Re: Animated Gifs on Other Cards

[hh]

TMHO it is much better to animate gifs by an own handler (send in
'regular' time intervals, for example every next full second).
Only by that you have full control on the animation speed on different
hardware. I have a lot of gifs whose speed is set to "fastest", not this
perfect on fast machines, only fine old PowerPCs.

And by setting ONE "check" (variable) you can start/stop
the animation:
= stop at once/ after finishing the loop/ after a certain time amount
= don't stop but pause only
= stop forever after a certain number of repeats
= pause for a certain amount of time
= pause while the suspended
= stopping if the cycle becomes too slow
etc ...
As usual this may all be done by one handler for each gif or
by ONE handler up in the message hierarchy for several gifs.

Good input… off screen or on top card of open window behind the top stack: GIF 
is still running…

Given that we might be instantiating the appearance of these GIFs (icons of 
buttons) "here and there and everywhere" via some low level back script or lib 
that was brought into the msg path with start using… it makes sense then to 
hide it as a "best practice" … with a generalized behavior… this would avert 
the need for additional "sensor code" to be have to check if the window was 
open but behind etc.  

I haven't tried it recently, but I once (years ago) had a number of animated 
GIFs on my desktop (mac)… and the Finder ran slow as molasses.  Put them all 
into a folder, Finder became responsive again.

This got me to thinking the other day, if they slow down LC performance when 
running.

The other term use case beside brief appearance of indicators that come and go, 
 would be even more intensive: in this case we know what is happening, they are 
all there, running on top: set 4-8 animated GIF figures to start moving around 
on the screen, with some voice over story line… will this "die" on a cheap 
Android phone? TBD

Of course we can benchmark this now that we know when the GIF still runs or not.

Makes sense. There really is no "off screen" to the modern computer.

Yet another option.

One may use for the 'it-pauses-until-coming-back'-test a gif that
counts in seconds from 0 up to 100:

giphy.com/gifs/TCJTqRAxRbhGU   (repeatCount=-1)

Note. If you go to a different window (of LC or not), leaving the
running gif on the top card of its window, then the gif keeps going
on, whether hidden by another window or not.

Put an animated GIF on a card, and this in the stack script:

on idle
   put the currentFrame of img 1 of cd 1
end idle

Then go to another card.

Here, a quick test confirms Jacque's hunch; the Message Box only updates
when I'm on the card with the GIF.

I'm not sure if that would work: as if you left a card while a GIF was 
in mid-cycle it might be paused at that frame until you returned to that 
card.

Animated Gifs on Other Cards

[Sannyasin Brahmanathaswami]

if we import an animated gif into a card called "image-resources" which might 
be e.g. card 3. with repeat set to -1… i.e it is running continuously…

When are on Card 1… is that GIF still running and taking up CPU cycles even 
though it is effectively "hidden" by virtue of being on Card 3?

OR

is best practice to always stop, start and stop them programmatically so that, 
when not actually shown, they are not repeating?

Use case would be to use an animated give as the icon for a button… if you set 
the icon ID of  a button on cd 1 that is an animated running GIF stored on card 
3  it works, but I'm concerned about any performance degradation that these 
might have if left repeating "behind the scenes"

perhaps there are none, if not, that would keep life simple and you don't have 
to commands to stop and start the GIF every time you want to show it.
