Hi all,
sorry to ask but i can’t figure this one out.

error = Object reference not set to an instance of an object
world.createRandomWorld

script:

public GameObject cube;         //assign in the inspector
public GameObject[][][] cubes;
int sizex;
int sizey;
int sizez;

// Use this for initialization
void Start()
{
	sizex = 10;
            sizey = 10;
	sizez = 10;
	
	GameObject[,,] cubes = new GameObject[sizex,sizey,sizez];

    createRandomWorld();

}

void createRandomWorld()
{
	for (int countx = 0; countx < sizex; countx++)
	{
		for (int countz = 0; countz < sizez; countz++)
		{
			for (int county = 0; county < Random.Range(sizey - (sizey - 1), sizey); county++)
			{

//cubes[countx][county][countz] = cube; //doesn’t work
//cubes[countx][county][countz] = (GameObject) cube; //doesn’t work
cubes[countx][county][countz] = cube as GameObject; //doesn’t work
}
}
}
}

I think you should use public GameObject[,,] cubes; instead of public GameObject[][][] cubes;.
Second thing you have to change GameObject[,,] cubes = new GameObject[sizex,sizey,sizez]; to cubes = new GameObject[sizex,sizey,sizez];. Third change cubes[countx][county][countz] = cube; to cubes[countx,county,countz] = cube; .
