Detect if capslock is toggled on ?

[KayleMaster]

Title says it all.
My code is in love.keypressed(key):

Code: Select all

if inputObj ~= nil then
   		if isLetter(key)==1 or isDigit(key)==1 then
   			if (love.keyboard.isDown("lshift") or love.keyboard.isDown("rshift") or key=="capslock") and #(inputObj.input_string)<24 then  				
   				inputObj.input_string = inputObj.input_string ..  numpadCheck( toUpper(key))
   			else
   				if #(inputObj.input_string)<24 then inputObj.input_string = inputObj.input_string ..  numpadCheck(key) end
   			end
   		elseif key == "backspace" or key == "delete" then
        	inputObj.input_string = string.sub(inputObj.input_string, 1, #(inputObj.input_string)-1)
   		end
    end

if key == "capslock" doesn't work, didn't expect it to, but worth a shot I guess. It says that Caps-on is a key-press, what does that mean? How do I check it?

Caps mode is OS-dependant, plus there are a few more text modes besides caps. The point is, you shouldn't care, and just take the input as it is. Then, after you're finished, you can do some text processing.

But the input has to be case-sensitive and I don't want to remove this functionality which is pretty much built in Windows from the user.
If I have to, I will check on which OS the user is (I'm planning a release for Windows and Linux only for now).

It sounds like you want to be using love.textinput instead. That automatically deals with caps lock, keyboard layouts, and even multi-key input sequences.

I don't want any special symbols in my string so I just wrote my own that accepts A-Z, a-z, 0-9.
How would I handle that with textinput?

The love.textinput function has a variable with the character in it. You could check that

Code: Select all

function love.textinput(t)
	if t == "a" then
		
	end
end

You accept all text input and then do string match with a pattern that only allows those characters:

Code: Select all

local output = input:gsub ( '[^A-Za-z0-9]', '' )

You can also do this on per-character basis, if you accept one character at a time. Just make sure to make some indication that character was not accepted.

Or you can filter out non alphanumeric when they type.

Code: Select all

function love.textinput(t)
	if t:match("%w") then
           --"It's alphanumeric only"
        end
end

Oh nice, didn't know about pattern matching yet.
Is the parameter of textinput a string, a key, or something else?

It's the UTF-8 encoded character that was pressed on the keyboard.
