Random role assigning from string array

Questions & Answers
1

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,
