Using vRP / ESX in C#

FiveM Resource Development & Modding Discussion

As the title says, is it possible to use vRP/ESX functions in C#? I know vRP is written in lua, so can I use them in C#?

You can get the ESX object like normal as it’s just an event with a callback. Use the dynamic type for the value of the callback value.

vRP won’t work.

I recall seeing someone reimplement the tunnel
stuff in C# or so though.

There’s a hacky fix by using an export made in lua that can then be called from your C#

exports("CallVRP", function(method_name, params)
  return vRP[method_name](params)
end)
6

for future references it is totally possibly to do GetSharedObject like esx does

first in vrp/base.lua under: vRP.user_sources = {} – user sources

Add:

AddEventHandler('vrp:getSharedVRP', function(cb)
	cb(vRP)
end)

function getSharedVRP()
	return vRP
end

now in vrp/client/base.lua under: Proxy.addInterface(“vRP”,tvRP)

Add:

AddEventHandler('vrp:getSharedVRP', function(cb)
	cb(tvRP)
end)

function getSharedVRP()
	return tvRP
end

then in c# (Example of Server sided plugin)

using System;
using CitizenFX.Core;
using static CitizenFX.Core.Native.API;

namespace Server
{
    public class Gta5Plugin_s : BaseScript
    {
        dynamic vRP;
        public Gta5Plugin_s()
        {
            TriggerEvent("vrp:getSharedVRP", new object[] { new Action<dynamic>(vrp => { vRP = vrp; })});
            EventHandlers["chatMessage"] += new Action<int, string, string>(OnChatMessage);
        }

        private void OnChatMessage(int src, string colour, string msg)
        {
            string[] args = msg.Split(' ');
            if (args[0].StartsWith("/"))
            {
                Player player = Players[src];
                CancelEvent();
                switch (args[0])
                {
                    case "/info":
                        var user_id = vRP.getUserId(src);
                        var BankDolla = vRP.getBankMoney(user_id); 
                        player.TriggerEvent("Gta5Plugin:Client:Info", BankDolla);
                        break;
                }
            }
        }
    }
}

Example of C# Client sided:

using System;
using CitizenFX.Core;
using CitizenFX.Core.UI;
using static CitizenFX.Core.Native.API;

namespace Client
{
    public class Gta5Plugin_c : BaseScript
    {
        public Gta5Plugin_c()
        {
            EventHandlers["Gta5Plugin:Client:Info"] += new Action<int>(Info);
        }
        private void Info(int Money)
        {
            Screen.ShowNotification($"~b~this is a test!!!~s~ {Game.Player.Name} : {Money}");
        }
    }
}
