Now to explain what's going on with our program here. First, let me just showcase the main routine, once all the library stuff is out of the way:
Code: (Select All)Screen _NewImage(800, 600, 32)
Init_KeyCodes "US", 0.1 'language and repeat rate
Do
k = KeyHit: k1 = _KeyHit
If k Then
Print k;
If k > 0 And k < 256 Then Print Chr$(k), Else Print ,
Print k1;
If k1 > 0 And k1 < 256 Then Print Chr$(k1) Else Print
End If
_Limit 30
Loop
So what's different here, than with the old Keyboard Library?
First, we've swapped over to running everything on an ON TIMER loop, where we check and update our keyboard states 100 times a second. This allows us to continue to monitor the keystates even when we insert a pause into our program (think _DELAY 3 or SLEEP 3, though it'd need to be a routine which doesn't lock up execution of timers), and is now generating a keyboard buffer like we're used to seeing with _KEYHIT and INKEY$
Now, why would anyone ever be interested in swapping over to this KeyHit method, instead of just using the simple one we already have?
1) It's customizable. You can configure this to work with *ANY* style keyboard that you might have. Currently, it offers support for "US", "DE", "WE", and "IT" keyboards. (US, German, Western Europe, and Italian, if I remember all those abbreviations right.) Press that key for accented "A" on your keyboard, have that accented "A" pop up on the screen!
2) It reads and responds to keys that _KEYHIT, unfortunately does not. Try the CTRL + TAB combo with the demo and you'll see what I'm talking about fairly easily.
3) It's got a larger keyboard buffer -- 30 keypresses can be stored for future interactions, whereas we normally only have about 8 with _KEYHIT.
Now, I know you guys are all going, "WOW! SOUNDS AWESOME!!"... but there's one thing to keep in mind...
This is a WINDOWS ONLY library. I'm not a Linux/Mac programmer by nature, so I have no idea how the heck to read individual keystates on those OSes, so there's no way I'll be making this a cross-platform library anytime soon.
And with that said, let's talk about the actual little demo here and what you can expect if/when you run it.
First, let me just preface by saying this demo does nothing but print some key codes to the screen for you. (And maybe a few text characters, depending on what keys you hit.)
Run it, hit "A", and you'll notice that both KeyHit and _KEYHIT return the same value for your keypress -- 97 for down, -97 for up.
Hold that A-key for a few seconds, and you might notice something a little odd to you at first. You might see reports of 97 for KeyHit, but 0 for _KEYHIT... Don't be alarmed!! That's just a difference in the repeat rates between the two commands. I've currently got KeyHit configured to repeat keystrokes every 0.1 second (10 times per second). Your OS might have a different repeat rate than that. You can ignore those 0's that might appear on either side of the screen, in this instance.
Now, as I mentioned, try out some combo keys. Hold down CTRL and press TAB... Keyhit will report CTRL going down, and then it will report "9", "9", "9" for the TAB key being down. _KEYHIT, on the other hand, will *ALWAYS* just report "0", "0", "0", ... as it simply doesn't read that key combination!!
Even odder, when you release the TAB key, Keyhit will properly report "-9" for a Tab-UP event. _KEYHIT, on the other hand, reports -105 to us -- which is the code for an "I-key"-UP event!!
_KEYHIT thinks you never pressed any key down, but you let the "I" key up when you were finished holding down the key that never got pressed!!
As far as I can tell, everything here is working as it should now. If anyone has non-US keyboards and wants to give this a test run, just be certain to change the Init_Keyboard language code to whatever suits your keyboard, and then be kind enough to tell me what happens when you try and use it.
Linux/Mac folks can try to use it too. (For you, it should just swap out to a plain old _KEYHIT call -- SORRY!!) If you get some sort of error messages, or it behaves weirder than you'd expect with _KEYHIT, kindly let me know what the heck it might be doing for you. This isn't really supposed to do anything except for Windows-users... If it's not playing nice with other OSes, then something somewhere got wonkered out when I swapped over to putting it all on a timed routine, and I'll need to try and sort out what the heck that was.
It's much clearer now. Thanks.
Will the _keyhit command be updated, and will this mean another download of the whole of PE?
