Question

我正在为2D阵列项目制作迷宫游戏。到目前为止，我已经成功制作了一个随机游戏板。每次运行程序时，游戏板都是随机的。目标是让'P'（玩家）从右上角到'E'（结束）左下角，同时避免'X'和'*'。我需要帮助制作一种方法，允许玩家输入Up，Down，Right，Left并使P移动。这就是我到目前为止所做的：

public class MazeGame {
//Declare scanner to allow user to input directional commands
Scanner move = new Scanner(System.in);

public static void main(String[] args) {
    //Call methods
    Game_Beginning();
    Game_Board();     
}

//Intro to the game
public static void Game_Beginning(){
           System.out.println("This is your game board:");
    System.out.println("-------------------------------");
}

//Game Board
public static void Game_Board(){
    //Declare new array, maze 10x10
    char maze[][] = new char[10][10];

    //Randomly print the obstacles in the maze.
    for (int i = 0; i < maze.length; i++){
        for (int j = 0; j < maze.length; j++){
            double random = Math.random();
            if (random <= .05){
                maze[i][j] = '*';
            }
            else if (random > .06 && random <= .15){
                maze[i][j] = 'X';
            }
            else{
                maze[i][j] = '.';
            }
            maze[0][0] = 'P';
            maze[9][9] = 'E';
            System.out.print(maze[i][j]);
        }
        System.out.println("");
    }


}

/**
 *  Add a method called "makePMove." Define char right, char left and so on
 */
public static void makeMove(){
    int row;
    int col;
    System.out.print("Enter your move (Up-Down-Left-Right): ");

}

}

首先，您需要创建一个循环并识别用户命令。所以你可以在Game_Board（）方法之后添加这样的东西

while (true) {

        String playerInput = move.next();
        switch (playerInput) {
            case "u" :
                System.out.println("User command is 'up'");
                break;
            case "d" :
                System.out.println("User command is 'down'");
                break;
            case "l" :
                System.out.println("User command is 'left'");
                break;
            case "r" :
                System.out.println("User command is 'right'");
                break;
            case "e" :
                System.out.println("User command is 'exit'");
                break;
            case "y" :
                System.out.println("User command is 'yes'");
                break;
            case "n" :
                System.out.println("User command is 'no'");
                break;
            default:
                System.out.println("Unknown command '" + playerInput + "'!");
        }
    }

然后，一旦你知道你需要的方向是什么：
1.确定阵列/电路板中的目标位置 2.验证您的规则是否允许移动到目标位置
3.如果允许移动：
3.1。把P＆＃39; P＆＃39;进入目标位置 3.2。放＆＃39;。＆＃39;进入以前的位置＆＃39; P＆＃39;

还要确保已实现用户退出的预期行为。
