在winforms中移动pictureBox

Question

我的代码目标是在winforms中创建一个简单的pong游戏（应该使用monogame），但是我的代码应该可以工作。

问题：更改图片位置后，图片框位置不会更新。

我怀疑可能是我的一系列KeyDown / KeyUp事件占用了UI线程吗？

编辑：根据我最近进行的一些测试，似乎计时器没有计时，但是我可能错了。

代码：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        Thread t = new Thread(ChangePaddleState);
        t.Start();
        BringToFront();
        Activate();
    }

    //change this later?
    static bool upArrow = false;
    static bool downArrow = false;
    static bool wKey = false;
    static bool sKey = false;

    //movement speed of paddle
    const byte movementspeed = 3;

    Paddle paddleL = new Paddle();
    Paddle paddleR = new Paddle();

    void ChangePaddleState()
    {
        while (true)
        {
            //left paddle
            if (upArrow)
            {
                paddleL.idle = false;
                paddleL.movingDown = false;
                paddleL.movingUp = true;
            }
            else if (downArrow)
            {
                paddleL.idle = false;
                paddleL.movingUp = false;
                paddleL.movingDown = true;
            }
            //left paddle
            //right paddle
            if (wKey)
            {
                paddleR.movingDown = false;
                paddleR.idle = false;
                paddleR.movingUp = true;
            }
            else if (sKey)
            {
                paddleR.idle = false;
                paddleR.movingUp = false;
                paddleR.movingDown = true;
            }
            //checking if idle
            if(!paddleR.movingDown && !paddleR.movingUp)
            {
                paddleR.idle = true;
            }
            if (!paddleL.movingDown && !paddleL.movingUp)
            {
                paddleL.idle = true;
            }
