"one shot" Lua in Virtual Device


JanJoh

Question

I have a virtual device which pretty much is just a few buttons, and labels.

Each button toggles a global var 1/0.

Each label just shows the value of a global var.

Now, since I have read a few posts which seem to indicate that the main loop may get stuck and/or simply behave erratically, i wonder if there is any way for me to avoid it.

I would like to fire off lua when the device is opened in the client to be able to update all labels. But it does not need to auto-refresh (since i can update the labels when a button is clicked).

But the only way i see to do this is to put the code to update labels in main loop?

"Best" practice is to put the update code in a separate button and then "hit" the button from main loop. This has been known to work for others, including me, instead of using the main loop straight up.

    Unfortunately that leads to an unnessecary button in the device. Which bugs me.

  • You could use a separate device for the looping to avoid that.

    Uhm.. okay.. so a VD can change properties of another VD? I actually did not know that. I just assume with all the sandboxing that... well you see what I mean

    I nice feature would be to be able to hide buttons and labels. That way you could do what you want but have them not to show up in the GUI's.

    Oh, I second that

    Anyway, i think i will do it a bit differently.

    The scene is a "trigger on motion breach" kind of thing. So, the first statement is pretty much a "if sesor value == 1 then..."

    I figured that if i put code outside that statement to update the labels, and then set the scene to run on HC2 startup i would get what i want. Lables would be initialized properly, and then the buttons would update on press. So, this way i should be able to avoid the main loop all together.
