C#Winform控件问题

Question

在form里定义两个控件，如picturebox1和picturebox2
我要让它们同时运动，每个有每个的运动方式（如picturebox1：x=sin t，y=t；picturebox2：x=t，y=480-t）
并用button1来控制picturebox1的停止运动，用button2来控制picturebox2的停止运动
请问大佬们该如何实现

Answer 1

首先这个控件不支持动态图像，除非你自己绘制坐标系和函数图像，重写它的onpaint方法或是用w p f

Answer 2

不是，这里的x、y为left与top

Answer 3

像flash一样动

Answer 4

在线程里面加控制标记，button控制标记来暂停或什么的，轨迹自行设置，这里随意设的using System;
using System.Collections.Generic;
using System.Drawing;
using System.Threading.Tasks;
using System.Windows.Forms;
 
namespace Demo_1
{
    public partial class Form1 : Form

        public class PanelEx : Panel
        {
            public PanelEx()
            {
                SetStyle(
                    ControlStyles.AllPaintingInWmPaint |
                    ControlStyles.OptimizedDoubleBuffer |
                    ControlStyles.ResizeRedraw |
                    ControlStyles.SupportsTransparentBackColor |
                    ControlStyles.UserPaint,
                    true
                    );
                UpdateStyles();
            }
        }

自己绘制坐标系和函数图像，重写它的onpaint方法或是用w p f

Answer 6

添加一个timer控件,在函数体里对button控件的.Location属性(x,y)同时增减x,y的值，x,y到最大或最小时改变一下，反向操作(最好创建两个全局int变量来控制增减多少，反向时乘以-1方向就可以改变方向)，创建两个全局bool变量IsMove1和IsMove2在改变button控件时用来判断是否增减值;同时如果是true就把变量变false,反之则异然。
