• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Nav DME trigger

Hello all. First post for me. I'm just beginning creating missions and I'm finding out there is a mountain of things to learn. Having a lot of fun so far.
My first mission is an IFR flight from Tulsa to St. Louis. Doing pretty good so far but I'm stumped on one item. How do you set a trigger to fire a dialog action when the aircraft is x DME miles from a VOR?
This is what I tried but its not working:
<SimMission.PropertyTrigger InstanceId="{0FF8BDCC-9D1A-44DD-B106-740774C0ED55}">
<Descr>Test nav dme trigger</Descr>
<Condition>
<And>
<LessOrEqual>
<LHS>
<Constant>
<Text>NAV DME:</Text>
</Constant>
</LHS>
<RHS>
<Constant>
<Double>20.000</Double>
</Constant>
</RHS>
</LessOrEqual>
</And>
</Condition>
<Actions>
<ObjectReference id="Dia Track SGF outbound 039" InstanceId="{B85C24F8-A7B1-430F-9B99-E5A86DA94749}">
</ObjectReference>
</Actions>

Thanks in advance.

I'M not sure if that is possible. Did you chose the constant "NAV DME:" from a dropdown list?

I'd say the best thing would be to use a proyimity trigger. If a pilot is flying on a flightplan this is pretty easy to setup, because you just have to place a huge "Wall" area (very wide, very high, but only some several feet long) at the distance when the action should be triggered.
If the pilot may approach from different angles you rather want to use a huge cubicle area around the DME. That would mean that the trigger won't probably fire exactly at DME20 or so because the area round the DME wouldn't be a cone but a cube.

Anyway, a prox trigger seems to be the way to go.
 
No, not from a drop down list but rather from a list of sim variables. I thought of the prox trig but I thought there might be a better way. Thanks for the reply.
I like this forum. I've been reading along as I go and the questions/answers are very useful. Keep it up.

Thanks,

Jerry
