I've been recently trying to make a script that will create some lovely sigmoid curves to fade in and out of audio files as they are called up in my Max patches. I've realized that I will have to use the Task object to do this, and while exploring it I have run into a problem. When trying to call a value, it returns "js: jsobject -1266632755061632" and such. Even with the simplest code such as:

function bang() {
    var task = new Task(testing, this);
    var value = task.execute();
    post(value);
}

function testing() {
    var value = 1;
    return value
}


Any idea of how to fix this? Thank you very much for your help.

task-object-returning-js-object-instead-of-value

Where did you get the idea to do it this way? How could it return value if you're calling execute() and not testing() itself where the return statement is??

function bang() {
    var task = new Task(testing, this);
    task.execute();
}

function testing() {
    var value = 1;
    post(value);
}


Or if you only want value once at the beginning as would happen in your original code, though I don't think this is what you want:

var value;

function bang() {
    var task = new Task(testing, this);
    task.execute();
    post(value);
}

function testing() {
    value = 1;
}



function bang() {
	var task = new Task(testing, this);
	task.execute();
}

function testing() {
	var value = 1;
	post(value);
}


var value;

function bang() {
	var task = new Task(testing, this);
	task.execute();
	post(value);
}

function testing() {
	value = 1;
}



I was mostly exploring the scheduler in normal Javascript and then task in MaxMSP.

Although your methods work in general, they wouldn't work with what I'm trying to do as I want to be able to have several of these instances with different values at the same time. Any ideas on how to do that or do I need to completely rethink that part of the code?

Sorry I didn't look at the full code you posted originally, just the example.

After looking at it though I'm more confused about what you're trying to do, why did you decide you had to use Task() and what exactly are you trying to get your js to do? There are a few things that I don't understand, like you using val_name in your switch when it's not declared anywhere in the code? And why are you declaring variables inside the switch, then making redundant assignments?

Sorry I was perhaps quite unclear, been way too much work recently, but thanks for taking the time to try to understand.

I'm currently re-writing some older Maxpatches for use in mixed music, and I'm now trying to use Javascript to control a lot of the variables. I'm trying to make a function that will create curves to fade in and out of sound files. Therefore I'm trying to make a function that can receive the name of soundfile/buffer (ie val_name), the min value (mini), the max value (maxi), the amount of time (t_amount) and in how many steps this should be done. From my basic understanding of Javascript in MaxMSP, such time-based operations have to be done with the task object, correct?

I've been thinking that it would probably be much easier to just create a few expr objects, but I'm using this as a way to teach myself to use Javascript as well.

Sorry I didn't realise you were passing val_name as an argument, my bad.

I think I see what you're trying to do, you need to simulate your for loop with Task.

your steps argument should be used to set the amount of times the Task should repeat and (t_amount/steps) should be used to set the Task interval.

I don't have time to give your code the complete rewrite that it needs, just go through the JS Task tutorials and learn more about how it actually works and is used.

I managed to do it with a mix of JS and poly~. I'm posting it here so that if anyone would happen to wonder how to do something of the kind.
