A weird thing about .OnServerEvent:Wait

[Scryptings (Con Scrypt)]

Hello, I recently stumbled upon a weird thing using .OnServerEvent:Wait

to simplify, i was making a simple dialog box, but the text seems to be overlapping eachother, so i decided to add .OnServerEvent:Wait and waits for client to fire the remote, each time the dialog is finished, the client will fire it properly.

Incase you’re wondering of the code :

Server :

local remote = game.ReplicatedStorage:WaitForChild("Prompt")
remote.OnServerEvent:Connect(function()end)
game.Players.PlayerAdded:Connect(function(plr)
	task.wait(5)
	remote:FireClient(plr,"Hello! lol")
	
	task.wait(2)
	
	remote:FireClient(plr)
	remote.OnServerEvent:Wait()
	print("passed1")
	task.wait(2)
	remote:FireClient(plr,"The quick brown fox jumps over the lazy dog")
	remote.OnServerEvent:Wait()
	print("passed2")
	task.wait(2)
	remote:FireClient(plr,"yuo reading?")
end)

Client :

local remote = game:GetService("ReplicatedStorage"):WaitForChild("Prompt")

local frame = script.Parent.Parent
local text = script.Parent



local function convert(str)
	local result = ""
	for word in string.gmatch(str,"%S+") do
		result ..= '<font transparency="1">'..word..'</font> '
	end
	return result
end

local function setTransparency(str,word,value)
	for markup in string.gmatch(str,'<font transparency=.->.-</font>') do
		local findWord = markup:find(word)
		if findWord then
			local findTransparency : string = markup:match("<font transparency=.->"..word)
			local num = findTransparency:match("<font transparency=(.-)>")
			if findTransparency then
				str = str:gsub(findTransparency,findTransparency:gsub(num,'"'..value..'"'))
			end
			return str
		else
			continue
		end
	end
end

local ts = game:GetService("TweenService")

local tweenTime = .5

local info = TweenInfo.new(tweenTime)

local prompted = false

local framepos = UDim2.fromScale(0.5,0.048)

local toppos = UDim2.fromScale(0.5,-1)

remote.OnClientEvent:Connect(function(txt)
	if (prompted and not txt) or (txt == nil) then
		prompted = false
		ts:Create(frame,info,{Position = toppos}):Play()
		remote:FireServer()
	elseif txt then
		prompted = true
		ts:Create(frame,info,{Position = framepos}):Play()
		local converted = convert(txt)
		text.Text = converted
		for word in converted:gmatch("<font transparency=.->(.-)</font>") do
			local iteration = 25
			local delayBetweeniterations = .001
			for i = 1, iteration do
				text.Text = setTransparency(text.Text,word,1-(i/iteration))
				task.wait(delayBetweeniterations)
			end
			task.wait(.01) --delay per word
		end
		remote:FireServer()
		print("Fired")
	end
end)

Based on the video, as you can see when remove the connection to remote, it does not wait at all, but when adding a connection to a remote, it works as intended, was this documented in the remote event page?

If you’re asking why OnServerEvent:Wait() doesn’t work when you don’t call the remote event, it’s because OnServerEvent:Wait() only runs when OnServerEvent is called. it works same for the OnClientEvent:Wait() too.
