Hello my fellow AVSIMMERS,I have been recently trying to make my in-flight data gauge change screens say every 10 seconds using the same bitmap image, with little success so far. For example "Screen 1" should be displayed for 10 seconds (with 3 Element - 3 GaugeText), "Screen 2" displayed for 10 seconds (with 3 Element - 3 GaugeText) and so on... I tried using a local variable (L:ChangeScreenTimer, seconds) and the same variable with type number. Furthermore I even experimented with (E:ABSOLUTE TIME, seconds), both of my methods have not been successful so far. Also I believe my <Update> section of code (given below) might have a bug when it comes to looping the screen number back to the start.Is it even possible to do this or can I "trick" the ACE tool to come up with this effect?Could somebody help me please?ThanksAdrian

Adrian, 1st to start, I'm not totally comfortable with the FSX XML format, nor do I like it compared to FS9 format. But anyway it works just the same. :( I did notice you only have 2 elements ( so far? ) to be switched... you only have <Element><Visible> values of 0 & 1. Following is a tip for "grouping / nesting" when multiple <Elements> are controlled equally. For coding wise and such... (FS9 style )

<Element Name = "VISIBLE SECTION WHEN ZERO" ><Visible>0</Visible>              <Element Name = "My 1st part visible when zero">                   some stuff in here             </Element>              <Element Name = "My 2nd part visible when zero">                   some stuff in here             </Element> </Element><Element Name = "VISIBLE SECTION WHEN ONE" ><Visible>1</Visible>              <Element Name = "My 1st part visible when one">                   some stuff in here             </Element>              <Element Name = "My 2nd part visible when one">                   some stuff in here             </Element> </Element>

Now for the switching part in "psuedo 9 /10 " XML code. Renamed vars for clarity. CAUTION!!! on some of my old code timing structures donot work no more as FS9 absolute time seems like it's DECREASING!! ( still working, testing, verifying this when I have time, so donot quote me on this ) This code "should" handle it both ways.

<Update id="Update"><script><!-- Initialize all vars on 1st read & set INI to 1, set timer, 1st screen is already set @ 0 -->(L:INI , number) 0 == if{ 1 (>L:INI , number) 10 (P:Absolute Time, Seconds) + (>L:Timer, Seconds) }<!-- Do stuff once intialized -->(L:INI , number) 1 == if{ <!-- Trigger stuff once timer is up -->(L:Timer, Seconds) (P:Absolute Time, Seconds) - abs 10 > if{ <!-- Reset trigger timing -->10 (P:Absolute Time, Seconds) + (>L:Timer, Seconds) <!-- Increment visible values ( USING 3 visibles here ( 0-2 ) -->(L:Screen, number) 2 == if{ 0  (>L:Screen, number) } els{(L:Screen, number) ++ (>L:Screen, number) }}}</Script></Update>

There is probably a more efficient way to do this & it has not been tested fully, basic code/struture has. Anyway...Hope this helps, Roman

Thanks Roman for the very helpful solution, much appreciated.I tried another approach to my problem and put <select> and <case> statements for each <GaugeText> item I want to display. Will try your method and mine and I will see how it goes.CheersAdrian

Hello everybody,I am still confused as to why my gauge is not changing screens via a timer.As you explained Roman that I should use nested <Element> structures with the appropriate <Visiibility> condition and the use of an <Update> script to control the timing of screens using (P:Absolute time, seconds). Furthermore you mentioned that "trigger stuff once timer is up", do I have to write code that points to my <Element>, <GaugeText> tags or just a comment that explained the proceeding statement of code.When I tried out your solution it still stays on "Screen 0" and does not proceed to the next screen let alone loop.The (P:Absolute time, seconds) variable stays at 0 or a negative number when used :( . I then proceeded to use (E:LOCAL TIME, seconds) as it did show when testing the time incrementing.Here below is the XML code for the project. Any bugs?I experimented with some code with the <Update> script using (E:LOCAL TIME) given below in infix notation.XML code:

Is the XML code a top down language? If not, does that mean I can place my tags in any order?Does the <Update> tag run at the same time as <Element>, @Macro etc. or before?Adrian

Adrian,

Is the XML code a top down language? If not, does that mean I can place my tags in any order?Does the <Update> tag run at the same time as <Element>, @Macro etc. or before?

