Troubleshooting

Common Issues

Attachments Not Working

-- Check weapon compatibility
function CheckWeaponCompatibility(weaponHash, attachmentType)
    local weaponName = GetWeaponNameFromHash(weaponHash)
    local attachmentConfig = Config.Attachments[attachmentType]
    
    if not attachmentConfig then
        print("Attachment config not found:", attachmentType)
        return false
    end
    
    for i = 1, #attachmentConfig.compatible_weapons do
        if attachmentConfig.compatible_weapons[i] == weaponName then
            return true
        end
    end
    
    print("Weapon not compatible:", weaponName, "with", attachmentType)
    return false
end

Degradation Issues

Verify weapon serial tracking system
Check degradation rate calculations
Ensure proper inventory integration

License Verification Problems

-- Debug license checking
RegisterCommand('checklicense', function()
    QBCore.Functions.TriggerCallback('qb-weapons:server:getLicense', function(license)
        if license then
            print("License type:", license.license_type)
            print("Expires:", license.expires_date)
            print("Status:", license.status)
        else
            print("No weapon license found")
        end
    end)
end)

Debug Commands

-- Give weapon attachment
/giveattachment [player_id] [attachment_type]
 
-- Repair weapon
/repairweapon [player_id] [weapon_serial]
 
-- Check weapon durability
/checkdurability [weapon_serial]
 
-- Issue weapon license
/issuelicense [player_id] [license_type]

⚠️

Test weapon mechanics thoroughly to ensure proper balance between realism and gameplay enjoyment.
