前端之家收集整理的这篇文章主要介绍了
cocos2dx屏蔽层的制作，防止当前层点击上一层。，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
#ifndef _ShieldLayer_H_
#define _ShieldLayer_H_
#include "cocos2d.h"
USING_NS_CC;
//////////////////////////////////////////////////////////////////////////
//屏蔽层
class ShieldLayer: public Layer
{
public:
CREATE_FUNC(ShieldLayer);
private:
ShieldLayer() {}
~ShieldLayer() {
mListener->release();
}
bool init()
{
do
{
CC_BREAK_IF(!Layer::init());
mListener = EventListenerTouchOneByOne::create();//创建一个触摸监听
mListener->onTouchBegan = [](Touch* touch,Event* event) {
log("ShieldLayer");
return true;
};
//mListener->onTouchMoved = [](Touch* touch,Event* event){};
//mListener->onTouchEnded = [](Touch* touch,Event* event){};
mListener->setSwallowTouches(true);
mListener->retain();
setTouchEnabled(true);
return true;
} while (0);
return false;
}
public:
void setTouchEnabled(bool value)
{
if (value) {
_eventDispatcher->removeEventListener(mListener);
_eventDispatcher->addEventListenerWithSceneGraPHPriority(mListener,this);
}
else
{
_eventDispatcher->removeEventListener(mListener);
}
}
private:
EventListenerTouchOneByOne* mListener;
};
#endif // _ShieldLayer_H_
只要在当前层上创建该屏蔽层，就可以防止点击到上一层页面。
