java - Java语言的战舰游戏

问题描述

我需要一些关于我的学校项目代码的帮助。我用 Java 做了一些简单的游戏，它在 5x5 板上，随机定位的船只。

我被一些我无法独自管理的事情困住了，我需要更多的大脑来帮助我。我需要制作一艘需要将自己定位在船上 2 个位置的船，所以如果你正在与 PC 比赛，你需要两次射击才能击沉那艘船。

代码如下：

public static void main(String[] args) {
    int[][] board = new int[5][5];
    int[][] ships = new int[3][2];
    int[] shoot = new int[2];
    int attempts=0,
        shotHit=0;
    
    initBoard(board);
    initShips(ships);
    
    System.out.println();
    
    do{
        showBoard(board);
        shoot(shoot);
        attempts++;
        
        if(hit(shoot,ships)){
            hint(shoot,ships,attempts);
            shotHit++;
        }                
        else
            hint(shoot,ships,attempts);
        
        changeboard(shoot,ships,board);
        

    }while(shotHit!=3);
    
    System.out.println("\n\n\nBattleship Java game finished! You hit 3 ships in "+attempts+" attempts");
    showBoard(board);
}

public static void initBoard(int[][] board){
    for(int row=0 ; row < 5 ; row++ )
        for(int column=0 ; column < 5 ; column++ )
            board[row][column]=-1;
}

public static void showBoard(int[][] board){
    System.out.println("\t1 \t2 \t3 \t4 \t5");
    System.out.println();
    
    for(int row=0 ; row < 5 ; row++ ){
        System.out.print((row+1)+"");
        for(int column=0 ; column < 5 ; column++ ){
            if(board[row][column]==-1){
                System.out.print("\t"+"~");
            }else if(board[row][column]==0){
                System.out.print("\t"+"*");
            }else if(board[row][column]==1){
                System.out.print("\t"+"X");
            }
            
        }
        System.out.println();
    }

}

public static void initShips(int[][] ships){
    Random random = new Random();
    
    for(int ship=0 ; ship < 3 ; ship++){
        ships[ship][0]=random.nextInt(5);
        ships[ship][1]=random.nextInt(5);
        
        //let's check if that shot was already tried 
        //if it was, just finish the do...while when a new pair was randomly selected
        for(int last=0 ; last < ship ; last++){
            if( (ships[ship][0] == ships[last][0])&&(ships[ship][1] == ships[last][1]) )
                do{
                    ships[ship][0]=random.nextInt(5);
                    ships[ship][1]=random.nextInt(5);
                }while( (ships[ship][0] == ships[last][0])&&(ships[ship][1] == ships[last][1]) );
        }
        
    }
}

public static void shoot(int[] shoot){
    Scanner input = new Scanner(System.in);
    
    System.out.print("Row: ");
    shoot[0] = input.nextInt();
    shoot[0]--;
    
    System.out.print("Column: ");
    shoot[1] = input.nextInt();
    shoot[1]--;
    
}

public static boolean hit(int[] shoot, int[][] ships){
    
    for(int ship=0 ; ship<ships.length ; ship++){
        if( shoot[0]==ships[ship][0] && shoot[1]==ships[ship][1]){
            System.out.printf("You hit a ship located in (%d,%d)\n",shoot[0]+1,shoot[1]+1);
            return true;
        }
    }
    return false;
}

public static void hint(int[] shoot, int[][] ships, int attempt){
    int row=0,
        column=0;
    
    for(int line=0 ; line < ships.length ; line++){
        if(ships[line][0]==shoot[0])
            row++;
        if(ships[line][1]==shoot[1])
            column++;
    }
    
    System.out.printf("\nHint %d: \nRow %d -> %d ships\n" +
                             "Column %d -> %d ships\n",attempt,shoot[0]+1,row,shoot[1]+1,column);
}

public static void changeboard(int[] shoot, int[][] ships, int[][] board){
    if(hit(shoot,ships))
        board[shoot[0]][shoot[1]]=1;
    else
        board[shoot[0]][shoot[1]]=0;
}

跟随您的设计伙伴。

   public static void showShips(int[][] ships)
    {
        for (int ship = 0; ship < ships[0].length; ship++) {
            System.out.println("Ship: " + (ship + 1));
            System.out.println("Position 1: (" + (ships[ship][0]+1) + "," + (ships[ship][1]+1) + ")");
    }

    System.out.println("\t1 \t2 \t3 \t4 \t5");
    System.out.println();

    for (int row = 0; row < 5; row++) {
        System.out.print((row + 1) + "");
        for (int column = 0; column < 5; column++) {
            boolean flag = false;
            for (int ship = 0; ship < ships[0].length; ship++) {
                if (row == ships[ship][0] && column == ships[ship][1]) {
                    flag = true;
                }
            }
            if (flag) {
                System.out.print("\t" + "x");
            } else {
                System.out.print("\t" + "~");
            }
        }
        System.out.println();
    }
}
