Hi everyone! I’ve been quite curious on how to create a mouse trail effect however, I’m not sure if it is possible. If you have any ideas on how to achieve this, please let me know. Thank you!

Interesting question!

I’ve never done such a thing, but the way I’d do it is to constantly be creating and fading out then removing ImageLabels where the mouse’s position is. You can get a mouse’s position by using local mouse = game.Players.LocalPlayer:GetMouse() to get the mouse and then the X value would be mouse.X while the Y value would be mouse.Y.

I could create the trail effect like so:

local imageId = "" -- you can put whatever mouse icon ID you want here
local mouseIcons = {} -- store icons here to remove as needed

while wait(.1) do
    if mouseIcons[5] ~= nil then
        mouseIcons[5]:Destroy() -- destroy the last value
    end
    for i = 1, 4 do
        if mouseIcons[i] ~= nil then
            mouseIcons[i + 1] = mouseIcons[i] -- shifting values down
            mouseIcons[i + 1].ZIndex -= 1 -- lower the layer
            mouseIcons[i + 1].Transparency -= .2 -- fade out
        end
    end
    local mouseIcon = Instance.new("ImageLabel")
    mouseIcon.Position = UDim2.new(0, mouse.X, 0, mouse.Y)
    mouseIcon.Image = imageId -- set the image
    mouseIcon.ZIndex = 6 -- this makes sure the newest one is on top
    mouseIcon.Parent = ScreenGui -- make sure you create a ScreenGui
    -- customize the size or anything of the image however you like here

    mouseIcons[1] = mouseIcon -- set as first value in the table
end

Edit:
You’ll also wanna make the default mouse invisible. To do this:

local UIS = game:GetService("UserInputService")
UIS.MouseIconEnabled = false

Edit 2:
Upon testing this on my end, this works pretty well, but the core mouse icon is jittery. To fix this, I would use RenderStepped to have one ImageLabel that is always right where the mouse’s position is.

local mouseIcon = Instance.new("ImageLabel")
mouseIcon.ZIndex = 7 -- make it higher zindex than all the other icons
-- same properties you've added before here

local RS = game:GetService("RunService")
RS.RenderStepped:Connect(function()
    mouseIcon.Position = UDim2.new(0, mouse.X, 0, mouse.Y)
end)
