hi Carlos,
true in the frame where I press the space bar for the first time, but also
at some other frames after the first one, when the space bar is pressed
yes, as Kassen already mentioned this is normal and comes from the
keyboard repeat.
I took a look into modules/scheme/input.ss to try to implement this behavior
as you said, but as I am new to fluxus I would first get familiar with its
sorry for bringing that solution up. it is probably too complex for this
problem. i thought you need callbacks on key presses.
source code. Thus, I ended up implementing all using (key-pressed-this-frame
" "):
clever solution. as i see you are detecting key release.
are you using fluxus from git? maybe we should add a (key-released)
function which could make this simpler.
something like this would be more general for now:
(define PLAY #f)
(define key-released
(let ([keys-down-last '()])
(lambda (key)
(let* ([keych (string-ref key 0)]
[released (and (member keych keys-down-last)
(not (member keych (keys-down))))])
(set! keys-down-last (keys-down))
released))))
(define (render)
(when (key-released " ")
(set! PLAY (not PLAY)))
(when PLAY
...))
(every-frame (render))
best,
gabor
