QB-PoliceJob - Police Department System

The qb-policejob resource provides a comprehensive police department system for QBCore servers, featuring MDT integration, evidence management, vehicle impounding, arrest mechanics, and complete law enforcement operations.

Overview

QB-PoliceJob creates a realistic police experience with advanced systems for investigations, arrests, evidence collection, and department management. Officers can access mobile data terminals, manage evidence, process arrests, and coordinate law enforcement activities.

Key Features

  • Mobile Data Terminal (MDT): Complete police database and dispatch system
  • Evidence System: Crime scene investigation and evidence management
  • Vehicle Impound: Vehicle seizure and storage system
  • Arrest Mechanics: Handcuffs, booking, and jail processing
  • Police Vehicles: Emergency vehicles with equipment
  • Weapon Management: Police armory and weapon access
  • Radar System: Speed detection and traffic enforcement
  • Department Ranks: Hierarchical police structure
  • Emergency Alerts: Automatic dispatch system

Installation

Prerequisites

  • QBCore Framework
  • qb-target (for interaction system)
  • qb-menu (for police menus)
  • qb-input (for police forms)
  • qb-inventory (for police equipment)
  • qb-garage (for police vehicles)

Installation Steps

  1. Download the Resource
cd resources/[qb]

Troubleshooting

Common Issues

Handcuffs Not Working

-- Check if player has handcuff item
local handcuffs = QBCore.Functions.HasItem('handcuffs')
if not handcuffs then
    QBCore.Functions.Notify("You don't have handcuffs", "error")
    return
end

Vehicle Spawn Issues

  • Verify spawn point coordinates are correct
  • Check if vehicle models exist in the server
  • Ensure proper permissions for vehicle spawning

Evidence System Not Working

-- Debug evidence collection
RegisterNetEvent('qb-policejob:debug:evidence', function()
    local evidence = MySQL.query.await('SELECT * FROM police_evidence ORDER BY created_at DESC LIMIT 10')
    for i = 1, #evidence do
        print("Evidence ID: " .. evidence[i].id .. ", Type: " .. evidence[i].type)
    end
end)

Debug Commands

-- Check player police status
/checkpolice [player_id]
 
-- Force jail player (admin only)
/forcejail [player_id] [time] [reason]
 
-- Clear all evidence (admin only)
/clearevidence
 
-- Toggle police radar
/radar

Performance Optimization

  1. Evidence Cleanup: Regularly clean expired evidence from database
  2. Alert System: Limit alert frequency to prevent spam
  3. Vehicle Management: Despawn unused police vehicles automatically
⚠️

Test all arrest and evidence systems thoroughly in a development environment before deploying to production.
