title: 2D Spaceship movement math
body: <p>I'm trying to make a top-down spaceship game and I want the movement to somewhat realistic. 360 degrees with inertia, gravity, etc.</p>
  
  <p>My problem is I can make the ship move 360° with inertia with no problem, but what I need to do is impose a limit for how fast the engines can go while not limiting other forces pushing/pulling the ship.</p>
  
  <p>So, if the engines speed is a maximum of 500 and the ship is going 1000 from a gravity well, the ship is not going to go 1500 when it's engines are on, but if is pointing away from the angle is going then it could slow down.</p>
  
  <p>For what it's worth, I'm using <a href="http://www.scirra.com" rel="noreferrer">Construct</a>, and all I need is the math of it.</p>
  
  <p>Thanks for any help, I'm going bald from trying to figure this out.</p>
