How can I get to someone in Player through a GUI?

I'm making some game, and when someone clicks a GUI, I don't want them to die, so I want to load their character, but I only know how to get to them in Workspace.

From the gui you can use a localscript with the following line to get the player

local player = game.Players.LocalPlayer

You can also just use

local player = game.Players:FindFirstChild('Name of Player') if you want to get someone whose name you have.

If you're using a LocalScript, then game.Players.LocalPlayer will reference the player.

However, if you aren't, there's a simple solution.

m = game.Workspace.Player:GetPlayerFromCharacter() -- change "game.Workspace.Player" to variable for the actual player

m:LoadCharacter()

Hope I could be of help; good luck!

If you are using a LocalScript, you will be able to access the current player by the LocalPlayer property of the Players service.

local plr = game.Players.LocalPlayer

plr.Character:BreakJoints() -- kill character
