我对Java的东西是一个新手，但是..在网上阅读了很多内容之后，我一直在努力开发这款游戏并开始使用，我正在使用一些图片。我想通过KeyListener来更新他们的立场以展示运动的过程，我相信。不幸的是，图像仍然在同一个地方，拒绝移动D：

我确定我对这些代码进行了过度复杂的处理，但是这里是：\

public class Game extends javax.swing.JPanel implements ActionListener, KeyListener{

private Vladimir vlad;

private Timer timer;

public Game() {

addKeyListener(this);

setPreferredSize(new Dimension(1024,768));

setDoubleBuffered(true);

vlad = new Vladimir();

timer = new Timer(15,this);

timer.start();

}

public void actionPerformed (ActionEvent e){

repaint();

}

private void toggleKey(int keyCode, boolean pressed){

if (keyCode == 87){ // W

vlad.move("UP", pressed);

}

if (keyCode == 83){ // S

vlad.move("DOWN", pressed);

}

if (keyCode == 65) // A

{

vlad.move("LEFT", pressed);

}

if (keyCode == 68) // D

{

vlad.move("RIGHT", pressed);

}

}

public void keyPressed(KeyEvent e)

{

toggleKey(e.getKeyCode(), true);

}

public void keyReleased(KeyEvent e)

{

toggleKey(e.getKeyCode(), false);

}

public void keyTyped(KeyEvent e){

}

protected void paintComponent(Graphics g) {

super.paintComponent(g);

Graphics g2d = (Graphics2D)g;

g2d.drawImage(vlad.getGrassMap(),0,0,this);

g2d.drawImage(vlad.getCharOne(),vlad.getX(),vlad.getY(),this);

repaint();

}

}接着..

public class Vladimir{

private int x;

private int y;

private Image grassMapOne;

private Image charOne;

private String gMapLocate = "/phantasma/resources/GrassMap1.png";

private String charOneLocate = "/phantasma/resources/moveright1.png";

public Vladimir(){

ImageIcon gMap1 = new ImageIcon(this.getClass().getResource(gMapLocate));

ImageIcon char1 = new ImageIcon(this.getClass().getResource(charOneLocate));

grassMapOne = gMap1.getImage();

charOne = char1.getImage();

x = 512;

y = 350;

}

public void move(String direction, boolean keyHeld){

if (direction == "UP"){

y += 12;

}

if (direction == "DOWN"){

y -= 12;

}

if (direction == "LEFT"){

x -= 12;

}

if (direction == "RIGHT"){

x += 12;

}

}

public int getX(){

return x;

}

public int getY(){

return y;

}

public Image getGrassMap(){

return grassMapOne;

}

public Image getCharOne(){

return charOne;

}

}
