Ich erstelle ein Programm für ein Schulprojekt. Es ist ein auf Fans basierendes Programm von Pokémon und ich habe ein kleines Problem damit, wie ich Bilder basierend auf den Tastenanschlägen ändern kann.

Hier ist der Code für die Charakterklasse

import java.awt.Image;
import java.awt.event.KeyEvent;
import java.io.*;                        //the File class
import java.util.*;                     //the Scanner class
import javax.swing.ImageIcon;
import javax.swing.JPanel;
import java.awt.image.*;


import javax.swing.ImageIcon;

public class MainCharacter {

  private Image up, up1, up2, down, down1, down2, left, left1, left2, right, right1, right2;


  private void loadImages() {


     up = new ImageIcon("Up.png").getImage();
     up1 = new ImageIcon("Up1.png").getImage();
     up2 = new ImageIcon("Up2.png").getImage();
     down = new ImageIcon("Down.png").getImage();
     down1 = new ImageIcon("Down1.png").getImage();
     down2= new ImageIcon("Down2.png").getImage();
     left = new ImageIcon("Left.png").getImage();
     left1 = new ImageIcon("Left1.png").getImage();
     left2 = new ImageIcon("Left2.png").getImage();
     right = new ImageIcon("Right.png").getImage();
     right1 = new ImageIcon("Right1.png").getImage();
     right2 = new ImageIcon("Right2.png").getImage();

  }










/*public Image getImage() 
{
     //dont know what to return here
}
*/


  public void keyPressed(KeyEvent e) {

     int key = e.getKeyCode();

     if (key == KeyEvent.VK_LEFT) {

     //dont know what to do

     }

     if (key == KeyEvent.VK_RIGHT) {
        //dont know what to do

     }


     if (key == KeyEvent.VK_UP) {

        //dont know what to do
     }

     if (key == KeyEvent.VK_DOWN) {
        //dont know what to do
     }
  }

  public void keyReleased(KeyEvent e) {
     int key = e.getKeyCode();

     if (key == KeyEvent.VK_LEFT) {
        //dont know what to do
     }

     if (key == KeyEvent.VK_RIGHT) {
        //dont know what to do
     }

     if (key == KeyEvent.VK_UP) {
        //dont know what to do
     }

     if (key == KeyEvent.VK_DOWN) {
        //dont know what to do
     }
  }
}

Hier ist die Klasse, in der sie sich mit der Karte bewegt:

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

import javax.swing.JPanel;
import javax.swing.Timer;


public class MapMovement extends JPanel implements ActionListener {

private Timer timer;
private Map map;
 private MainCharacter mainCharacter;

public MapMovement() {

    addKeyListener(new TAdapter());
    setFocusable(true);
    setBackground(Color.BLACK);
    setDoubleBuffered(true);

    map = new Map();

    timer = new Timer(5, this);
    timer.start();
}


public void paint(Graphics g) {
    super.paint(g);

    Graphics2D g2d = (Graphics2D)g;
    g2d.drawImage(map.ge,tImage(), map.getX(), map.getY(), 1000, 1500, this);

    Toolkit.getDefaultToolkit().sync();
    g.dispose();
}


public void actionPerformed(ActionEvent e) {


      map.move();
    repaint();  
}


private class TAdapter extends KeyAdapter {

    public void keyReleased(KeyEvent e) {
        map.keyReleased(e);
            //mainCharacter.keyReleased(e);
    }

    public void keyPressed(KeyEvent e) {
        map.keyPressed(e);
            //mainCharacter.keyPressed(e);

    }
}

}

AKTUALISIEREN:

Hier ist die Map-Klasse

import java.awt.Image;
import java.awt.event.KeyEvent;

import javax.swing.ImageIcon;

public class Map {

private String map = "Map-1stCity.png";

private int dx;
private int dy;
private int x;
private int y;
private Image image;

public Map() {
    ImageIcon ii = new ImageIcon(this.getClass().getResource(map));
    image = ii.getImage();
    x = -100;
    y = -100;
}


public void move() {
    x += dx;
    y += dy;
}

public int getX() {
    return x;
}

public int getY() {
    return y;
}

public Image getImage() {
    return image;
}

public void keyPressed(KeyEvent e) {

    int key = e.getKeyCode();

    if (key == KeyEvent.VK_LEFT) {
        dx = 1;
    }

    if (key == KeyEvent.VK_RIGHT) {
        dx = -1;
    }

    if (key == KeyEvent.VK_UP) {
        dy = 1;
    }

    if (key == KeyEvent.VK_DOWN) {
        dy = -1;
    }
}

public void keyReleased(KeyEvent e) {
    int key = e.getKeyCode();

    if (key == KeyEvent.VK_LEFT) {
        dx = 0;
    }

    if (key == KeyEvent.VK_RIGHT) {
        dx = 0;
    }

    if (key == KeyEvent.VK_UP) {
        dy = 0;
    }

    if (key == KeyEvent.VK_DOWN) {
        dy = 0;
    }
}
}

Vielen Dank für all Ihre Hilfe im Voraus!
