Move a non ATC aircraft

[Arsaphes]

Hi everyone,

Sorry to ask that, I'm discovering all that simconnect stuff...

So far, I managed to create an aircraft using the AICreateNonATCAircraft function. I can see the aircraft on the ground, everything is fine. Now, I'd like to move that aircraft. I wanted to use the SetDataOnSimObject function, but I definitely don't understand how to use it. How to get the definition ID and the object ID? Could someone provide me an example please?

Thanks a lot for your help!

Hi! Thanks for reaching out!

Assuming that function works similar to AICreateEnrouteATCAircraft, subscribing to the system event ObjectAdded will give you the object ID of the spawned aircraft. I haven’t tested this myself though.

EDIT: like this

enum MY_EVENT_ID {
    OBJECT_ADDED_EVENT,
    OBJECT_REMOVED_EVENT,
};

// Clean up previous subscriptions, if any 
handle.unsubscribeFromSystemEvent(MY_EVENT_ID.OBJECT_ADDED_EVENT)
handle.unsubscribeFromSystemEvent(MY_EVENT_ID.OBJECT_REMOVED_EVENT)

handle.subscribeToSystemEvent(MY_EVENT_ID.OBJECT_ADDED_EVENT, "ObjectAdded")
handle.subscribeToSystemEvent(MY_EVENT_ID.OBJECT_REMOVED_EVENT , "ObjectRemoved")

handle.on("eventAddRemove", (e) => {
    switch(e.clientEventId) {
        case MY_EVENT_ID.OBJECT_ADDED_EVENT: 
            console.log(`${SimObjectType[e.type]} was added with simobject ID ${e.data}`) 
        break;
        case MY_EVENT_ID.OBJECT_REMOVED_EVENT: 
            console.log(`${SimObjectType[e.type]} with ID ${e.data} was removed`) 
        break;
    }
});

const spawnPosition = new InitPosition()
spawnPosition.latitude = 60.19669814227938
spawnPosition.longitude = 11.094849220919981
spawnPosition.onGround = true

handle.aICreateNonATCAircraft("DA62 Asobo", "LN-ABC", spawnPosition, 1234)

Regarding the data definition ID this must be created in the same way you would do when requesting or setting simvars on the user's aircraft. The data definition is used to describe the contents of the data chunk you will be sending. The definition should be created once and reused whenever you need to send the same set of simvars.

Example:

// Define the data structure (done once)
const PLANE_POSITION_DEFINITION_ID = 123;
handle.addToDataDefinition(PLANE_POSITION_DEFINITION_ID, 'Plane Latitude', 'degrees', SimConnectDataType.FLOAT64);
handle.addToDataDefinition(PLANE_POSITION_DEFINITION_ID, 'Plane Longitude', 'degrees', SimConnectDataType.FLOAT64);

// Prepare the data blob to send
const dataChunk = new RawBuffer(1)
dataChunk.writeFloat64(60.1968)
dataChunk.writeFloat64(11.0949)

// Send the updated position
handle.setDataOnSimObject(PLANE_POSITION_DEFINITION_ID, spawnedAircraftId, {
    buffer: dataChunk,
    arrayCount: 0,
    tagged: false,
})

I managed to get the created aircraft ID with the following code:

handle.on('assignedObjectID', function (recvAssignedObjectID) {
    console.log("->", recvAssignedObjectID.objectID);
});

and then use your example above to update the aircraft position.

Thanks a lot for your help!

Ahh, thanks for sharing - that is probably the intended way to retrieve it. I see recvAssignedObjectID also includes the request ID you pass to aICreateNonATCAircraft, and recvEventAddRemove lacks this information.
