Creating a biome(ecosystem) script

Hey everyone, first post here

I am planning to create a open world horror survival game and it will have many awesome features including an infinite terrain with many different biomes.

So i'm quite new to scripting and was wondering what would be the best way of creating different biomes as the player moves in any direction,
* should I make some sort of grid?
* or use the distance the player moves in a direction before a new biome generates?
* or any other suggestions?
also if someone already has a script for something similar i'd love to study it and figure out how i'll make my own.
Everyone's feedback would be appreciated.

 

This is a big project for someone new to scripting.

You probably need to start smaller.

But a first step would be to look up Unity Marching Cubes, or minecraft tutorials and get a plain landscape working. Once you understand that you can think about modifying it to create biomes.

 

view please guys!
