大家好，又见面了，我是你们的朋友全栈君。
这是本人第一篇博客，感谢收看，之后对游戏做出的修改，将以方法代码块放在最后
Form方法
100毫秒刷新
private void timer1_Tick(object sender, EventArgs e)
{
DrawSnake();
DrawFood();
}
秒刷新（蛇的移动速度由此决定）
private void timer2_Tick(object sender, EventArgs e)
{
Snake.SnakeMove(Snake.wasd);
EatFood();
TobeOrNotTobe();
label2.Text = score.ToString();
}
画蛇
public void DrawSnake()
{
RectangleF[] rectangles = new RectangleF[Snake.realsnake.Count];
int num;
for (num = 0; num < Snake.realsnake.Count; num++)
{
rectangles[num] = new RectangleF(Snake.realsnake[num].Location_x,
Snake.realsnake[num].Location_y, Snake.width, Snake.height);
}
this.Refresh();
Graphics g = this.CreateGraphics();
SolidBrush myBrush = new SolidBrush(Color.Black);
g.FillRectangles(myBrush, rectangles);
}
创建食物
public void newfood()
{
Food food = new Food();
foodx = food.Location_x;
foody = food.Location_y;
}
画食物
public void DrawFood()
{
Graphics f = this.CreateGraphics();
SolidBrush mybrush = new SolidBrush(Color.Red);
f.FillRectangle(mybrush, foodx, foody, 10, 10);
}
吃掉食物
public void EatFood()
{
if (Snake.realsnake[Snake.realsnake.Count - 1].Location_x == foodx
&& Snake.realsnake[Snake.realsnake.Count - 1].Location_y == foody)
{
newfood();
Snake.EatLong();
score += 1;
}
}
生存还是毁灭
public void TobeOrNotTobe()
{
int x = Snake.realsnake[Snake.realsnake.Count - 1].Location_x;
int y = Snake.realsnake[Snake.realsnake.Count - 1].Location_y;
if (!(x <= 500 && x >= 0 && y <= 500 && y >= 0))
{
GameOver();
timer2.Enabled = false;
}
}
游戏结束
public void GameOver()
{
label3.Visible = true;
label4.Visible = true;
label5.Text = score.ToString();
label5.Visible = true;
button1.Text = "重新开始";
button1.Visible = true;
}
button点击事件链
private void button1_Click(object sender, EventArgs e)
{
Snake.Snakestart();
newfood();
score = 0;
timer1.Enabled = true;
timer2.Enabled = true;
button1.Visible = false;
label3.Visible = false;
label4.Visible = false;
label5.Visible = false;
}
其他静态变量
static int score;
static int foodx, foody;
游戏主体类
点击开始游戏，开始游玩。

}
}
