基于JAVA文本的迷宫游戏

Question

X表示起点，E表示出口。问题是我无法移动X。有人可以帮我弄这个吗。我们只允许使用main类和main方法，除此之外别无其他。每次用户输入时，迷宫地图都会显示，显示玩家的当前位置。当用户选择向左或向右时，当前位置不应更改。

Answer 1

一种便宜的解决方案是，在每次输入键盘后都以更新的位置打印迷宫

任务：

• 将M从主要方法移至常数-static String[][] M = ...;
• 键盘输入后绘制的设置循环-static boolean isDone
• 创建用于绘制迷宫的方法static void printMaze()
• 创建用于处理输入static void readInput()的方法
• 使用变量处理玩家位置-static int xPlayer和static int yPlayer

static String[][] M = ...
static boolean isDone;
static int xPlayer;
static int yPlayer;

public static void main(String []args){
    //repeated drawing of the screen after input
    while(!isDone){
        printMaze();
        readInput();    
    }
}

static void printMaze(){
    int height = M.length;
    for(int y = 0; y < height; y++){
        int width = M[0].length;
        for(int x = 0; x < width; x++){
            System.out.print(M[x][y]);
            if(x == xPlayer && y == yPlayer){
                System.out.print("X");
            }
        }
        System.out.println();
    }
    System.out.println();
}

static void readInput(){
    System.out.print("F - move Forward\tB - move Backward\t\nR - face Right\t\tL - face Left\n");
    System.out.print("Enter your move: ");
    String c = new Scanner(System.in).next();

    //handle input
    if (c.equalsIgnore("f")){
        yPlayer = yPlayer - 1;
    }
    //TODO: handle the other 3 directions the same way

    //BONUS: quit the loop 
    if (c.equalsIgnore("quit)){
        isDone = true;
    }
}
