Random.Range alway return 0

I want my object to respawn at an position with a random y but the random alway return 0
here is my code
thank you and sorry about my bad english

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Random = UnityEngine.Random;
5.  
6. public class Respawn : MonoBehaviour
7. {
8.     private float speed = 4.5f;
9.     public float minY= -0.8f;
10.     public float maxY= 0.3f;
11.     void Start()
12.     {
13.     }
14.  
15.     // Update is called once per frame
16.     void Update()
17.     {
18.         transform.Translate(speed * -Time.deltaTime, 0, 0);
19.     }
20.     void OnTriggerEnter2D(Collider2D other)
21.     {
22.         float randomNumber = 0;
23.         randomNumber = Random.Range(minY, maxY);
24.         Debug.Log("Random Number is = " + randomNumber);
25.         if (other.transform.tag.Equals("Respawn"))
26.         {
27.             transform.position = new Vector3(5, randomNumber, 0);
28.         }
29.     }
30. }
31.  

 

Have you checked the values for Min and Max Y that have been serialised in the inspector? If you changed those values after you first created the script, they would have been serialised as 0.

 

Hmmm. have you tried to remove the "using Random = UnityEngine.Random" clause?

Also, note that your code will only Change the own object's Position to the new values if the other object has the "Respanwn" tag.

 

Check the minY and maxY in the Inspector, maybe it's defaulted to 0.

 

This code might help. I found it from a Unity Answers post years ago and modified it slightly.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public static class MyRandom
6. {
7.     static System.Random rnd = new System.Random();
8.  
9.     public static int Range(int min, int max)
10.     {
11.         return min + rnd.Next() % (max + 1);
12.     }
13.  
14.     public static float Range(float min, float max)
15.     {
16.         return min + rnd.Next() % (max + 1);
17.     }
18. }

 

@ADZ_: Avoid using System.Random, it's broken. Unity's random number generator is much better, so it's better to fix the issue.
