I want To Make Something Run ClientSided

[Weaved23]

So Im Making a New hitbox Module That Works Just Fine. But I want To make A Function Run Client Sided. I Tried Multiple Ways But It Doesnt Work. Here Is My Script:

local module = {}
module.__index = module

function module.new()
	return setmetatable({
		Size = Vector3.new(6,6,6),
		CFrame = CFrame.new(0,0,0),
		Offset = CFrame.new(0,0,0),
		DetectionMode = "Normal",	
		Visualizer = true,

		Box = nil,
		newBox = nil,

		Touched = GoodSignal.new(),

		Hitlist = {},

		Connection = nil,

		OverlapParams = OverlapParams.new()

	}, module)
end

function module:Visualize()
	local cframetype = typeof(self.CFrame)

	local pointcframe

	if cframetype == "CFrame" then
		pointcframe = self.CFrame
	elseif cframetype == "Instance" then
		pointcframe = self.CFrame.CFrame
	end

	if self.newBox then
		self.newBox.CFrame = pointcframe * self.Offset
	end

	if self.Box then
		self.Box.CFrame = pointcframe * self.Offset

		local dist = (self.OldCFrame.p - (pointcframe * self.Offset).p ).Magnitude
		
		warn(dist)
		
		if dist > .2 and self.OldCFrame ~= self.Box.CFrame then
			self.newBox = Instance.new("Part", workspace.Terrain)
			self.newBox.Name = "Visualizer"
			self.newBox.Size = self.Size
			self.newBox.Material = Enum.Material.ForceField
			self.newBox.CFrame = pointcframe * self.Offset
			self.newBox.Color = Color3.fromRGB(255,0,0)
			self.newBox.CanCollide = false
			self.newBox.Anchored = true
			self.newBox.Massless = true

			if not self.Visualizer then
				self.newBox.Transparency = 1
			else
				self.newBox.Transparency = .3
			end

			game.Debris:AddItem(self.newBox, .2)
		end
	else
		self.Box = Instance.new("Part", workspace.Terrain)
		self.Box.Name = "Visualizer"
		self.Box.Size = self.Size
		self.Box.Material = Enum.Material.ForceField
		self.Box.CFrame = pointcframe * self.Offset
		self.Box.Color = Color3.fromRGB(255,0,0)
		self.Box.CanCollide = false
		self.Box.Anchored = true
		self.Box.Massless = true
		self.Box.Locked = true

		local Hightlight = Instance.new("Highlight", self.Box)
		Hightlight.Name = "Hightlight"
		Hightlight.FillTransparency = 1
		Hightlight.OutlineColor = Color3.fromRGB(223, 0, 0)
		Hightlight.OutlineTransparency = 0
		Hightlight.Adornee = self.Box

		if not self.Visualizer then
			self.Box.Transparency = 1
		else
			self.Box.Transparency = .1
		end
	end

	self.OldCFrame = self.Box.CFrame
end

function module:Cast()
	local cframetype = typeof(self.CFrame)

	local pointcframe

	if cframetype == "CFrame" then
		pointcframe = self.CFrame
	elseif cframetype == "Instance" then
		pointcframe = self.CFrame.CFrame
	end

	local partsinbounds = workspace:GetPartBoundsInBox(pointcframe * self.Offset, self.Size, self.OverlapParams)

	for i, hit in pairs(partsinbounds) do
		local Enemy = hit:FindFirstAncestorOfClass("Model") or hit.Parent
		local Humanoid = Enemy:FindFirstChildOfClass("Humanoid")

		if self.DetectionMode == "Normal" and Enemy and Humanoid and not table.find(self.Hitlist, Enemy) then
			table.insert(self.Hitlist, Enemy)

			self.Touched:Fire(Enemy, Humanoid)

		elseif self.DetectionMode == "HitParts" then
			self.Touched:Fire(Enemy)
		end
	end
end

function module:Start()
	task.spawn(function()
		self.Connection = game:GetService("RunService").Heartbeat:Connect(function()
			self:Visualize()
			self:Cast()
		end)
	end)
end

function module:Stop()
	self.Connection:Disconnect()
	self.Touched:DisconnectAll()

	self.Hitlist = {}

	if self.Box then
		self.Box:Destroy()
	end

	if self.newBox then
		self.newBox:Destroy()
	end
end

return module

You can use a RemoteEvent to communicate between the Server and the Client, aswell as send parameters and other information to easily. You can learn more about RemoteEvents and their usage here: RemoteEvent | Documentation - Roblox Creator Hub

Use RemoteEvent to do that.

I know But I’ve Tried Doing That Multiple Times. My Hitbox Duplicates EVEN If the self.Box Exists. I cant Seem To do It clientsided. Its Really Hard.

[walmartgamchair (Nico)]

Have you tried removing the hitbox from the server, and only keeping it on the client? This may be the cause to the duplicate hitbox.

[Weaved23]

Yes i Exactly Did that. But I dont Know How to do it Thats The Problem.

[walmartgamchair (Nico)]

You can use :Destroy() or game.Debris:AddItem(hitbox) to delete the hitbox on the Server, but clone it on the Client to preserve it. Alternatively, you could have a remote that deletes it for everyone except you. (I’ve explained RemoteEvents on my previous post.)

Thank You Soo Much! I Will Try It Out Right Now
