How can i set a Range values min/max according to another variable value ?

In one script i have the variable:

Code (csharp):

1.  
2. public int mapSize = 10;
3.  

Then i'm creating a grid of gameobjects and it will be always 10x10 if it was 11 then 11x11 or 9x9.

In another script:

Code (csharp):

1.  
2. using UnityEngine.UI;
3. using System;
4.  
5. public class WayPoints : MonoBehaviour
6. {
7.     public GameObject[] wayPoints;
8.  
9.     [Range(5, 50)]
10.     public int waypointsCount = 44;
11.  
12.     private System.Random random = new System.Random();
13.  
14.     // Use this for initialization
15.     void Start ()
16.     {
17.         var Nodes = UnityEngine.GameObject.FindGameObjectsWithTag("Node");
18.  
19.        
20.        
21.     }
22.    
23.     // Update is called once per frame
24.     void Update ()
25.     {
26.        
27.     }
28. }
29.  

I set the Range min to 5 ans max to 50
But i know that the map size is 10 so there will be 100 gameobjects.
So the range should be min 5 max 90 or maybe min 5 and max 50.

The problem is how can i make sure i will not set the Range max to be more then the map size ?
If the map size will be 5 so it's 25 gameobjects i can't set the Range max to 50.

 

Just set the highest part of the range to Mapsize * Mapsize.

Also, I think Unity's Random.Range is slightly easier to use.

 

But the variable mapSize is in another script. It's not in the WayPoints script.

 

Then do:

Code (CSharp):

1. public WayPoints WayPointScript;
2.  
3. //WayPointScript.mapSize;

Don't forget to drag the object with the WayPoints script into the Inspector slot that will show when you declare the public class.
