copied!<p>Are you asking help on how to move smoothly? Like with acceleration? </p> <p>if so you can do something like this: </p> <p>Your player class should have a position,velocity and a direction vector. add your velocity to your position constantly, like this</p> <pre><code>//mainloop... { position.add(velocity); } </code></pre> <p>at rest you velocity is <0,0,0> so there is no position change, to move the playing simply add a percentage of your direction to you velocity like this.</p> <pre><code>if(Key.W) velocity.add(direction); </code></pre> <p>this is basicly acceleration. now to stop, you should add a percentage of your direction vector to your velocity, but in the opposite direction. </p> <pre><code>public class Camera { public final static Camera VIEW = new Camera();
