Part II: Assembling the Game Assets > Setting the Stage with Terrain

Chapter 5. Setting the Stage with Terrain

Now that you have a basic idea of what you want to make, you need to start compiling the various pieces and parts needed to bring the game to life. Some of these items, like terrain and simple primitive objects, can be created directly within Unity. Others, like a main character and special pick-up items, will need to be imported from other 3D modeling packages, such as Autodesk’s Maya or Blender. One of the flashier and more rewarding parts to start with is fleshing out the world’s environment—the physical space around which your character will run, jump, defeat enemies, and save the proverbial princess. Getting this laid out first will make placing your characters and items a bit easier and straightforward.

In Unity, game environments can be made, in effect, in three ways: using only terrain generated from within the engine, importing a complete 3D mesh of the world, or using a combination of terrain and meshes to carve out the world’s space. Widget will use the latter, but you may especially find it useful to make your entire game’s environment in a 3D package and just import it in at once—you’ll know that everything fits together and is exactly where you want it, without having to reposition. Unity’s free “3D Platformer” tutorial, available for download from their site, uses this method. If you find that you want something organic or want to simulate real-world landmasses, you should consider using terrain.
