Oops, that para in the animate block makes it a bit slow sometimes, get rid of that (was just for some troubleshooting). I'm talking about the 8th line in the code.
Subject: RE: keydown? From: [email protected] Date: Sun, 5 Jul 2009 17:06:38 +0000 To: [email protected] I've cooked up a hack that pretty much works. It's implemented in terms of keypress events, relying on the fact that when you hold a key down, keypress events are sent every 0.1s or so (at most), except the keypress after the initial event/press, which takes 0.5 seconds to be sent (these figures are on my machine anyways, for a barebones shoes app, you can adjust values according to yours). The code takes account of the pause after the initial event, with the disadvantage being that if you just press the button, it will assume it has been held for a full 0.505 seconds. Which may be totally acceptable for a lot of use cases. The other choice in this hack would be to wait for the rapid events, but that would make it feel very sluggish. Also, I'm sure this could be abstracted out to look more like what you wanted, a function where you passed in the key, but I leave that as an exercise to someone who needs it. Here's the code: Shoes.app do @info = para '' @s = stack @t = Time.now animate( 10 ) do if up_pressed? @info.replace "You pressed UP!!!" @s.append { para "up - ", Time.now.to_f%100, " - ", @t.to_f%100 } # Check these paras to see the reason for problems else @info.replace "C'mon, you know you wanna press the up button, just do it already" end end keypress do |key| if key.inspect == ':up' and Time.now - @t < 0.15 # Continued press, where keypress events are fired off every ~0.1s @t = Time.now elsif key.inspect == ':up' and Time.now - @t >= 0.15 # Initial press, which will followed by a second keypress event after ~0.5s pause, if held down, hence the delay @t = Time.now + 0.505 end end def up_pressed? # If the following statement is true, the up button is probably being held down, since the last even fired less than 0.15s ago Time.now - @t < 0.15 end end And this code should provide the timing of keypress events, in case they're different for your hardware (also the events are slower if lots of things are going on I guess, so you'd have to adjust the 0.15 values): Shoes.app do @t = Time.now keypress do |key| para "\n" if Time.now - @t > 0.15 para Time.now - @t @t = Time.now end end > Subject: keydown? > From: [email protected] > To: [email protected] > Date: Sat, 4 Jul 2009 10:16:27 -0700 > > I want to be able to do this: > > kd = false > animate 24 do > kd = keydown?(:up) > end > > Can we have keydown in some form or another? > > -- > ~devyn Insert movie times and more without leaving Hotmail®.
