MouseDetectors hover functions are buggy when the mouse hover them too fast

[USawAlex]

1. What do you want to achieve? ; Im trying to make a system where when a player hover the mouse over a certain cube, it enables a specific UI with the cube informations.

2. What is the issue? ; When the mouse hover the Cube too rapidly, it sometimes break and leave the UI enabled.

3. What solutions have you tried so far? : I tried to look onto the Developer hub but i didn’t find anything about this, there’s probably a solution to this but i can’t seem to find it.

Example : mousehover bug - Clipped with Medal.tv

My script :

local CollectionService = game:GetService("CollectionService")
local RS = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local LP = Players.LocalPlayer
local debounce = {}

local function MouseClickedBlock(blocks)
	local blockName = tostring(blocks.Name)
	if debounce[blockName] then
		return
	end
	debounce[blockName] = true

	local BlocksInfos = RS.Remotes.Main.C_C:InvokeServer(blockName)

	task.wait(0.1)

	debounce[blockName] = false
end

local function MouseHoverEnterBlock(blocks)
	local blockName = tostring(blocks.Name)
	if debounce[blockName] then
		return
	end
	debounce[blockName] = true

	local BlocksInfos = RS.Remotes.Main.C_I:InvokeServer(blockName)

	blocks.Highlight.Enabled = true

	local MouseInfos = LP.PlayerGui.GameUI.MouseInfos
	MouseInfos.Visible = true
	MouseInfos.BlockName.Text = blockName
	MouseInfos.BlockRarity.Text = "1 / " .. BlocksInfos[1].Rarity
	MouseInfos.BlockValue.Text = BlocksInfos[1].Value .. "$"
	MouseInfos.BlockName.BlockNameBG.Text = blockName
	MouseInfos.BlockRarity.BlockRarityBG.Text = "1 / " .. BlocksInfos[1].Rarity
	MouseInfos.BlockValue.BlockValueBG.Text = BlocksInfos[1].Value .. "$"
end

local function MouseHoverLeaveBlock(blocks)
	local blockName = tostring(blocks.Name)
	if not debounce[blockName] then
		return
	end
	debounce[blockName] = false

	blocks.Highlight.Enabled = false

	local MouseInfos = LP.PlayerGui.GameUI.MouseInfos
	MouseInfos.Visible = false
end

local function setupClickDetector(blocks)
	local BCD = blocks:FindFirstChildOfClass("ClickDetector")

	if BCD then
		BCD.MouseHoverEnter:Connect(function()
			MouseHoverEnterBlock(blocks)
		end)

		BCD.MouseHoverLeave:Connect(function()
			MouseHoverLeaveBlock(blocks)
		end)

		BCD.MouseClick:Connect(function()
			MouseClickedBlock(blocks)
		end)
	end
end

for _, blocks in pairs(CollectionService:GetTagged("BlockClick")) do
	setupClickDetector(blocks)
end

CollectionService:GetInstanceAddedSignal("BlockClick"):Connect(function(blocks)
	setupClickDetector(blocks)
end)

you might want to try Mouse.Target
