Wat is VDM (FiveM)? Definitie & preventie

Wat is VDM?

Vehicle Deathmatch (VDM) verwijst naar het gebruik van een voertuig als wapen om opzettelijk andere spelers te rammen, doden of verwonden zonder de juiste roleplay-rechtvaardiging. In FiveM roleplay-servers schendt VDM fundamentele serverregels en verstoort de roleplay-ervaring die spelers zoeken.

Waarom VDM belangrijk is

Roleplay-servers werken op het principe van realistische interactie. Wanneer een speler opzettelijk zijn voertuig in anderen ramt zonder roleplay-context, leidt dit tot:

Verbreekt de onderdompeling voor alle deelnemers
Voorkomt betekenisvolle verhaalontwikkeling
Creëert oneerlijke gameplay-voordelen
Leidt tot frustratie bij spelers en afname van het serveraantal

Veelvoorkomende VDM-scenario's

Duidelijke VDM-overtredingen:

Rijden op stoepranden om voetgangers te raken
Rammen van stilstaande voertuigen bij verkeerslichten
Voertuigen gebruiken om ziekenhuisingangen te blokkeren
Opzettelijk frontale botsingen veroorzaken

Grijze gebieden die context vereisen:

Politie pit-manoeuvres tijdens achtervolgingen
Bende-gerelateerde voertuigaanvallen met voorafgaande roleplay
Onbedoelde botsingen tijdens races
Reacties van hulpdiensten

Technische implementatie: Anti-VDM-systemen

Server-side detectiescript

-- resources/anti-vdm/server.lua
local vdmWarnings = {}
local VDM_THRESHOLD = 3
local DAMAGE_THRESHOLD = 50

RegisterServerEvent('vdm:checkCollision')
AddEventHandler('vdm:checkCollision', function(targetId, damage, speed)
 local source = source
 
 -- Validate input
 if not targetId or not damage or not speed then return end
 
 -- Check if damage and speed exceed thresholds
 if damage > DAMAGE_THRESHOLD and speed > 30 then
 local identifier = GetPlayerIdentifier(source, 0)
 
 -- Initialize warning count
 if not vdmWarnings[identifier] then
 vdmWarnings[identifier] = 0
 end
 
 vdmWarnings[identifier] = vdmWarnings[identifier] + 1
 
 -- Log incident
 local logData = {
 attacker = GetPlayerName(source),
 victim = GetPlayerName(targetId),
 damage = damage,
 speed = speed,
 timestamp = os.time()
 }
 
 TriggerEvent('vdm:logIncident', logData)
 
 -- Take action based on warnings
 if vdmWarnings[identifier] >= VDM_THRESHOLD then
 DropPlayer(source, 'Kicked for VDM violations')
 vdmWarnings[identifier] = 0
 else
 TriggerClientEvent('chat:addMessage', source, {
 args = {'^1[WARNING]', 'VDM detected. Warning ' .. 
 vdmWarnings[identifier] .. '/' .. VDM_THRESHOLD}
 })
 end
 end
end)

Client-side monitoring

-- resources/anti-vdm/client.lua
local lastCollision = 0
local COLLISION_COOLDOWN = 5000 -- 5 seconds

Citizen.CreateThread(function()
 while true do
 Citizen.Wait(0)
 local playerPed = PlayerPedId()
 
 if IsPedInAnyVehicle(playerPed, false) then
 local vehicle = GetVehiclePedIsIn(playerPed, false)
 
 if GetPedInVehicleSeat(vehicle, -1) == playerPed then
 if HasEntityCollidedWithAnything(vehicle) then
 local currentTime = GetGameTimer()
 
 if currentTime - lastCollision > COLLISION_COOLDOWN then
 local speed = GetEntitySpeed(vehicle) * 3.6 -- Convert to km/h
 
 -- Check for pedestrian collision
 local coords = GetEntityCoords(vehicle)
 local closestPed = GetClosestPed(coords.x, coords.y, coords.z, 
 5.0, 1, 0, 0, 0, -1)
 
 if DoesEntityExist(closestPed) and IsEntityAPed(closestPed) then
 local targetPlayer = NetworkGetPlayerIndexFromPed(closestPed)
 
 if targetPlayer ~= -1 then
 local damage = GetEntityHealth(closestPed)
 TriggerServerEvent('vdm:checkCollision', 
 GetPlayerServerId(targetPlayer), 
 damage, speed)
 end
 end
 
 lastCollision = currentTime
 end
 end
 end
 end
 end
end)

Serverconfiguratie

FiveM server.cfg toevoegingen:

