How to use Global Cables in fx plugin

[JulesV]

I'm gonna use Global Cables for the first time in my fx project.

There are posts on the forum but does anyone have any suggestions on how I can get started?

@JulesV You can start with this:

HISE | Examples | Scriptnode Snippets

Examples in the category Scriptnode

(docs.hise.audio)

@resonant Thanks!

Is it possible to use Global Cable in HarcodedMasterFX?

[griffinboy]

@JulesV

I think it struggles in that case, unless it was coded in c++

[Christoph Hart]

@griffinboy nope should be fine, I think the issue is if you load the compiled fx into a network instead if a hardcoded fx module.

[HISEnberg]

@Christoph-Hart I can vouch for this I've been using them in my hard-coded fx without issue !

[JulesV]

Yes I was also be able to load it in Hardcoded.

However, on initialization, it gives the error undefined parameter for this.data.value

Why it does that?

const var MyPnl = Content.getComponent("MyPnl");

const var rm = Engine.getGlobalRoutingManager();
const var mc = rm.getCable("dlyDuckGR");

mc.registerCallback(function(value)
{	
	MyPnl.data.value = Engine.doubleToString(Engine.getDecibelsForGainFactor(value), 1);
	MyPnl.repaint();
}, AsyncNotification);

MyPnl.setPaintRoutine(function(g)
{
    g.setFont("Arial", (12)); 
    g.setColour(Colours.white);
    g.drawAlignedText(this.data.value, [71, 0, 60, 20], "left");
	
});

@JulesV possibly a timing issue - the paint routine might be executing (on init) before the Global cable has had a chance to send a value, or before the panel has had a chance to load its data...try checking your this.data.value is defined...

@JulesV I seem to remember getting that too but everything worked fine, the project would compile and export. @Lindon's explanation seems plausible.
