    copied!<p>I can not seem to get my player to move when certain keys are pressed. I did some debugging and placed a <code>System.out.print("Pressed);</code> in the if statements that check if a key is pressed and it prints out the message every time I press the key, they player just is not moving. Can someone help!</p> <p>here is the InputHandler class</p> <pre><code>public class InputHandler implements KeyListener { public InputHandler(Game game) { game.addKeyListener(this); } public class Key { private boolean pressed = false; public void toggle(boolean isPressed) { pressed = isPressed; } public boolean isPressed() { return pressed; } } // public List&lt;Key&gt; keys = new ArrayList&lt;Key&gt;(); public Key up = new Key(); public Key down = new Key(); public Key left = new Key(); public Key right = new Key(); public void keyPressed(KeyEvent e) { toggleKey(e.getKeyCode(), true); } public void keyReleased(KeyEvent e) { toggleKey(e.getKeyCode(), false); } public void keyTyped(KeyEvent e) { } public void toggleKey(int keyCode, boolean isPressed) { if (keyCode == KeyEvent.VK_W) { up.toggle(isPressed); } else if (keyCode == KeyEvent.VK_S) { down.toggle(isPressed); } else if (keyCode == KeyEvent.VK_A) { left.toggle(isPressed); } else if (keyCode == KeyEvent.VK_D) { right.toggle(isPressed); } } } </code></pre> <p>and here is the Player class</p> <pre><code>public class Player extends Mob { private InputHandler input; private int r = 10; public Player(int x, int y, int speed, InputHandler input) { super("Player", x, y, 1); this.input = input; this.x = x; this.y = y; } public boolean hasCollided(int dx, int dy) { return false; } public void update() { int dx = 0; int dy = 0; if (input.up.isPressed()) { dy--; } else if (input.down.isPressed()) { dy++; } else if (input.left.isPressed()) { dx--; } else if (input.right.isPressed()) { dx++; } if (dx != 0 || dy != 0) { move(dx, dy); isMoving = true; } else { isMoving = false; } if (x &lt; r) x = r; if (y &lt; r) y = r; if (x &gt; Game.WIDTH - r) x = Game.WIDTH - r; if (y &gt; Game.HEIGHT - r) y = Game.HEIGHT - r; } public void render(Graphics2D g) { g.setColor(Color.BLACK); g.fillOval(x - r, y - r, 2 * r, 2 * r); g.setStroke(new BasicStroke(3)); g.setColor(Color.GRAY); g.drawOval(x - r, y - r, 2 * r, 2 * r); g.setStroke(new BasicStroke(1)); } } </code></pre> <p>and here is the Mob class that has the <code>move()</code> method in it</p> <pre><code> public Mob(String name, int x, int y, int speed) { this.name = name; this.speed = speed; } public void move(int dx, int dy) { if (dx != 0 &amp;&amp; dy != 0) { move(dx, 0); move(dy, 0); numSteps--; return; } numSteps++; if (!hasCollided(dx, dy)) { if (dy &lt; 0) movingDir = 0; if (dy &gt; 0) movingDir = 1; if (dx &lt; 0) movingDir = 2; if (dx &gt; 0) movingDir = 3; x += dx * speed; y += dy * speed; } } public abstract boolean hasCollided(int dx, int dy); public String getName() { return _name; } } </code></pre>
