  • 1.  Visual Logic node

    Posted 07-02-2021 05:59

    I was playing around with Visual Logic to try various ways to reset a timer after being used.
    While doing so i noticed the node Scene - IsOnline, which gives a boolean as result.

    I figured this node could be usefull to reset a timer as soon as the scene goes offline.
    But as far as i'm aware, Visual Logic does only run when a scene is online...which makes this node kind of strange...

    What does this node do? How can i put it to use?


    Thnx!

    The most common use I have for it is to play none default scene directors. 

    IsOnline -> Scene Director Play

    Hmmm, i don't think i have encountered any situation where this would be needed, then again, my knowledge in Xpression only goes to a certain level..

    Basically isOnline distinguishes between being live or preview/not online at all. If it's only visible in preview, isOnline is false. If it's actually online, it's true (obviously).

    Like i said, as far as i'm aware, Visual Logic only runs when a scene is online, so when a scene is in preview, the scene is not online and Visual Logic would not run at all. Therefor the node would not be called upon and give no output, no online of offline boolean.

    Or am i wrong here and does Visual Logic run even when the scene is not online?

    Visual Logic runs when a scene is rendered, whether online or just in preview.
