我正在尝试从KeyEvent 捕获上、下、右、左键，当我按下某个键时收到以下消息：

2021-06-05 00:46:11.176 java[47646:1823153] TSM AdjustCapsLockLEDForKeyTransitionHandling - _ISSetPhysicalKeyboardCapsLockLED 禁止

这是我的代码：

Character.java

import java.awt.Image;
import java.awt.event.KeyEvent;

import javax.swing.ImageIcon;


public class Character 
    private int dx;
    private int dy;
    private int x;
    private int y;
    private String imageLocation;
    private Image image;
    private boolean moveable;
    
    public Character(int x, int y, String imgLoc, boolean m)
        this.x = x;
        this.y = y;
        imageLocation = imgLoc;
        ImageIcon ii = new ImageIcon(this.getClass().getResource(imageLocation));
        image = ii.getImage();
        moveable = m;
    

    public void move() 
        if(moveable)
            x += dx;
            y += dy;
        
    

    public boolean moveable()
        return moveable;
    

    public int getX() 
        return x;
    

    public int getY() 
        return y;
    

    public Image getImage() 
        return image;
    

    public void keyPresed(KeyEvent e)
        int key = e.getKeyCode();

        if(key == KeyEvent.VK_LEFT)
            System.out.println("left key pressed");
            dx = -1;
        
        if(key == KeyEvent.VK_RIGHT)
            dx = 1;
        
        if(key == KeyEvent.VK_UP)
            dy = -1;
        
        if(key == KeyEvent.VK_DOWN)
            dy = 1;
        
    
    public void keyReleased(KeyEvent e) 
        int key = e.getKeyCode();

        if (key == KeyEvent.VK_LEFT) 
            dx = 0;
        

        if (key == KeyEvent.VK_RIGHT) 
            dx = 0;
        

        if (key == KeyEvent.VK_UP) 
            dy = 0;
        

        if (key == KeyEvent.VK_DOWN) 
            dy = 0;

我在 MacBook pro 2017 上使用 Visual Studio Code

请帮帮我！

【问题讨论】：

我没有看到任何与您提供的日志/输出一致的日志记录语句。

对不起！我没有上传其他课程。

【参考方案1】：

我认为问题在于最初按下 Caps-Lock 键，我在 here 上发现了一个类似的问题

我发现的另一个问题是 keyPressed 方法拼写错误为 keyPresed 也可能导致一些问题
