I'm working on a 2d game in java. I have a problem using the key listener to move the character. I might be typing the code wrong or something but i need help fixing it. This is my player.java class:
import java.awt.event.*;
public class Player implements KeyListener{
public int x = 500, y = 300;
public int health = 100;
public int dx;
public int dy;
public Player(){
x = x + dx;
y = y + dy;
}
public int getXPos(){
return x;
}
public int getYPos(){
return y;
}
public int getHealth(){
return health;
}
public void keyPressed(KeyEvent e) {
int keyCode = e.getKeyCode();
if(keyCode == KeyEvent.VK_W){
dy = 2;
}
if(keyCode == KeyEvent.VK_A){
dx = -2;
}
if(keyCode == KeyEvent.VK_S){
dy = -2;
}
if(keyCode == KeyEvent.VK_D){
dx = 2;
}
}
public void keyReleased(KeyEvent e) {
int keyCode = e.getKeyCode();
if(keyCode == KeyEvent.VK_W){
dy = 0;
}
if(keyCode == KeyEvent.VK_A){
dx = 0;
}
if(keyCode == KeyEvent.VK_S){
dy = 0;
}
if(keyCode == KeyEvent.VK_D){
dx = 0;
}
}
}
In a different class i draw the character as a rectangle like this:
public void paint(Graphics g){
super.paint(g);
g.setColor(Color.BLACK);
g.fillRect(p.getXPos(), p.getYPos(), 25, 25);
}
The problem is the character doesn't move when i press the buttons. I'm relatively new to java. Any help will be greatly appreciated.
