一个泡泡的随机运动

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace 窗体移动{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();            //加载一个窗体事件            this.Load+=new EventHandler(Form1_Load);            //timer的Tick事件            t.Tick += new EventHandler(t_Tick);        }        //实例化一个Timer对象        Timer t=new Timer();        //定义两个变量        int b1=0,b2=0;         //timer的Tick事件        void t_Tick(object sender, EventArgs e)        {            //throw new NotImplementedException();                 this.Left += b2;            this.Top += b1;            //当窗体碰撞到窗体上边界或下边界控制上下的变量*-1            if (this.Top <= 0 || this.Bottom >= Screen.PrimaryScreen.WorkingArea.Height)            {                b1 *= -1;            }             //当窗体碰撞到窗体左边界或右边界控制上下的变量*-1            if (this.Left <= 0 || this.Right >= Screen.PrimaryScreen.WorkingArea.Width)            {                b2 *= -1;            }        }        //窗体加载事件        private void Form1_Load(object sender, EventArgs e)        {            //改变窗体透明度            this.Opacity = 0.7;            //将窗体解成一个椭圆            GraphicsPath g = new GraphicsPath();            g.AddEllipse(0,0,this.Width,this.Height);            this.Region = new Region(g);            //窗体的初始位置为（0,0）            this.Location = new Point(0, 0);            //生成两个随机数             Random a = new Random();            b1 = a.Next(2, 8);            b2 = a.Next(2, 8);            //启动timer并设置频率为10ms            t.Interval = 10;            t.Start();        }    }}

多个泡泡的随机运动

同一个泡泡运动原理相同，可多实例化几个窗口，这里作者提供一个方法

void showform(Form s，int b3,int b4)        {            s.Location = new Point(s.Location.X + b3, s.Location.Y + b4);            if (s.Location.Y <= 0 || s.Location.Y >= Screen.PrimaryScreen.WorkingArea.Height-s.Height)            {                b4 *= -1;            }            else if (s.Location.X <= 0 || s.Location.X >= Screen.PrimaryScreen.WorkingArea.Width-s.Width)            {                b3 *= -1;            }        }
