How to Access other player

[pine fjord]

I am trying to make a tool. A coffee. And if you left click on a player in a set range, it should make a UI show on his screen. As far as I know I need a local script for the tool, then it fires a RemoteEvent which then activates a script to make the UI show for the „target“ person. The UI will look like spilled coffee. How can I 1st find out who is the 2nd player. 2nd how can I acces HIS UI?

You can use a remote event from the client to the server and another one from the server to the other player. Like this:
Player1

RemoteEvent:FireServer(Player2)

Server

RemoteEvent.OnServerEvent:Connect(function(Player)
   RemoteEvent:FireClient(Player2, Player)
end)

Player2

RemoteEvent.OnClientEvent:Connect(function(Player)
-- make some ui changes to player2 (player1's target)
end)

you can do

player.PlayerUi

or smth like that

so I make a local script inside of the tool with a function that activates a remote event when the player2 gets clicked. Then I make a server script on ServerScriptService with the 2nd thing you said but where do I put the last parts?

And how do I make the target? Does the game know that player 2 is the target or do I have to definate it first?

the last part you can put in a local script in starterplayerscripts or startercharacterscripts or backpack. anywhere where it runs

or startergui
