Random.Range doesn't work

Question

using UnityEngine; using System.Collections; using System.Collections.Generic;

public class ChallengeController : MonoBehaviour {

 public float scrollSpeed = 5.0f; //brzina micanja
 public GameObject[] challenges;
 public float frequency = 0.5f;
 float counter = 0.0f;
 public Transform challengesSpawnPoint;

 // Use this for initialization
 void Start () {
     GenerateRandomChallenge();
 }
 
 // Update is called once per frame
 void Update () {
     //generiranje objekata
     if(counter <= 0.0f)
     {
         GenerateRandomChallenge();
     }
     else
     {
         counter -= Time.deltaTime * frequency;
     }
     //Scrolling
     GameObject currentChild;
     for (int i = 0; i < transform.childCount; i++)
     {
         currentChild = transform.GetChild(i).gameObject;
         ScrollChallenge(currentChild);
         if (currentChild.transform.position.x <= -15.0f) //da unistimo sto je sve previuse iza nas
         {
             Destroy(currentChild);
         }
     }
 }


 void ScrollChallenge (GameObject currentChallenge) 
 {
     currentChallenge.transform.position -= Vector3.right * (scrollSpeed * Time.deltaTime); //pomicanje ekrana u desno
 }

 void GenerateRandomChallenge()
 {
     Instantiate(challenges[(Random.Range(0 , challenges.Length)], challengesSpawnPoint.position, Quaternion.identity); //here it says that the nested type 'Range' does not exist in the type 'UnityEngine.Random'
     counter = 1.0f;
 }

}

It looks like you aren't using the "Random" library. See at the top where it says:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;

you need to add:

 using Random = UnityEngine.Random;

That will make it so that when you use the "Random.Range" it knows where the code you are trying to get to is.

p.s, you can find a lot of information about random stuff in this unity tutorial on making a rougelike.

I hope that helps, and good luck with your game.

In my case Range = Random.Range(minRange, maxRange);

There is values in min max range .... For example 4 and 8 When I start playing the range is fixed ..... It is not updating to different random Range after ..... Actually I want to make like .... It takes random range Evey time I think it is hard to explain but pls tell if you understand
