我正在制作一个迷宫游戏，它使用 2D 数组来表示游戏板。目前，无论玩家当前位置在哪里，控制台都会输出“P”。但是，我想更改玩家“访问过”的数组中的每个元素并显示它以显示他们的路径。我该怎么做？我是否需要创建第二个重复数组以便对其进行更改？
这是我的代码:
import java.util.Scanner;
public class MazeGame {
private static char[][] maze = {
{'1','1','1','0','1','1','0','0','0','1','1','1','1'},
{'1','0','1','1','1','0','1','1','1','1','0','0','1'},
{'0','0','0','0','1','0','1','0','1','0','1','0','0'},
{'1','1','1','1','1','1','1','0','1','0','1','1','1'},
{'1','0','0','0','0','0','1','1','1','1','0','0','1'},
{'1','1','1','1','1','1','1','0','1','1','1','1','1'},
{'1','0','1','0','0','0','0','1','0','0','0','0','1'},
{'1','1','1','1','1','1','1','1','1','1','1','1','1'}
};
private static int playerRow = 0, playerCol = 0;
private static int moves = 0;
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
printMaze();
System.out.println("Welcome to the maze! Your goal is to make it from your starting position, the top left corner of the maze, to the end position, the bottom right corner of the maze. 1s represent spaces that you can move to, 0s represent walls that you can not move to, and Ps represent places that you have already been. To begin, enter an input: \n1-- 'U' for up\n2-- 'D' for down\n3-- 'L' for left\n4-- 'R' for right\n5-- 'Q' for quit\nHave fun playing the maze game and best of luck to you :)");
while (true) {
System.out.print("\nEnter a move (U/D/L/R/Q): ");
String move = input.nextLine();
if (move.charAt(0) == 'Q' || move.charAt(0) == 'q') {
System.out.println("Thanks for playing and have a wonderful day!");
System.exit(0);
}
if (move.length() == 1) {
if (move.charAt(0) == 'U' || move.charAt(0) == 'u') {
if (playerRow > 0 && maze[playerRow - 1][playerCol] != '0') {
playerRow--;
moves++;
} else {
System.out.println("Invalid move.");
}
} else if (move.charAt(0) == 'D' || move.charAt(0) == 'd') {
if (playerRow < maze.length - 1 && maze[playerRow + 1][playerCol] != '0') {
playerRow++;
moves++;
} else {
System.out.println("Invalid move. Please enter a valid move from the list below: \n1-- 'U' for up\n2-- 'D' for down\n3-- 'L' for left\n4-- 'R' for right\n5-- 'Q' for quit");
}
} else if (move.charAt(0) == 'L' || move.charAt(0) == 'l') {
if (playerCol > 0 && maze[playerRow][playerCol - 1] != '0') {
playerCol--;
moves++;
} else {
System.out.println("Invalid move.");
}
} else if (move.charAt(0) == 'R' || move.charAt(0) == 'r') {
if (playerCol < maze[0].length - 1 && maze[playerRow][playerCol + 1] != '0') {
playerCol++;
moves++;
} else {
System.out.println("Invalid move.");
}
} else {
System.out.println("Invalid move.");
}
} else {
System.out.println("Invalid move.");
}
printMaze();
if (playerRow == maze.length - 1 && playerCol == maze[0].length - 1) {
System.out.println("\nCongratulations, you have won the game in " + moves + " moves!");
break;
}
}
}
private static void printMaze() {
for (int i = 0; i < maze.length; i++) {
for (int j = 0; j < maze[0].length; j++) {
if (i == playerRow && j == playerCol) {
System.out.print("P ");
} else {
System.out.print(maze[i][j] + " ");
}
}
System.out.println();
}
}
}
最佳答案
就您而言，您可以在将玩家移动到其他部分之前立即在玩家所在的位置写入P。由于您的条件是 maze[playerRow][playerCol + 1] != '0' ，如果有 1 或 P 并不重要，它仍然是可访问的字段。
maze[playerRow][playerCol] = 'P'
playerCol++;
moves++;
