Hi Nicolas,
what you would need to do to make it accurate on all machines is calculate the
value for the arcangle as it *should* be at the current time stamp.
that way it might look a bit jerky on slower machines, though I doubt that
would be noticeable. I am afraid I´ll need to blow my own horn here, so
*toot* *toot* You can do this with a timer using AEs easing functions.
The following script will always last 1800 millisecs (+- 40 millisecs, but
those are neglectible)
on mouseUp
local tDuration
put 1800 into tDuration
setArcAngle the milliseconds,tDuration
end mouseUp
on setArcAngle pSecs,pDuration
local tElapsed,tAngle
lock screen
put the millisecs - pSecs into tElapsed
put aeEaseIn(0,360,pDuration,tElapsed,1) into tAngle
set the arcAngle of grc "circle" to round(tAngle)
unlock screen
if tAngle<360 then
if "setArcAngle" is not in the pendingmessages then
send "setArcAngle"&&pSecs,pDuration to me in 40 millisecs
end if
else
set the arcAngle of grc "circle" to 360
end if
end setArcAngle
All the best,
