The Automatic "Slide in Out" Behaviour - can the slide be stopped midway somehow?

Question

The behavior library has a behavior called "Slide In Out"
within the animations -> automatic section. There's a command to
activate the slide by a message, but as I am going through the
coding in it to review it, I don't see a command to stop the slide
if it's running. Is there a way to do so? Go to the Frame doesn't
do it since it's not related to the playhead moving.

Answer 1

Replace the current prepareFrame() handler with this:
property pPaused
on prepareFrame me
if not pPaused then
mUpdate me
end if
end prepareFrame
on Pause(me)
pPaused = the milliseconds - pStart
end Pause
on Continue(me)
pStart = the milliseconds - pPaused
pPaused = FALSE
end Continue
You can now use...
sendSprite(<spriteNumber>, #Pause)
... and...
sendSprite(<spriteNumber>, #Continue)
... where you should replace <spriteNum> with the
number of the sprite that you are working with.
