四、触摸处理ccTouchEnded()流程

1、获取触摸屏幕的坐标转换成地图坐标

2、推断该是否在有效范围、是否为空

3、播放触摸声音

4、依据点击坐标获取精灵、并放大1.3倍

5、依据坐标获取前一个点击的精灵

6、比較这两精灵能否够连接消除

  是。播放消除声音，清除这两坐标node。隐藏这两精灵

  否，缩小前一个精灵，并有抖动动画

7、把当前点击坐标赋值于前一个坐标. (前一坐标初始值(-1, -1))

 

//触摸结束

void MapLayer::ccTouchEnded(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)

{

CCPoint location = CCDirector::sharedDirector()->convertToGL(pTouch->getLocationInView()); //获取触摸屏幕的坐标

location = this->convertToNodeSpace(location);

//location=CCPointMake(location.x, location.y-40);

location=this->pointOfView(location);

CCLOG("x:%f",location.x);

CCLOG("y:%f",location.y);

if (this->isValiableNode(location)==false)

{

return;

}

if (this->isEmptyNode(location))

{

return;

}

SimpleAudioEngine::sharedEngine()->playEffect("12.wav"); //触摸声音

if (this->isSamePoints(location, prePoint))

{

return;

}

//点击当前精灵

CCSprite *spritecurrent=(CCSprite *)this->getChildByTag(TAG_START_SPRITE+this->indexFromPoint(location));

spritecurrent->setScale(1.3); //放大

CCLOG("%d",this->indexFromPoint(location));

if (this->isValiableNode(prePoint))

{

//前一个精灵

CCSprite *spritepre=(CCSprite *)this->getChildByTag(TAG_START_SPRITE+this->indexFromPoint(prePoint));

if (this->canClearTwo(prePoint, location)) //比較这两精灵能否够连接消除

{

SimpleAudioEngine::sharedEngine()->playEffect("4.wav");

this->clearNode(location);

this->clearNode(prePoint);

spritecurrent->setVisible(false);

spritepre->setVisible(false);

}

else

{

spritepre->setScale(0.9);

this->scaleAnimation(spritepre);

}

}

prePoint=location; //把当前点击坐标赋值于前一个坐标

}
