c++ - 点击不起作用

Question

我有什么错？HelloWorldScene.h中有一个方法

 void onTouchEnded(Touch *touch,Event *event);

文件HelloWorldScene.cpp我在Init()方法中写了

this->setTouchEnabled(true);

这里是方法的描述

void HelloWorld::onTouchEnded(Touch *touch,Event *event)
{
    CCPoint location = touch->getLocationInView();

    location = CCDirector::sharedDirector()->convertToGL(location);
    location = this->convertToNodeSpace(location);

    CCLog("x =  %f \n y =  %f \n ---------------------",location.x,location.y);
}

但是点击Windows失败

Touch Event有两种----TargetedDelegate和StandardDelegate

针对目标委托(delegate)

virtual void registerWithTouchDispatcher();  
virtual bool ccTouchBegan (CCTouch *pTouch, CCEvent *pEvent);
virtual void ccTouchMoved (CCTouch *pTouch, CCEvent *pEvent);
virtual void ccTouchEnded (CCTouch *pTouch, CCEvent *pEvent);

在你的 init() 中:

this->setTouchEnabled(true);

并重写registerWithTouchDispatcher()

void Layer::registerWithTouchDispatcher(){
    CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(this,0,true);
}

对于标准代理

 virtual void ccTouchesBegan (CCSet *pTouches, CCEvent *pEvent);
 virtual void ccTouchesMoved (CCSet *pTouches, CCEvent *pEvent);
 virtual void ccTouchesEnded (CCSet *pTouches, CCEvent *pEvent);

在你的 init() 中:

this->setTouchEnabled(true);

如果在这里重写registerWithTouchDispatcher()。您应该在 init() 中调用 addStandardDelegate()。

CCDirector::sharedDirector()->getTouchDispatcher()->addStandardDelegate(this,0);
