用C#创建Pong-从墙和球拍弹起球 [英] Creating Pong in C# - Bouncing the Ball off of Walls and Paddles Issue

问题描述

大家好，

作为有抱负的游戏开发人员，我决定使用C#语言在Visual Studio中重新创建经典的虚拟网球游戏Pong.

As an aspiring game developer, I have decided to recreate the classic virtual tennis game Pong in Visual Studio using the C# language.

问题是，除了VB.NET语言之外，我几乎没有编程经验，更不用说比基于文本的程序更复杂的东西了，所以我发现这项任务很难理解.

The problem with this is that I have very little programming experience outside of the VB.NET language, let alone anything more complicated than text-based programs so I'm finding this task understandably difficult.

话虽如此，我已经设法创建了一个使用鼠标控制的球拍，并为球创建了碰撞.那是我感到困惑的地方，因为当球与球拍接触时，我尝试过的所有动作似乎都不会产生反弹效果， 从而使游戏几乎无法玩.有人对我如何根据当前代码解决此问题有任何建议吗?

With that said, I have managed to create a paddle controlled using the mouse as well as created the collision for the ball. That's where I got confused, as nothing I have tried seems to create a bouncing effect when the ball comes in contact with the paddle, thus making the game virtually unplayable. Does anyone have any suggestions on to how I would tackle this issue based on my current code?

注意:我知道能够使用箭头键移动球似乎是不必要的，但这是我想到测试桨板碰撞的唯一方法.

NOTE: I know being able to move the ball using the arrow keys seems unnecessary but it's the only way I can think of testing the paddle collision.

        }

        void p_control(object sender, MouseEventArgs e)
        {
            pb_p_player.Top = e.Y ;
            this.Refresh();
        }

        void b_control(object sender, KeyEventArgs e)
        {
            int x = pb_ball.Location.X;
            int y = pb_ball.Location.Y;

            if (e.KeyCode == Keys.Right) x += 10;
            else if (e.KeyCode == Keys.Left) x -= 10;
            else if (e.KeyCode == Keys.Up) y -= 10;
            else if (e.KeyCode == Keys.Down) y += 10;

            pb_ball.Location = new Point(x, y);

            if (pb_ball.Bounds.IntersectsWith(pb_p_player.Bounds))
            {
                x += 10;
                pb_ball.Location = new Point(x, y);
            }

        }

        }
    }
}

刺客，

谢谢您在这里发布.

对于您的问题，请尝试以下代码.

For your question, please try the following code.

namespace ping_pong_game
{
    public partial class Form1 : Form
    {
        public int speed_left = 4;   //speed of ball
        public int speed_top = 4;
        public int point = 0;     //score point 

        public Form1()
        {
            InitializeComponent();
            timer1.Enabled = true;
            Cursor.Hide();   //hide the cursor
            this.FormBorderStyle = FormBorderStyle.None;  //remove any boder
            this.TopMost = true;   //bring the form to the front
            this.Bounds = Screen.PrimaryScreen.Bounds;   //make it fullscreen
            racket.Top = playground.Bottom - (playground.Bottom / 10);   //set the position of racket
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            racket.Left = Cursor.Position.X - (racket.Width / 2);   //set the center of  the racket  to the position of the cursor 
            ball.Left += speed_left;     //move the ball
            ball.Top += speed_top;

            if (ball.Bottom >= racket.Top && ball.Bottom <= racket.Bottom && ball.Left >= racket.Left && ball.Right <= racket.Right)    //racket collision
            {
                speed_top += 2;
                speed_left += 2;
                speed_top = -speed_top;// change the direction
                point += 1;
            }
            if (ball.Left<=playground.Left)
            {
                speed_left = -speed_left;
            }
            if (ball.Right>=playground.Right)
            {
                speed_left = -speed_left;
            }
            if (ball.Top<=playground.Top)
            {
                speed_top = -speed_top;
            }
            if (ball.Bottom>=playground.Bottom)
            {
                timer1.Enabled = false;   //ball is out ->stop  the game 
            }
        }

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Escape)
            {
                this.Close();      //press escape to quit
            }

        }
    }
}

我使用git来显示游戏.

I use a git to show the game.

操场和球是pictureBox.拍子就是面板.

playground and ball is pictureBox. racket is panel.

我希望这会有所帮助.

最好的问候，
