Java 迷宮游戲玩家移動不工作

Question

對於我的編碼項目，我必須編寫一個迷宮游戲。 但是，我目前在 JFrame 中顯示了一個迷宮，玩家用紅色方塊表示，結束標記是藍色方塊，牆壁是黑色方塊。 但是無論我嘗試做什么，我似乎都無法讓玩家在迷宮中移動。

package practiceMazeGame;

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class MazeBoard extends JFrame{

/**
 * 
 */
private static final long serialVersionUID = 1L;

// Creates the maze board using a 2D array.
public static int[][] maze =
    {{3,1,1,0,0,0,0,0,0,0,0,0,0,0,0},
    {0,0,0,0,1,1,1,1,1,1,0,1,1,1,1},
    {1,0,1,1,0,0,0,1,1,1,0,1,1,1,1},
    {1,0,1,1,0,1,0,1,0,1,0,0,0,0,0},
    {0,0,0,1,0,1,0,1,0,1,1,1,1,1,1},
    {0,1,1,0,0,1,0,1,0,1,0,0,0,0,1},
    {0,1,1,0,1,1,0,1,0,1,0,1,1,0,1},
    {0,0,0,0,1,1,0,1,0,1,0,1,0,0,1},
    {0,1,1,1,1,1,0,1,0,1,0,1,0,1,1},
    {0,0,0,1,1,1,0,1,0,1,0,1,0,0,0},
    {0,1,0,1,0,0,0,1,0,1,0,1,1,1,0},
    {0,1,1,1,0,1,1,1,0,1,0,0,0,1,0},
    {0,0,0,1,0,0,0,0,0,1,0,1,1,1,0},
    {0,1,1,1,1,1,1,1,0,1,0,1,1,1,0},
    {0,0,0,0,0,0,0,1,0,0,0,0,0,1,2},
    };

//Sets the output screen information
public MazeBoard() {
    // Displays 'Maze Game' in the title bar of the window.
    setTitle("Maze Game");
    // Sets the size of the output screen.
    setSize(640, 640);
    // Sets the location of where the window will appear.
    setLocationRelativeTo(null);
    // Stops the program when the window is closed.
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    PlayerMovement mySquare = new PlayerMovement(640, 640);   
    add(mySquare);

}

// The function in charge of the graphics of the maze.
public void paint(Graphics g) {
    super.paint(g);
    g.translate(50, 50);

    // They go through every section of the 2D array to make sure all the blocks are covered.
    for (int row =0; row <maze.length; row++) {
        for (int col = 0; col < maze[0].length; col++) {
            Color color;
            switch(maze[row][col]){
                // Sets the colour of the blocks of the array with a one to be black.
                case 1 : color = Color.black; break;
                // Sets the colour villain to be red.
                case 2 : color = Color.red; break;
                // Sets the colour of the player to be blue.
                case 3 : color = Color.blue; break;
                // Sets the colour of the rest of the maze to be white.
                default : color = Color.white; break;
            }

            // Sets the screen the for behind the maze.
            g.setColor(color);
            // Fills the rectangle needed for the maze with the colours previously decided.
            g.fillRect(30 * col, 30 * row, 30, 30);
            // Sets the colour of the gird lines for the maze.
            g.setColor(Color.black);
            // Draws the rectangle needed for the maze.
            g.drawRect(30 * col, 30 * row, 30, 30);
        }
    }
}

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            // Outputs the maze.
            MazeBoard view = new MazeBoard();
            view.setVisible(true);
        }
    });
}
}

我真的很感激一些幫助，謝謝。

給你的建議：

• 將玩家的位置存儲在您的數組中（作為 3 值）是糟糕的設計：您應該僅將其用於迷宮設計並將玩家的位置存儲在單獨的變量中

• 您的着色開關語句可以首先檢查繪制的位置是否與玩家的位置匹配，以確定藍色方塊應該在哪里。 或者你可以在你畫完迷宮后畫那個正方形

• 移動應該非常簡單：只需在檢查新位置沒有牆后更改玩家的位置變量
