[cocos2d-js]長按按鈕事件

定義兩個全局變量

var bLeftButtonClick = false;
var bRightButtonClick = false;

var MainLayer = cc.Layer.extend({

 

監聽事件

var sprite1 = cc.Sprite.create(res.btn_left_up);
        sprite1.setPosition(size.width/2 - 80, size.height/2 + 80);
        this.addChild(sprite1, 10);
        var sprite2 = cc.Sprite.create(res.btn_right_up);
        sprite2.setPosition(size.width/2, size.height/2);
        this.addChild(sprite2, 20);

        // Make sprite1 touchable
        var listener1 = cc.EventListener.create({
            event: cc.EventListener.TOUCH_ONE_BY_ONE, //TOUCH_ONE_BY_ONE 為單次觸摸事件監聽器
            swallowTouches: true,
            onTouchBegan: function (touch, event) {
                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)) {
                    if (target == sprite2) {
                        bRightButtonClick = true;
                    } else if (target == sprite1) {
                        bLeftButtonClick = true;
                    }
                    // 需要返回true，否則不會調用后面的onTouchEnded方法
                    return true;
                }
                return false;
            },
            onTouchEnded: function (touch, event) {
                var target = event.getCurrentTarget();
                if (target == sprite2) {
                    bRightButtonClick = false;
                } else if (target == sprite1) {
                    bLeftButtonClick = false;
                }
            }
        });

        cc.eventManager.addListener(listener1, sprite1);
        cc.eventManager.addListener(listener1.clone(), sprite2);

在每幀刷新事件里面處理

// 定時任務
    update:function (dt) {
        this._ball.update(dt);
        this.checkIsCollide();
        if (bLeftButtonClick)
        {
            this._man.runLeft(dt);
        }
        else if (bRightButtonClick)
        {
            this._man.runRight(dt);
        }
    },
