Best way to make an attack hitbox? Touched is unreliable.

Hey! I just finished fixing this script after a unreasonably long time and I found out two bugs.

1. The damage will randomly be high (triple the amount). My button script does make the hitbox be created 3 times, but each time it's 18 instead of 6.

2. Touched event only fires when parts are moving (I know this is how it works, but now I can't use it for this)

The Touched event can't be used in this situation because if the victim is standing still, they take no damage. People have suggested Raycasting or Region3, but it seems like it's not only more time consuming, but kinda hard to use (along with it being a bit more laggy if I was to make every hitbox Raycasting in an 8 player game). I've tried Unanchoring the hitbox so it can detect when it hits a player, but this seems like it would cause minor problems with the hitbox not being in the perfect spot. All of this and I still have a minor problem with damage and why it's being done more than once. Does anyone know a better way to make a hitbox that avoids these problems? Heres my current code:

The damage:

local part = game.ReplicatedStorage.ClassData.Bloxxer.BloxxerSword:Clone()
local P = script.Parent
local fire = game.ReplicatedStorage.MoveSetFires

local A = P.ATK
local AF = fire.Attack
local A1 = P.AB1
local A1F = fire.AB1
local A2 = P.AB2
local A2F = fire.AB2
local RJ = P.REJ
local RJF = fire.Rejuvinate
local CORE = P.BTZ
local CF = fire.Core

	local Attackcd = false
	local AtCD = .8


		
		local function createhitbox(size1, size2, size3, damage, tim, offset, player)
			local sword = player.Character:WaitForChild("BSword", math.huge)
 			local hit = Instance.new("Part")
			hit.Size = Vector3.new(size1,size2,size3)
			hit.Color = Color3.new(200,0,0)
			hit.Transparency = .6
			hit.CFrame = player.Character.HumanoidRootPart.CFrame:ToWorldSpace(CFrame.new(0,0,offset))
			hit.CanCollide = false
			hit.Parent = workspace
			local destroy = coroutine.create(function()
				wait(tim)
				if hit then
				hit:Destroy()
				end
			end)
		coroutine.resume(destroy)
	
			hit.Touched:Connect(function(h)
				
				if h ~= player.Character.Humanoid or player.Character.HumanoidRootPart or player.Character then
				local humanoid = h.Parent.Humanoid or h.Parent:FindFirstChildOfClass("Humanoid")
				print(h)
				humanoid.Health = humanoid.Health - damage
				hit:Destroy()
				end
			end)
		end


			print("okok")
	AF.OnServerEvent:Connect(function(player)
		if player then
	--the hitbox
	createhitbox(3.1, 2.45, 7.25, 6, .1, -8, player)
		
	end
end)

The other script is the one that fires the event when the player clicks, but I don't think I need to post it.

Thanks for reading.

I’m not sure why you feel raycasting is expensive enough to sacrifice for better UX. You can use Swordphin123’s Raycast Hitbox Module to ease your work. You can also see concerns regarding how expensive the raycasting is and it’s usability on the thread.

The cons of raycasting repeatedly are not strong enough to sacrifice essential game mechanics for.
