Change terrain texture colour

Questions & Answers
1

I have two textures for my terrain. As a default I use the green texture. However I want my user to be able to change the settings of the game to make the texture red. I have buttons in place that change a string to either say “Green” or “Red”. At the start of my game, the below script is run.

using UnityEngine;
using System.Collections;

public class TerrainTexture : MonoBehaviour {

	public Texture green;
    public Texture red;

	public GameObject mapcheck;

	public Terrain terrain;

      void Update ()
      {
           if (mapcheck.GetComponent<Script>().map == "Green")
           {
            // Switch to Green
           }
           else if (mapcheck.GetComponent<Script>().map == "Red")
           {
            // Switch to Red
           }
       }
}

I have done a lot of research but I had various errors when I tried to put anything at my comments. What can I put in place to change the colour of the terrain? (Essentially switching the first texture to the second or vice versa).

In your case you should try to modify the terrain instead of the map, your texture on the TerrainLayer should be black and white and you should assign a Color and not a texture.
