Java在按键后是否立即继续移动？

当我按下任何键箭头时，红色框移动，是的，移动10px，然后停止1秒&继续移动，而不是不停地立即移动

发生问题的示例：

（来源：）

你能看到它是如何停止1秒或0.5秒并继续的吗

我怎样才能修好它

我正在使用

KeyEventDispatcher

我的钥匙检测：

整个src：

public class Game extends Frame {

    private class Keyboard implements KeyEventDispatcher {

        private Game game;

        public Keyboard(Game game) {
            this.game = game;
        }

        @Override
        public boolean dispatchKeyEvent(KeyEvent e) {
            if (e.getID() == KeyEvent.KEY_PRESSED) {
                this.movement(e);
            } else if (e.getID() == KeyEvent.KEY_RELEASED) {
            } else if (e.getID() == KeyEvent.KEY_TYPED) {
            }
            return false;
        }

        public void movement(KeyEvent e) {
            int keyCode = e.getKeyCode();
            switch( keyCode ) { 
                case KeyEvent.VK_UP:
                    game.movePlayer(0, -10);
                    break;
                case KeyEvent.VK_DOWN:
                    game.movePlayer(0, 10);
                    break;
                case KeyEvent.VK_LEFT:
                    game.movePlayer(-10, 0);
                    break;
                case KeyEvent.VK_RIGHT :
                    game.movePlayer(10, 0);
                    break;
             }

问题在于击键的重复率。这是由操作系统控制的

解决方案是在按下该键后立即使用摆动计时器来安排动画

另外，您不应该使用KeyListener，但intead应该使用KeyBinding。

我认为问题不在您提供的代码范围之内。构建SSCCE将为您解决问题，或者为其他人提供他们需要的信息。@jzd信息，比如什么？我真的不知道是什么代码导致了这个问题，但我很确定这是我为自己的需要所做的错误的关键事件。没有SSCCE，很难诊断问题。更新延迟指向的不是KeyEvent处理。
