十 手游開發神器 cocos2d-x editor 之觸摸事件

這一節 我將實現讓小怪物跟隨我的觸摸方向移動，同時觸摸的地方產生一個四周發散的效果

效果如下：

打開MainLayer.js,把onDidLoadFromCCB函數修改如下，讓觸摸可用；

MainLayer.prototype.onDidLoadFromCCB = function () {     if (sys.platform == 'browser') {         this.onEnter();     }     else {         this.rootNode.onEnter = function () {             this.controller.onEnter();         };     }      this.rootNode.schedule(function (dt) {         this.controller.onUpdate(dt);     });      this.rootNode.onExit = function () {         this.controller.onExit();     };      this.rootNode.onTouchesBegan = function (touches, event) {         this.controller.onTouchesBegan(touches, event);         return true;     };      this.rootNode.onTouchesMoved = function (touches, event) {         this.controller.onTouchesMoved(touches, event);         return true;     };     this.rootNode.onTouchesEnded = function (touches, event) {         this.controller.onTouchesEnded(touches, event);         return true;     };     this.rootNode.setTouchEnabled(true); };

MainLayer.prototype.onTouchesBegan = function (touches, event) {     var loc = touches[0].getLocation(); }  MainLayer.prototype.onTouchesMoved = function (touches, event) {     cc.log("onTouchesMoved"); }  MainLayer.prototype.onTouchesEnded = function (touches, event) {     cc.log("onTouchesEnded"); }

MainLayer.prototype.monsterMove = function (x, y) {     this.monster.stopAllActions();     cc.AnimationCache.getInstance().addAnimations("Resources/snow_frame.plist");//添加幀動畫文件     var action0 = cc.Sequence.create(cc.MoveTo.create(5, cc.p(x, y)));  //向前移動     var actionFrame = cc.Animate.create(cc.AnimationCache.getInstance().getAnimation("monster"));   //獲取幀動畫     var action1 = cc.Repeat.create(actionFrame, 90000);     var action2 = cc.Spawn.create(action0, action1); //同步動畫     this.monster.runAction(action2); }

MainLayer.prototype.onTouchesEnded = function (touches, event) {     cc.log("onTouchesEnded");     var loc = touches[0].getLocation();     this.monsterMove(loc.x, loc.y); }

再次打開MainLayer.js,加入創建粒子的函數

MainLayer.prototype.createParticle = function (name, x, y) {     var particle = cc.ParticleSystem.create("Resources/particles/" + name + ".plist");     particle.setAnchorPoint(cc.p(0.5, 0.5));     particle.setPosition(cc.p(x, y));     particle.setPositionType(1);     particle.setDuration(3);     this.rootNode.addChild(particle); }

MainLayer.prototype.onTouchesEnded = function (touches, event) {     cc.log("onTouchesEnded");     var loc = touches[0].getLocation();     this.monsterMove(loc.x, loc.y);     this.createParticle("around", loc.x, loc.y); }
