Keylistener

[dyelax]

Hey guys I'm trying to program a game of snake but my keylistener to change directions isn't working. I've set it up like all the examples I've seen online and I can't see what I'm missing. I've made a SSCCE for just the up direction (either 'w' or the up arrow key):

import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class GameSSCCE extends Applet implements KeyListener{
	private String direction;

	public void init(){
		setSize(300,100);
		direction = "No keys have been pressed.";
		addKeyListener(this);
	}
	
	public void paint(Graphics g){ g.drawString(direction, 60, 60); }
	
	public void keyPressed(KeyEvent e) {	
		if(e.getKeyChar() == KeyEvent.VK_W || e.getKeyChar() == KeyEvent.VK_UP){ 
			direction = "Up.";
		}
		repaint();
	}
	public void keyReleased(KeyEvent e) {}
	public void keyTyped(KeyEvent e) {}
}

KeyEvent.VK_W is a key code, not a key char.
Use the getKeyCode() method instead of getKeyChar()

Thanks! That was part of the problem. another part was that the applet did not have the keyboard focus originally so I had to click on it before typing. I put in setFocusable(true); and that fixed it.

I believe you can use the requestFocus(); method. Add it to the paint method.

But note that the recommended method to use is requestFocusInWindow().

Does your class extend Applet or JApplet?
