Is it possible to add <scene> dynamically?

Hi eveyone!

I remember from this thread https://krpano.com/forum/wbb/index.php?p…scene#post58626 that it's possible ro remove the <scene> dynamically.
But is it possible to add a scene dynamically? For example, I have 'tour.xml' with no <scene> nodes at all and I want to add them dynamically at startup and then load them using 'loadscene();' action.

I tried using scene.createarrayitem('scene0'); action and it seems that it adds the scene (scene.count increases and I can trace 'scene[0].name' in the log), but when I try to load that scene via 'loadscene();' action, it says 'ERROR: loadscene() - scene "scene0" not found"...
Regards,

Alexey

Yes you can .

you do not need to do it via createarrayitem.

just do :

set(scene[yourName or index].name, yourName);

and then the same with the content


set(scene[yourName or index].content, view - image - hotspots .... the normal content of a pano, which of course can be dynamically generated via txtadd or calc...);

Thanks, guys!

It works! *tongue*


Source code

 
1

set(scene[0].name, 'scene0');		set(scene[0].content, 			<preview url="panos/bisque/bisque_marble01.tiles/preview.jpg" />						<image>				<cube url="panos/bisque/bisque_marble01.tiles/pano_%s.jpg" />			</image>		);



Source code

 
1

scene.createarrayitem('scene0');
works also.

P.S. Why the forum always screws up the 'source code' insertion? *blink*

Alexey

Hi,

just a question..
Why would you want/need to add a scene dynamically?
I can hardly think of any reason.
Can you explain?

Yep, sure.

The idea was to change tour structure (amount of panos, their order etc.) 'on the fly' without need to go into tour.xml and copy-paste or delete <scene> nodes. Just experimenting with this though...

Hi,

just:

Source code

 
1

set(scene[NAME].content, '...');
would be enough.

When adding some custom attribute to all <scene> element, it would be also possible to use that for sorting - e.g.

Source code

 
1

scene.sortby(customattributename);

See here about 'sortby':
https://krpano.com/docu/actions/#array.sortby

Best regards,
Klaus

you can generate the tour from an array, so dynamically generate a new tour depending on variables, it's about flexibility.

Hi,

if you just want to load a scene from a different xml you could use the 'loadpanoscene' action:
https://krpano.com/docu/actions/#loadpanoscene

But for loading an other xml, extracting the scene and adding it, that would need to be coded manually - here a quick and simplified sample how such could be eventually done:

<action name="loadfirstscenefromotherxml" type="Javascript"><![CDATA[

    krpano.loadFile("othertour.xml", function(loader)
    {
        var xmlstring = String(loader.data);

        var i_scenebegin = xmlstring.indexOf(">", xmlstring.indexOf("<scene")) + 1;
        var i_scenend = xmlstring.indexOf("</scene>", i_scenebegin);

        var scene_xml = xmlstring.slice(i_scenebegin, i_scenend);

        krpano.set("scene[test].content", scene_xml);
    });

]]></action>


Best regards,
Klaus

Thank you but it seems like I didn't explain myself right.
My intention is designing a project with a combobox that creates hotspots dinamically. Those hotspots will appear located in a map. With a "Make Scene" button a new scene must be created containing all the previously selected places from the combobox. All the scenes are already located in folders named like the places, for example, if I select from the combobox "Office" and then "House" two hotspot will be created on the map named "Office" and "Hotel" and if I press "Make Scene" a new scene will be created with the content (scene[name].content) of the "Office" and "Hotel" scenes wich are located at folders named "office/tour.xml" and "hotel/tour.xml". That way the user can navigate through the selected sites in only one scene, that makes it ideal for a VR tour.
I attach a picture with a sketch to make it clearer.
Best regards.
Fernando.
