I have seen so many people face issues with GuiObject mouse events not firing, leaving their UI sad

Extend MouseEnter/MouseLeave (GuiObject) to fire in more scenarios
GuiObject.MouseLeave not firing as expected [Only occurring with the input device being mouse]
.MouseEnter/.MouseLeave not fired on UI Frames when scrolled - #11 by 7eoeb
This only works with ScreenGuis, if you need reliable Mouse Events for SurfaceGui, click here

Roblox’s MouseEvents (BAD)
My MouseEvents (GOOD)
Another Comparison
The main advantage: ScrollingFrames
The most common report is that it doesn’t fire when scrolling through frames. This is because the engine only checks wether the user is hovering over a GuiObject every time the mouse moves, not every frame. My version fixes this (shown in the first video).
Other advantages
- No more issues where MouseLeave randomly doesn’t fire
- Works with CoreGui open
How to use
Just require the module and call the .new() function, passing in the GuiObject. You’ll get two RBXScriptSignals (mouseEnter, mouseLeave).
Example code:
local ScrollingFrame = script.Parent
local MouseEvents = require(script.MouseEvents)
local TweenService = game:GetService("TweenService")
local info = TweenInfo.new(0.15)
for _, v in ScrollingFrame:GetChildren() do
if v:IsA("ImageButton") then
local enter, leave = MouseEvents.new(v)
enter:Connect(function()
TweenService:Create(v, info, {BackgroundColor3 = Color3.fromRGB(235, 235, 235)}):Play()
TweenService:Create(v.UIStroke, info, {Thickness = 2}):Play()
end)
leave:Connect(function()
TweenService:Create(v, info, {BackgroundColor3 = Color3.fromRGB(255, 255, 255)}):Play()
TweenService:Create(v.UIStroke, info, {Thickness = 0}):Play()
end)
end
end

A while ago I implemented this module into my own game, and want to link it here so you can see what it is like. Link: robloxOS
