新手学习c# 在博客园上看到后自己模仿打出来的第一个程序 开心，纪念一下
bean ：食物类
block ：蛇块类
snake ：蛇类
Map ：地图 图形类
食物类：
class bean
{
private Point _origin;//用于画食物顶端坐标 public Point Origin//封装字段
{
get { return _origin; }
set { _origin = value; }
}
//显示食物方法
public void showBean(Graphics g)
{
//定义红色画笔
SolidBrush brush = new SolidBrush(Color.Red);
//用实心矩形画食物
g.FillRectangle(brush, _origin.X, _origin.Y, , );
}
//食物消失方法
public void unShowBean(Graphics g)
{
//定义背景色画笔
SolidBrush brush = new SolidBrush(Color.Red);
//用实心矩形画食物
g.FillRectangle(brush, _origin.X, _origin.Y, , );
}
}
蛇块类：2020-02-16
public class block
{
//是否是蛇头
private bool _isHead; public bool IShead
{
get { return _isHead; }
set { _isHead = value; }
}
//蛇块编号
private int _blockNumber; public int BlockNumber
{
get { return _blockNumber; }
set { _blockNumber = value; }
}
//蛇块在左上角的位置
private Point _origin; public Point Origin
{
get { return _origin; }
set { _origin = value; }
} //根据指定位置画蛇块
public void showBlock(Graphics g)
{
Bitmap bitMap;
if (IShead)
{
bitMap = new Bitmap(Image.FromFile("blue.gif"));
}
else
{
bitMap = new Bitmap(Image.FromFile("Yellow.gif"));
}
g.DrawImage(bitMap, Origin.X, Origin.Y, , );
}
//蛇块消除
public void UnShowBlock(Graphics g)
{
SolidBrush brush = new SolidBrush(Color.Silver);
g.FillRectangle(brush,Origin.X,Origin.Y,,);
}
}
蛇类：
public class Snake

//游戏开始时初始的蛇

}

}
//蛇边长函数
public void snakeGrowth()

}
//蛇先前运动 没有吃到食物
public void Go(Graphics g)
{
block snakeTail = blockList[];
//消除蛇块

//集合中移除尾巴
blockList.RemoveAt();
//序号全部减1
foreach (var item in blockList)

}
//蛇的方向转换
public void turnDriction(int pDriction)

}
}
不是自己想的 但是我弄懂了
