Licenses#

Check whether a player holds a specific driving or skill license.

HasLicense (Client)#

The license check is initiated from the client using a server callback:

KOJA.Client.HasLicense(licenseName, callback)

Example

KOJA.Client.HasLicense('driver', function(has)
    if not has then
        print('No driver license')
    end
end)

License Names#

The name you pass must match what is stored in the framework's database.

How it Works#

Internally, KOJA.Client.HasLicense triggers the server callback koja-lib:HasLicense. The server then queries the framework:

• ESX — triggers the esx_license:checkLicense event
• QBCore — reads Player.PlayerData.metadata.licenses
• Custom — returns false by default (implement in CustomFramework.Server)

Implementing License Check for Custom Framework#

In editable/custom/framework_server.lua, the license check is handled by the koja-lib:HasLicense callback. If you use a custom framework you can override this by registering the callback yourself before koja-lib loads, or by modifying server/modules/licenses.lua.

Example for a custom framework:

-- In your own server script
KOJA.Server.RegisterServerCallback('koja-lib:HasLicense', function(source, licenseName, cb)
    local player = MyFramework.GetPlayer(source)
    if not player then return cb(false) end
    cb(player.hasLicense(licenseName))
end)
