EventManager

1. 创建监听器

var listener = cc.EventListener.create({
            event: cc.EventListener.TOUCH_ONE_BY_ONE,
            swallowTouches: true,
            onTouchBegan: function (touch, event) {
                var locationInNode = selfPointer.convertToNodeSpace(touch.getLocation());
                var s = selfPointer.getContentSize();
                var rect = cc.rect(0, 0, s.width, s.height);

                if (cc.rectContainsPoint(rect, locationInNode)) {
                    selfPointer.setColor(cc.color.RED);
                    return true;
                }
                return false;
            },
            onTouchMoved: function (touch, event) {
                //this.setPosition(this.getPosition() + touch.getDelta());
            },
            onTouchEnded: function (touch, event) {
                selfPointer.setColor(cc.color.WHITE);
                if(selfPointer._removeListenerOnTouchEnded)
                    cc.eventManager.removeListener(selfPointer._listener);
            }
        });

2. 加入监听器

cc.eventManager.addListener(listener, this);

3. ToggleMenuItem加入监听以及移除监听

  var toggleItem = cc.MenuItemToggle.create(cc.MenuItemFont.create("Enabled"), cc.MenuItemFont.create("Disabled"),
            function (sender) {
                if (enable) {
                    cc.eventManager.removeListener(listener1);
                    statusLabel.setString("The sprite could not be touched!");
                    enable = false;
                } else {
                    cc.eventManager.addListener(listener1, sprite1);
                    statusLabel.setString("The sprite could be touched!");
                    enable = true;
                }
            });

        toggleItem.setPosition(origin.x + size.width/2, origin.y + 80);
        var menu = cc.Menu.create(toggleItem);
        menu.setPosition(0, 0);
        menu.setAnchorPoint(0, 0);
        this.addChild(menu, 1);

4.自定义事件

  this._listener1 = cc.EventListener.create({
            event: cc.EventListener.CUSTOM,
            eventName: "game_custom_event1",
            callback: function(event){
                statusLabel.setString("Custom event 1 received, " + event.getUserData() + " times");
            }
        });
        cc.eventManager.addListener(this._listener1, 1);

        var sendItem = cc.MenuItemFont.create("Send Custom Event 1", function(sender){
            ++selfPointer._item1Count;
            var event = new cc.EventCustom("game_custom_event1");
            event.setUserData(selfPointer._item1Count.toString());
            cc.eventManager.dispatchEvent(event);
        });
        sendItem.setPosition(origin.x + size.width/2, origin.y + size.height/2);

5.键盘事件

  cc.eventManager.addListener({
            event: cc.EventListener.KEYBOARD,
            onKeyPressed:  function(keyCode, event){
                var label = event.getCurrentTarget();
                label.setString("Key " + String.fromCharCode(keyCode) + "(" + keyCode.toString()  + ") was pressed!");
            },
            onKeyReleased: function(keyCode, event){
                var label = event.getCurrentTarget();
                label.setString("Key " + String.fromCharCode(keyCode) + "(" + keyCode.toString()  + ") was released!");
            }
        }, statusLabel);

6.加速事件

cc.eventManager.addListener({
            event: cc.EventListener.ACCELERATION,
            callback: function(acc, event){
                var target = event.getCurrentTarget();
                var ballSize  = target.getContentSize();
                var ptNow  = target.getPosition();

                //cc.log("acc: x = " + acc.x + ", y = " + acc.y);

                target.x = SpriteAccelerationEventTest._fix_pos(ptNow.x + acc.x * 9.81,
                    (cc.visibleRect.left.x + ballSize.width / 2.0), (cc.visibleRect.right.x - ballSize.width / 2.0));
                target.y = SpriteAccelerationEventTest._fix_pos(ptNow.y + acc.y * 9.81,
                    (cc.visibleRect.bottom.y + ballSize.height / 2.0), (cc.visibleRect.top.y - ballSize.height / 2.0));
            }
        }, sprite);

7.回调函数

 this.runAction(cc.Sequence.create(cc.DelayTime.create(5.0),
            cc.CallFunc.create(function () {
                this._spriteSaved = true;
                this._sprite.retain();
                this._sprite.removeFromParent();
            }, this),
            cc.DelayTime.create(5.0),
            cc.CallFunc.create(function () {
                this._spriteSaved = false;
                this.addChild(this._sprite);
                if(!cc.sys.isNative)
                    cc.eventManager.addListener(listener1, this._sprite);
                this._sprite.release();
            }, this)
        ));

8.面向切面

this._event1 = dispatcher.addCustomListener(cc.Director.EVENT_AFTER_UPDATE, this.onEvent1.bind(this));
        this._event2 = dispatcher.addCustomListener(cc.Director.EVENT_AFTER_VISIT, this.onEvent2.bind(this));
        this._event3 = dispatcher.addCustomListener(cc.Director.EVENT_AFTER_DRAW, function(event) {
            selfPointer._label3.setString("Draw: " + selfPointer._count3++);
        });
        this._event4 = dispatcher.addCustomListener(cc.Director.EVENT_PROJECTION_CHANGED, function(event) {
            selfPointer._label4.setString("Projection: " + selfPointer._count4++);
        });

9.移除监听

   cc.eventManager.removeListeners(cc.EventListener.TOUCH_ONE_BY_ONE);
