扫雷07 游戏逻辑设计
这才是这里最重要的，整个游戏这里的代码是最关键的。
查看这个游戏的相关函数调用
在GameScene这个类中，相关的调用如下。
NoAroundMine函数
NoAroundMine函数的作用是在点击的区域满足以下三个条件的时候被调用
1、 没有被挖开
2、 不是去标记（插旗）
3、 其代笔的是周围没有雷（属性值为0）
当我们点击到属性值为0的区块的时候，说明这个位置周围没有雷。这个函数的作用就是将这个区块周围没有雷的区块都照出来。这是一个递归调用的函数
1: ///////////////////////////////////////////////////////////////////
2: // 周边无雷块的连带显示
3: void GameScene::NoAroundMine(int row,int col,CCArray * arr)
4: {
5: if (row == 0 || col == 0 || row == _MaxRanks + 1 || col == _MaxRanks + 1) {
6: return; //不需要设置的位置
7: }
8: MineBlock * mb = getRowColAddr(row,col);
9: if (mb->getValue() == -1 || mb->getDig()) {
10: return; //是雷或者被挖开，直接返回退出
11: }
12:
13:
14: //CCLog("row = %d col = %d ",row,col);
15: // 此处有问题，为何不可以获取？
16: //CCTexture2D * texture = CCTextureCache::sharedTextureCache()->textureForKey("0.png");
17:
18: // 设置当前的纹理
19: //getRowColAddr(row,col)->setTexture(CCTextureCache::sharedTextureCache()->textureForKey("0.png"));
20:
21: arr->addObject(mb);
22: mb->setDig(true);
23: if (mb->getValue() != 0) {
24: return; //不是0，不再继续
25: }
26: //getRowColAddr(row,col)->setValue(-2); //方便终止递归
27: //设置四周纹理

ContinueGame函数
ContinueGame函数是判断是否继续游戏的函数，其作用是在游戏的过程中判断输赢。
如果踩到雷或者全部非雷区都找到的话就返回false，告诉callTouchEnded游戏不再继续。否则返回true，游戏继续。
当游戏不再继续的时候，这个函数负责根据输赢显示背景或者动画。
1: ///////////////////////////////////////////////////////////////
2: // 游戏输赢判断，是否继续游戏
3: bool GameScene::ContinueGame()
5: if (_count == -1) {
6: LabelTTF* ttf = LabelTTF::create("Your fail!","Felt",WinWidth / 10);
7: _bgland->setZOrder(100);
8: _bgland->addChild(ttf);
9: ttf->setPosition(Vec2(WinWidth / 3,50));
10: ttf->setColor(ccc3(255,0));
11:
12: return false;
13: }

32: _bgland->setScale(_bgland->getBoundingBox().size.height / texture1->getContentSize().height);
33: return false; //胜利了
34: }
35: return true;
36: }
callTouchEnden函数
这个函数负责判断点击到了什么样的雷块
1: // Touch 判断点击的位置以及更新图片
2: void GameScene::callTouchEnded(Touch * pTouch,Event * pEvent)
3: {
4: Point pt = pTouch->getLocation();

11: //如果点击的这个像素不在这个精灵所在的矩形范围内
12: if (!mb->boundingBox().intersectsRect(CCRectMake(pt.x,pt.y,1,1))) {
13: continue; // 下一个
14: }
15: // 点击的位置在这个精灵的范围之内
16: if (mb->getDig()) {
17: return; //已经被挖开
18: }

24: mb->setTexture(CCTextureCache::getInstance()->getTextureForKey(ptx));
