Re: Hot Girls And Wild Horses! (Rev MX)
Hi Troy, Multi-player on-line gaming is a great test case for Rev, because gaming really pushes the systems. Bingo especially. Here you have a lot of people who need to be on the same page, and it's very time sensitive. The Bing-Go-Go game at http://www.palmspringsbingo.com/sgn for example is a high-speed version that plays a new game *every minute*. Under Flamethrower, we've often averaged a couple hundred people, with 4 cards each, playing with each other continuously. This goes on around the clock. For that game alone, there are 25 focused cgis, that work together and share memory. -They're also passing off data to another DB. We have G4s serving running the game, and an NT SQL db that the cgis hand the live game data feed off to. I've been very happy with the results of Flamethrower, but to ramp the games up to very large scale, we need to operate with sockets, and cross-platform servers, which Rev does, and that is why I'm here. Haven't built any websites with anything other than Flash for several years now. I'm very jazzed about the new possibilities enabled by MX. It's unfortunate that so many developers think of Flash as an animation tool first, and just use it for intros. Artists! Sheesh. That's *really* missing out on the available technology. To me, Flash is a cross-platform browser scripting language first. For those unaware, in MX, the language is very Javascript-like. AS is based on the ECMA-262 Javascript standard. Some differences are that AS does not support some browser specific objects such as document, window, or anchor, and does not completely support all of the predefined Javascript objects. It also doesn't support some constructs like switch, continue, try, catch throw. It doesn't support Unicode; it supports ISO 8859-1 and Shift-JIS character sets. At any rate, the above hasn't slowed us down at all in regard to building demanding web applications. Also, I'm not far enough into MX yet to know if any of the above has changed. It might have. AS does support some syntax constructs that are not permitted in Javascript, however. Also, AS performs cross-platform very well, which you can't say about Javascript, or Java. All IMHO, of course. Now, on-line gaming development may not be your bag, but the work done in it, I believe, is paving the way for other serious on-line community applications to come, especially in Education. That's a huge market for developers, and IMO has never been done really well in the past. would also be interested in the challenges such a solution has solved for you in the past To be honest, the most difficult ones in the past have been in the way the various browsers have handled TCP. There are lots of undocumented gotchas out there. The least of our problems have been with Flamethrower and Flash, although the earlier Flash required some real programming tricks to get AS to perform the way we needed it to. As far as I'm concerned, the last ball chain is Flash's purposely hobbled writing to local disks. If I could build a local Rev cgi engine that (browser) MX could communicate with as it does now with server cgis, I'd be a happy camper. The best new features of MX? Loading jpegs on the fly just like load movies, and the internal video. For us it means bye bye to Real, QT, and WMP. Plus the video experience is totally scriptable and interactive to the Flash presentation when it's embedded this way. The sorenson codec they're using is sweet indeed. For my company (so far) MX development and Rev development are independent of each other. You might want to reconsider that approach. There is a serious advantage to an author understanding both the Flash client side and Rev server side, and how they interact with each other. How far each can push each other, etc. This really speeds up development, and produces a much higher quality result. Anyway, the problem really isn't the available technology, especially now. It's in getting developers to think in terms of web/browser-based applications instead of desktop applications. There's a whole world of them out there waiting to be developed.

You actually have to append a space, not empty. There's one for me. LOL. I tried spaces on either end. They still compare as representing numbers. But that other example I found. That is a good place to concatenate empty. I think the problem is that when an alternate representation of a number is converted to a string, the string is not always a numeral of the number represented. A value in that case has sort of a split personality. dar ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Re: MOD function does not work! So be warned!
[I sent this message the first time from the wrong account. If it comes through twice, sorry--mdm] The MOD function works. The ROUND function might not. Decimal 0.1 when converted to binary is actually slightly greater than decimal 0.1. Set the numberFormat to something very precise and you will see that .1 is really 0.1555111512312578 When you keep adding increment eventually you reach a point where the sum of all those 5.5e-19ths (if I counted right) become significant to the MOD function. I think David Vaughan has said all this already but it is a very important point. But the round is NOT the way to go on mouseUp put 1 +.1 into aa put aa into line 1 of fld 1 set the numberFormat to \ 0.## put aa into line 2 of fld 1 put round(aa,1) into line 3 of fld 1 end mouseUp fld 1 is 1.1 1.1000888178419700125 1.0998667732370449812 I don't see it in MetaCard 2.2.3 (line 2 and 3 are the same in 2.2.3) but the results are the same as above in MC2.4.1. I think this might be a BUG. If you want to be testing as is in this example increments of tenths, I something like set the numberFormat to 0.# and add the line put loop into loop to your repeat clause. michael Ian Summerfield of [EMAIL PROTECTED] wrote the following on 3/28/02 9:53 PM The code I give here might look inefficient, the code comes from a large project, so there are reasons for doing it this way!
