XML gauge conflict?

[Dave_W]

This is in a VC in FSX.

This is supposed to be an oil transfer system. The oil goes from a reserve tank to one of four engine tanks. The oil quantities are stored between sessions using dsd_xml_config.

To transfer oil, you open a 2D window, click on a tank number selector gauge which sets (L:TANK NUMBER, number). Then click on another switch which sets (L:PUMP SWITCH,bool).

In this same window, and only in this window, there is a gauge that decrements at a specific rate as the
reserve tank oil quantity decreases.

That gauge appears to do what I want it to with the following code:

<Gauge Name="Res_Oil_Tank_Level" Version="1.0">
   <Image Name="tank_level_back.bmp"/>
   
<Element>
   <Position X="128" Y="128"/>
   <Image Name="tank_level_needle_bevel.bmp" PointsTo="North">
  <Axis X="18" Y="65"/>
  </Image>
  <Rotate>
  <Value Minimum="0" Maximum="50">
     (L:TANK NUMBER, number) 0 &gt; (L:PUMP SWITCH,bool) 1== &amp;&amp;
     (P:ABSOLUTE TIME, seconds) (L:START TIME, seconds) - 10 &gt; &amp;&amp;
     if{ (P:ABSOLUTE TIME, seconds) (&gt;L:START TIME, seconds)
     (L:RES OIL QUANTITY, gallons) -- (&gt;L:RES OIL QUANTITY, gallons) } els{ (L:RES OIL QUANTITY, gallons) }
   </Value>
  <Nonlinearity>
  <Item Value="0" X="84" Y="97"/>
  <Item Value="10" X="100" Y="87"/>
  <Item Value="20" X="117" Y="80"/>
  <Item Value="30" X="135" Y="80"/>
  <Item Value="40" X="153" Y="84"/>
  <Item Value="50" X="174" Y="95"/>
  </Nonlinearity>
  <Delay DegreesPerSecond="25"/>
  </Rotate>   
</Element>
<Mouse>
  <Area Left="20" Width="200" Top="150" Height="80">
  <Tooltip>Reserve oil quantity (%((L:RES OIL QUANTITY, gallons))%!d! GALS) Click to fill </Tooltip>
  <Cursor Type="Hand"/>
  <Click>(A:GENERAL ENG COMBUSTION:1, bool) ! (A:SIM ON GROUND, bool) &amp;&amp; (A:BRAKE PARKING POSITION, bool) &amp;&amp; if{ 50 (&gt;L:RES OIL QUANTITY, gallons) } </Click>
  </Area>
</Mouse>   
</Gauge>

That's all for the 2D window.

In the VC, I have two, dual needle engine oil quantity gauges. The gauge for the engine chosen for the
transfer by (L:TANK NUMBER, number) increments at a specific rate if (L:PUMP SWITCH,bool) is on.

The following example code is taken from the engine one part:

  <!-- ========================= Oil Qty - engine 1 =================== -->
  <Element>
  <Position X="128" Y="128"/>
  <Image Name="Oil_Qty_L_Needle_4_256.bmp" PointsTo="North">
  <Axis X="12" Y="99"/>
  </Image>
     <Element>
       <Select>
        <Value Minimum="0" Maximum="22">
           (L:TANK NUMBER, number) 0 > (L:TANK NUMBER, number) 2 &lt; &amp;&amp;
           (L:PUMP SWITCH,bool) 1== &amp;&amp; (P:ABSOLUTE TIME, seconds)
           (L:START TIME, seconds) - 10 &gt; &amp;&amp;
           if{ (P:ABSOLUTE TIME, seconds) (&gt;L:START TIME, seconds)
           (L:ENG1 OIL QUANTITY, gallons) ++ (>L:ENG1 OIL QUANTITY, gallons) }
         </Value>
       </Select>
     </Element>   
  <Rotate>
     <Value>(L:ENG1 OIL QUANTITY, gallons)</Value>
     <Nonlinearity>
  <Item Value="0" X="71" Y="211"/>
  <Item Value="5" X="32" Y="97"/>
  <Item Value="10" X="88" Y="35"/>
  <Item Value="15" X="162" Y="33"/>
  <Item Value="20" X="216" Y="80"/>
  <Item Value="22" X="227" Y="115"/>
     </Nonlinearity>
     <Delay DegreesPerSecond="25"/>
  </Rotate>
  </Element>

This code appears to do what I want it to only if I comment out the reserve oil tank quantity gauge that is in the 2D window. If I don't do that, the engine quantity gauge in the VC won't increment.

I hope this is enough information to show what the problem is. Can anyone see something wrong?

TIA

Sorry, no time now to understand what the code exactly does.
But I notice on two places that you use "1==" instead of "1 ==" So a missing space.
Not sure if the space is required (looks more clear with a space anyway) but you can try ..

Try what Rob said.
Also rename (L:START TIME, seconds) in the VC gauge to (L:START TIME2, seconds) to deconflict the timers used for controlling oil quantity in the tanks.

The space is mandatory, otherwise 1== is being discarded by the parser.

However in this specific case is not a factor, because (L: PUMP SWITCH,bool) can hold 0 or 1, so there is no need to compare against "1 ==" or "0 ==". As 1== is not being stored on the stack, what is evaluated is (L: PUMP SWITCH,bool) alone.

Bjoern nailed it. (L:START TIME, seconds) must be renamed in the VC gauge. (P:ABSOLUTE TIME, seconds) (>L:START TIME, seconds) is first executed in the 2D panel gauge therefore (P:ABSOLUTE TIME, seconds) (L:START TIME, seconds) - 10 > in VC gauge will never execute as True (1).

Thanks Bjoern.

Tom, thanks for explaining everything.

I don't know enough about using the forum, or I would mark this thread as solved.

Edit: Rob, thanks also. It was a bit early in the A.M. when I replied.
