Ich versuche ein Ping-Pong-Spiel zu machen, aber mein Ball bewegt sich nicht, also wie man den Ball bewegen lässt?Wie mache ich Code um den Ball zu bewegen?
Dies ist mein Code
package test;
import java.awt.*;
import java.awt.event.*;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.*;
public class pingpong1 extends JFrame implements Runnable {
public static void main(String[] args) {
pingpong1 ping = new pingpong1("PingPong Hard Game");
new Thread(ping).start();
ping.setSize(600, 300);
ping.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ping.setVisible(true);
} private int width, height;
private User user;
private Computer computer;
private Ball ball;
static int UserScore = 0;
int ComputerScore=0;
public pingpong1(String title){
}
@Override
public void paint(Graphics g){
super.paint(g);
Image img2;
ImageIcon img = new ImageIcon("pingpong.png");
img2 = img.getImage();
g.drawImage(img2,0,0, this);
ball.paint(g);
}
@Override
public void run(){
while(true){
ball.moveBall();
repaint();
try {
Thread.sleep(20);
} catch (InterruptedException e) {
Logger.getLogger(getName()).log(Level.SEVERE,null,e);
}
}
}
public void paintComponent(Graphics g) {
if (user == null) {
width = getWidth();
height = getHeight();
user = new User();
computer = new Computer();
ball = new Ball();
}
ball.draw(g);
}
public class User{
}
public class Computer{
}
public class Ball{
private int x,y;
private int centerX , centerY;
private Color color;
boolean go;
Ball(){
go=false;
}
public void paint(Graphics g) {
// TODO Auto-generated method stub
}
public Ball(int x,int y,Color color){
this.x=x;
this.y=y;
this.color=color;
this.centerX=5;
this.centerY=5;
}
public int getX(){
return x;
}
public int getY(){
return y;
}
public void moveBall(){
centerX=5;
x+=centerX;
y+=centerY;
} void draw(Graphics g){
Image img2;
ImageIcon img = new ImageIcon("pingpong.png");
img2 = img.getImage();
g.drawImage(img2, centerX - -35, centerY -10 , null);
}
}
}
warum _android_ Tag? –
Wann hast du damit gerechnet, dass der Ball an einem anderen Ort gezogen wird? Ich würde beim Zeichnen der Ballklasse raten. Wie auch immer, du rufst die Paint-Methode an (die nicht implementiert ist), wenn ich den Aufruf – Gildraths
