GetKeyboardBuffer - How do I detect the enter key?

RodrigoDavy

I tried it like like this:

k = getKeyboardBuffer()

if(k == "\n") then
    print("Bingo")
endif

It doesn't work. I have no idea how to detect enter. If anybody could help, I'd be grateful :)

I found a way to do it

showKeyboard()
k = getKeyboardBuffer()

if(chrVal(k) == 10) then
    print("Bingo")
endif

Not super clean, but it works!

While you might reasonably expect "\n" to work, using chrVal is probably the correct way to do it since that is resolving the keystroke down to a single value instead of trying to compare against two values. ( '\' + 'n')

Gothon

"\n" is the escape code for a new line character, but I noticed in a program of mine that it generated an extra character of white space. It seems it actually generates a linefeed and a space character chr(32) + chr(10), so I am not surprised that if k == "\n" then ... doesn't work for reading the keystroke.