# Anti-VDM Configuration
set vdm_enabled true
set vdm_max_warnings 3
set vdm_damage_threshold 50
set vdm_speed_threshold 30
set vdm_log_incidents true
set vdm_webhook "https://discord.com/api/webhooks/YOUR_WEBHOOK_HERE"

# Ensure anti-vdm resource starts
ensure anti-vdm

Beste Praktijken voor Serverbeheerders

1. Duidelijke Regeldefinitie

Maak specifieke VDM-regels in je serverdocumentatie:

Rule 2.1 - Vehicle Deathmatch (VDM)
- Using any vehicle as a weapon is prohibited
- Exceptions: Authorized police tactics, sanctioned events
- Punishment: 1st offense - Warning, 2nd - 24h ban, 3rd - Permanent ban

2. Staf Trainingsprotocol

Train moderators om VDM te herkennen:

Schade logboeken bekijken
Snelheid van speler bij impact controleren
Roleplay-context verifiëren
Bewijsmateriaal documenteren (clips, screenshots)

3. Speler Meldingssysteem

-- Simple reporting command
RegisterCommand('reportvdm', function(source, args, rawCommand)
 local targetId = tonumber(args[1])
 local reason = table.concat(args, ' ', 2)
 
 if not targetId or not reason then
 TriggerClientEvent('chat:addMessage', source, {
 args = {'^1[ERROR]', 'Usage: /reportvdm [player_id] [reason]'}
 })
 return
 end
 
 -- Create report ticket
 local report = {
 reporter = GetPlayerName(source),
 reported = GetPlayerName(targetId),
 reason = reason,
 timestamp = os.date('%Y-%m-%d %H:%M:%S'),
 status = 'pending'
 }
 
 -- Store in database or send to Discord
 TriggerEvent('vdm:createReport', report)
end, false)

Veelvoorkomende Implementatie-uitdagingen

Vals-positieven

Lag-geïnduceerde botsingsdetectie
Desync tussen spelers
Legitieme ongevallen

Oplossing: Implementeer respijtperiodes en contextcontrole:

-- Check if players are in active scenario
local function isInActiveRP(playerId)
 -- Check database for active scenarios
 -- Return true if player is in police chase, race, etc.
end

Prestatie-impact

Monitor script resourcegebruik:

-- Add to fxmanifest.lua
resource_monitor_mode 'yes'

Integratie met Populaire Frameworks

ESX Framework

ESX = nil
TriggerEvent('esx:getSharedObject', function(obj) ESX = obj end)

-- Add VDM violations to player record
RegisterServerEvent('vdm:recordViolation')
AddEventHandler('vdm:recordViolation', function(targetId)
 local xPlayer = ESX.GetPlayerFromId(source)
 MySQL.Async.execute('INSERT INTO vdm_violations SET identifier = @identifier, timestamp = @timestamp',
 {
 ['@identifier'] = xPlayer.identifier,
 ['@timestamp'] = os.time()
 })
end)

QBCore Framework

local QBCore = exports['qb-core']:GetCoreObject()

-- Integration with admin menu
QBCore.Commands.Add('checkvdm', 'Check player VDM history', {{name = 'id', help = 'Player ID'}}, true, function(source, args)
 local Player = QBCore.Functions.GetPlayer(tonumber(args[1]))
 if Player then
 -- Fetch VDM history
 MySQL.Async.fetchAll('SELECT * FROM vdm_logs WHERE citizenid = @citizenid', {
 ['@citizenid'] = Player.PlayerData.citizenid
 }, function(result)
 TriggerClientEvent('qb-admin:client:showVDMHistory', source, result)
 end)
 end
end, 'admin')

Testen van uw Anti-VDM Systeem

Geautomatiseerde testsuite

-- tests/vdm_test.lua
local function testVDMDetection()
 -- Simulate collision event
 local mockData = {
 attacker = 1,
 victim = 2,
 damage = 75,
 speed = 45
 }
 
 TriggerEvent('vdm:checkCollision', mockData.victim, mockData.damage, mockData.speed)
 
 -- Verify warning was issued
 -- Check if log was created
 -- Confirm webhook was triggered
end

Prestatiemetingen

Volg de systeemeffectiviteit:

-- Database schema
CREATE TABLE vdm_metrics (
 id INT AUTO_INCREMENT PRIMARY KEY,
 date DATE,
 total_incidents INT,
 warnings_issued INT,
 players_kicked INT,
 false_positives INT
);

Conclusie

VDM-preventie vereist technische implementatie, duidelijke regels en consistent handhaven om kwalitatieve roleplay-omgevingen in FiveM-servers te behouden.
