How to Build a Multi-Identifier Ban System for FiveM

Building a robust multi-identifier ban system for your FiveM server is crucial for maintaining a fair gaming environment. As server owners know, players can often evade bans by creating new accounts or using different identifiers (IDs). In this guide, we will delve into practical steps and configurations to create an effective multi-identifier ban system that works seamlessly across player sessions.

Understanding the Need for a Multi-Identifier Ban System

Before we dive into implementation, let’s explore why a multi-identifier ban system is necessary:

• Accountability: Players can dodge bans with new identifiers, leading to repeated offenses.
• Security: Protects server integrity by ensuring that problematic players can't easily return.
• Fairness: Maintaining a level playing field for all players.

With the rise of roleplay servers using frameworks like ESX or QBCore, implementing a multi-identifier ban system becomes even more crucial in managing player behavior effectively.

Step 1: Setting Up Your Database

You'll need to track banned identifiers within your server’s database. If you're using a MySQL database, you can follow these steps:

Create a Ban Table

Run the following SQL command to create a new table that will hold your ban records:

CREATE TABLE IF NOT EXISTS bans (
    id INT AUTO_INCREMENT PRIMARY KEY,
    identifier VARCHAR(255) NOT NULL,
    reason TEXT NOT NULL,
    admin VARCHAR(255) NOT NULL,
    timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Ensure to structure your bans table to include multiple identifiers per player.

Step 2: Modifying Your Server Configuration

Next, we will modify necessary configuration files to utilize this ban system effectively.

Update server.cfg

In your server.cfg, ensure you have the following line to set yourself up for database usage:

set mysql_connection_string "server=localhost;database=fivem;userid=root;password=yourpassword"

Replace the placeholder values with your actual database credentials.

Create a Resource for Ban Management

Create a new resource folder named ban_system in your resources directory and add fxmanifest.lua:

fx_version 'cerulean'
game 'gta5'

author 'Your Name'
description 'Multi-Identifier Ban System'
version '1.0'

server_script 'server/main.lua'

Step 3: Scripting the Ban Functionality

You’ll need to code the functionality behind your ban system. In the server folder, create a file called main.lua and include the following logic:

Example Code Snippet for Banning Players

RegisterCommand('ban', function(source, args, rawCommand)
    local identifier = GetPlayerIdentifiers(source)[1] -- Get the player’s identifier
    local reason = table.concat(args, " ") 
    local admin = GetPlayerName(source)  

    exports.ghmattimysql:execute("INSERT INTO bans (identifier, reason, admin) VALUES (?, ?, ?)", {identifier, reason, admin})
    DropPlayer(source, 'You have been banned: ' .. reason)
end, false)

This command allows admins to ban players, logging the identifier along with the reason and admin name.

Step 4: Checking Ban Status

To prevent banned players from connecting, you must check if their identifier exists in the bans table. Modify your main.lua with:

AddEventHandler('playerConnecting', function(name, setKickReason, deferrals)
    local identifiers = GetPlayerIdentifiers(source)
    for _, id in ipairs(identifiers) do
        local result = exports.ghmattimysql:executeSync("SELECT * FROM bans WHERE identifier = ?", {id})
        if result[1] then
            setKickReason('You are banned: ' .. result[1].reason)
            deferrals.done()
            return
        end
    end
    deferrals.done()
end)

This code ensures that when a player attempts to connect, their identifiers are checked against the bans in the database.

Step 5: Testing and Troubleshooting

After implementing your multi-Identifier ban system, it’s essential to test its functionality. Here are the steps to follow:

1. Test the Ban Command: Use in-game commands to ban a player and verify their identifier appears in the database.
2. Check Kick Messages: Ensure that banned players receive the proper kick message upon attempting to connect.
3. Test Multiple Identifiers: Ban a player from multiple identifiers, and check the functionality across those bans.

Common Issues to Look For

• Database Connection Errors: Ensure your connection string is correct and your database server is running.
• Script Errors: Check the server console for any Lua syntax errors.
• Permission Issues: Ensure that the ban command is limited to admins. You might want to implement a permission check.

Additional Features to Consider

Once your basic multi-identifier ban system is operational, consider implementing additional features for enhanced management:

• Unban Command: Allow admins to unban users via a command.
• Ban Duration: Implement temporary bans for a set period.
• Logging: Keep detailed logs of all bans and unbans for accountability.

Frequently Asked Questions

Q1: Can I integrate this ban system with ESX or QBCore?
A1: Yes, you can adapt the scripts to utilize the database connection methods provided by both frameworks.

Q2: How can I prevent false bans?
A2: Implement an appeal system where players can contest their bans, allowing admins to review the case.

Q3: What if a banned player changes their identifier?
A3: The multi-Identifier system is designed to ban all identifiers linked to a player, so make sure to log all known identifiers.

Q4: Is there a way to automate ban management?
A4: Yes, you can set up scheduled scripts that check for multiple bans on similar identifiers and flag suspicious activity.
