How to do it...

We will develop our terrain generator in just a single component:

1. Create a new class named TerrainGenerator:

using UnityEngine;public class TerrainGenerator : MonoBehaviour{  // next steps}

2. Define the member variables required for controlling size, height, and processing:

[Range(3, 101)]public int size;[Range(0.1f, 20f)]public float maxHeight;protected float[,] terrain;

3. Implement the initialization function:

public void Init(){  if (size % 2 == 0)    size++;  terrain = new float[size, size];  terrain[0, 0] = Random.value;  terrain[0, size-1] = Random.value;  terrain[size-1, 0] = Random.value;  terrain[size-1, size-1] = Random.value;}

4. Define the function for building the terrain. This is a huge function that implements the algorithm ...
