    text
    copied!<p>so I have a keyListener, I finally overcame the Keyboard input delay. I now have a new problem, <strong>When a user presses the "UP" arrow key to move "UP" they move "UP" for however long they want, then when the user presses the "DOWN" Arrow key, (<em>while</em> still holding the "UP" Arrow key) they move "DOWN".</strong> </p> <p><strong>How do I allow them to move "UP" again after the "DOWN" Arrow key has been released, without having to press the "UP" key again?</strong></p> <p><strong>(NOTE: The "UP" key is pressed throughout the whole process.)</strong></p> <p>here is the code I have currently use for listening for input. </p> <pre><code>private void keyListeners(){ GlobalObjects.frame.addKeyListener(new KeyListener() { @Override public void keyPressed(KeyEvent e) { //Up = 1 //Down = 2 //Left = 3 //Right = 4 if(e.getKeyCode() == 38){ System.out.println("UP KEY PRESSED"); player.setPlayerMovement(1); }else if(e.getKeyCode() == 40){ System.out.println("DOWN KEY PRESSED"); player.setPlayerMovement(2); }else if(e.getKeyCode() == 37){ player.setPlayerMovement(3); }else if(e.getKeyCode() == 39){ player.setPlayerMovement(4); } } @Override public void keyReleased(KeyEvent e) { if(e.getKeyCode() == 38){ if(player.getPlayerMovement() != 1){ System.out.println("UP KEY released, but some other arrow key changed the playermovement to a different number (do nothing)"); }else{ System.out.println("UP Key was a the last key pressed, therefore its safe to set player movement to "0" (not moving)"); player.setPlayerMovement(0); } }else if(e.getKeyCode() == 40){ if(player.getPlayerMovement() != 2){ }else{ player.setPlayerMovement(0); } }else if(e.getKeyCode() == 37){ if(player.getPlayerMovement() != 3){ }else{ player.setPlayerMovement(0); } }else if(e.getKeyCode() == 39){ if(player.getPlayerMovement() != 4){ }else{ player.setPlayerMovement(0); } } } @Override public void keyTyped(KeyEvent e) { } }); } </code></pre> <p>If you couldn't tell, this is a 2D RPG based game. (if that helps at all, answering the question)</p>
