在游戏中，子弹不会显示在网络客户端屏幕上

Question

大家好，所以我在坦克战争游戏中跑过网络并且是多人游戏，但每当我发射子弹时它会显示在我的屏幕上而不是其他玩家的屏幕上。你能帮忙吗，这里有一段代码形式，我认为问题来自：

class Tank implements Ball {

double locX, locY, radius, angle;
int self; // index of this tank in WarPanel.tanks
public boolean turnL, turnR, forth, back, fire;
boolean prevtL, prevtR, prevfo;
Color color;
Image image;

public static final double twoPi = Math.PI * 2.0;
public static final double turnRate = Math.PI / 8;
public static final double speed = 4.0;
public static final int RELOAD = 8; // delay between bullets
int count; // timer for reloading

public static final int MAXBULLETS = 7; // max simultaneous shots
Bullet bullets[] = new Bullet[MAXBULLETS];

AffineTransform saveAT; // place to hold current affine transform

public Tank(double x, double y, double a, int index, Image im){
    locX = x;
    locY = y;
    angle = a;
    self = index;
    image = im;
    radius = 22;
    // create bullets for this tank
    for (int i = 0; i < bullets.length; i++)
        bullets[i] = new Bullet(self);
}

public double getX() { return locX; }
public double getY() { return locY; }
public double getRadius() { return radius; }
public boolean isAlive() { return true; }

void update(Boolean local) {
    if (turnL)
        turnLeft(turnRate);
    if (turnR)
        turnRight(turnRate);
    if (forth){
        moveForward();
        // Check for rocks
        if (WarPanel.hitAnItem(this, WarPanel.rocks) >= 0)
            backUp();
    }
    if (local){
        if (turnL != prevtL){
          WarPanel.send("turnL "+turnL+" "+locX+" "+locY+" "+angle);
          prevtL = turnL;
        }
        if (turnR != prevtR){
          WarPanel.send("turnR "+turnR+" "+locX+" "+locY+"   "+angle);
          prevtR = turnR;
        }
        if (forth != prevfo){
          WarPanel.send("forth "+forth+" "+locX+" "+locY+" "+angle);
          prevfo = forth;
        }
    }
    if (fire){
        fireBullet();
    }
    // Update all of our bullets
    for (Bullet b: bullets)
        b.update();
}

public void processMove(String s){
    // Update movement parameters based on s
    Scanner sc = new Scanner(s);
    // Get the flag change
    String command = sc.next();
    boolean value = sc.nextBoolean();
    if (command.equals("turnL"))
        turnL = value;
    else if (command.equals("turnR"))
        turnR = value;
    else if (command.equals("forth"))
        forth = value;
    else
        System.out.println("Unexpected move: "+command);
    // then unpack position update
    locX = sc.nextDouble();
    locY = sc.nextDouble();
    angle = sc.nextDouble();
}

void paint(Graphics g){
    // Use the affine transform feature in Graphics2D
    // to easily rotate the tank's image.
    Graphics2D g2 = (Graphics2D)g;
    saveAT = g2.getTransform();
    g2.translate(locX, locY);
    g2.rotate(angle);
    g2.drawImage(image, (int)(-radius), (int)(-radius), null);
    // Reset the transform (this is important)
    g2.setTransform(saveAT);
    // Then draw bullets
    for (Bullet b: bullets)
        b.paint(g2);

}

void fireBullet(){
    // If it has been long enough since the last shot...
    count--;
    if (count > 0) return;
    // ...and if all the bullets aren't currently in use...
    int slot = getAvailableBullet();
    if (slot < 0)
        return;
    // ...then launch a new bullet
    bullets[slot].setLocation(locX, locY);
    bullets[slot].setDirection(angle);
    bullets[slot].reset();
    // Reset the timer
    count = RELOAD;
}

int getAvailableBullet(){
    for (int i = 0; i < bullets.length; i++)
        if (!bullets[i].isAlive())
            return i;
    return -1;
}

void turnRight(double a){
    angle += a;
    if (angle > twoPi)
        angle -= twoPi;
}

void turnLeft(double a){
    angle -= a;
    if (angle < 0.0)
        angle += twoPi;
}

void moveForward(){
    locX += speed*Math.cos(angle);
    locY += speed*Math.sin(angle);
}

void backUp(){
    locX -= speed*Math.cos(angle);
    locY -= speed*Math.sin(angle);
}
}
