So far this is what I have, but I want one where it just doesnt allow letters.
function CheckForNums(Box)
if Box:IsA("TextBox") then
TT = {}
for i=1, #Box.Text do
TT[#TT] = Box.Text
end
Box.Text = ""
for _,v in pairs(TT) do
if tonumber(v) ~= nil then
Box.Text = Box.Text..v
end
end
end
end
while wait() do CheckForNums(script.Parent) end
I'd like to know a better way as well~
local textBox = script.Parent:WaitForChild('TextBox')
local function checkstr(str)
local fullStr = ""
for i in string.gmatch(str, "%d") do -- Only checks for numbers
fullStr = fullStr..i
end
return fullStr
end
textBox.Changed:connect(function()
local filter = checkstr(textBox.Text)
textBox.Text = filter
end)
Or as Disillusions pointed out
local textBox = script.Parent:WaitForChild('TextBox')
textBox.Changed:connect(function(prop)
if prop == "Text" then
textBox.Text = string.gsub(textBox.Text,'%D+','')
end
end)
This works, however, it removes the starting text inside the textbox, anyway to fix that?
easier way: string.gsub(str,'%D+','')

Use a number value?
