（游戏：乒乓球）如何让我的球从我的移动物体反弹？ [英] (Game: ping pong) how do I make my ball bounce back from my moving object?

问题描述

您好，



我是游戏初学者，但我确实很挣扎。

我最近在编写一个基本的ping只有一个移动物体的乒乓球游戏，球从墙壁反弹，我想让我的球从我移动的矩形物体反弹。

你可以通过这个链接看到设计;

我完成了比分，计时和球运动等所有内容，但是在比赛期间我的球不会从我的矩形反弹回来。



如果您知道某些事情请告诉我。



代码中的信息;

球= picturebox1和红色矩形= picturebox2

Hello,

I am a beginner in making games but I do struggle with things.
I was lately programming a basic ping pong game with only one moving object, the ball bounces from the wall and I want to make my ball bounce from my moving rectangle object.
You can see the design with this link;
http://orig11.deviantart.net/d2ed/f/2016/095/8/a/test_by_benjaminhallows-d9xt9r4.png[^]

I did complete everything like the score, timing and ball movement but my ball doesn't bounce back from my rectangle when making contact during the game.

If you know something let me know.

For your information in the code;
The ball = picturebox1 and the red rectangle = picturebox2

namespace basicpingpong
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }
        int speed = 5;
        int cont = 0;
        int score = 0;

        bool Up;
        bool Left;

        private void timer1_Tick(object sender, EventArgs e)
        {
            if (pictureBox1.Left > pictureBox2.Left)
            {
               timer1.Enabled = false;
               MessageBox.Show("Score: " + score.ToString() + " points!");
               score = 0;
               speed = 5;
               cont = 0;

            }

            if(pictureBox1.Left+pictureBox1.Width >= pictureBox2.Left &&
                pictureBox1.Left+pictureBox1.Width <= pictureBox2.Left+pictureBox2.Width &&
                pictureBox1.Top+pictureBox1.Height >= pictureBox2.Top &&
                pictureBox1.Top+pictureBox1.Height <= pictureBox2.Top+pictureBox2.Height )
            {
                Left = true;
                score += 1;
                this.Text = "Score: " + score.ToString() + "";
                cont += 1;
                if(cont > 5)
                {
                    speed += 1;
                    cont = 0;
                }

            }


            #region Ball movement
            if(Left)
            {
                pictureBox1.Left += speed;

            }
            else
            {
                pictureBox1.Left -= speed;
            }

            if(Up)
            {
                pictureBox1.Top += speed;

            }
            else
            {
                pictureBox1.Top -= speed;
            }

            if (pictureBox1.Top >= this.Height -60)
            {
                Up = false;

            }
            if (pictureBox1.Top <= 0)
            {
                Up = true;
            }
 


            #endregion


        }

        private void Form2_FormClosing(object sender, FormClosingEventArgs e)
        {
            this.Owner.Show();
        }

        private void Form2_MouseMove(object sender, MouseEventArgs e)
        {
            pictureBox2.Top = e.Y;
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            this.Text = "Score: 0";
            Random random = new Random();
            pictureBox1.Location = new Point(0, random.Next(this.Height));
            Up = true;
            Left = true;
            timer1.Enabled = true;
            score = 0;

        }
    }
}
