Text contains 1 but 1 is not a winning number so how do I fix it?
I want to detect the whole number from a given string (from TextBox.Text), and check if the string contains the specific number. Text contains 1 but 1 is not a winning number so how do I fix it?

local Text = "The winning numbers are Only: 12, 13."

if Text.find(1) then
    print("1 is a winning number")
end
#2

you’re printing that 1 is a winning number.

also, the text will always contain 1, since they both have 1 at the start.
12, 13.

you could probably do something like this

local num = math.random(1, 2) -- replace 2 with the highest number you want to be possible. if you only want it to go upto 13, put 13.

if num == 12 then
print("Win")
elseif num == 13 then
print("Win")
else
print("No win")
end

Sorry to say you cannot use math.random() because its not a string.

#4

You can use this: it should turn the random number into a string

local WinningNumber = {12,13}

local number = math.random(1,20)

if table.find(WinningNumber, number) then
	print("This is the number you got:"..tostring(number).. "You won!")
else
	print("This is the number you got:".. tostring(number) .."You lost!")
end

You can enter more winning numbers in the table

do you want to turn 1 to a string?

local Text = "The winning numbers are Only: 12, 13."

if Text.find(tostring(1)) then
    print("1 is a winning number")
end

I want to detect the whole number from a given string, and check if the whole number is equaled to a specific number.

Here’s a fix:

local Numbers = {12, 13}
local Text = "The winning numbers are Only: "
for i, number in pairs(Numbers) do
	if #Numbers == i then
		Text ..= number .. "."
	else
		Text ..= number .. ", "
	end
end
print(Text)
local Number = 13 --Use the value you want.
local index = table.find(Numbers, Number)
if index then
    print(Numbers(index) .. " is a winning number")
end

This works similarly to @PVP_Player2373902’s design.

I did a test before posting my code, you can concatenate numbers with strings perfectly.

#10

But my numbers are already stored as strings ://

#12

try this

local Text = "The winning numbers are Only: 12, 13."

if Text:match(tostring(1)) then
    print("1 is a winning number")
end
#13

It does not seem to work because it still prints it out ://

#14

The one I made stores numbers in a table then a number, creates the string based on the table, then finds if the number exists in the table. There is no need to store them as strings with my solution.

#15

its mostly because there is 1 in “12,13”.

#16

Lua’s string patterns really suck, no idea why they didn’t just implement the normal regex system everyone uses

#17 
local Text = "The winning number are only: 12, 13."

local numbers = Text:split(",") -- we split the commans

for index,numberwithtext in pairs(numbers) do -- we loop through the splitted points. But a problem is that it also has text so.
    local number,times = string.gsub(numberwithtext,"%D") -- we yeet the text out
    if number == 1 then -- see if number is equal to the number we want
        print("1 is a winning number!") -- do stuff.
    end
end
#18

Error: missing argument #3 to ‘gsub’ (string/function/table expected)

#19

ah wait I forgot lol here

local Text = "The winning number are only: 12, 13."

local numbers = Text:split(",") -- we split the commans

for index,numberwithtext in pairs(numbers) do -- we loop through the splitted points. But a problem is that it also has text so.
    local number,times = string.gsub(numberwithtext,"%D","") -- we yeet the text out
    if number == 1 then -- see if number is equal to the number we want
        print("1 is a winning number!") -- do stuff.
    end
end

Instead of using a single string to store your winning numbers, perhaps storing them inside of a table so you can open up your available options like so:

local winningNumbers = {12, 13, 23, 57, 1987349394}
local numberToCheck = 1

if table.find(winningNumbers, numberToCheck) then
	print(numberToCheck.." is a winning number!")
else
	print(numberToCheck.." is not a winning number.")
end

You can also do more complicated operations easier without needing to hardcode items so much. Like maybe randomly generating numbers between a certain range and putting them inside a table:

local winningNumbers = {12, 13, 23, 57, 1987349394}
local numberToCheck = 1

if table.find(winningNumbers, numberToCheck) then
	print(numberToCheck.." is a winning number!")
else
	print(numberToCheck.." is not a winning number.")
end

--Create 3 randomly generated numbers between 100 and 10000 and store them inside winningNumbers
for i = 1, 3 do
	table.insert(winningNumbers, Random.new():NextInteger(100, 10000))
end
print(winningNumbers) -->randomly drawn numbers are added

Or figuring out if the numbers are odd or even:

local winningNumbers = {12, 13, 23, 57, 1987349394}
local numberToCheck = 1

if table.find(winningNumbers, numberToCheck) then
	print(numberToCheck.." is a winning number!")
else
	print(numberToCheck.." is not a winning number.")
end

--Create 3 randomly generated numbers between 100 and 10000 and store them inside winningNumbers
for i = 1, 3 do
	table.insert(winningNumbers, Random.new():NextInteger(100, 10000))
end
print(winningNumbers) -->randomly drawn numbers are added

local totalEven, totalOdd = 0, 0
for i, winningNumber in pairs(winningNumbers) do
	if winningNumber%2 == 0 then
		totalEven += 1
	else
		totalOdd += 1
	end
end

print(totalEven, totalOdd) --> prints the total even and odd numbers
#21

What if I change the number we want to check to 12? It does not print out although it is a winning number.

local Text = "The winning number are only: 12, 13."

local numbers = Text:split(",") -- we split the commans

for index,numberwithtext in pairs(numbers) do -- we loop through the splitted points. But a problem is that it also has text so.
	local number,times = string.gsub(numberwithtext,"%D","") -- we yeet the text out
	
	if number == 1 then -- see if number is equal to the number we want
		print("1 is a winning number!") -- This should not be printed out
	end
	
	if number == 12 then -- see if number is equal to the number we want
		print("12 is a winning number!") -- This should be printed out, but it does not print
	end
	
end
