cocosCreator随笔

1.如果在程序运行当中需要修改一个图片的资源

//路径一定要放在资源管理器的绝对路径下,不然会一直报错说在resources文件下找不到
var realUrl =cc.url.raw('resources/2.png');
var texture =cc.textureCache.addImage(realUrl);
this.getComponent(cc.Sprite).spriteFrame.setTexture(texture);

//*************<方法二>**************//
cc.loader.loadRes("2",cc.SpriteFrame,function (err,spriteFrame) {
self.node.getComponent(cc.Sprite).spriteFrame = spriteFrame;
});

loadSpriteFrame(panNode, url) {
        console.log("loadSpriteFrame");
        Common.loadSpriteFrame(url, function (err, SpriteFrame) {
            if (err) {
                console.log(err);
                return;
            }
            let sp = panNode.getComponent(cc.Sprite); sp.spriteFrame = SpriteFrame; }); } export function loadSpriteFrame(url, cb) { cc.loader.loadRes(url, cc.SpriteFrame, cb); }
2.需要多个精灵执行动画，一个执行完，开始另一个执行（这里需要注意的是，执行动画的是一个线程，还有主线程，这里边一定要用一个var self =this,以免在动画线程中获取不到类的属性）

var self =this; 
var star1 = this.starlist.getChildByName('start1');
            star1.active = true;
            var action1 = cc.scaleTo(0.1, 0.4);
            var action2 = cc.scaleTo(0.1, 0.3);
            star1.runAction(cc.sequence(action1, action2,
                cc.delayTime(0.5),
                cc.callFunc(function () {
                    var star2 = self.starlist.getChildByName('start2');
                    self.loadSpriteFrame(star2,'complete/blackStar.png');
                    star2.active = true;
                    var action1 = cc.scaleTo(0.1, 0.4);
                    var action2 = cc.scaleTo(0.1, 0.3);
                    star2.runAction(cc.sequence(action1, action2));
                }),
                cc.delayTime(0.5),
                cc.callFunc(function () {
                    var star3 = self.starlist.getChildByName('start3');
                    self.loadSpriteFrame(star3,'complete/blackStar.png');
                    star3.active = true;
                    var action1 = cc.scaleTo(0.1, 0.4);
                    var action2 = cc.scaleTo(0.1, 0.3);
                    star3.runAction(cc.sequence(action1, action2));
                }),
                cc.delayTime(0.5),
                cc.callFunc(function () {
                    var star4 = self.starlist.getChildByName('start4');
                    self.loadSpriteFrame(star4,'complete/blackStar.png');
                    star4.active = true;
                    var action1 = cc.scaleTo(0.1, 0.4);
                    var action2 = cc.scaleTo(0.1, 0.3);
                    star4.runAction(cc.sequence(action1, action2));
                }),
                cc.delayTime(0.5),
                cc.callFunc(function () {
                    var star5 = self.starlist.getChildByName('start5');
                    self.loadSpriteFrame(star5,'complete/blackStar.png');
                    star5.active = true;
                    var action1 = cc.scaleTo(0.1, 0.4);
                    var action2 = cc.scaleTo(0.1, 0.3);
                    star5.runAction(cc.sequence(action1, action2));
                })
            ));

//js中的结构体

//添加触摸事件
