Updating with XML in FS9

[quaildog]

I am new to working with XML and gauges. I am needing to change values at other times than at a mouse click. I need to be able to do it with an element.

The first thing I am doing is having one gauge setting L: variables for another gauge. The mouse click works but, at startup, I am wanting to set defaults. I have seen simular code in FSX and I am trying to adapt the logic to FS9. I have been trying the following:

//---------- Initialize Local Values ----------//

<Element>
<Update>

(L:Init) 0 == if{
1 (&gt;Lisplay Scale)
1 (&gt;L:MapItem Shown)
2 (&gt;L:EFIS Mode)
1 (&gt;L:Init) }

</Update>
</Element>

I have tried removing the <Element/> as this is the first statements in the gauge and I have removed the condition which I thought would have just made these constants. It looks like this whole <Update/> group is just being ingored.

thanks,

<Update> cannot be inside an <Element>...</Element> section...

Also, all custom variables require a unit tag: (L:var,unit)

And please, use the # Icon to wrap your XML inside the forums' "code" tags so it's easier to read...

//---------- Initialize Local Values ----------//
<Update>
     (L:Init,bool) 0 ==
       if{ 
          1 (&gt;Lisplay Scale,number)
          1 (&gt;L:MapItem Shown,number)
          2 (&gt;L:EFIS Mode,number)
          1 (&gt;L:Init,bool) 
         }
</Update>

I think I tried this before but I will try it again. I know I tried removing the <Element> statements and I know I removed the condition completely. But I will give it another shot.

thanks,

Yes, that worked. I had not specified type on any of the L:vars. But this leads to another question.. If <Update> cannot be inside an <Element>, is there only one <Update> statement and that at the beginning? Or, can there be mulitple <Update> statements with all of them before any <Element>? Or does it make any difference as long as it is before <Mouse>?

thanks,

You may have as many <Update>...</Update> sections as you wish, provided they are on the same level as <Element> pairs...

...in other words, they must be stand-alone.

EDIT: I've since found out that the above is NOT TRUE! You may have only one <Update> section per gauge...

However, as a matter of adhering to the KISS principle, I have only ONE <Update> area per gauge script.

Remember that the "code" is executed sequentially from top to bottom, so by having the <Update> section at the top of the script, it will be done first...

I probably will have only one also unless there is a situation where it would be executed more than once depending on other switches.

thanks

Mr

<Update> cannot be inside an <Element>...</Element> section...

Is there some document that contains these little nuances related to XML gauge programming. I've read through the SDK and the tutorials and these kinds of things seem to be missing

Honestly there is not. Most everything has been posted at one time or another already, albiet scattered amongst many hundreds of posts, forums, and newsgroups...
