Hello, the function that gets the nearest player’s HRP returns nil.

function GetNearestPlayer()
	local test = game.Workspace:GetChildren()
	
	local max_dist = 50
	local target = nil
	
	for _,v in pairs(test) do
		if v:IsA("Model") and game.Players:FindFirstChild(v) then
			
			local test_hrp = v:FindFirstChild("HumanoidRootPart")
			
			if (hrp.Position - test_hrp.Position).magnitude < max_dist then
				target = test_hrp
			end
		end
	end
	print(target)
	return target
end

Hello zCrxtix!

Here is a quick little function I just wrote up to find the nearest player to a supplied Vector3 position.

local function getnearestplayer(position)
	assert(typeof(position) == "Vector3","Position must be a Vector3!")
	--
	local nearestplayer = nil
	local nearestdistance = math.huge
	--
	for i,v in pairs(game.Players:GetPlayers()) do
		if v.Character then
			if v.Character:FindFirstChild("HumanoidRootPart") then
				local position = (v.Character.HumanoidRootPart.Position - position).Magnitude
				if position < nearestdistance then
					nearestdistance = position
					nearestplayer = v
				end
			end
		end
	end
	--
	return nearestplayer,nearestdistance
end

--> Use:
---> getnearestplayer(Vector3)

This gives me an error “Argument 2 missing or nil”. I edited your code:

local function GetNearestPlayer()
	local nearestplayer = nil
	local nearestdistance = math.huge

	for i,v in pairs(game.Players:GetPlayers()) do
		if v.Character then
			if v.Character:FindFirstChild("HumanoidRootPart") then
				local position = (v.Character.HumanoidRootPart.Position - hrp.Position).Magnitude
				if position < nearestdistance then
					nearestdistance = position
					nearestplayer = v
				end
			end
		end
	end

	return nearestplayer,nearestdistance
end

And I appreciate you writing that for me, but I’d prefer to use my own code.
