How do I get the user who clicked a SurfaceGui?

You have to add the SurfaceGui to their PlayerGui, and set its Adornee property, like so:

SurfaceGui.Adornee = Workspace.Brick

This will allow you to access the Player that has clicked the SurfaceGui, but any changes a Player makes to the SurfaceGui's contents (i.e. scrolling) will only appear for them.

Use what adark said.

Put the SurfaceGui in StarterGui, then set Adornee to brick. Then in a LocalScript in the Gui do this

local block = workspace.NAMEOFBLOCKHERE
script.Parent.Adornee = block
script.Parent.BUTTON.MouseButton1Down:connect(function()
print(game.Players.LocalPlayer.Name)
end)

gg no re

Use a LocalScript, perhaps in Backpack, or PlayerGui

local player = game.Players.LocalPlayer

local surfaceGui = player.PlayerGui.SurfaceGui

local block = Workspace.Block


surfaceGui.Adornee = block


surfaceGui.TextButton.MouseButton1Up:connect(function()

    -- Do Stuff --

end)

Ofcourse, this will only be visible to the local player.

If you wanted it visible to other player's, you'd have to make a system that updates the information on the surface gui, for each player. Or something along them lines.

There's not really any way that I know how to do this, but it is really easy using ClickDetectors which serve close to the same purpose. Assuming that your hierarchy would look something like this:

• Part -- SurfaceGui --- TextButton/TextLabel -- ClickDetector --- Script

The script inside of the ClickDetector would look something like this:

script.Parent.MouseClick:connect(function(player)
    print(player.Name .. " pressed me!")
end)
