Loading the last scene on startup, not the first?

Hi there.

My virtual tour is currently set up to load the first scene in the array. However as I'm in the process of documenting my scenes, I want it to load the last scene in the array (the latest one added), so I can work on the hotspot of the scene immediately without having to navigate all the way through my tour.

The current code is:

Source code

 
1
2
3
4

	<action name="startup">
		<!-- load the first scene -->
		loadscene(get(scene[0].name), null, MERGE);
	</action>


I've tried replacing the line with:

Source code

 
1
2

		<!-- load the first scene -->
		loadscene(get(scene[scene.count].name), null, MERGE);


But to no avail.

Does anyone have the correct code? I'm probably missing something easy. Thanks in advance. *thumbsup*


Edit: also, does anyone have any tips on adding a "previous scene" button? I wouldn't know how to reference the last scene I was on :\.

Hi!
Scenes index from 0
so if 6 scene then last one be 5 ( 0 - 5 )
You need to sub(count,1); to get last scene index

Quoted from "mindlessboss"

sub(count,1);


Thank-you for your reply, however I'm still having trouble getting it to work. I replace the line with this:

Source code

 
1

loadscene(get(scene[sub(scene.count,1);].name), null, MERGE);


But the tour gets a null-pointer error, reference:

Source code

 
1
2

WARNING: not local trusted - ExternalInterface disabled!
ERROR: loadscene() - scene "null" not found


Do you have any ideas? Thanks again :).

Hi!
You can't use action as parametr.
so make some variable
set(var,get(scene.count)); <!-- create some variable -->
sub(var,1);
loadscene(get(scene[get(var)].name), null, MERGE);

That works perfectly thank-you!

Do you also know how to reference the previous scene I was one? I want to make a back button that I can keep clicking no matter how far I am in the tour, and it eventually takes me back to the entrance of my virtual tour. Thanks again *g*

This comes with krpano. Check the examples folder. Scenes with prev/next.
