Walk and shoot not work in diagonal

Hy, i have a problem to manage imput game

i would implement all 8 movement + shoot in 8 direction, now i can move in 8 direction , shoot but stationary in 8 direction , and move and shoot in north,south,east,west,and north-east.

i have 5 volatile boolean (the problem not change without volatile)

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

that set true when arrow key is pressed with key binding and set false otherwise

    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() {

        private static final long serialVersionUID = 1L;

        @Override
        public void actionPerformed(ActionEvent e) {
            //directionMap.put(direction, true);
            north=true;
        }

    });
    actMap.put("UP" + "released", new AbstractAction() {

        private static final long serialVersionUID = 1L;

        @Override
        public void actionPerformed(ActionEvent e) {
            //directionMap.put(direction, false);
            north=false;
        }
    });


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

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

   @Override

   }
});

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

    west=false;
}
});

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

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

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

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

 //directionMap.put(direction, false);
    shoot=false;
}
});




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();
}

});

}

in the thread to control the booleans variable to realize also diagonal movement

            if(shoot){
            System.out.println("SHOOT");
            if(mondo.player.selectArm!=-1)
            mondo.proiettili.add(mondo.player.spara());
        }
        if(north && west && !south && !east){
            System.out.println("NORD OVEST");
            mondo.player.direction=(PuntiCardinali.NORTH_WEST);

        }
        if(north && east && !south && !west){
            System.out.println("NORD EST");
            mondo.player.direction=(PuntiCardinali.NORTH_EAST);


        }

        if(south && east && !north && !west){
            System.out.println("SUD EST");
            mondo.player.direction=(PuntiCardinali.SOUTH_EAST);

        }
        if(south && west && !north && !east){
            System.out.println("SUD OVEST");
            mondo.player.direction=(PuntiCardinali.SOUTH_WEST);

        }
        if(north && !west && !east && !south){
            System.out.println("NORD");
            mondo.player.direction=(PuntiCardinali.NORTH);

        }
        if(south && !west && !east && !north){
            System.out.println("SUD ");
            mondo.player.direction=(PuntiCardinali.SOUTH);

        }
        if(east && !north && !south && !west){
            System.out.println("EST");
            mondo.player.direction=(PuntiCardinali.EAST);

            }
        if(west && !north && !south && !east){
            System.out.println("OVEST");
            mondo.player.direction=(PuntiCardinali.WEST);
        }
        if(!north && !south && !east && !west)
            mondo.player.direction=(PuntiCardinali.STOP);

When i move only it work good, but when i shoot it work only for north,south,est,west and only north-east. why only north-east? if i stop direction with player oriented in any diagonal and shoot it shoot, It is as if when i move diagonal shoot became false
