유니 (uni)를위한 임무가 주어졌으며 사용자가 방향키를 사용하여 게임을 제어 할 수 있도록해야합니다.자바 키 바인딩
지금까지 다음과 같은 사항이 있지만 작동하지 않습니다. 제가 빠진 것이 명백합니까?
// key bindings
// add the key bindings for up, down, left and right to the input map
gamePanel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_DOWN,0), "down");
gamePanel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_UP,0), "up");
gamePanel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_LEFT,0), "left");
gamePanel.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_RIGHT,0), "right");
// assign actions to the key bindings in the action map
gamePanel.getActionMap().put("down", new AbstractAction()
{
public void actionPerformed(ActionEvent event)
{
move("DOWN");
}
});
gamePanel.getActionMap().put("up", new AbstractAction()
{
public void actionPerformed(ActionEvent event)
{
move("UP");
}
});
gamePanel.getActionMap().put("left", new AbstractAction()
{
public void actionPerformed(ActionEvent event)
{
move("LEFT");
}
});
gamePanel.getActionMap().put("right", new AbstractAction()
{
public void actionPerformed(ActionEvent event)
{
move("RIGHT");
}
});
