Connect/disconnect function when equipping/unequipping the tool

Help and Feedback Scripting Support
#1

I made a building tool, using which I can place and rotate a block. I have came to an issue though, unequipping the tool does not disable the script inside it, and while tool is still in the inventory of player, I still can place and rotate blocks.

It seems like the solution for that would be connecting and disconnecting functions when tool is equipped/unequipped, but I am not really familiar with connections.

Here is the script:

local ContextActionService = game:GetService("ContextActionService")
local players = game.Players
local player = players.LocalPlayer

local tool = script.Parent
local block = tool.Block
local holo = tool.BlockHolo
local mouse = player:GetMouse()

mouse.Move:Connect(function() -- Display
	local mousePosition = Vector3.new(math.round(mouse.Hit.Position.X), math.round(mouse.Hit.Position.Y), math.round(mouse.Hit.Position.Z))

	local target = mouse.Target
	local targetSurface = mouse.TargetSurface

	if targetSurface == Enum.NormalId.Top then
		holo.Position = mousePosition + target.CFrame.UpVector
	elseif targetSurface == Enum.NormalId.Bottom then
		holo.Position = mousePosition - target.CFrame.UpVector
	elseif targetSurface == Enum.NormalId.Front then
		holo.Position = mousePosition + target.CFrame.LookVector
	elseif targetSurface == Enum.NormalId.Back then
		holo.Position = mousePosition - target.CFrame.LookVector
	elseif targetSurface == Enum.NormalId.Right then
		holo.Position = mousePosition + target.CFrame.RightVector
	elseif targetSurface == Enum.NormalId.Left then
		holo.Position = mousePosition - target.CFrame.RightVector
	end

end)

local function RotateAndPlace(actionName, inputState, inputObject) -- Rotate
	if inputObject.KeyCode == Enum.KeyCode.R and inputState == Enum.UserInputState.Begin then
		holo.CFrame = holo.CFrame * CFrame.Angles(0, math.rad(90), 0)
	elseif inputObject.KeyCode == Enum.KeyCode.T and inputState == Enum.UserInputState.Begin then
		holo.CFrame = holo.CFrame * CFrame.Angles(0, 0, math.rad(90))
	elseif inputObject.UserInputType == Enum.UserInputType.MouseButton1 and inputState == Enum.UserInputState.Begin then
		local clone = holo:Clone()
		clone.Transparency = 0
		clone.Parent = workspace
		clone.Name = "Block"
		clone.CanCollide = true
		clone.Anchored = false
		local weld = Instance.new("WeldConstraint")
		weld.Parent = clone
		weld.Part0 = clone
		weld.Part1 = mouse.Target
	end
end

ContextActionService:BindAction("Rotate and Place", RotateAndPlace, false, Enum.KeyCode.R, Enum.KeyCode.T, Enum.UserInputType.MouseButton1)

I really need help with that. It would be quite nice if somebody explained how to Disconnect() functions properly.

I don’t think disconnecting and reconnecting functions would be the best way for such a bulky and important system. Maybe a Boolean-controlled value to check instead.

However, if you really want to use connections, here’s how you would do it:

--for your ContextActionService action
ContextActionService:UnbindAction("Rotate and place")

--for your Mouse.Move connection
local connection = mouse.Move:Connect(function()
    --your code
end)

--then...
connection:Disconnect()

Yeah this seems quite logical, but when I actually tried to UnbindAction, using the tool.Unequipped event, the placing part function broke even while tool was equipped

Nevermind, I managed to actually fix my issue. Thank you for your help!
