Cocos2dx制作2048(3.数字相加逻辑)

2024-07-09 19:36:10 223人阅读

这次我们来完成整个2048的数字相加逻辑其实2048玩起来简单，做起来也简单，复杂就复杂在这整个游戏的逻辑。

1.分析向左滑动

第一轮相加步骤:
1. 单1+单2 单1=2 单2赋值为0 (单1为空，可以加任何数字)
2. 单1+单3 单1=4 单3赋值为0 （单1不为空，只能加和他相同的数字）
3. 单1+单4 单1=4 单4不变 (单1不为空，只能加和他相同的数字)

第二轮相加步骤:

1. 单2+单3 单2=0 单3不变（单2为0可以加任何数字，但是单3也是0,,其实加不加都是一个效果）

2. 单2+单4 单2=2 单4赋值0 （单2为0可以加任何数字）

接着就是单3加单4了，这两个都为空，什么都不做，最终的效果也就是，第二轮相加后的效果了

这个其实就是用的冒泡算法，好了，理解了之后，那么我们来写代码。

首先,我们在初始化矩阵中给所有的数字方块初始化为2，暂时先注释掉随机创建的方法

void HelloWorld::initMatrix(CCSize size)
{
	//两个方块之间的空隙
	int space=10;
	int SquareSize=(size.width-space*5)/4;
	for (int x = 0; x < 4; x++)
	{
		for (int y = 0; y < 4; y++)
		{
			float pointx=space+x*SquareSize+x*space;
			float pointy=40+y*SquareSize+y*space;
			SquareSprite* pSquareSprite=SquareSprite::createSquareSprite(2,pointx,pointy,SquareSize,SquareSize);
			this->addChild(pSquareSprite,1);
			m_squarearray[x][y]=pSquareSprite;
		}
	}
	/*
	//刚开始游戏，创建两个方块
	autoSquare();
	autoSquare();
	*/
}

OK，向左滑动，那么此时我们需要在doLeft方法中写代码咯

bool HelloWorld::doLeft()
{
	for (int y = 0; y < 4; y++)
	{
		for (int x = 0; x < 4; x++)
		{
			for (int afterx = x+1; afterx < 4; afterx++)
			{

			}
		}
	}
	return true;
}

大概的框架就是这样子吧？？最外层的y我们可以忽视，这是左加不是上下加

里面两个循环表示什么呢？？x=0时 afterx=1 即单1和单2 依次类推

OK，我们在循环中写代码，

bool HelloWorld::doLeft()
{
	for (int y = 0; y < 4; y++)
	{
		for (int x = 0; x < 4; x++)
		{
			for (int afterx = x+1; afterx < 4; afterx++)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[afterx][y]->getNumber());
					m_squarearray[afterx][y]->setNumber(0);
				}
				else if (m_squarearray[afterx][y]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[afterx][y]->setNumber(0);
				}
			}
		}
	}
	return true;
}

这里有两种情况，

1.单1等于0时，不管单2是什么，都要和单2调换位置

2.单1不等于0时，那么只有单1和单2相等，才能相加

大家可以运行看看效果。

2.分析向右滑动

这里和向左滑动差不多，其实就是一个是顺着来一个是倒着来，我就不画图了，直接上代码

bool HelloWorld::doReight()
{
	for (int y = 0; y < 4; y++)
	{
		for (int x = 3; x >=0; x--)
		{
			for (int afterx = x-1; afterx >=0; afterx--)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[afterx][y]->getNumber());
					m_squarearray[afterx][y]->setNumber(0);
				}
				else if (m_squarearray[afterx][y]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[afterx][y]->setNumber(0);
				}
			}
		}
	}
	return true;
}

其他地方都没改，就把两个循环改了一下

3.分析向上滑动

bool HelloWorld::doTop()
{
	for (int x = 0; x < 4; x++)
	{
		for (int y = 3; y >=0; y--)
		{
			for (int aftery = y-1; aftery >=0; aftery--)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][aftery]->getNumber());
					m_squarearray[x][aftery]->setNumber(0);
				}
				else if (m_squarearray[x][aftery]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[x][aftery]->setNumber(0);
				}
			}
		}
	}
	return true;
}

4.分析向下滑动

bool HelloWorld::doDown()
{
	for (int x = 0; x < 4; x++)
	{
		for (int y = 0; y <4; y++)
		{
			for (int aftery = y+1; aftery <4; aftery++)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][aftery]->getNumber());
					m_squarearray[x][aftery]->setNumber(0);
				}
				else if (m_squarearray[x][aftery]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[x][aftery]->setNumber(0);
				}
			}
		}
	}
	return true;
}

现在基本上成了，那么我再修改其他几个函数，

首先把初始化矩阵的方法还原

void HelloWorld::initMatrix(CCSize size)
{
	//两个方块之间的空隙
	int space=10;
	int SquareSize=(size.width-space*5)/4;
	for (int x = 0; x < 4; x++)
	{
		for (int y = 0; y < 4; y++)
		{
			float pointx=space+x*SquareSize+x*space;
			float pointy=40+y*SquareSize+y*space;
			SquareSprite* pSquareSprite=SquareSprite::createSquareSprite(0,pointx,pointy,SquareSize,SquareSize);
			this->addChild(pSquareSprite,1);
			m_squarearray[x][y]=pSquareSprite;
		}
	}
	//刚开始游戏，创建两个方块
	autoSquare();
	autoSquare();
}

