Why I cant use Random.Range code system on Unity 2D

Question

I was using this code in unity 2D:

    float nilaiRandom;
    void Start()
    {
        nilaiRandom = Random.Range(1.11f, -1.88f);
        transform.position = new Vector2(transform.position.x, nilaiRandom);
    }

Unity count Error it says: Assets\\Go.cs(14,23): error CS0104: 'Random' is an ambiguous reference between 'UnityEngine.Random' and 'System.Random' What actually happened to my unity and what is the solution? please help me

Answer 1

.Net comes with System.Random and Unity comes with UnityEngine.Random . If you have both using System and using UnityEngine then there is ambiguity between them. Qualify the name to disambiguate:

UnityEngine.Random.Range(1.11f, -1.88f);
