Question

Hy，我有一个管理输入游戏的问题

我将在8个方向上实现所有8个动作+射击，现在我可以在8个方向上移动，在8个方向上射击但是静止，并且在北，南，东，西和东北移动和射击。

我有5个易失性布尔值（问题没有变化而没有易失性）

DESC

当使用键绑定按下箭头键时设置为true，否则设置为

private volatile boolean north;
private volatile boolean east;
private volatile boolean south;
private volatile boolean west;
private volatile boolean shoot;

在线程中控制布尔变量以实现对角运动

    private void setKeyBindings() {

    InputMap inMap = getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
    ActionMap actMap = getActionMap();


         inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0, false), "UP" + "pressed");
         inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_UP, 0, true), "UP" + "released");

        actMap.put( "UP" + "pressed", new AbstractAction() {

inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0, false), "SPACE" + "pressed");
inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0, true), "SPACE" + "released");

inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_X, 0, false), "SUCCESSIVA" + "pressed");

actMap.put( "SUCCESSIVA" + "pressed", new AbstractAction() {

private static final long serialVersionUID = 1L;

@Override
public void actionPerformed(ActionEvent e) {
 //directionMap.put(direction, true);
    mondo.player.selectArmaSuccessiva();
}

});



inMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_Z, 0, false), "PRECEDENTE" + "pressed");

actMap.put( "PRECEDENTE" + "pressed", new AbstractAction() {

private static final long serialVersionUID = 1L;

@Override
public void actionPerformed(ActionEvent e) {
//directionMap.put(direction, true);
        mondo.player.selectArmaPrecedente();
}

});

}

当我移动时它只能运作良好，但是当我拍摄时它只适用于北，南，东，西和东北。为什么只有东北？如果我停止方向，任何对角线的球员和射击射击，好像当我移动对角线拍摄变得虚假时

步行和射击不对角线工作
