How can you equip a tool using a scroll wheel

Help and Feedback Scripting Support
#1

now i really dont know how to equip a tool using a scroll wheel, its it even possible to make a script to do it?
i have tried to research about it, but i dont see thing that can help

#2

No, unfortunately to the best of my knowledge, you cannot define the scroll wheel in Enum.Keycode.

#3

The scroll wheel is automatically part of the Roblox game play as a zoom in/out tool.
If you want to use it for other things in UserInputService then try this out:

Even though mouse is deprecated and shouldn’t be used, I know that Mouse | Roblox Creator Documentation exists, and so does Mouse | Roblox Creator Documentation. Use those to change the tool depending on which is which.

This is how far I was able to get it:

--LocalScript inside StarterCharacterScripts
local Players = game:GetService("Players") 

local Player = Players.LocalPlayer 
local Character = script.Parent 
local Humanoid = Character:WaitForChild("Humanoid")
local Mouse = Player:GetMouse()

local equipped = 0
local max = 0

function GetTools(equippedTool)
	local tools = Player.Backpack:GetChildren()
	table.insert(tools, equippedTool)
	table.sort(tools, function(a, b) --sort by name
		return a.Name < b.Name 
	end)
	return tools 
end

function Equip(equippedTool)
	local tools = GetTools(equippedTool) 
	local index = (equipped % #tools)+1
	Humanoid:EquipTool(tools[index])
end

function Update(direction)
	local equippedTool = Character:FindFirstChildWhichIsA("Tool") 
	if not equippedTool then return end --only run code if they have a tool equipped
	equipped += direction 
	Equip(equippedTool)
end

Mouse.WheelForward:Connect(function()
	Update(1)
end)

Mouse.WheelBackward:Connect(function()
	Update(-1)
end)

Three issues:

  1. The scrolling wheel index isn’t in sync with other methods of equipping tools(example directly clicking a tool)
  2. WheelForward/WheelBackward also zooms in and out the player camera, couldn’t find how to disable that feature while keeping the camera as it is.
  3. Sorting misbehaves when multiple tools have the same name.

you can do that but you don’t use Enum.Keycode you still use UserInputService but in a different way, Check this

local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local HRP = Character:WaitForChild("HumanoidRootPart")
local Mouse = Player:GetMouse()
local Backpack = Player:WaitForChild("Backpack")
local Tools = Backpack:GetChildren()
local Camera = workspace.CurrentCamera

local CameraMinZoom = Player.CameraMinZoomDistance
local CameraMaxZoom = Player.CameraMaxZoomDistance

local Toggle = false

local function ChangeZoom()
	if Toggle then
		Player.CameraMinZoomDistance = CameraMinZoom
		Player.CameraMaxZoomDistance = CameraMaxZoom
	elseif not Toggle then
		local CurrentZoom = (Camera.CFrame.Position - HRP.CFrame.Position).Magnitude
		Player.CameraMinZoomDistance = CurrentZoom
		Player.CameraMaxZoomDistance = CurrentZoom
	end
end
ChangeZoom()

local function SortTools()
	table.sort(Tools, function(Left, Right)
		return Left.Name < Right.Name
	end)

	for _, Tool in ipairs(Tools) do
		Tool.Parent = nil
	end

	for _, Tool in ipairs(Tools) do
		Tool.Parent = Backpack
	end
end
SortTools()

local function OnToolAdded(Child)
	if Child:IsA("Tool") then
		if table.find(Tools, Child) then
			return
		end
		
		table.insert(Tools, Child)
		SortTools()
	end
end

local function OnMouseScroll(Context)
	local Tool = Character:FindFirstChildOfClass("Tool")
	if Tool then
		local Index = table.find(Tools, Tool)
		if Index then
			if Context == "Up" then
				if Index == #Tools then
					Tool = Tools[1]
				else
					Tool = Tools[Index + 1]
				end
			elseif Context == "Down" then
				if Index == 1 then
					Tool = Tools[#Tools]
				else
					Tool = Tools[Index - 1]
				end
			end
			Humanoid:EquipTool(Tool)
		end
	elseif not Tool then
		if Context == "Up" then
			Tool = Tools[1]
		elseif Context == "Down" then
			Tool = Tools[#Tools]
		end
		Humanoid:EquipTool(Tool)
	end
end

local function OnMouseScrollUp()
	OnMouseScroll("Up")
end

local function OnMouseScrollDown()
	OnMouseScroll("Down")
end

local function OnKeyDown(Key)
	if Key:lower() == "c" then
		Toggle = not Toggle
		ChangeZoom()
	end
end

Mouse.KeyDown:Connect(OnKeyDown)
Mouse.WheelForward:Connect(OnMouseScrollUp)
Mouse.WheelBackward:Connect(OnMouseScrollDown)
Backpack.ChildAdded:Connect(OnToolAdded)
Character.ChildAdded:Connect(OnToolAdded)

Here’s a version with all of those issues resolved, the current scrolling position is synchronised with other ways in which a tool can be equipped i.e; manually clicking on the icon, manually pressing the number key which the tool is bound to, picking up a tool with its “ManualActivationOnly” property disabled etc. Scrolling through tools works when two or more tools share the same name. The script incorporates a camera lock feature which is bound to the “c” key (it’s enabled by default), this lock prevents the camera from zooming but allows all other camera actions to take place. Finally, equipping a tool isn’t required, if a tool isn’t equipped and the player attempts to scroll upwards through their tools then they will equip the tool in the first slot, similarly, if a tool isn’t equipped and the player attempts to scroll downwards through their tools then they will equip the tool in the final slot.
