title: Terrain and Collision in a Game
body: <p>I am attempting to create a new Game in which a vehicle drives along the ground, but also has the capability to use thrusters to become temporarily airborne. </p>
  
  <p>I am relatively new to game programming, but I am rather good at coding in Java, C, C++ etc., so I do not think that should be an issue (thought the first iteration of the game is in Java). My problem is that I am starting from scratch, and can not think of a way for the terrain to be a barrier so the vehicles do not fall right through it. And how can I have them possibly take fall damage?</p>
  
  <p>In the past people have directed me to the Replica Island source since it has this already in it, and I see the whole Collision System, but so far I have not been able to make sense of it and I was hoping somebody would be willing to lend me a hand. </p>
  
  <p>Thank you</p>