然后，不管用户向那个方向滑动，只要是滑动了，就都得产生一个数字方块

void HelloWorld::ccTouchEnded(CCTouch *pTouch, CCEvent *pEvent)
{
	bool isTouch=false;
	CCPoint point=	pTouch->getLocation();
	m_RangeX=m_StartX-point.x;
	m_RangeY=m_StartY-point.y;

	if (abs(m_RangeX)>abs(m_RangeY))
	{
		//X大于Y	左右移动
		if (m_RangeX>5)
		{
			//正数	向左
			isTouch=doLeft();
		}
		else  if(m_RangeX<-5)
		{
			//负数	向右
			isTouch=doReight();
		}
	}
	else
	{
		//否则	上下移动
		if (m_RangeY>5)
		{
			//正数	向下
			isTouch=doDown();
		}
		else  if(m_RangeY<-5)
		{
			//负数	向上
			isTouch=doTop();
		}
	}
	if (isTouch)
	{
		autoSquare();
	}
}

测试一下，貌似我有发现了一个BUG

结合我们的代码分析一下也确实是这种情况，那么怎么破呢？？

应该在两个同等数字相加后，就Brack，不能再继续加下去了

else if (m_squarearray[x][aftery]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[x][aftery]->setNumber(0);
					break;
				}

刚测试，又发现一个BUG

本来是 4 2 4 0

向右滑动应该是 0 4 2 4

结果是: 0 0 2 8

大家结合doReight，在看看，好像也是这么回事

那么又应该怎么修复呢？？

这里还不能再第一个IF加break

不然 2 2 2 0 就会变为 0 2 2 2了而不是 0 0 2 4

这是一个很纠结的问题

我们应该要循环遍历一下两个数字的中间是不是还有数字隔着，有就不加，没有就加

这里贴上所有逻辑代码

bool HelloWorld::doTop()
{
	for (int x = 0; x < 4; x++)
	{
		for (int y = 3; y >=0; y--)
		{
			for (int aftery = y-1; aftery >=0; aftery--)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][aftery]->getNumber());
					m_squarearray[x][aftery]->setNumber(0);
				}
				else if (m_squarearray[x][aftery]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					bool isAdd=false;
					for (int temp = aftery+1; temp < y; temp++)
					{
						if (m_squarearray[x][temp]->getNumber()!=0)
						{
							isAdd=true;
							break;
						}
					}
					if (isAdd)
					{
						continue;
					}
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[x][aftery]->setNumber(0);
					break;
				}
			}
		}
	}
	return true;
}
bool HelloWorld::doDown()
{
	for (int x = 0; x < 4; x++)
	{
		for (int y = 0; y <4; y++)
		{
			for (int aftery = y+1; aftery <4; aftery++)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[x][aftery]->getNumber());
					m_squarearray[x][aftery]->setNumber(0);
				}
				else if (m_squarearray[x][aftery]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					bool isAdd=false;
					for (int temp = y+1; temp < aftery; temp++)
					{
						if (m_squarearray[x][temp]->getNumber()!=0)
						{
							isAdd=true;
							break;
						}
					}
					if (isAdd)
					{
						continue;
					}
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[x][aftery]->setNumber(0);
					break;
				}
			}
		}
	}
	return true;
}
bool HelloWorld::doReight()
{
	for (int y = 0; y < 4; y++)
	{
		for (int x = 3; x >=0; x--)
		{
			for (int afterx = x-1; afterx >=0; afterx--)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[afterx][y]->getNumber());
					m_squarearray[afterx][y]->setNumber(0);
				}
				else if (m_squarearray[afterx][y]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					bool isAdd=false;
					for (int temp = afterx+1; temp < x; temp++)
					{
						if (m_squarearray[temp][y]->getNumber()!=0)
						{
							isAdd=true;
							break;
						}
					}
					if (isAdd)
					{
						continue;
					}
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[afterx][y]->setNumber(0);
					break;
				}
			}
		}
	}
	return true;
}
bool HelloWorld::doLeft()
{
	for (int y = 0; y < 4; y++)
	{
		for (int x = 0; x < 4; x++)
		{
			for (int afterx = x+1; afterx < 4; afterx++)
			{
				if (m_squarearray[x][y]->getNumber()==0)
				{
					m_squarearray[x][y]->setNumber(m_squarearray[afterx][y]->getNumber());
					m_squarearray[afterx][y]->setNumber(0);
				}
				else if (m_squarearray[afterx][y]->getNumber()==m_squarearray[x][y]->getNumber())
				{
					bool isAdd=false;
					for (int temp = x+1; temp < afterx; temp++)
					{
						if (m_squarearray[temp][y]->getNumber()!=0)
						{
							isAdd=true;
							break;
						}
					}
					if (isAdd)
					{
						continue;
					}
					m_squarearray[x][y]->setNumber(m_squarearray[x][y]->getNumber()*2);
					m_squarearray[afterx][y]->setNumber(0);
					break;
				}
			}
		}
	}
	return true;
}

5.为游戏增加动画效果

最后在来点，动画效果

这里，动画就是，在创建一个数字方块的时候他是慢慢放大的,

我们的数字方块是什么？？CCLayerColor

我也不知道为什么，我们之间这样

m_squarearray[x][y]->runAction(CCSequence::create(CCScaleTo::create(0,0,0),CCScaleTo::create(0.3f,1,1),NULL));

出现的效果并不理想。

那么我们就在SquareSprite中提供一个接口用来获得 m_layercolor

然后在用m_layercolor来执行动画

CCLayerColor* SquareSprite::getCClayerColor()
{
	return this->m_layercolor;
}

void HelloWorld::autoSquare()
{
	int x=CCRANDOM_0_1()*4;
	int y=CCRANDOM_0_1()*4;
	if (m_squarearray[x][y]->getNumber()>0)
	{
		autoSquare();
	}
	else
	{
		m_squarearray[x][y]->setNumber(2);
		m_squarearray[x][y]->getCClayerColor()->runAction(CCSequence::create(CCScaleTo::create(0,0,0),CCScaleTo::create(0.3f,1,1),NULL));
	}
}
