代码例子

1.小球不断上下跳动

cc.Class({
    extends: cc.Component,
 
    properties: {
       jumpDuration:2,
       jumpHeight:300
    },
    ballJumpAction:function(){
        //向上跳动
        var jumpUp = cc.moveBy(this.jumpDuration,cc.p(0,this.jumpHeight)).easing(cc.easeCubicActionOut());
        //下落
        var jumpDown = cc.moveBy(this.jumpDuration,cc.p(0,-this.jumpHeight)).easing(cc.easeCubicActionIn());
        //不断重复
        return cc.repeatForever(cc.sequence(jumpUp ,jumpDown));
 
    },
    // use this for initialization
    onLoad: function () {
        this.jumpAction = this.ballJumpAction();
        this.node.runAction(this.jumpAction);
    },
 
    // called every frame, uncomment this function to activate update callback
    // update: function (dt) {
 
    // },
});

2.场景切换、倒计时

场景切换：

onLoad: function () {
        this.node.on('mousedown',function(){
            cc.director.loadScene('Scene2');
        })
    },

倒计时自动转换场景

//直接拖至画布上
cc.Class({
    extends: cc.Component,
 
    properties: {
       timeLabel:{
           default:null,
           type:cc.Label
       }
    },
 
    // use this for initialization
    onLoad: function () {
        var timeIn=5;
        this.schedule(function(){
            timeIn--;
            this.time_Label.string=timeIn;
            if(timeIn===0){
                cc.director.loadScene('Scene3');
            }
        },1);
    },
 
    // called every frame, uncomment this function to activate update callback
    // update: function (dt) {
 
    // },
});

3.输入事件监听操作

// 键盘控制飞机移动ASWD控制；js挂到飞机(图片)上
cc.Class({
    extends: cc.Component,
    properties: {
        accl:0,
        plane:{
            default:null,
            type:cc.Node
        }
    },
    setInputControl:function(){
        var self = this;
        var listener= {
            event:cc.EventListener.KEYBOARD,
            onKeyPressed:function(keyCode,event){
                switch(keyCode){
                    case cc.KEY.a:
                        self.accLeft= true;
                        break;
                    case cc.KEY.d:
                        self.accRight= true;
                        break;
                    case cc.KEY.w:
                        self.accUp= true;
                        break;
                    case cc.KEY.s:
                        self.accDown= true;
                        break;
                }
            },
            onKeyReleased:function(keyCode,event){
                switch(keyCode){
                    case cc.KEY.a:
                        self.accLeft= false;
                        break;
                    case cc.KEY.d:
                        self.accRight= false;
                        break;
                    case cc.KEY.w:
                        self.accUp= false;
                        break;
                    case cc.KEY.s:
                        self.accDown= false;
                        break;
                }
            }
        }
        cc.eventManager.addListener(listener, self.node)
    },
 
    // use this for initialization
    onLoad: function () {
        this.accLeft = false;
        this.accRight = false;
        this.accUp = false;
        this.accDoen = false;
        this.setInputControl();
    },
 
    // called every frame, uncomment this function to activate update callback
    update: function (dt) {
        if(this.accLeft){
            this.plane.x -=this.accl;
        }
        if(this.accRight){
            this.plane.x +=this.accl;
        }
        if(this.accUp){
            this.plane.y +=this.accl;
        }
        if(this.accDown){
            this.plane.y -=this.accl;
        }
     },
});
