Random role assigning from string array

Question

Simple enough : I have a system in place where I have a list of roles, cops /robbers, which is assigned in the inspector in the form of a string. How can I write a script which randomly assigns all agent a role, either cops or robbers , every time I start a new game?

Hello there,

This should give you what you need.

Put this script on any object in your scene, and in the inspector set:

• The number of Robbers

• The number of Cops

• A list of agents (you can name them if you like), with a count equal to the sum of the two numbers above.

Then run the game, and you'll get a list of Agents with a name and a random role.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class DistributeRolesClass : MonoBehaviour
 {
     // Serialized so you can view and edit it in the inspector
     [System.Serializable]
     public class Agent
     {
         public string agentName = "";
         private string agentRole = "";
 
         public string GetAgentRole()
         {
             return agentRole;
         }
 
         public void SetAgentRole(string newAgentRole)
         {
             agentRole = newAgentRole;
         }
     }
 
     public List<Agent> list_agents = new List<Agent>();
 
     // The sum of these 2 must be equal to the length of "list_agents"
     [Space]
     [Header("• Game Settings")]
     [SerializeField] private int i_numberOfRobbers = 0;
     [SerializeField] private int i_numberOfCops = 0;
 
     public void Start()
     {
         DistributeRoles();
     }
 
     private void DistributeRoles()
     {
         List<string> roles = new List<string>();
 
         for (int i = 0; i < i_numberOfRobbers; i++)
             roles.Add("Robber");
 
         for (int i = 0; i < i_numberOfCops; i++)
             roles.Add("Cop");
 
         foreach (Agent agent in list_agents)
         {
             string role = roles[Random.Range(0, roles.Count)];
             roles.Remove(role);
 
             agent.SetAgentRole(role);
         }
     }
 }

I hope that helps!

Cheers,
