[virtual tour] Load a specific scene at startup

gn0o0b

Hello,

I recently upgraded my krpano licence. The code below used to work when I didn't want to start with the first scene in the tour.xml. But it doesn't anymore, it always starts at the first scene of my xml. I looked on the web and the doc, I'm sure I miss an obvious thing, but after different tries I can't manage to choose my first scene. If somebody could help me that would be great :)

Code

    <action name="startup" autorun="onstart">
		if(startscene === null OR !scene[get(startscene)], copy(startscene,scene[0].name); );
		loadscene(THE_SCENE_I_WANT), null, MERGE);
		if(startactions !== null, startactions() );
	</action>

Hi,

that's independent of the krpano viewer version ,but depends on what version of vtourskin.xml you use.

E.g. in the current vtourskin.xml (version 1.21) the startup scene loading is done the in the vtourskin.xml in this action:

Code

<action name="skin_onstart_loadscene" scope="local" autorun="onstart">
	
	<!-- load first scene -->
	loadscene(calc(isset(startscene) ? startscene : 0), null, MERGE);

	<!-- set optional startup lookat -->
	if(isset(startlookat),
		txtsplit(startlookat, ',', hlookat,vlookat,fov,distortion,architectural);
		lookat(get(hlookat),get(vlookat),get(fov),get(distortion),get(architectural));
	);

</action>

That means with this version, no startscene loading the tour.xml wouldn't required.

Additionally it would be important that in the html file, the passQueryParameters setting includes "startscene", otherwise this url-query wouldn't be passed into the viewer:

Thank you Klaus, I'm gonna concentrate on your answer and make all that work.

Thank you very much for that quick answer :)

Me again :/

I guess it's because of the new way of vtourskin dealing with loadscene but this part of code used to work but doesn't anymore.

Code

    <action name="mouse_click" scope="global">
        calc(scene_nbr_var, substr(scene_nbr,6));
        calc(scene_nbr_var1, 3 + scene_nbr_var);
        loadscene(*scene_nbr_var1, null, KEEPVIEW, BLEND(0.1));
    </action>

If I trace scene_nbr_var1 the value is ok, krpano loads the good scene but the second after it loads another one. The reason I have a "+3" is because I have videos on the beginning of the xml scenes and I don't want them to be loaded automaticly, but now krpano loads the good scene then the second after it plays the video.

You would need to show either a full example or track yourself what you're doing ;-).

krpano wouldn't load another scene a second later by itself, there must be an explicit call doing that.

Thank you for that quick answer, you're probably right, I'm gonna check all the code, I must admit I did so many changes I'm not sure I pasted all of them on the new files... Headache in perspective :)

I couldn't explain why but after removing the piece of code below which I didn't have in older version, things seem to work :)

It's in the new vtourskin at the "skin_hotspotstyle_click"

Code

if(caller.use3dtransition,
				skin_scene3dtransition(get(hs_linkedscene),get(caller.linkedscene_hoffset));
			  ,
				tween(caller.depth|caller.alpha|caller.oy|caller.rx, 4000|0.0|-50|-60, 0.5, default,

Jetzt mitmachen!
