自己动手实现一个《倒水解密》游戏
© Conmajia 2012
本文所有源代码和VisualStudio2010（.NET Fx 2.0）工程打包在本文最后下载。（别找我要源码，一概不理会）
《倒水解密》是一款很不错的手机益智类游戏，游戏界面如下：
规则是这样的：
有N个容量不同的瓶子，指定「将a升水倒入容量为b的瓶子」。游戏要求通过装水、倒水，达成给定的目标。
该游戏虽然简单，但可玩性高，也可有不同的难度变化，并且能锻炼玩家的心算能力。《倒水解密》不失为一个很好的繁忙工作之余的休闲方式。
说到这里，大家应该能猜到我想干什么了。没错，山寨之。
下面是山寨游戏的屏幕录像：
虽然界面有点简陋，但至少实现了。（屏幕录像软件不能录入鼠标光标，实际上鼠标光标是动态的）。
游戏操作方式如下：
- 在瓶子上双击右键可以把瓶子灌满水
- 双击左键可以把瓶子里的水倒掉
- 将一个瓶子拖动到另一个瓶子上可以把水倒过去
下面是游戏的模型结构。
Bottle类，表示瓶子。保存了瓶子的关键属性如容量、储量，以及基本方法如倒入、倒出。该类实现了IVisible可视化接口。这个接口很简单，只是提供了一个Draw()方法，用于重绘瓶子自身并返回图像。使用这种方式，可以方便的修改瓶子的外观样式而不用修改其他部分代码。例如可以简单的用矩形画瓶子，也可以像上面的手机游戏截图一样用非常的漂亮的贴图来做。
这里我用画图鼠绘了一个丑陋的瓶子作为例子。

Game类，游戏类。保存游戏世界，负责自动生成游戏和判定游戏胜利。

int maxAmount = 10;
for (int i = 0; i < bottleCount; i++)

world.CreateBottle(cap);
}

initiated = true;
}
bool capacityInside(int cap)

if (b.Capacity == cap)
return true;
}
return false;
}
public bool CheckSuccess()
{
if (targetBottle > -1)
{
if (initiated && world.Bottles.Count > targetBottle)
{
return world.Bottles[targetBottle].Content == targetAmount;
}
}
return false;
}
}
游戏的计时、计步、界面操作等统统放在主窗体，这里不做赘述。
简单的实现，还有倒计时、高分榜等功能可以扩展，界面也可以做的更漂亮些，欢迎大家扩展。
