XML code question

[okbob]

I want to initialize the NAV and Panel lights to "off" when I load a Cessna in FSX. Both lights are controlled by the same switch. I also need to cut the throttle.

In the FSX SDK, I found an EventID to turn off the panel lights. But I could only find a "toggle" command for the Nav lights. Sooo, I thought I could simply test to see if the Nav lights were on, and if they were then toggle them.

Well, the throttle cuts, and the panel lights turn off. But not the Nav lights.

Evidently I've not coded this right, as it doesn't work. I'm out of ideas, can someone please help?
Here's my initialization code:

 <Update>
   (L:AircraftInitialize,bool) 0 == if{
	(>K:PANEL_Lights_Off)
	(A:LIGHT_NAV_On,bool) 1 == if{ (>K:TOGGLE_NAV_LIGHTS) }
	(>K:THROTTLE_CUT)
	1 (>L:AircraftInitialize,bool) } 
   </Update>

Thank you for considering my problem. Bob

Try this:

<Update>
(L:AircraftInitialize,bool) !  if{
     (>K:PANEL_Lights_Off)
     (A:LIGHT NAV,bool)  if{ (>K:TOGGLE_NAV_LIGHTS) }
     (>K:THROTTLE_CUT)
  1 (>L:AircraftInitialize,bool) } 
</Update>

I couldn't find "LIGHT_NAV_On" in the SDK variables.

Save a little typing, for boolean entities you don't need to use X ==. "0 ==" is the same as !(not), and "1 ==" requires nothing after the closing parenthesis...Don

Thank you for the fix, the tip and the explanation.
I LIKE your explanation, and the code is nice and simple.
Thank you much, Don, and happy Weds.

Don, I tried your code and it worked like a charm. I knew it would.
I found "Light_Nav_On" in "Token Variables" located in the SimObjectCreation folder of the SDK. I really don't know how to use that.
But, thanks to you, I now know to use, "Event IDs" and "Simulation Variables" instead.
Cool beans, and mille grazzie. Bob

Benvenuti! I took a gander at the SDK again, and lots of "Token Variables" aren't in the Variables listings. I would think Token Variables should work though. Odd.

I copied the gauge related sections of the SDK into a spreadsheet so I could add my own usage and examples for the oddities I've found.
No Token Variables page! That's why I didn't find "LIGHT_NAV_On". I'm adding a page now, for reference.
Try just changing that in the known good code. It may have been spacing(Important) or another little thing that stopped your original from working.
If it doesn't work, we'll know to keep a keen eye on the Token Variables we try. I'm learning too...Don

There's nothing "odd" about it. The "Token Variables" list in the FSX SDK is a list of C type variables. It has nothing at all to do with XML variables...

XML variable entries are found in the Core Utilities Kit/Variables/Simulation Variables list.
XML commands are found in the Core Utilities Kit/Variables/Event IDs list. In this document the left column are the C commands, center column are the XML K: commands, right column is the description.

Goodness! I guess it would have behooved us to read the first line on the SDK "Token Variables" page! Instant understanding...Don

Bill, thank you so much for explaining what Microsoft did not.

I recall, too, from another thread where you explained that variables are what the simulator sends to the gauge, and key commands are what the gauge sends to the sim.

All your tips, Don's too, help me sort through the obscure (to a novice) nomenclature. Cool beans.
