FSXA Visibility condition in AI model

[kanoasurf]

Yes the g:var 1-9, I have tried to understand how they work. I'm trying to create an animation that works in FSX to allow the flaps to be deployed after pushback. I'm sure that I will need G:var variables; I've seen Erez Werber animations and some others and seems to me that they are a bit complex, and that I will need to use g:var at some point, so the question. No a clue how thy work or how to read them as you read some of he code above...

There is a place with some info called aerodinamika.com but is impossible to access it

FFDS is basically dead in the water by now.

And as far as I know, the AI engine utilizes and sets the standard flap animation tags, so there's no need to write custom code.

It did not work for me in many conversions, that is why I started to investigate

The flaps of AI aircraft do not normally deploy on takeoff (only landing) so a custom animation is required. I use the landing lights for that, but that means they only extend their flaps just before taking the runway, not taxiing out.

Here is my FS2004 animation, using 40% deployment for takeoff:

<part>
  <name>ai_flap_vis</name> <!-- for AI aircraft  - flap is visible all the time, sets t/o flap to 40% -->
      <animation>
       <Parameter>
       <Code>  (A:TRAILING EDGE FLAPS LEFT PERCENT, percent) 0 &gt; if{ (A:TRAILING EDGE FLAPS LEFT PERCENT, percent) } els{ (A:LIGHT LANDING, bool) (A:GEAR CENTER POSITION, percent) 99 &gt; &amp;&amp; if{ 40 } els{ 0 } } </Code>
        <Lag>5</Lag>
       </Parameter>
    </animation>
</part>

The flaps will act as normal flaps if any flap is deployed (i.e. during landing). If not, then it checks if the landing lights are on and the gear is down. If so, it lowers the flaps to keyframe 40. When the gear is raised after takeoff, the flaps also come up.

If you find something that allows the flaps to be down during taxi out, let us know.

Tom

I've been messing around, and the last test has been with

  <Animation name="l_r_my_flaps" guid="9C99F8AA-5994-4633-8418-70E001B7F699" length="200" type="Sim" typeParam2="l_r_my_flapS" typeParam="AutoPlay" />
  <PartInfo>
    <Name>l_r_my_flaps</Name>
    <AnimLength>200</AnimLength>
    <Animation>
      <Parameter>
        <Code>#5#
    (A:TRAILING EDGE FLAPS LEFT PERCENT, percent) 0 &gt; if{ (A:TRAILING EDGE FLAPS LEFT PERCENT, percent) } els{ (A:LIGHT NAV, bool) (A:GEAR CENTER POSITION, percent) 99 &gt; &amp;&amp; if{ 40 } els{ 0 } }
        </Code>
      </Parameter>
    </Animation>
  </PartInfo>

Obviously, no success at all, I mean the flaps were never deployed during taxi, not even during take off.

Your code was tested in FSX?

Cheers

As far as I know, Tom exclusively uses FS9.

Hi,

As I said, it is FS2004 code.

And I work *almost* exclusively in FS9. I did create a classic gas truck that trundles around my FSX airports.

I'll keep trying
