Highlight Every Time When Attribute Set to True

[TheAeriate (Aeriate)]

So, I want to make when attribute is set to true, I want to create a highlight that the whole server can see it.

However, I want to use TweenService so it looks better. But, I feel like it too slow when you change the attribute fast. I only want to create highlight when IFrame is true, however, when I try destroy it when it false. It also shows the following:

I want to use it globally but roblox appear to be dumb:

How can I solve this?

The following script runs when attribute changes:

local replicatedStorage = game:GetService("ReplicatedStorage")
local tweenService = game:GetService("TweenService")

local remote = replicatedStorage.Remotes:WaitForChild("AttributeChanged")

remote.OnServerEvent:Connect(function(player, character)
	if character:GetAttribute("IFrame") == true then
		highlight = Instance.new("Highlight", character)

		highlight.Name = "IFrameHighlight"

		highlight.DepthMode = Enum.HighlightDepthMode.Occluded

		highlight.FillColor = Color3.fromRGB(255, 255, 255)
		highlight.OutlineColor = Color3.fromRGB(255, 255, 255)

		highlight.FillTransparency = 1
		highlight.OutlineTransparency = 1
		
		tweenService:Create(highlight, TweenInfo.new(1), {FillTransparency = 0.75}):Play()
		tweenService:Create(highlight, TweenInfo.new(1), {OutlineTransparency = 0}):Play()
	elseif character:GetAttribute("IFrame") == false and highlight then
		tweenService:Create(highlight, TweenInfo.new(1), {FillTransparency = 1}):Play()
		tweenService:Create(highlight, TweenInfo.new(1), {OutlineTransparency = 1}):Play()
		task.wait(1)
		highlight:Destroy()
	end
end)

you have to use the _G. prefix when setting, calling, and changing global variables

What is _G and for what i can use it?

You can access variables from different server side scripts. If you have this in one script _G.player = "player" and this in another print(_G.player) it will print “player”

What for all scripts, not just the script.

[Bikereh (green_lady)]

every script that uses the variable has to put the prefix

Don’t think it helping

[Bikereh (green_lady)]

you have to use the prefix for every single time you reference the variable. all “highlight” with the lines under them, you have to put _G. before each one. not only one time in the whole script
