the name 'scale' doesn't exist in the current context

Hi! I'm still new to this thing and I'm just watching tutorials. However, I can't seem to find solution to this one. can you please help me.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class TerrainGenerator : MonoBehaviour
4. {
5.  
6.     public int depth = 20;
7.     public int width = 256;
8.     public int height = 256;
9.  
10.     void start ()
11.     {
12.         Terrain terrain = GetComponent<Terrain>();
13.         terrain.terrainData = GenerateTerrain(terrain.terrainData);
14.     }
15.  
16.     TerrainData GenerateTerrain (TerrainData terrainData)
17.     {
18.         terrainData.size = new Vector3(width, depth, height);
19.         terrainData.SetHeights(0, 0, GenerateHeights());
20.         return terrainData;
21.     }
22.  
23.     float[,] GenerateHeights ()
24.     {
25.         float[,] heights = new float[width, height];
26.         for (int x = 0; x < width; x++)
27.         {
28.             for (int y = 0; y < height; y++)
29.             {
30.                 heights[x, y] = CalculateHeight(x, y);
31.             }
32.         }
33.  
34.         return heights;
35.     }
36.  
37.     float CalculateHeight (int x, int y)
38.     {
39.         float xCoord = x / width * scale;
40.         float yCoord = y / height * scale;
41.  
42.         return Mathf.PerlinNoise(xCoord, yCoord);
43.     }

 

There's no scale variable. You need to add one, either at the class level or inside the CalculateHeight method.

 

Please look at this page for how to post code properly (nicely!) on the forums: https://forum.unity3d.com/threads/using-code-tags-properly.143875/

 

Thank you for you reply! I'm sorry, I don't think I understand what you mean. Can you point me to a thread or a tutorial wherein I can learn that?

 

Okay.. the only thing I can think of, is to literally start at the beginning if that didn't make sense to you.
Here: https://unity3d.com/learn/tutorials/s/scripting

Start at the very first one..

because the answer is you write "float scale = 2f" or whatever value you want. and you do that inside the method, or at the class level (class level would be like how you have : depth, width, height; they are outside of methods**).
