Good evening

Anybody can help me?

Shameless plug: Here is how to do it with SUIT. The important part is in the validate function, which uses string.gsub() to remove unwanted characters. You can do anything you like here.

Code: Select all

local suit = require 'suit'
local utf8 = require 'utf8'

local function validate(input)
  local len = utf8.len(input.text)

  -- allow only lowercase a-z (also no spaces, etc)
  input.text = input.text:gsub("[^a-z]", "")

  -- reset cursor to where it was before charater removal
  input.cursor = input.cursor - (len - utf8.len(input.text))
end

local input = {text = ""}
function love.update(dt)
  -- place textbox at (100,100) with with 200px and height 30px
  suit.Input(input, 100,100,200,30)
  validate(input)
end

function love.draw(dt)
  suit.draw()
end

function love.textinput(t)
  suit.textinput(t)
end

function love.keypressed(key)
  suit.keypressed(key)
end

-- if you want IME input, requires a font that can display the characters
function love.textedited(text, start, length)
  suit.textedited(text, start, length)
end

Just download the SUIT project (you can download the .zip file here https://suit.readthedocs.io/en/latest/i ... ml#suit-up
Extract it and then add all the .lua files to a folder in your proyect. For instance: vendor/suit and it contains button.lua, checkbox.lua, core.lua, etc.

Then, import it in your .lua file as

Code: Select all

suit = require 'vendor/suit'

and that's all