This is how i do it, in general it is top --> bottom.-For general coding style it's best to have Macros the very top but just below the background image (if there). Easier to find / track. -Have the update section next. You want to update all the data before you display/control something. The order you do the coding in update is very important in complex gauges.-Element sections next, display(s), switches etc...-Area/Mouse section at the end.In the update section code I did find a few bugs, including one of my own. ( Sorry :( ) I noticed these,- (L:ScreenNumber, number) (L:ScreenNumber, seconds) might work, probably not though, better just to keep value type the same.- It's not a good idea to have a timer to equal time to trigger something. 3.1234 seconds is not the same as 3.1235. Better to find the difference and trigger when larger than a value. ( That's where I bugged it :( )- Donot know what this is or what you were trying.......... && if{ 0 -- (>L:ScreenNumber, number) ..... or (L:ScreenNumber, seconds) (E:LOCAL TIME, seconds) 10 + ++ (>L:Next, seconds)Anyway keep plugging at it, it'll come to you. :( When things donot work after many tries sometimes I get further away from the intended code. Best just start from scratch again. B) Attached is a text file with both FS9 (tested fully) and FSX (not tested) code for the update section. Should be able to just copy and paste into your gauge. I kept the variable names the same as yours. Hope it helps.UPDATE - the forum wont upload it so it's here in the codebox..Watch spaces when copiing....

<!-- FS9 --><Update>(L:Init, number) 0 == if{ (E:LOCAL TIME, seconds) (>L:Timer, seconds) 1 (>L:Init, number) } (L:Init, number) 1 == if{ (L:Timer, Seconds) (E:LOCAL TIME, seconds) - abs 10 > if{ (L:ScreenNumber, number) 2 == if{ 0 (>L:ScreenNumber, number) (E:LOCAL TIME, seconds) (>L:Timer, seconds) } els{ (L:ScreenNumber, number) ++ (>L:ScreenNumber, number) (E:LOCAL TIME, seconds) (>L:Timer, seconds) } } }</Update>        <!-- FSX --><Update id="Update"><script>(L:Init, number) 0 == if{ (E:LOCAL TIME, seconds) (>L:Timer, seconds) 1 (>L:Init, number) } (L:Init, number) 1 == if{ (L:Timer, Seconds) (E:LOCAL TIME, seconds) - abs 10 > if{ (L:ScreenNumber, number) 2 == if{ 0 (>L:ScreenNumber, number) (E:LOCAL TIME, seconds) (>L:Timer, seconds) } els{ (L:ScreenNumber, number) ++ (>L:ScreenNumber, number) (E:LOCAL TIME, seconds) (>L:Timer, seconds) } } }</Script></Update>

Thanks again Roman for the tips and the words of encouragement :( . I probably a real pest to everybody with these posts. It's lucky that I have'nt gone nuts over this part of the project. I am hoping when I get this changing of screens going ok, then I can proceed into using a 2D map of the world to map the flight plan, which I think it would be cool. :( . When this project is hopefully done i will release it to download.Does anybody do any beta testing on gauges? I might scare people off because it took me ages to get to this stage :( .Adrian

That was the functionality I needed to change screens thats a million. Now I can generalise the code to any number of screens.Now no more blisters on my brain :)Adrian

Adrain, Glad it worked ! If you noticed though I forgot to change the timing back to 10 seconds :( Roman

RomanIs this what you meant about the timing resetting back to 10 seconds, after (L:Init, number) == 1 always?10 (E:LOCAL TIME, seconds) + (>L:Timer, seconds)Adrian

Adrian, No I had posted my test code where i reduced the timing to 3 seconds before a switch..... (L:Timer, Seconds) (E:LOCAL TIME, seconds) - abs 3 > ....I edited the post to put it back to 10.... (L:Timer, Seconds) (E:LOCAL TIME, seconds) - abs 10 > .... Hope I didn't confuse you.Roman
