FSX AP Annunciator

[Doia]

For some reason my AP annunciator "ALT"won't turn on when it should.
Here's the code - if you can tell me what is wrong with it I'll give you a cookie

<?xml version="1.0" encoding="utf-8"?>
<Gauge Name="Attitude Indicator" Version="1.0">
       	<Image Name="ADI.bmp"/>

<Element id="ALT">
            <FloatPosition>305.000,178.000</FloatPosition>
            <Select>
                <Expression id="Expression">
                    <Minimum>0.000</Minimum>
                    <Maximum>1.000</Maximum>
                    <Script>(A:Autopilot altitude lock, bool)</Script>
                </Expression>
                <Case id="Case">
                    <ExpressionResult>1.000</ExpressionResult>
                    <Image Name="adi_alt.bmp">
                        <Transparent>True</Transparent>
                    </Image>
                </Case>
            </Select>
        </Element>
  
</Gauge>

Looks like I'll eat the cookie P=

Hi Doia,

I would help you, but unfortunately I am not very familiar with the 2D side of XML programming...
I am not sure if that makes any difference, but have you tried:

<Script>(A:AUTOPILOT ALTITUDE LOCK,bool)</Script>

instead of:

<Script>(A:Autopilot altitude lock, bool)</Script>

?

Good luck,
Vitus

                    <Image Name="adi_alt.bmp">
                        <Transparent>True</Transparent>
                    </Image>
                </Case>
            </Select>
        </Element>
  
</Gauge>

Why such a complex bit of script to accomplish a rather simple task?

Try something a bit simpler:

<Element>
	<FloatPosition>305.000,178.000</FloatPosition>
	<Visibility>(A:Autopilot altitude lock, bool)</Visibility>
	<Image id="adi_alt.bmp" Name="adi_alt.bmp">
		<Bright>True</Bright>
		<Transparent>True</Transparent>
	</Image>
</Element>

OTOH, XML variables are only guaranteed to return a zero; the opposite could well be not 1, but indeed a -1 (or even something more weird)...

So, it is best practice to force the return to be consistent by explicitly declaring the return this way:

<Script>(A:Autopilot altitude lock, bool) if{ 1 } els{ 0 }</Script>

Thanks again for the help guys the code works fine now with the line forcing the bool operator to return 1 or 0
oh yeah! as promised: message me your mailing address if you want to receive a cookie
