Hi Nicolas,

The good part about the easing functions is that they are agnostic towards
order of values. They always calculate the correct
value at the given elapsed time. A few minor changes to the original script
will make the circle disappear.
The most important change:
put aeEaseIn(0,360,pDuration,tElapsed,1) into tAngle
to
put aeEaseIn(360,0,pDuration,tElapsed,1) into tAngle
Values will decrease from 360 to 0 instead of increasing from 0 to 360. This
will in return first draw the full circle and then
make it disappear
I have revised the script a bit. Gave setArcangle a third parameter (pEffect).
This will allow you to make the circle appear or vanish as you wish with one
command call. Hope that helps,
Malte
on mouseUp
local tDuration
put 1800 into tDuration
setArcAngle the milliseconds,tDuration,"vanish"
end mouseUp
on setArcAngle pSecs,pDuration,pEffect
local tElapsed,tAngle
lock screen
put the millisecs - pSecs into tElapsed
switch pEffect
case "vanish"
put aeEaseIn(360,0,pDuration,tElapsed,1) into tAngle
break
case "appear"
put aeEaseIn(0,360,pDuration,tElapsed,1) into tAngle
break
case "bounceVanish"
put aeBounceEaseOut(360,0,pDuration,tElapsed) into tAngle
break
case "bounceAppear"
put aeBounceEaseOut(0,360,pDuration,tElapsed) into tAngle
break
end switch
set the arcAngle of grc "circle" to round(tAngle)
unlock screen
if pDuration>tElapsed then
if "setArcAngle" is not in the pendingmessages then
send "setArcAngle"&&pSecs,pDuration,pEffect to me in 40 millisecs
end if
else
if "vanish" is in pEffect then
set the arcAngle of grc "circle" to 0
else
set the arcAngle of grc "circle" to 360
end if
end if
end setArcAngle
