How do I get multiple targets closest with magnitude?

Help and Feedback Scripting Support
#1

Basically I’m trying to make a combat system and instead of it only hitting the closest #1 player or dummy I want it to hit multiple targets, is there anyway how I can do this? function I’m using is below

local function GetClosest()
	local Character = LocalPlayer.Character
	local HumanoidRootPart = Character and Character:FindFirstChild("HumanoidRootPart")
	if not (Character or HumanoidRootPart) then return end

	local TargetDistance = math.huge
	local Target

	for i,v in ipairs(AliveFolder:GetChildren()) do
		if v ~= AliveFolder:FindFirstChild(LocalPlayer.Name) and  v:FindFirstChild("HumanoidRootPart") then
			local TargetHRP = v.HumanoidRootPart
			local mag = (HumanoidRootPart.Position - TargetHRP.Position).magnitude
			if mag < TargetDistance then
				TargetDistance = mag
				Target = v
			end
		end
	end

	return Target
end

More importantly, if I could only get the closest infront of my player, and not behind

To get the players onfront of your player after a magnitude check, use :dot().

As for your other problem, can you tell me where AliveFolder is located? that might be the issue.

The best way is to use Roblox spatial queries.

You can easily get a table of all the parts within given box.
Alternatively, you can also use GetPartBoundsInSphere().

Try to make some competition-like system

function getclosesttorso()
local torso,mag = nil,0
local Character = LocalPlayer.Character
	local HumanoidRootPart = Character and Character:FindFirstChild("HumanoidRootPart")
	if not (Character or HumanoidRootPart) then return end
for _,v in ipairs(AliveFolder:GetChildren()) do
if v ~= AliveFolder:FindFirstChild(LocalPlayer.Name) and v:FindFirstChild("HumanoidRootPart") then
local currmag = (HumanoidRootPart.Position-v.HumanoidRootPart).Magnitude
if currmag > mag then
torso = v.HumanoidRootPart
mag = currmag
end
end
end
return torso,mag
end

There’s no issue, as of right now I have nobody to test with so I have 2 dummies kept in the alive folder. When players join their characters are parented under the folder

#6

would this return multiple? or just the closest, i want it to detect the multiple in which i can deal dmg to each

#7

sorry just the closest.

Yeah, that’s what the current script I posted is doing. just want to know a way in which I can detect multiple ithat are close rather than just getting one.
I also tried your code and I got an error, but It does the exact same thing as the function I posted so it’s alright.

#9 
local function GetClosest()
	 -- how many studs can the player hit in front
	local range = 5

	-- divide the range by 2
	range /= 2

	-- get the players position
	local position = LocalPlayer.Character.PrimaryPart.Position

	-- move the position in front of the character
	position += LocalPlayer.Character.PrimaryPart.CFrame.LookVector * range

	-- create a empty table to store the targets
	local targets = {}

	-- loop all characters alive
	for i, character in ipairs(AliveFolder:GetChildren()) do
		-- if the character is the same as the local players character then skip
		if character == LocalPlayer.Character then continue end

		-- if the character is out of range then skip
		if (character.PrimaryPart.Position - position).magnitude > range then continue end
		
		-- add the character to the target table
		table.insert(targets, character)
	end

	-- return the targets back to the caller
	return targets
end

If you don’t need to use magnitude using WorldRoot | Documentation - Roblox Creator Hub would be a better option

Exactly what I was looking for, thank you
