# from position 10 to 90

$position = 10


 servo(d1, $position)

 print("Position: $position")



 $position = $position + 10

 if ($position > 90)


Say("I'm Done counting!")

# Simple demonstration of variable usage
# All variables must be assigned before 
# being used in a function

say("I'll do some math for you")

$y = 5

$x = 5 + 3 + $y

servo(d1, $x)

say("X equals $x")

# This script will read the position of
# the servo on D1

$servo = GetServo(d1)

Say("Servo 1 is at position $servo")

I go on vacation and there are 3 big updates waiting for me! Awesome!



Is it possible to add ScriptStopWait as well?

I link to different scripts, starting and stopping many within Script Manager.

Sometimes scripts are not getting stopped and I have to currently add Sleep delays. Could you add ScriptStopWait to overcome this?




Lumpy, no there isn't - script stop will stop - the issue you are experiencing has been addressed in the thread you started regarding it.
