MSFS XML Event Trigger

[AnnaM]

Hello,

I'm stuck and cannot get an event to trigger. I have a drone with multiple engines and want the drone to go into a sort of safe mode if one engine fails, safe mode being a hover at first.

This is the code I tried and nothing happens when engine 1's RPM falls below 100 RPM:

        <!-- Drone Hover -->
        <Component ID="Drone_Hover">
        <Parameter>
        <Code>
        (A:PROP RPM:1) 100 &lt; if{ 1 (>K:FREEZE_ATTITUDE_TOGGLE) } els{ 0 (>K:FREEZE_ATTITUDE_TOGGLE) }
        </Code>
        </Parameter>
        </Component>

I then thought to link the event to the taxi light as a test, so that the hover mode gets triggered when the taxi light gets turned on:

        <!-- Drone Hover -->
        <Component ID="Drone_Hover">
        <Parameter>
        <Code>
        (A:TAXI LIGHT, bool) if{ 1 (>K:FREEZE_ATTITUDE_TOGGLE) } els{ 0 (>K:FREEZE_ATTITUDE_TOGGLE) }
        </Code>
        </Parameter>
        </Component>

No luck with that either. Am I doing something fundamentally wrong with the above code?

Any help greatly appreciated.

Thanks.

Anna

Thanks and my bad, that was just a typo here, my actual code does have that, corrected the above accordingly.

Yes thanks, all of that is correct, as in my amended post, I just messed up copy and pasting, tired eyes.

Do you have any idea why the event is not being triggered at all? Is there anything missing, should I be using some sort of Asobo XML template for all of this to work correctly?

You can use templates and it will be more convenient for you. I just do not see the full logic described in your option. It does not describe binding to animation nodes, parts, and components.

If you want a simple solution for the logic of work and dependencies of the behavior of the model, and not for animation, then it’s easier for you to make a separate device in the panel, even just in XML, and arrange everything there.

For example create a folder and file ..panel\Drone_Hover_Main\Drone_freeze.xml in the model panel

<Gauge Name="Drone_freeze" Version="1.0">
 
(A:PROP RPM:1) 100 &lt; if{ 1 (>K:FREEZE_ATTITUDE_TOGGLE) } els{ 0 (>K:FREEZE_ATTITUDE_TOGGLE) }

</Gauge>

and write it in PANEL.CFG

//--------------------------------------------------------
[VCockpit01]
size_mm=1024,768
pixel_size=1024,768
texture=$Main
background_color=0,0,255

gauge00=Drone_Hover_Main!Drone_freeze,  0,0,1024,768

And work with it. You will have the ability to easily edit, change and add parameters.

try

(>K:FREEZE_ATTITUDE_SET)

 

[EduHir]

this works in P3Dv5

        (A:IS ATTITUDE FREEZE ON,bool) 0 ==
         (A:PROP RPM:1) 100 <
        &&
        if{
          1 (>K:FREEZE_ATTITUDE_SET)
          }

        (A:IS ATTITUDE FREEZE ON,bool) 1 ==
         (A:PROP RPM:1) 100 >=
        &&
        if{
          0 (>K:FREEZE_ATTITUDE_SET)
          }

I also have added
1 (&gt;K:FREEZE_LATITUDE_LONGITUDE_SET)
or
0 (&gt;K:FREEZE_LATITUDE_LONGITUDE_SET)

Thanks for your input, for some reason it just won't work, not sure why, I'm baffled.

I have now tried to link the XML event logic to a switch with the following:

    <Template Name="Drone_Lights_Switch_Light_Template">
        <Parameters Type="Default">
            <INTERACTION_TYPE>SWITCH</INTERACTION_TYPE>
            <LIGHT_TYPE>TAXI</LIGHT_TYPE>
            <NODE_ID>Drone_Lights_Switch_Taxi_Light</NODE_ID>
            <ANIM_NAME>Drone_Lights_Switch_Taxi_Light</ANIM_NAME>
            <PART_ID>Drone_Lights_Switch_Taxi_Light</PART_ID>
        </Parameters>
        <UseTemplate Name="ASOBO_LIGHTING_Light_Template">
            <TOOLTIP_TITLE/>
            <TOOLTIPID>Taxi light switch</TOOLTIPID>
        </UseTemplate>
        <Component ID="Drone_Freeze_Position">
                <Parameter>
                    <Code>
            (L:Drone_Lights_Switch_Taxi_Light, Bool) if{ 1 (&gt;K:FREEZE_ATTITUDE_SET) } els{ 0 (&gt;K:FREEZE_ATTITUDE_SET) }       
                    </Code>
                </Parameter>
        </Component>       
    </Template>

Since the taxi light switch is a normal up or down position switch, it can have either a 1 or 0 value if my understanding is correct. So the up position should turn the FREEZE_ATTITUDE_SET on and moving the switch down should turn it off.

Unfortunately this doesn't seem to work either, I'm not sure why? I've also tried FREEZE_ATTITUDE_TOGGLE and that also doesn't work.

I can't believe this is so complicated and difficult! All I want is for the FREEZE_ATTITUDE_SET to be activated when the switch is up and deactivated when the switch is down, what am I doing wrong?

Have you got a debug file where you can check the state of some vars?

for example

      %A:IS ATTITUDE FREEZE ON,bool\t%((A:IS ATTITUDE FREEZE ON,bool))%!2.2f!\n
