cocos3.x 扫雷06 触摸事件

扫雷06 触摸事件

创建触摸事件

在cocos2.2.3的时候，设置触摸比较麻烦，并不是所有控件都可以直接设置触摸事件。这里本来之前的方法是可以的用的，为了转移到3.x上来，就不用了，改用3.x的触摸对象。

 1: //创建一个单点触摸实例

 2: auto evt = EventListenerTouchOneByOne::create();

 3: evt->setEnabled(true);

 4: evt->onTouchBegan = [&](Touch * pTouch,Event * pEvent){

 5:     return this->callTouchBegan(pTouch,pEvent);

 6: };

 7: evt->onTouchEnded = [&](Touch * pTouch,monospace; width: 100%; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; border-left-style: none; line-height: 16pt; padding-right: 0px; background-color: #f4f4f4"> 8:     return this->callTouchEnded(pTouch,monospace; width: 100%; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; border-left-style: none; line-height: 16pt; padding-right: 0px; background-color: white"> 9: };

 10: _eventDispatcher->addEventListenerWithSceneGraphPriority(evt,this);

实现触摸回调函数

函数实现点击到雷区方块后显示其所代表的图片

一下代码只是简单的实现踩到对应的方块后显示对应的图片。

1: /////////////////////////////////////////////////////////////////////////

 2: // ccTouch

 3: bool GameScene::callTouchBegan(Touch * pTouch,Event * pEvent)

 4: {

 5:     return _isContinue;    //如果不再继续游戏，就不再往下传递了

 6: }

 7:

 8: // Touch 判断点击的位置以及更新图片

 9: void GameScene::callTouchEnded(Touch * pTouch,monospace; width: 100%; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; border-left-style: none; line-height: 16pt; padding-right: 0px; background-color: #f4f4f4"> 10: {

 11:     Point pt = pTouch->getLocation();

 12:

 13:     CCObject * obj;

 14:

 15:     CCARRAYDATA_FOREACH(_ArraySprite->data,obj)

 16:     {

 17:         MineBlock * mb = (MineBlock*)obj;

 18:         //如果点击的这个像素不在这个精灵所在的矩形范围内

 19:         if (!mb->boundingBox().intersectsRect(CCRectMake(pt.x,pt.y,1,1))) {

 20:             continue;    // 下一个

 21:         }

 22:         // 点击的位置在这个精灵的范围之内

 23:         if (mb->getDig()) {

 24:             return;        //已经被挖开

 25:         }

 26:         char filename[16] = { 0 };

 27:         int t = mb->getValue();

 28:         // 如果是去标记

 29:         if (_toFlag) {

 30:             const char *ptx = mb->getFlag() ? "no.png" : "flag.png";

 31:             mb->setTexture(CCTextureCache::sharedTextureCache()->textureForKey(ptx));

 32:             mb->setFlag(!mb->getFlag());

 33:             return;

 34:         }

 35:         //踩到雷------------------------------------------------------------------------

 36:         if (t == -1) {

 37:             _count = -1;    //设置计数为-1，代表输了

 38:             //显示所有雷

 39:             CCARRAYDATA_FOREACH(_ArraySprite->data,monospace; width: 100%; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; border-left-style: none; line-height: 16pt; padding-right: 0px; background-color: #f4f4f4"> 40:             {

 41:                 MineBlock * mine = (MineBlock*)obj;

 42:                 if (mine->getValue() == -1) {

 43:                     mine->setTexture(CCTextureCache::sharedTextureCache()->textureForKey("-1.png"));

 44:                 }

 45:             }

 46:             //显示爆炸

 47:             mb->setTexture(CCTextureCache::sharedTextureCache()->textureForKey("boom.png"));

 48:             goto CONTINUEGAME;    //到此结束

 49:         }    // end if t == -1

 50:

 51:         //没有踩到雷，但是周围有雷

 52:             //在移植到安卓的时候，全部精灵的_value都为0，出现错误，sprintf函数没有问题

 53:             sprintf(filename,"%d.png",t);

 54:             mb->setTexture(CCTextureCache::sharedTextureCache()->textureForKey(filename));

 55:             mb->setDig(true);

 56:             ++_count;    //扫区计数加一

 57:             goto CONTINUEGAME;    //到此结束

 58:

 59:     }    //end CCARRAYDATA_FOREACH...

 60:     CONTINUEGAME:

 61:     _isContinue=ContinueGame();

 62: }
