Golang SimConnect for FS2020 ✈️

Golang SimConnect binding for FS2020 ✈️

This library is in developement and I have write little documentation. Please considerate this library as a testing version. It is possible non backwards compatible in the future version. But you can enjoy 🥳 and good fly !

For more information on how to use this library, please read example_test.go.

With this library you can in simulator:

• Read SimVar. (ex: Altitude, Longitude, Latitude, AP master status, Fuel, Engine...)
• Write SimVar. All the SimVar have not a possibility to be written show SimVar.Settable
• Send SimEvent for change Throttle or other
• Receive system event (ex: When the aircraft crash). Not all implemented
• Show text in the screen on the simulator

A simple example of how to use this library

package main

import (
	"fmt"
	"log"
	"strings"
	"time"

	sim "github.com/micmonay/simconnect"
)

func main() {
	sc, err := sim.NewEasySimConnect()
	if err != nil {
		panic(err)
	}
	sc.SetLoggerLevel(sim.LogInfo) // It is better if you the set before connect
	c, err := sc.Connect("MyApp")
	if err != nil {
		panic(err)
	}
	<-c // Wait connection confirmation
	cSimVar, err := sc.ConnectToSimVar(
		sim.SimVarPlaneAltitude(),
		sim.SimVarPlaneLatitude(sim.UnitDegrees), // You can force the units
		sim.SimVarPlaneLongitude(),
		sim.SimVarIndicatedAltitude(),
		sim.SimVarGeneralEngRpm(1),
		sim.SimVarAutopilotMaster(),
	)
	if err != nil {
		panic(err)
	}
	cSimStatus := sc.ConnectSysEventSim()
	//wait sim start
	for {
		if <-cSimStatus {
			break
		}
	}
	crashed := sc.ConnectSysEventCrashed()
	for {
		select {
		case result := <-cSimVar:
			for _, simVar := range result {
				var f float64
				var err error
				if strings.Contains(string(simVar.Unit), "String") {
					log.Printf("%s : %#v\n", simVar.Name, simVar.GetString())
				} else if simVar.Unit == "SIMCONNECT_DATA_LATLONALT" {
					data, _ := simVar.GetDataLatLonAlt()
					log.Printf("%s : %#v\n", simVar.Name, data)
				} else if simVar.Unit == "SIMCONNECT_DATA_XYZ" {
					data, _ := simVar.GetDataXYZ()
					log.Printf("%s : %#v\n", simVar.Name, data)
				} else if simVar.Unit == "SIMCONNECT_DATA_WAYPOINT" {
					data, _ := simVar.GetDataWaypoint()
					log.Printf("%s : %#v\n", simVar.Name, data)
				} else {
					f, err = simVar.GetFloat64()
					log.Println(simVar.Name, fmt.Sprintf("%f", f))
				}
				if err != nil {
					log.Println("return error :", err)
				}
			}

		case <-crashed:
			log.Println("Your are crashed !!")
			<-sc.Close() // Wait close confirmation
			return       // This example close after crash in the sim
		}

	}

}

simconnect's Issues

The sample can not continue when i start a new flight

I use your sample code in my program. When my first flight is over,the get var stoped.But when i back to the home page and start a new flight,the program did not continue to run.I have to close and open it again.can you help me ?

is it project is abandoned?

G1000 events doesn't work

I have problem with all g1000 events. None of them work for me. I have no problems with other events like AUTOPILOT_ON, COM_RADIO_FRACT_INC etc. But all events for G1000 like G1000_PFD_MENU_BUTTON, G1000_PFD_SOFTKEY1 does not work with cessna 172 skyhawk.

Do i have to pass any value? I tried 0,1,2,10,100. I don’t have any g1000 mod.

send event stops geting vars

Is someone is able to help me?

func main() {
    sc, err := simconnect.NewEasySimConnect()
    if err != nil {
        panic(err)
    }
    go connectToSimVars(sc)

    time.Sleep(3 * time.Second)
    event := sc.NewSimEvent(simconnect.KeyAutopilotOff)
    event.Run()

    for {
                fmt.Println(sc.IsAlive())
        time.Sleep(time.Second * 3)
    }
}

func connectToSimVars(sc *simconnect.EasySimConnect) <-chan []simconnect.SimVar {
    cSimVar, err := sc.ConnectToSimVar(
        simconnect.SimVarPlaneAltitude(),
        simconnect.SimVarAutopilotMaster(),
    )
    if err != nil {
        panic(err)
    }

    for {
        result := <-cSimVar
        fmt.Println(result)
    }
}

after i run this program i get updated sim data few time every second. After i send event to sc loop in connectToSimVars() stops. But i still get info that sc is alive (last loop)

Cannot connect multiple interfaces to SimVar

Hello,

I took the example file, but I tried to connect two interfaces to the SimVar.
simConnection.ConnectInterfaceToSimVar is always giving me an error.
