i want to make a command that only can the server owner use (/makeleader [ID] [Gang]) so and the leader should do /makeofficial to make a player an official gang member. /removeofficial to remove the player. /makeog to make the player OG /removeog to remove the og rank , /makecoleader [ID]. and when someone is the leader of a gang or coleader / Member... the player should can use the gangcars. so my question is how to make a command like this and how to make cars only for a gang. i want to create a gangster RP mod.
