I have an error occur when a player joins a game when there is an ongoing round.
I have tried the local server simulation however that doesn’t give you the option of having a player join the game.
What I need is to be able to create a local server, have a player commence a round, and during that round have a new player join. Is that possible and I’m simply blind, or does roblox need a feature update?
Yeah you would allow players to register for a round, and then take the registered players and put them in the round. New players would then join and register for a round. I mean at this point it would circumvent this entire post. But this is how I handle mines. Ofcourse you don’t have to do it this way.
But other than CreatePlayer in the command bar… I’m unaware if you can add a new player while testing. Someone else might be able to go more indepth.
Im really sorry for asking such a useless question, I have found how to add a player on an ongoing simulation.
I simply need to click the simulation button on the server once again with the amount of new player I want to add.
Ahh you was talking about that. That would initially add the number of players you want. But it wouldn’t do it “during runtime”
Well, I need to simulate a server running a round of any gamemode. Then I want to simulate a player being added to that server during the runtime of the gamemode to troubleshoot some of the issues i am having.
Doing it the way you said should work. It’s essentially like opening a new Roblox client and having someone play. Where as CreateLocalPlayer I believe would just create a new player object without a new client. I’ve never used it before though. Anywho basically you solved your own question. 
I don’t wanna confuse you anymore than I have.
Not a useless question. And thank you for posting the solution! I didn’t think of this either.

Luckily I haven’t been looking that long.
