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;
