Filtering for specific characters isn't working

Fixed the issue, I had to rewrite pretty much the whole function.

local function clamp(x:number,min:number,max:number)
	if x < min then
		return min
	elseif x > max then
		return max
	end
	return x
end

local function textFilter(text:string, filter:number, min:number, max:number)
	if filter == 1 then --only numbers
		local filteredText = ""
		local decimalCount = 0
		
		for i = 1, #text do
			local char = text:sub(i, i)
			print(char)
			if char:match("%d") then
				filteredText = filteredText .. char
			elseif char == '.' then
				if decimalCount == 0 then
					filteredText = filteredText .. char
					decimalCount += 1
				end
			end
		end
		
		if decimalCount == 1 then
			if min ~= nil and max ~= nil then
				local numberToClamp = tonumber(filteredText:split(".")[1])
				if numberToClamp == nil or numberToClamp == "" then numberToClamp = 0 end
				local newNumber = clamp(numberToClamp, min, max)
				if newNumber == max or newNumber == min then 
					text = newNumber
				else
					text = filteredText
				end
			end
		else
			local number = tonumber(filteredText)
			if number then
				if min ~= nil and max ~= nil then
					text = clamp(number, min, max)
				end

				print(text)
			else
				text = ""
			end
		end
	end
end

Do with the script what you will, I don’t really have time to explain it :sweat_smile:
