How do you test for players near you?

This is actually more tricky than you think,

Expect a long answer.

• First,

To get a distance from one object to/from another, you can use Magnitude. Example,

local part1 = workspace.Part1
local part2 = workspace.Part2

local Distance = (part1.Position-part2.Position).Magnitude
print(Distance)

Same concept, but we'll be using Character's Torsos.

• Second,

We need to get all the players and check if the Distance is less than a certain number. I would suggest a pairs loop. A pairs loop will loop through a table getting all the values. If we want to loop through all the players, we can use :GetPlayers to return a table and use a pairs loop on that table! Example,

for i,player in pairs(game.Players:GetPlayers()) do
    print(player.Name)
end

That will print all the players' names.

• Third

To get the Torsos of all these players, we first need to get the characters. Lucky for us, there's a neat property of the players that allows us to get the Character rather easily. After we get a player, we just need to use .Character to get the character. After that, we can get the Torso. Example,

for i,player in pairs(game.Players:GetPlayers()) do
    local Torso = player.Character.Torso
end

• Fourth,

Use a LocalScript and a Loop to constantly check if the Local Player is near another Player. It's important to use Local Scripts when you can, and when working with PlayerGui. Local Scripts don't work in workspace so use StarterPack or something :3

• Combining What We've Learned,

After Combining all these things, we should get a script similar to this,

-- Local Script in StarterPack or something

-- Variables
local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local Torso = char:WaitForChild("Torso")
local Social = blah.blah -- Fix this
local MaxDistance = 20 -- Distance before social goes up

-- Function
local function CheckPlayers()
    for i,player in pairs(game.Players:GetPlayers()) do
        local otherTorso = player.Character.Torso
        local Distance = (Torso.Position-otherTorso.Position).Magnitude
        if (Distance <= MaxDistance) then
            return true
        end
    end
    return false
end

-- Main Loop
while wait(1) do
    if CheckPlayers() then
        Social.Value = Social.Value +2 -- Fix this :3
    end
end

Warning, this may not work. If this doesn't work, please tell me the error and I'll fix this as soon as I get the chance.

Edit,

We're currently getting our own torso, so the magnitude would be 0, which is less than MaxDistance. Let's just make sure v doesn't equal our player.

-- Local Script in StarterPack or something

-- Variables
local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:wait()
local Torso = char:WaitForChild("Torso")
local Social = blah.blah -- Fix this
local MaxDistance = 20 -- Distance before social goes up

-- Function
local function CheckPlayers()
    for i,player in pairs(game.Players:GetPlayers()) do
        if player ~= plr then
            local otherTorso = player.Character.Torso
            local Distance = (Torso.Position-otherTorso.Position).Magnitude
            if (Distance <= MaxDistance) then
                return true
            end
        end
    end
    return false
end

-- Main Loop
while wait(1) do
    if CheckPlayers() then
        Social.Value = Social.Value +2 -- Fix this :3
    end
end

I hope I helped you!

Good Luck!
