Yes, you will only have to adapt the point at which a vehicle is assigned and the mod is called to do so. Specifically in the xex_rewards:generatePlate handler. In the main-c.lua file.
I received this error
script:es_extended] [WARNING] Server callback โesx_vehicleshop:giveVehicleโ does not exist. Please Check The Server File for Errors!
Hello and thank you very much!! I didnโt have it in mind but with the current version it could easily be adapted to this framework. Feel free to do a PR and I will gladly accept it.
