Troubleshooting

Common Issues

Vehicle Repairs Not Working


-- Check vehicle entity validity
if not DoesEntityExist(vehicle) then
    print("Vehicle entity does not exist")
    return
end
 
-- Verify repair permissions
local player = QBCore.Functions.GetPlayerData()
if player.job.name ~= "mechanic" or not player.job.onduty then
    print("Player not authorized for repairs")
    return
end

Modification Costs Not Updating

Verify modification cost configuration in config.lua
Check if vehicle model supports specific modifications
Ensure proper database table structure for tracking modifications

Parts Inventory Issues


-- Debug parts inventory
RegisterCommand('checkparts', function()
    local inventory = exports['qb-mechanicjob']:GetShopInventory('bennys')
    for part, quantity in pairs(inventory) do
        print(part .. ": " .. quantity)
    end
end)

Debug Commands


-- Repair vehicle instantly (admin only)
/fixveh
 
-- Add mechanic parts to inventory
/givepart [part_name] [quantity]
 
-- Check vehicle modification levels
/checkmods
 
-- Toggle mechanic duty
/mechduty

Performance Optimization

Damage Calculations: Optimize vehicle damage checking frequency
Part Inventory: Cache inventory data to reduce database queries
Vehicle Spawning: Implement proper vehicle cleanup and pooling

Always test vehicle modifications and repairs thoroughly to ensure they work correctly with your server’s vehicle system.
