拼图游戏的艺术

拼图游戏在今天下午也是完美结束，上午产生的 图碎片没锁定效果以及 拼图完毕却不能结束游戏的代码更正完毕。

下午同时也优化了拼图游戏的代码，以及拼图游戏中碎片的位置也在了它们该在的地方，下面是碎片精灵的类属性小段代码：

var Debris = cc.Sprite.extend({
        //坐标
        _targetPoint: null,
        //是否可以拖动
        reachTarget: null,
        //回调方法
        _callHandler: null,
        //圆片 切割区域 以及移动的目标地点
        ctor:function(texture, rect, targetPoint, callHandler){
                this._super(texture, rect);
                this._targetPoint = targetPoint;
                this._callHandler = callHandler;
                this._init();
                this._addEvent();
        },
        /*
        初始化
         */
        _init:function(){
                this.reachTarget = false;
                this.anchorX = 0;
                this.anchorY = 1;
                this.x = 1600 + Math.random()*250;
                this.y = 235 + Math.random()*500;
        },
        /*添加点击事件*/
        _addEvent:function(){
                var that = this;
                var listener = cc.EventListener.create({
                        event:cc.EventListener.TOUCH_ONE_BY_ONE,
                        swallowTouches: true,
                        onTouchBegan:function(touch, event){
                                if(that.reachTarget) return false;
                                var target = event.getCurrentTarget();
                                var locationInNode = target.convertToNodeSpace(touch.getLocation());
                                var s = target.getContentSize();
                                var rect = cc.rect(0,0, s.width, s.height);
                                if(cc.rectContainsPoint(rect,locationInNode)){
                                        target.setZOrder(10);
                                        return true;
                                }
                                return false;
                        },
                        onTouchMoved:function(touch, event){
                                var target = event.getCurrentTarget();
                                var delta = touch.getDelta();
                                target.x += delta.x;
                                target.y += delta.y;
                        },
                        onTouchEnded:function(touch, event){
                                var target = event.getCurrentTarget();
                                if(cc.pDistance(target.getPosition(), that._targetPoint)<50){
                                        target.setPosition(that._targetPoint);
                                        that.reachTarget = true;
                                        that._callHandler();
                                }
                        }
                });
                cc.eventManager.addListener(listener, this);
        }


});

       终于结束了一周的忙碌能休息一会了~
