How do I access current scene attributes and nodes?

Hi,

<scene> is special node in the xml,
only this three values can be accessed/read:

• scene[name].name
• scene[name].content
• scene[name].onstart

best regards,
Klaus

Hi, this restriction is valid also with new krpano version? no read - no acces also for this atributes?

thumburl
lat
lng
heading

Hi guys! Sorry if I understand you wrong about "get/access" for a scene's atributes, but the following stuff seems to work:

the modified "startup action:

<action name="startup">
		if(startscene === null, copy(startscene,scene[0].name));
		loadscene(get(startscene), null, MERGE);
		set(panonumber,1);
	</action>

an event to trigger a check on every new pano:

<events name="check_pano_data" keep="true" onnewpano="check_pano();" />

and the action itself:

<action name="check_pano">
	add(panonumber,1);
	if(panonumber GT 4, 
	set(scene[get(xml.scene)].title, null);
	set(scene[get(xml.scene)].thumburl, null);
	set(scene[get(xml.scene)].lat, null);
	set(scene[get(xml.scene)].lng, null);
	set(scene[get(xml.scene)].heading, null);
	);
	showlog();
	trace(title=,scene[get(xml.scene)].title);
	trace(thumb=,scene[get(xml.scene)].thumburl);
	trace(latitude=,scene[get(xml.scene)].lat);
	trace(longitude=,scene[get(xml.scene)].lng);
	trace(heading=,scene[get(xml.scene)].heading);
	</action>

The idea is that after you went through four panoramas, the title, thumburl, latitude, longitude and heading are set to "null". And I see in the log that traces return corresponding values and "nulls" after fourth loaded pano.

Hi,

attributes AT the <scene> elements can be accessed!

It's only not possible to access elements or attributes INSIDE the <scene> elements.

The reason therefore is that the content inside the <scene> elements will be not parsed during the xml loading. Instead of parsing the whole <scene> content will be stored as text inside the 'scene[name].content' variable, and only parsed when calling loadscene() for that scene. That means a scene is like an 'inline-xml'.

Best regards,
Klaus

So if I put a layer inside the <scene> and set keep="false", it will appear only when this scene is loaded? I remember I tried this way some time ago to make different photos appear in various scenes, but I rejected this way, - honestly, don't remember why exactly((

Or, I guess, this layer won't need keep="false"...

Right, that layer will appear only in that scene and disapear again when loading another scene/pano because of the keep=false (which right - is already the default and don't need to be set).
