cocos2d-x项目101次相遇:3.0 的点击事件，CCTouchDelegate已经停用了

cocos2d-x 101次相遇 / 目录
1 安装和环境搭建 －xcode
2 Scenes ， Director， Layers， Sprites
3 建立图片菜单
4 在HelloWorld上－－建立新场景
5 增加一个精灵sprite
5.1 缩小sprite并使之完整显示
6 action ,移动sprite
7 3.0 的点击事件，CCTouchDelegate已经停用了
8 使用触摸事件移动 精灵

cocos2d-x 3.0 不再使用 TouchDelegate方式来将touch事件捆绑到sprite上。新的方法是

auto listener =EventListenerTouchOneByOne::create();

listener->setSwallowTouches(true);

listener->onTouchBegan = CC_CALLBACK_2(CMyFirstScene::onTouchBegan,this);

listener->onTouchMoved = CC_CALLBACK_2(CMyFirstScene::onTouchMoved,this);

listener->onTouchEnded = CC_CALLBACK_2(CMyFirstScene::onTouchEnded,this);

_eventDispatcher->addEventListenerWithSceneGraphPriority(listener,this);

这段代码可以放在.cpp里面的 init里。头文件增加：

Sprite*s;

// 初始化

bool onTouchBegan(Touch* touch,Event*event);

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

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

void selectSpriteForTouch(Point touchLocation);

s 为全局的精灵。

boolCMyFirstScene::onTouchBegan(Touch* touch,Event*event)

{

CCLOG("TouchBegan");

Point touchLocation =this->convertTouchToNodeSpace(touch);

this->selectSpriteForTouch(touchLocation);

returntrue;

}

voidCMyFirstScene::onTouchMoved(Touch* touch,Event*event)

{

CCLOG("TouchMoved");

}

voidCMyFirstScene::onTouchEnded(Touch* touch,Event*event)

{

CCLOG("TouchEnded");

}

voidCMyFirstScene::selectSpriteForTouch(Point touchLocation)

{

if(s->getBoundingBox().containsPoint(touchLocation))

{

Action* actionMove =

MoveTo::create(2.0,

ccp(300,200));

s->runAction(actionMove);

}

}

这段代码，点击到精灵，精灵就会移动。
