Hi Eno,

Sorry its taken so long for me to find this post.
there is a post about it here,
https://community.gamedev.tv/t/im-having-a-problem-with-random-range/153927/2

it looks like theres a Random class within
using UnityEngine
and
Using System

so its not quite sure which one to use.
hope that helps.
