MSFS20 Here's how to write you own ModelBehavior code.

I'm not sure what you are trying to do but this has syntax errors:

Thanks, sorry for my english. It will be a code for the AI version of an aircraft, to spawn every aircraft with different nodes (objects: Doors, chocks, covers...) And, to optimize it a little bit, I'm trying to write the long instruction only once at the begginin of the xml, and use the result of that long instruction, at all other nodes (animations and visibility). The long instruction returns 0 or 1 depending the AI spawned plane position, so every plane spawns with different position objects.

If I place the long instruction on every node, it yes works properly, but it is not optimal for performance. I've tried to put that value inside myVar to optimize it a little bit, but doesn't work properly, every spawned plane uses the first spawned plane value (position coords).

So I'm trying another method to call the long instrucion value:

<Component ID="Doors">
<UseTemplate Name="xxx" Node="xxx">.....<ANIM_CODE>ALANE LATITUDE, degree latitude) (ALANE LONGITUDE, degree longitude) % 5 symb 4 ></ANIM_CODE></UseTemplate>
<UseTemplate Name="yyy" Node="yyy">.....<ANIM_CODE>valueNodexxx</ANIM_CODE></UseTemplate>
<UseTemplate Name="zzz" Node="zzz">.....<ANIM_CODE>valueNodexxx</ANIM_CODE></UseTemplate>
<UseTemplate Name="uuu" Node="uuu">.....<ANIM_CODE>valueNodexxx</ANIM_CODE></UseTemplate>
</Component>

Is there someway to call the value of another node?

L: variables only work on the user aircraft. I'd use the longer code because a) it works and b) the performance impact will be so small that you couldn't even measure it.

Sorry to come back to this old post by Anthony but while wanting to use it, I noticed that warnings/errors had appeared in the DEV mod Console when loading the aircraft with these codes.
By loading similar codes in the basic installation of MSFS, I found some in MSFS\Official\OneStore\fs-base-aircraft-common\Asobo\Generic\Interactions.xml.

While comparing the codes, I noticed a few differences, which I corrected and now the code no longer produces any warnings/errors during its loading.
If it can help other people or even allow Anthony to correct the XML files that include these lines.

Details: in fact it is missing the tags DefaultTemplateParameters and a closing parenthesis (7 are needed, not 6) just before the first instruction quit
Maybe it’s due to the parser of'Asobo which has been hardened since the first version of 2020

                        }
                    }

                quit

    </Template>

As I use this template for Throttle, Mixture and Prop pitch, I have also add 2 macros àt the beginning of my file and include theses macros in each template.

<Macro Name="DRAGDELTA"> 0.002 </Macro>
<Macro Name="DRAGSPEED"> 0.5 </Macro>

<Template Name = "Template_XXX">
        <DefaultTemplateParameters>
            <DRAG_DELTA>@DRAGDELTA</DRAG_DELTA>
            <DRAG_SPEED>@DRAGSPEED</DRAG_SPEED>
        </DefaultTemplateParameters>
