I want to make a URL that when you go to, makes you join a specific server of a Roblox game.
I got a URL that sort of works. It opens the Roblox app and thats it, doesn’t put you in the server.
This is correct. The only other way which is REALLY untrustworthy would be running software applications that does it for you. That is a whole other can of worms that is not to be messed with, especially when it comes to running 3rd party applications on a computer.
