Re: [Silly Question]Treating keys like buttons . . .
by Dean_Swan＠Mitel.COM 06 Jan '00

From: Dean Swan@MITEL on 01/06/2000 10:48 AM Andrew, I've discussed this with Andreas and John Maloney, because the same capability would be useful to use the hardware buttons on WinCE devices as substitutes for the mouse buttons. The short answer seems to be that Squeak doesn't currently support this, and support for this capability would be platform dependent. The other thing to note is that not all platforms support key up events at all. Another (obvious, imo) limitation is that since most keyboards are wired as a row/column matrix, keeping track of multiple keys that are pressed simultaneously can be problematic or impossible depending on the combination of keys. There is, of course, an exception to this: ALL MIDI keyboards can report key on (down) and key off (up) events for every key in any combination, and Squeak does have pretty good MIDI support (either the standard system, or Siren), so you *could*, in theory, write a (platform specific) keyboard driver that echos all key down and key up events from the host OS out a MIDI port, mapping them to MIDI note numbers (perhaps on some specific channel like 16) and connect a MIDI cable from that MIDI Out to another MIDI In to get the events back into Squeak. This whole keyboard to MIDI thing may sound a bit convoluted, but it would *NOT* require platform specific changes to Squeak, which may make it worth bothering with. -Dean Swan dean_swan(a)mitel.com "Andrew C. Greenberg" <werdna(a)gate.net> on 01/05/2000 11:39:44 PM Please respond to squeak(a)cs.uiuc.edu To: squeak(a)cs.uiuc.edu cc: (bcc: Dean Swan/Ogd/Mitel) Subject: [Silly Question]Treating keys like buttons . . . Please forgive me if there is a simple answer to the following question. I seem to be unable to find a straightforward way to accomplish in Squeak a "trick" I commonly used in my old video-game design years: exploiting the capacity to detect when a key has been released to treat keyboard keys much in the way we presently treat mouse-buttons. A common trait of modern computer games (and some real-time systems) is a perceived capacity to react seamlessly to commands as they are entered by a user. Particularly in many "first person" style games, and even old-style games like Wizardry, keys are used much in the same way as mouse buttons, to represent an on-off state for a particular feature. In "my old days," it was fairly common to de-facto or actually (depending upon the tech) spin off a process that would discern when certain keys had been pressed or released, and maintain a global state accordingly. For simpler game logic or tight and predictable main loops, this could also be accomplished synchronously. The game's main loop would then simply check the global state to discern whether a "key-button" is in the up-state or down-state. This approach greatly simplifies game logic in a "sur"real-time simulation of autonomous and user-controlled entities. A modern analog is the MacOS keyUp and keyDown event. I presume this is true of other modern windowing systems, with which I am somewhat less familiar. Squeak seems to model the keyboard as a buffer stream only, suppressing all key-up commands, so that there is no way, for example, to realistically discern the period of time during which a key has been released. Is there a facility for doing what I want to do inside of Squeak, either on a machine-specific or -independent fashion, or have we learned more "modern" ways to do these old-timer computer game tricks? Is this something we should be thinking about?

Hi, I've put the Mac PPC and Win 95/98/NT bundles up on the FTP site. I'll put the others up as the VMs and plugins are built.

Presentations in Squeak (Was: Where is the OOPSLA"99 Dan Ingalls video ?)
by Eric Scharff 06 Jan '00

06 Jan '00

I'm afraid I don't know anything about the video's availability, but I do have another question... :) This question is directed at folks who have done (active) presentations / demonstrations in Squeak. Of course, doing slide presentation type stuff isn't what Squeak is good for. Still, having primitive support for certain kinds of things (bulleted / outline lists, multiple screenfuls of information, etc.) would be quite helpful as a first step towards producing more active presentations. As a Smalltalk programmer but a Squeak (and especially Morphic) newbie, what would be the best way of producing presentation-like things with traditional elements but adding active / evolving content? What would be the best way of approaching something like a presentation? For now, this question would be directed for me (one who loves programming :) ) but eventually, this would also be the kind of things I would want my students to do. Any guidance would be greatly appreciated. Thanks! -Eric __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo! Messenger. http://im.yahoo.com

Bolot has promised Je77 and me the latest Comanche (with cookie support, XML RPC, and other niceties) by today (right, Bolot? :-), so it should be available ASAP. (Our semester begins tomorrow, so we're racing to get the latest versions of Comanche and ComSwiki up today.)

Does anyone have fixed size (proportional) font? *.sf2 would be great. I'm having trouble with text formatting considering that O's and W's take up more room than say i's and l's. Or is there another way? R. Shiflett <-- not a font wiz

I tried a couple times too. Best answer I got was to the effect of, "we are considering it, but we aren't sure we can afford the cost". I pointed out the obvious, and didn't hear back. Ho hum.

[Win32/WinCE] Squeak 2.7 Available
by Raab, Andreas 06 Jan '00

06 Jan '00

Folks, I've just finished updating everything for 2.7 - here we go: Windows NT/95/98 blablabla -------------------------- The whole bundle (e.g., binaries, image, changes, source): http://isgwww.cs.uni-magdeburg.de/~raab/squeak/Squeak.zip Binaries only: http://isgwww.cs.uni-magdeburg.de/~raab/squeak/SqueakExe.zip VM Sources (for all Win32 versions, including CE): http://isgwww.cs.uni-magdeburg.de/~raab/squeak/src/Squeak27Bld1Src.zip Windows CE ---------- MIPS (binaries only): http://isgwww.cs.uni-magdeburg.de/~raab/squeak/WindowsCE/MipsSqueak.zip SH3 (binaries only): http://isgwww.cs.uni-magdeburg.de/~raab/squeak/WindowsCE/Sh3Squeak.zip Notes ----- * Win95/NT should now handle FP errors accordingly. Those folks who had crashes entering PWM7 should try with the new VM. * WinCE should be quite a bit faster now (though probably draining more battery power ;-) since I've been turning off the 'reduce CPU usage' by default for WCE Enjoy, Andreas
