridNodeTarget.runAction(cc.shakyTiles3D(3.0, cc.size(16, 12), 5, false));⑦
break;
case ActionTypes.kWavesTiles3D:
this.gridNodeTarget.runAction(cc.wavesTiles3D(3.0, cc.size(15, 10), 4, 120)); ⑧
break;
}
}第⑧行是使用WavesTiles3D实现3D瓦片波动特效，cc.wavesTiles3D函数第一个参数是持续时间，第二个参数是网格的大小，第三个参数动次数，第四个参数是振幅。
