How would I procedarally generate a terrain?
I don't even know where to start looking. I heard something about using Perlin noise, but how?
Perlin Noise is http://www.unifycommunity.com/wiki/index.php?title=Perlin_Noise
Although you can find road and terrain generators for unity, I couldn't find a free one yet. Except for http://www.unifycommunity.com/wiki/index.php?title=MazeGenerator that is not fully finished yet.
Ah, thanks for the Perlin noise link. But how exactly would I implement a random terrain generation feature using it?
there are a few paid scripts that use it to generate a random position for object prefabs, but it's a complex script, so you might consider buying if you depend on it for your application.
You don't need to buy packages to make a simple implementation of Perlin noise. Take a look at my question here: http://answers.unity3d.com/questions/298703/perlin-noise-continuous-through-different-objects.html. I've made a simple use of the Perlin function from the Unity Procedural Examples. I think it is a good starting point.
I would try using TerrainToolkit, available from the Resource -> Extensions part of the main unity site. Then you could use the API to create the terrain at runtime.
