if / else

Hi,

the url of the current xml is stored in the "xml.url" variable,
so you could do:

if(xml.url == '3.xml', ...);

best regards,

Zitat von Tuur

Hi ,

I like to do an if /else thing (in xml)... so that it gets if a certain panorama (xml) is loaded...

for example:

Code

<action name="areasur">
set(area4,get(pano[3.xml].visible));
		if(area4  == false, set(plugin[surounding].visible,false);, set(plugin[surounding].visible,true);
</action>

Tuur,

In your code example, you're trying to use an array and addressing it with the xml name. Great idea, but unfortunately this won't work for a couple of reasons: 1) names of array elements can't contain a period 2) in your example, names of array elements can't start with a number.

Problem 1 could be addressed by using the basename of the xml file name (the part of the name before the .xml). Problem 2 could be addressed by prepending the names of the array with a character or string (for instance _1 or pano_1).

As far as I know, extracting the basename for your xml.url cannot be done in the krpano action language without going into javascript. It would be nice if Klaus provided a xml.basename attribute and/or a %BASENAME% macro that would resolve everywhere (not just in url attributes). I actually use this technique and preprocess the xml files using perl to get the basenames.

Some other ways to accomplish this:

1) Write an onxmlcomplete function which uses if statements to set the visible attribute:

if (xml.url == "3.xml",set(plugin[surrounding].visible,true));
	if (xml.url == "4.xml",set(plugin[surrounding].visible,false));
	...

This is a little harder to maintain because you're hardcoding file names into your function, but it will work...

2) Include the surrounding plugin only in the xmls you in which you want it to appear and set keep="false"

[b]3) Include a variable in the krpano tag which you use to set the visibility

<krpano version="1.0.9" surroundingvis="true" >


<events onxmlcomplete="onxmlcomplete()" />


<action name="onxmlcomplete">
	copy(plugin[surrounding].visible,surroundingvis);
</action>
</krpano>

Of course, you'll need to remember to put the surroundingvis attribute in the krpano tag for every xmlfile.

Hope this helps.
