Letters being detected as dots

[TurkishGamer546 (NoPicture)]

Hello people, I was writing a code to make letters appear one by one in a dialogue. So that when a symbol (e.g.: comma, dot, semicolon, etc.) comes up, it would stop for a selected amount of time. I made a table for those symbols, but for some reason, when I run it it detects every letter as a dot and pauses longer than the expected amount. I can’t understand why it detects every letter as a dot, but when I remove the dot from symbols table it behaves normally.

Heres the script:

local SymbolsTable = {",", "!", "?", " ", "."}
local function letterAppear(object, text)
	local detectedSymbol = nil
	
	for i = 1, string.len(text) do
		
		object.MaxVisibleGraphemes = i
		for _, symbol in pairs(SymbolsTable) do
			if string.sub(text, i, i):match(symbol) then
				print("Detected letter: "..string.sub(text, i, i))
				print("Detected symbol/space: "..symbol)
				detectedSymbol = symbol
			end
		end
		
		if detectedSymbol == "," then
			task.wait(0.2)
		elseif detectedSymbol == "." or detectedSymbol == "!" or detectedSymbol == "?" then
			task.wait(0.5)
		elseif detectedSymbol == " " then
			task.wait()
		elseif detectedSymbol == nil then
			task.wait(0.02)
		end
		detectedSymbol = nil
	end
end

letterAppear(script.Parent.Dialogue, script.Parent.Dialogue.Text)

When dot is added to the symbols table, the output shows this:

When it’s removed:

Is this a bug in the engine, or have I written something wrong in the code that I missed?

Why I cant find point in string

The period character is a magic character in string pattern, it just matches anything. Lucky for you, string.find has an optional last parameter that determines if string.find should use string patterns for the second argument. The argument before it is where to start finding, so you’ll need to provide that first. This leaves you with string.find(tostring(a), ".", 1, true), or if you want, you can escape the period with a percent sign. Which would leave you with string.find(tostring(a), "%.")

Try doing “%.”
