Confusing screentosphere... and delayed call?

Hi,

I'm getting different results on the javascript version compared to the flash version of krpano.

This is called from javascript:

Works on Flash, not on KrpanoJS, Note: I put values in there, not variables:

var mousex = krpano.get("mouse.x");
var mousey = krpano.get("mouse.y");
var spherical_coordinates = krpano.get("screentosphere("+mousex+","+mousey+")"); //convert x/y in ath/atv
var coordinates_array = spherical_coordinates.split(",");

According to the docs, you need to put variables in there, not values. But since I got an array returned, I though I dont have to provide the other 2 parameters (the variables krpano will set)
So I put variables in there:

var spherical_coordinates = krpano.get("screentosphere(mouse.x, mouse.y)"); //convert x/y in ath/atv
 var coordinates_array = spherical_coordinates.split(",");

But I get a ["NaN", "NaN"] in flash, and a null on KrpanoJS

This works on both, but the variables arent available yet after the call..

krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical)"); //convert x/y in ath/atv
var _ath = krpano.get('sphere_horizontal');
var _atv = krpano.get('sphere_vertical');

first I though because screentosphere needs some time to calculate. But doing a

krpano.cal('set(test, 10)'); 
krpano.get('test'); //returns null

I get the same problem. The variable isnt available right after the call, but doing the same get command in the terminal gives me the 10.

krpano.set('test', 10);
krpano.get('test'); //return 10

Directly setting works though. But since I have to use a call for the screentosphere, I can't use a get :(

So my question, what is the right way, that works on both KrpanoJS and SWF, so that given an x/y coordinate, returns the ath/atv immedietly.

other question, but not important, why does screentosphere expect different values in different context?

Update:

Ok stranger results:

krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical); showlog(); trace(sphere_horizontal)"); //convert x/y in ath/atv
var _ath = krpano.get('sphere_horizontal');
var _atv = krpano.get('sphere_vertical');
krpano.call('trace(js: '+_ath+')');

Tracelog:

INFO: -72.42665479744863
INFO: js: null

the trace that gets called later, doesnt have the same value...

Hi

I still haven't found a good solution for this, other then a timeout...

var mousex = krpano.get("mouse.x");
            var mousey = krpano.get("mouse.y");
var coordinates_array = [];
var spherical_coordinates = krpano.get("screentosphere("+mousex+","+mousey+")"); //convert x/y in ath/atv
if(spherical_coordinates){
	//works for flash
	coordinates_array = spherical_coordinates.split(",");
} else {
	//try different tactic for ipad
	krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical);"); //convert x/y in ath/atv
	
	//this next line is called before krpano is done, so delay it.
	setTimeout(function(){
		var _ath = krpano.get('sphere_horizontal');
		var _atv = krpano.get('sphere_vertical');
		coordinates_array = [_ath, _atv];
	}, 200);
}

Anyone knows a more reliable way?

this could help but I'm using javascript and use a modular object/class setup. So my call would be something like:

krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical); js(Tour.Hotspotview.move());");

And I remember that there was some issues in nested object functions like this. So I would need to register some function to the window object

krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical); js(screentospherecallback());");


window.screentoscpherecallback = function(){
   Tour.Hotspotview.move();
}

It's a kind of coupling I dont really prefer. Perhaps I could loosely couple it with an event instead of function callback... hmm

Would this suggestion alsoo work in javascript or is js() the only way to do an javascript call?

var callback = function(){
   //handle it
}
krpano.set("mycallback", callback);
krpano.call("screentosphere(mouse.x, mouse.y, sphere_horizontal, sphere_vertical); mycallback();");
