Re: here is the CLOCKFACE script...coded in 3 MINUTES...17 LINES of CODE
I considered this option and went the other way for a couple reasons. It seemed more natural to leave it in one handler. It takes more lines of code to split the handlers up. I wonder what the overhead is to have three messages pending as opposed to one. That said, I think this is the way to go. It solves the display-isn't- right-for-up-to-two-minutes problem, and the implementation is about as clean as can be. I think we may finally be close to the optimum solution. gc On Jun 8, 2005, at 9:35 AM, Dennis Brown wrote: Geoff, Your new idea gave me an idea.

Geoff, It does have a certain elegance to it --and it preserves the subject header of 17 LINES of CODE ;-) The 3 MINUTES has grown just a tad to get it to it's current evolution. I just don't like the long math line to get the hours straight -- could there be a simpler way? Now all we need is a deep bitmask clockface to make it pretty. Perhaps a chime or coo-coo and an alarm setting to make it a fully functional simulation. These would be easy using the same delayed handler idea.

Nine out of ten seconds, the only thing this routine is going to do other than set the second hand is check whether T[3] mod 10 is 0.

I like that split concept. I am always setting itemdelimiter to odd

caught.

local sHourAngle -- the angle for the hour hand
local sMinuteAngle -- the angle for the minute hand
on setTime
put word 1 of the long time into T
put T the long seconds into fld time

I originally went with polygon graphics, which put me at about twenty lines of code by your way of counting (including on and end statements). Switching to oval graphics I got it down to 11 lines, which sweep both the hour and minute hands. But the second hand is jumpy.

If that happens _and_ the time spent executing the send...in is 0, _and_ the send...in trigger happens _exactly_ on schedule, it would still be he next second, and do the right thing. Underneath, the queued message is associated with a time. In my tests, that time is just past the whole second. Perhaps the code that checks the pending messages waits to see if the current time is greater than or equal the time associated with the message. So, even if the clock has a low resolution, it has to pass the target time. Also, the time value used in display is probably based on the same clock, so all is well.

That is a good point. I tested it out, and the useless set angle results in about 70ms of wasted time every second (7% CPU). I am surprised it is so high.

Darn, forgot one more thing. Instead of setting the itemDelimiter, using the split command allows a cleaner T[1] syntax instead of item 1 of T. It is probably a bit faster as well.
