Title: Global settings
Post by: YellowBirdAZ on February 10, 2018, 10:54:29 AM

Is there a way to set a global variable on launch that can be referenced (and changed) from any layout or plug-in?

So whatever you set it to (say true or false) would stay the same no matter where it was referenced from (layout, plug-in, screensaver, etc.). And likewise the value could conceivably be changed from any of these places.

Might this be what the fe.nv table is for?

Yes. However, be careful that you don’t mess with other params and loose them. There’s no real guideline. I opted for fe.nv.layout_plugin_module <- {} to keep things working nicely between devs.

Check out how I am using it:

Thanks!

I copied yours. The only difference is I only need to store one boolean in there.

if (!fe.nv.rawin("jukebox")) fe.nv.rawset("jukebox", false);

In jukebox mode you get music from whatever era of games are displayed (80s, 90s, etc) and the audio for all videos is turned off (Vid.NoAudio).

In non-jukebox mode you get the opposite (no music, but audio for videos is re-enabled).

The Custom1 input toggles between the two modes.

With the NV variable I can have these settings persist even when the screensaver is active.
