Hey everyone.

Does anyone know if there is a way to get the amplitude of the sound at the current time as it plays?

I know about these:
sound.amplitude
sound.amplitudeLeft
sound.amplitudeRight

but those don't update as the sound plays. they are static.

I'm trying to visualize sound based on it's current waveform volume, and there doesn't seem to be a way to do that in the FlxSound interface?

Anyone have any ideas? Thanks!

Hi, Hersir!
I'm developing a game built on FlxNestedSprite. The group positioning/scaling/rotating is really convenient, and is the kind you are looking for.

I can tell you my work around for your "Every Child Must be a FlxNestedSprite" issue.
I just created a base class that extends FlxNestedSprite, that has some logic built in to copy any other sprite, either on load, every frame, or when you need it to.

For example, FlxText, which cannot be added directly as a child to a FlxNestedSprite. I just use this helper class:

package sprite;

import flixel.addons.display.FlxNestedSprite;
import flixel.text.FlxText;
import flixel.util.FlxColor;

class FlxNestedTextSprite extends FlxNestedSprite 
{
	
	private var text:FlxText;
	private var fontPath:String;
	private var message:String;
	private var textBoxAlign:String;
	private var size:Int;
	private var textColor:FlxColor;

	public function new(message:String, fontPath:String, 
                            size:Int=10, textColor:FlxColor=FlxColor.WHITE, 
                            textBoxAlign:String="left") 
	{
		super();
		
		this.message = message;
		this.fontPath = fontPath;
		this.size = size;
		this.textColor = textColor;
		this.textBoxAlign = textBoxAlign;
		
		text = new FlxText(0, 0, 0, message);
		text.setFormat(fontPath, size, textColor, "left");
		
		copyFlxTextToSprite(this, text);
	}

	private function copyFlxTextToSprite(destinationSprite:FlxSprite,
                                             sourceText:FlxText):Void
        {
		sourceText.drawFrame(true);
		destinationSprite.loadGraphicFromSprite(sourceText);
	}
	
}

If you need to add some other non-FlxNestedSprite as a child, you can do something similar.

Hope that helps!
