This project was my attempt at rewriting DarkRP in a more generalised, clean and object oriented way. It's got most of the basics done, but if you look at the issues tab you'll see there's much more to be done to get it into a complete state.
In the gamemode's current state, map data isn't provided by the server in any way. You need to download the map data from here and place it in your game's data folder (garrysmod/data/rpgm/map_dumps/map_complete.json). If you fail to do this, expect the gamemode to spam errors repeatedly as the minimap depends on it.
This project is dead, feel free to fork it and make it work to your liking, but please follow the license and make sure to credit me.
If you want to take it upon yourself to finish this or maintain it then go ahead, I won't stop you. Make a pull request and I'll review what you've got and accept it when it's ready 😁.
