• 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.

FSX Engine Fire SimConnect variable

I am trying the SimConnect ENG FIRE:index simvar without success. I have done everything but when I trigger with this:

simConnect.RequestDataOnSimObjectType(DATA_REQUESTS.REQUEST_FIRE, DEFINITIONS.EngineFire, 0, SIMCONNECT_SIMOBJECT_TYPE.USER);​

I get a response from the simulator in my data request indicating 'false' on this structure:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
struct EngineFire
{
public bool Engine1Fire;
}
​
The data request was registered as follows:

simConnect.AddToDataDefinition(DEFINITIONS.EngineFire, SimVars.ENGINE_ON_FIRE_1, SimUnits.BOOLEAN, SIMCONNECT_DATATYPE.INT32, 0.0f, SimConnect.SIMCONNECT_UNUSED);
simConnect.RegisterDataDefineStruct<EngineFire>(DEFINITIONS.EngineFire);​

what am I doing wrong? I get no exception, just that it is false and don't see any fire being set on the engine.
​
 
Great, that was it! how could I have missed it! I got it working now but it is a pity that there is no Engine Fire notification event
 
Something very odd is happening. I am trying it with the default C172 (single engine) and when my definition structure has 2 bool (for a twin) triggering fire on Engine 1 does not work. If I trigger on Engine 2 then it the single engine goes on fire but it won't get extinguished until I toggle it off with engine 1. It seems it is mixed up as to what is engine 1 or 2 even though it is a single engine plane.
