Hi, I am back, sorry about inactivity, Today i have a question about how do i get if a player is within 7 studs of a object, I am making a microphone, and therefore i dont want everybody that chats putting a message on the screen. The script is inside the actual microphone object, Here is my code:

01game.Players.PlayerAdded:connect(function(player)
02    -- when `player` joins the game, start listening for their chatting
03    player.Chatted:connect(function(message)
04        -- and each time they chat, do stuff with `player` and `message`
05        processCommand(player, message)
06    end)
07end)
08function processCommand(speaker, message)
09    -- if someone chatted "whoami"
10    local playerW7s = true --i dont know how to get if a player is within 7 studs of a object
11    print("Checking if player is within 7 studs..")
12    if(playerW7s == true) then
13        local msg = Instance.new("Message", game.Workspace)
14 
15        msg.Text = message
16        wait(5)
17        msg:Destroy()
18 
19end
20end

Please help, thanks

That's a pretty cool idea, FunzreyAlt!

FearMeIAmLag, yourchicken, and crazycittycat have all addressed the key issue, but in addition to their collective advice, I'll offer some further refinements.

01--Personally, I think you should define functions that will be used later in the script before rather than after the block that they are used in.
02 
03microphone = --path to the microphone
04distance = 7 --distance in studs for microphone to activate
05 
06function processCommand(speaker, message)
07    if message:lower() == "whoami" then --works for "WHOAMI", "WhoAmI", "whoamI", etc..
08    if (speaker.Character.Torso.Position - microphone.Position).magnitude <= distance then
09            local msg = Instance.new("Message", game.Workspace)
10            msg.Text = message                                  
11            wait(5)
12            msg:Destroy()
13    end
14end
15 
16game.Players.PlayerAdded:connect(function(player)
17    player.Chatted:connect(function(message)
18        processCommand(player, message)
19    end)
20end)

In a future, more advanced version of this script you'll want to use a coroutine to create and destroy the message, and you'll want to check that the player has a Torso (i.e. exists in the physical world) before testing for distance. duckwit 1404 — 9y

Duckwit, it wont work, I tried typing Whoami WHOami, etc. and it wont say anything. so its not tested funzrey 58 — 9y

There was a typographical error. I wrote "=" in the conditional rather than "==", I've fixed it now. It's always assumed on ScriptingHelpers that you can test things for yourself. We're not here to script for you, but to get you set in the right direction. duckwit 1404 — 9y

23-- btw your script cleaning is horrendous. 
24-- [[ What .magnitude basically does is find if your user is closer than x studs, by calculating how far
25point a is from point b. ]] --

You could use magnitude to check the distance of the player's torso from the microphone. Of course you will have to keep looping over the player whenever they move in order to update their position and you will have to change the paths to the mic and player objects as this is just an example.

1if (player.Character.Torso.Position - workspace.Mic.Position).magnitude <= 7 then
2    --display the message
3    --destroy the message
4end

One does not need to constantly refresh the player's position - you can check the position of the player only when they chat. Much more efficient. duckwit 1404 — 9y

I suggest using tabs. Its much cleaner and easier to edit. This was fully tested by me and one of my friends. It should work perfectly and they should see the message if the speaker is in 7 studs of the microphone. If your microphone is not a model then change the mic:GetModelCFrame().p to mic.Position
