title: Camera for 2d game
body: <p>I'm currently making an awesome (in my mind) zombie game and I need to know a good way to make a camera. I am using the Slick2d library along with MarteEngine for java.</p>
  
  <p>I'm kinda new to java and jumped straight into a library before really getting deep into swing and such so this is probably a lack of graphics knowledge. I read on a tutorial that you can't actually move the window of the game on the map so instead you need to move the map and objects to make it seem like the camera is moving.</p>
  
  <p>If I was to do it this way it seems like it would be very resource intensive. I would have to loop through every zombie, survivor, object, hitbox, etc to move their coordinates. I've already tried this method once and things weren't really moving the same speed. That may have been due to me handling it with different update speeds.</p>
  
  <p>I've seen a few things on using graphics.translate but I don't really understand it. So.. any suggestions to making a camera move would be awesome! Thanks in advance.</p>
