How do I find and remove objects in an array?

[d.healey]

@VirtualVirgin For those functions (some, filter, etc.) the first parameter should be a function.

Edit: I just realised you're doing the javascript arrow function thing, we don't have that in HISE.

No, the arrow function definitely works:

Oh that's good to know, thanks!

Now I can do this kind of thing:

Engine.showYesNoWindow("A title", "Some text", response => {
	Console.print(response);
});

You could replace this

	if (sRow && sCol)
		return true;
	else
		return false;

With return sRow && sCol

But this doesn't solve your issue. Can you make a simple snippet that demonstrates the issue?

@d-healey
I found where the problem is taking place:

            selectedNotes.push
            (
	            selectedNotes.filter(function (c) 
	            {
	                var cx = c.col * cellWidth;
	                var cy = height - (c.row + 1) * cellHeight;
	
	                return 
	                (
	                    cx + cellWidth > x1 &&
	                    cx < x2 &&
	                    cy + cellHeight > y1 &&
	                    cy < y2
	                );
	            })
            );

This selectedNotes.push is pushing an object inside an array to the selectedNotes array, whereas I only need it to push an object to the array.
So the current result is looking like [[{"row":42, "col":4}]]
but I need it to just look like [{"row":42, "col":4}]
I am not sure how I modify that to just use a the object and not have it wrapped in that extra array.

@VirtualVirgin Add [0] after the parenthesis

[VirtualVirgin]

@d-healey Almost...
that turns it into an object, but it only returns one selection to the list instead of all of the noteCells under the selection rectangle area.
Without the [0] it returns all of them, but inside an array.

[d.healey]

@VirtualVirgin In that case after it returns them, just grab the [0] element from that array.

[VirtualVirgin]

@d-healey Whoops... is there a panic button of some sort for feedback loops? I got stuck in one.

[d.healey]

@VirtualVirgin What do you mean?

[VirtualVirgin]

@d-healey I added a for loop after that function and it seems to be stuck in the loop

[d.healey]

@VirtualVirgin What does the loop do?

[VirtualVirgin]

@d-healey

for (i = 0; i < noteCells; i++)
     selectedNotes.push(noteCells[i]);

It's not resolving because I meant to use "i < noteCells.length",
so I am stuck with a spinning wheel and a sluggish HISE.

I'll just force quit it.
Just didn't know if there is a button similar to "all notes off" to stop the processing.

@VirtualVirgin Can you just hit compile again?
