Java games rock!


« Posted 2003-03-14 17:30:32 »

Hey guys!

I am using KeyListener.
I am making a game.
I have two problems:

1) In the method keyPressed, it has a little delay in the beginning when someone presses a key, that makes it unsuitable for runtime games.

2) I would like to be able to handle more than one key at a time.

What should I do ?

Hi!

Just create an array of 256 boolean values.

1  
boolean keys[] = new boolean[256];


Then, when a key is pressed, do something like that :

1  
2  
3  
4  
5  
6  
7  
8  
9  
public void keyPressed(KeyEvent e)
{
   keys[e.getKeyCode()] = true;
}

public void keyReleased(KeyEvent e)
{
   keys[e.getKeyCode()] = false;
}


Finally, in your draw method or anywhere you want, check keys' state :

1  
2  
3  
4  
5  
6  
7  
8  
9  
if(keys[KEY_EVENT.VK_UP])
{
   // Do something...
}

if(keys[KEY_EVENT.VK_DOWN])
{
   // Do something...
}


It should work...
