love.keypressed Stops Working After First Press

[Kookerus]

I'm trying to make a program wher the user just types in a box, and if backspace is pressed, the last character is deleted. I have the code working, but the second time bacekspace is pressed, it won't delete the last character.

Code: Select all

function love.load()
	intro = "Type away! -- \n"
	text = ""
	numTimes = 0
end

function love.textinput(t)
	text = text .. t
	numTimes = numTimes + 1
end

function love.keypressed(key)
    if key == "backspace" then
        text = string.sub(text, 1, numTimes - 1)
    end
end

function love.draw()
	love.graphics.printf(text, 0, 0, love.graphics.getWidth())
end

Can anyone help me?

Never mind. I realized I forgot to decrease the "numTimes" variable. Changed it and it worked like a charm!

Okey just so that you can learn some things:
you could use something like

Code: Select all

text = text:sub(1, numTimes - 1)

notice that text:sub is the same as string.sub(text...)
also you can do

Code: Select all

text = text:sub(1, text:len()- 1)

text length should return the number of characters in text
or instead use something like

Code: Select all

text = text:sub(1,-2)

Since negative numbers count from the last character + 1 (because it is inclusive)
Have fun with lua!!

Thank you so much! I've never used lua before, and it's quite a bit different than python

Well... I have never used python (I used it once but just a little) so I will call you when I need to

Sounds like a plan!
