Monitor changes inside Scriptfx - the correct method? (broadcasters listeners)

What am I misunderstanding?
I don't think I am doing it right lol.

@griffinboy Actually that looks exactly what I have been doing in my test project. What's the problem here? Does it not compile or does it not work?
Remember you have to initialize and create the global cable with the exact ID you used when creating this code snippet BEFORE you load the effect (or use Recompile all scripts to reinitialize the connections afterwards).
-
The global cable doesn't update when you move the knob.
Maybe my Ui code is at fault?
Content.makeFrontInterface(300, 300); const var rm = Engine.getGlobalRoutingManager(); // Create the global cable const var mc = rm.getCable("GC1"); // Add another panel. This will just display a circle with the alpha value modulated const var P2 = Content.addPanel("P2", 110, 50); // Now instead of the timer we use the asynchronous UI callback provided by the cable. mc.registerCallback(function(value) { // Write the value into the data object and repaint the panel P2.data.val = value; P2.repaint(); }, AsyncNotification); P2.setPaintRoutine(function(g) { g.fillAll(0x22FFFFFF); g.setColour(Colours.withAlpha(Colours.white, this.data.val)); // Rawdogging the area like a pro... g.fillEllipse([25, 0, 50, 50]); });Yeah, recompile all scripts didn't work, and also there is a glitch that has developed where when you click to add a new scriptnode to the tree, you cannot close the dialogue box.

Bump

Anything I can do to help debug it?
*edit, I saw that a while ago you uploaded a new build, I'll install it in the morning and see if maybe I just caught an in-between build.

@griffinboy I looked into yesterday because it worked for me but then I realized that we're talking about different things. I was checking the Hardcoded FX and you are probably loading the node in a network (because there it doesn't work yet).
I tried to fix it but there is one nasty persistent crash when unloading the nodes that connect to a cable that I still have to fix. In the meantime you can check the procedure with the hardcoded FX module, there it should work.
-
Alright, please check it again, now it should work.
-
I'll check it! Thanks for the update.
-
It works! Thank you!
I'll do a video on this soon in my scriptnode c++ series. I've been remaking the first few videos to make more sense and go into better depth. -
