I'm using the following for this tour: http://exposedbykevin.com/index.php/360viewer/oil-barons-dream-home.html
In the Main xml file at the top.
<krpano version="184.108.40.206" logkey="false" onstart="bombtimer(0)">
ifnot(stopSequence === undefined,interruptAnimation(););
<events onmousedown=" set(bt,0); "/>
<events onkeydown=" set(bt,0); "/>
if(bt == 60, set(bt,0); nextscene();, );
In the individual pano xml files I added the set(nextpano,xml file name) line to the onxmlcompleteaction, and manually enter the next pano name.
There's probably a better way to use a list/array of variables in the main xml and just move through the list.
If you want to use the lookat commands, you need them in the index0+.xml files and leave the index.xml untouched. I found the lookat commands a pain, so I use a timer and auto rotation.
I hope that helps.
