今天写了 cocos2d-x事件EventListenerTouchOneByOne，发现死活没反应，原代码复制到新工程没问题啊， 后来发现cocostudio用的基础容器(ccui.Layout:create())默认是可交互性的，导出lua发现setTouchEnabled(true); 设置可触摸是true,这就明了拉，是Layout(继承Widget)挡住了事件下发了，按照cocos2d-x事件的原理看了C++源码，发现:
void Widget::setTouchEnabled(bool enable) { if (enable == _touchEnabled) { return; } _touchEnabled = enable; if (_touchEnabled) { _touchListener = EventListenerTouchOneByOne::create(); CC_SAFE_RETAIN(_touchListener); _touchListener->setSwallowTouches(true); _touchListener->onTouchBegan = CC_CALLBACK_2(Widget::onTouchBegan, this); _touchListener->onTouchMoved = CC_CALLBACK_2(Widget::onTouchMoved, this); _touchListener->onTouchEnded = CC_CALLBACK_2(Widget::onTouchEnded, this); _touchListener->onTouchCancelled = CC_CALLBACK_2(Widget::onTouchCancelled, this); _eventDispatcher->addEventListenerWithSceneGraphPriority(_touchListener, this); } else { _eventDispatcher->removeEventListener(_touchListener); CC_SAFE_RELEASE_NULL(_touchListener); } }
_touchListener->setSwallowTouches(true); 这句说明了一切。cocos2d-x事件EventListenerTouchOneByOne没反应
