Funny your name is BlackSpace because for my Group called Black Space I use a system Discord To Roblox.
^ Take note player not found because he was not found in-game.
What you will need is:
- An External DataBase
- An Discord Bot
When you kick players from Discord you add a new value to the database, passing by an API to convert the Username to RobloxID then when the DataBase has stored the data, make a while wait(5) do do check all players ID to see if they fit with the data send by the database if yes then kick the player, you can also add more values do it, example Kick Reason, etc…
To make sure I have a return to see if he was kicked I do if the player kicks then remove from Roblox the database value and make in the discord a check to see if its remove then the player got kicked if after 6 sec the Discord cmd check the RobloxID in the database is still here then its delete it and return a player not found.
So Discord to Roblox cmds don’t exist by Function you must pass by a DataBase.
I use FireBase, this may help you.
