我需要能够使用KeyListener和KeyBinding移动鸡的图像。我无法弄清楚如何让角色移动(鸡),我需要能够让他绕着框架移动。可以通过在我的代码中使用图像或将其转换为swing组件来完成。
这是我的代码:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.io.File;
import java.io.IOException;
import java.util.*;
import javax.imageio.ImageIO;
import javax.swing.*;
public class primary extends JFrame {
public primary(){
//Creates Title Image
JLabel title = new JLabel(" ");
ImageIcon tl = new ImageIcon("title.gif");
title.setIcon(tl);
//Creates Start Image
final JButton start = new JButton("");
ImageIcon st = new ImageIcon("start.gif");
start.setIcon(st);
//Creates Options Image
JButton options = new JButton("");
ImageIcon opt = new ImageIcon("options.gif");
options.setIcon(opt);
options.setBackground(Color.BLACK);
//Create first frame for "Start" button
final JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(1, 1));
p1.add(start, BorderLayout.CENTER);
//Create second panel for title label
final JPanel p2 = new JPanel(new BorderLayout());
p2.setLayout(new GridLayout(1, 3));
p2.add(title, BorderLayout.WEST);
//Create third panel for "Options" button
final JPanel p3 = new JPanel(new BorderLayout());
p3.setLayout(new GridLayout(1, 1));
p3.add(options, BorderLayout.SOUTH);
//Creates fourth panel to organize all other primary
final JPanel p4 = new JPanel(new BorderLayout());
p4.setLayout(new GridLayout(1, 3));
p4.add(p1, BorderLayout.WEST);
p4.add(p2, BorderLayout.CENTER);
p4.add(p3, BorderLayout.EAST);
//When button is clicked, it changes the level
start.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
if(start.isEnabled()) {
remove(p4);
setSize(1440, 500);
add(new ContentPanel1());
validate();
}
else {
return;
}
}
});
//Adds fourth panel to frame
add(p4, BorderLayout.CENTER);
}
public static void main(String arg[]) {
primary frame = new primary();
//Finds screen size of monitor
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
//Creates the frame
frame.setTitle("Cockadoodle Duty: Awakening");
frame.setSize(screenSize);
frame.setLocale(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
String background = "#000000";
frame.setBackground(Color.decode(background));
}
}
class coordinate {
public static int x;
public static int y;
}
class ContentPanel1 extends JPanel{
Image back = Toolkit.getDefaultToolkit().getImage("back.gif");
Image chick = Toolkit.getDefaultToolkit().getImage("chicken.gif");
Image corn = Toolkit.getDefaultToolkit().getImage("corn.gif");
ContentPanel1() {
MediaTracker mt = new MediaTracker(this);
mt.addImage(back, 0);
try {
mt.waitForAll();
} catch (InterruptedException e){
e.printStackTrace();
}
}
protected void paintComponent(Graphics g){
coordinate.x = 20;
coordinate.y = 321;
super.paintComponent(g);
int imwidth = back.getWidth(null);
int imheight = back.getHeight(null);
g.drawImage(back, 1, 1, null);
g.drawImage(chick, coordinate.x, coordinate.y, null);
g.drawImage(corn, 700, 337, null);
}
}
答案 0 :(得分:2)
private Point chickenLocation
字段。JComponent.WHEN_IN_FOCUSED_WINDOW
条件关联的那个。这样,JPanel就不需要专注于绑定工作。如果您仍然需要帮助,请向我们展示您的代码尝试以及您的具体问题。
