How to prevent MouseEnter from being fired when a frame is above them?

Help and Feedback Scripting Support
#1

Unsure if I should report this as a bug (would, but too lazy to make a repro atm) but as far as I’m aware this has always happened, and it’s incredibly infuriating, and not how I believe MouseEnter should work.

I have a bunch of buttons, each with MouseEnter events connected to them. However, notable flaws are that they still work even if a frame is above them, causing unwanted problems

Any possible solutions?? I don’t want to do

if not frame.Visible then

As I use the MouseEnter function is a variety of different scripts for just the 1 case of buttons here. Example being, 1 script handles the hover sound effect, another handles the hover frame info.

Bumping this, I’m looking for a solution now… Were you able to find a solution @NinjoOnline ?

Second bump… Were any of you guys able to find a solution?

#4

Dang unfortunately I don’t quite remember. It wasn’t an overall solution but just a case specific solution I think.

#5

I think if you set Frame.Active to true, that should work.

#6

That’s what I tried, and I’m sure he did too, but it didn’t work.

#7

Is visible also true? That may be the problem.

#8

Yes visible is on, active is on, and interactable is on, yet the frames below it still register MouseEnter

I wrote you some code. You’ll need to change it to fit your application though. Here’s how it works:

  • We keep track of all ‘depths’ (how deep a frame is nested)
  • We keep track of all hovered over frame
  • We select the highest hovered frame
  • When we leave it, we try select the next highest hovered frame (if there’s any left)

local topFrame, topFrameDepth = nil, 0

local hovered = {}
local cached = {}

local function getFrameDepth(f)
	if not cached[f] then
		local depth = 0
		local parent = f
		repeat
			depth = depth + 1
			parent = parent.Parent
		until parent:IsA("ScreenGui") or not parent
		cached[f] = depth
	end
	return cached[f]
end

local function updateTopFrame()
	-- Sort hovered frames by depth in descending order
	table.sort(hovered, function(a, b)
		return getFrameDepth(a) > getFrameDepth(b)
	end)

	-- Set the new top frame
	if #hovered > 0 then
		local newTopFrame = hovered[1]
		local newTopFrameDepth = getFrameDepth(newTopFrame)

		if newTopFrame ~= topFrame then
			if topFrame then
				topFrame.BackgroundColor3 = Color3.new(1, 1, 1)
			end

			topFrame = newTopFrame
			topFrameDepth = newTopFrameDepth
			topFrame.BackgroundColor3 = Color3.new(0.5, 0.5, 0.5)
		end
	else
		if topFrame then
			topFrame.BackgroundColor3 = Color3.new(1, 1, 1)
		end

		topFrame = nil
		topFrameDepth = 0
	end
end

for _, v in ipairs(script.Parent:GetDescendants()) do
	if v:IsA("Frame") then
		v.MouseEnter:Connect(function()
			if not table.find(hovered, v) then
				table.insert(hovered, v)
			end
			updateTopFrame()
		end)

		v.MouseLeave:Connect(function()
			local index = table.find(hovered, v)
			if index then
				table.remove(hovered, index)
			end
			updateTopFrame()
		end)
	end
end
