Calling Game object from Element list?

I posted a question a little bit ago asking if there was something I was doing wrong. You were very helpful to direct me to another question. My goal with this is to select a random biome from my element list, and enable it [Well, sort of]. Is there something I am missing?

Preferably maybe changing the set active so I don't have like 20 biomes assets not active in my start at a time?

Here is the code.

using System.Collections; using System.Collections.Generic; using UnityEngine; public class SurfaceSelect : MonoBehaviour { public GameObject[] Biomes; public void Start() { SelectBiome(); } public void SelectBiome() { int i = Random.Range(0, Biomes.Length); Biomes[i].SetActive(true); } }
