How to make a GUI fade in/out when a player is touching a certain part?

Could you mark my post as the solution?

So I would highly advise against using the server-side to tween UI. I would recommend using the client.

Here is a client script, you will need to tweak it to your liking but it will work as I have tested it while creating it.

--Services
local players = game:GetService("Players")
local tweenService = game:GetService("TweenService")

--Constants
local player = players.LocalPlayer
local playerGui = player:WaitForChild("PlayerGui")
local screenGui = Instance.new("ScreenGui", playerGui)
local frame = Instance.new("Frame", screenGui)
frame.BackgroundColor3 = Color3.new(1, 1, 1)
frame.Size = UDim2.new(0.5, 0, 0.5, 0)
frame.Position = UDim2.new(0.25, 0, 0.25, 0)
frame.BackgroundTransparency = 1

--Variables
local part = workspace:WaitForChild("Part", 86400)
local debounce = false
local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, 0, false, 0)

--Functions
local function Action(type)
	local goals = {}
	if type == "FadeIn" then
		goals.BackgroundTransparency = 0
	elseif type == "FadeOut" then
		goals.BackgroundTransparency = 1
	end

	local tween = tweenService:Create(frame, tweenInfo, goals)
	tween:Play()
end

local function onTouchStart(hit)
	if debounce then return end
	if hit.Parent:FindFirstChild("Humanoid") then
		debounce = true
		Action("FadeIn")
	end
end

local function onTouchEnd()
	if not debounce then return end
	debounce = false
	Action("FadeOut")
end

part.Touched:Connect(onTouchStart)

--
runService.RenderStepped:Connect(function()
	if debounce then
		local touching = false
		for _, obj in ipairs(part:GetTouchingParts()) do
			if obj.Parent:FindFirstChild("Humanoid") then
				touching = true
				break
			end
		end
		if not touching then
			onTouchEnd()
		end
	end
end)

Let me know how this one works for you. Obviously I have made it very plain so as I said before, please tweak it to your liking.

Edit: Forgive my usage of a while task.wait() loop. Use RunService, please.

Oh! Okay well do not use touched events. They overall suck. Here though!

local CS = game:GetService("CollectionService")
local RS = game:GetService("RunService")

local overlapparam = -- overlapparams to filter out anything that you dont want

RS.RenderStepped:Connect(function()
    for i,v in pairs(CS:GetTagged("DeathPart")) do
        local touchingparts = workspace:GetTouchingParts(v,overlapparam)
        for _,v2 in pairs(touchingparts) do
            local h = v2.Parent:FindFirstChild("Humanoid") or v2.Parent.Parent:FindFirstChild("Humanoid")
            if h then
                -- make gui die
            end
        end
    end
end)

There may be bugs because it is not tested and I wrote this in devforum so yea.

Your use of RenderStepped is what I should have done with my reply, lol. I’ll quickly make an edit.

[AnomalousRobot (Sol)]

Alrighty, just give me a second to test and review everyone’s answers! I appreciate y’all’s time and help.

We already went over that, we used tween service on the client

[Velkaryn (Velk)]

This script doesn’t require a ModuleScript or a Remote Event, which is why I felt the need to post it.

[pf_z1]

When did we mention Module scripts? A remote event is much more understandable. it can be fired as soon as the player touches the part instead of having a RenderStepped function.

[Velkaryn (Velk)]

I used that approach as an example to demonstrate how function variables can be passed, creating what resembles a pseudo-service. In programming, the goal is often to achieve outcomes using as few lines of code as possible. Therefore, employing a remote event for detecting block touches is ultimately unnecessary when this can be efficiently handled on the client side, eliminating the need for server involvement.

Pf_sz1’s script does spawn the GUI but unfortunately doesn’t make it fade out once you’re no longer touching the block. Xurko, yours does exactly what I need! Haven’t tested Night’s yet since it appears to be a bit incomplete, I imagine either they forgot to add stuff or I need to replace some of the bits with my own code. Either way, I thank you all for helping me with this!! Now all I gotta do is transition the code to work with the tag system so I don’t have to copy and paste the code in every single part I want to have this effect.

I also took videos so people can see how your codes work, just in case it might be helpful for them.

Could you please mark my post as the solution if you feel your request has been fulfilled?

[AnomalousRobot (Sol)]

I believe I have, let me know if I’m wrong.

[Velkaryn (Velk)]

That was my bad, I needed to refresh the page, thank you.

Hey! Stealing my idea!! >:(
