linking slider to a simplegain, the other way around.

[Jeetender]

i have a filmstrip of a vumeter on a slider, iam just tryin to effect the slider values with the value of the peak on a simplegain, iam using the getAttribute function ,but the console says function now found. i could have used a matrixpeakmeter with laf to run the filmstrip but this is just how i want to do it.

const var SimpleGain = Synth.getEffect("SimpleGain1");
const var vumt = Content.getComponent("vumt");

const var VUTimer = Engine.createTimerObject();
VUTimer.setTimerCallback(function()
{
    var peak = SimpleGain.getAttribute(SimpleGain.Peaks);
    vumt.setValue(peak);
});
VUTimer.startTimer(30);

@Jeetender I don't think the SimpleGain has an attribute named Peaks

SimpleGain.getAttribute(SimpleGain.Peaks)

//    try
SimpleGain.getAttribute(SimpleGain.Gain)

@Jeetender Use a peak meter floating tile and look and feel.

@David-Healey i tried it, also took reference from a snippet, but the filmstrip is flickering ...

@ulrik its not reading .gain too..

@Jeetender SimpleGain.Gain, not SimpleGain.gain, it should have a uppercase G

[Jeetender]

onst var SimpleGain = Synth.getEffect("SimpleGain1");
const var vumt = Content.getComponent("vumt");

const var VUTimer = Engine.createTimerObject();
VUTimer.setTimerCallback(function()
{
    var peak = SimpleGain.getAttribute(SimpleGain.Gain);
    vumt.setAttribute(vumt.Value, peak);
    Console.print(peak);
});
VUTimer.startTimer(80);

its reading the gain values and printing the gain value on the console as i move the gain knob on teh simplegain module,

const laf = Content.createLocalLookAndFeel();

laf.loadImage("{PROJECT_FOLDER}vumeter.png", "VUMeter");
laf.registerFunction("drawMatrixPeakMeter", function(g, obj)
   {
	var a = obj.area;
	var z_value = 0;
	var frames = 128;
	var zerpnt = 90;
	
	for (i = 0; i < 2; i++)
	{
		var z = obj.peaks[i];
       	if (z <= 1.0)
		z_value = Math.round((zerpnt - 1) * z);
       	else if (z > 1.0 && z <= 1.413)
		z_value = Math.round((zerpnt - 1) + (frames - zerpnt) * (z - 1.0)/0.413);
	else
		z_value = frames - 1;
		g.drawImage("VUMeter", [i * 150, 0, 128, a[3]], 0, 80 * z_value);					
	}
});

const var FloatingTile1 = Content.getComponent("FloatingTile4");
FloatingTile1.setLocalLookAndFeel(laf);

@Jeetender You can do this without a filmstrip

There's a working example here: https://forum.hise.audio/topic/13154/knob-web-studio/66?_=1777296953372
