Need a little help with (HISE) loops

[Lindon]

@gorangrooves you mis-spelt length..

MapCombos.lenght

[gorangrooves]

@Lindon Thank you. That resolved one bit, but my script is still not working. It compiles, but it doesn't do what I am expecting.

This is the latest:

for (i = 0; i < MapCombos.length; i++)
    {
		var Box = MapCombos[i];

        inline function onBoxControl(component, value)
        {
	       noteTriggers[i] = value - 1;
	       setKeyColours();
        };

		Box.setControlCallback(onBoxControl);
    }

What am I missing / doing wrong?

@gorangrooves What about putting the loop inside your function?

inline function onBoxControl(component, value)
{
     for (i = 0; i < MapCombos.lenght; i++)
     {
        var Box = MapCombos[i];
	noteTriggers[i] = value - 1;
     }
     setKeyColours();
};

Content.getComponent(Box).setControlCallback(onBoxControl);

[gorangrooves]

@Dan-Korneff Thanks, Dan. Unfortunately, that doesn't work either. It throws an error

column 21: Argument 0 is undefined! 

on this line

Content.getComponent(Box).setControlCallback(onBoxControl);

And If I put it like this:

Content.getComponent("Box").setControlCallback(onBoxControl);

I get this error on that last line:

column 47: Unknown function 'setControlCallback'

O, thou Loop Wizard, @d-healey, could you please enlighten me?

[d.healey]

@gorangrooves You can't declare an inline function inside a loop, that is just weird :p

Post a snippet and I'll fix it :)

[gorangrooves]

@d-healey Ok. Thank you. If I export a HISE snippet from my entire current project, will that work despite missing all of the images for buttons, sliders etc, as well as the actual samples?

[d.healey]

@gorangrooves Don't make one for your entire project. Just make a minimal one that demonstrates the issue.

[gorangrooves]

@d-healey Uh, I'll try. There are several intervened elements.

[d.healey]

@gorangrooves Often the process of making a simplified snippet will reveal where the true issue is - I do this all the time if I'm trying to solve an issue in a complicated project.

[gorangrooves]

@d-healey Got you. I think I'll make a copy of one of the projects, then strip it down naked

[d.healey]

@gorangrooves You might also want to look at some of my tutorials where I'm building interfaces with controls stored in arrays and how I reference those controls inside the callback.

[gorangrooves]

@d-healey I did. I love them. Everything made perfect sense. Then I attempted to make my own...the rest is history

[d.healey]

@gorangrooves Something like this

for (i = 0; i < MapCombos.length; i++)
{
	MapCombos[i].setControlCallback(onBoxControl);
}

inline function onBoxControl(component, value)
{
	local index = MapCombos.indexOf(component);

	noteTriggers[index] = value - 1;
	setKeyColours();
};

[gorangrooves]

@d-healey Thanks so much, you wizard! I think that is the way to go.

The notes and comboboxes are not quite matching at the moment, but I think I need to do some untangling, perhaps. You helped me overcome a major hurdle. Thank you so much!

[gorangrooves]

@d-healey Yes, I got it all sorted and implemented another feature to learn MIDI notes using a loop. Thanks so much again for the personal help and for your helpful videos!
