Simconnect-Go

This Simconnect library is used to communicate with primary Microsoft Flight Simulator 2020 using Golang. However, given its use of the SimConnect API it should be able to communicate with other flight simulators whcih also support the SimConnect API.

This attempts to be a little more of a high-level library attempting to abstract much of the SimConnect complexity from the user.

Status

The current version is considered an early release and will therefore keep changing. Breaking changes will be avoided but may happen if required.

Currently Implemented

• Request Data on User Aircraft (SimConnect_RequestDataOnSimObjectType)
• Request Data on Object (SimConnect_RequestDataOnSimObject)
• Load Flight Plan into Users Aircraft (SimConnect_FlightPlanLoad)
• Create parked ATC AI aircraft (SimConnect_AICreateParkedATCAircraft)
• Create Non ATC AI aircraft SimConnect_AICreateNonATCAircraft()
• Set Data on Object including user (SimConnect_SetDataOnSimObject)
• Create enroute ATC Aircraft (SimConnect_AICreateEnrouteATCAircraft)
• Set Flight Plan for AI ATC Aircraft (SimConnect_AISetAircraftFlightPlan)
• Remove Objects (SimConnect_AIRemoveObject)

Install

go get -u github.com/JRascagneres/Simconnect-Go and import with import (simconnect "github.com/JRascagneres/Simconnect-Go")

Very Simple Usage

Very simple example which starts the connection, grabs the current user data and closes the connection.

package main

import (
	"fmt"

	simconnect "github.com/JRascagneres/Simconnect-Go"
)

func main() {
	instance, err := simconnect.NewSimConnect("Simconnect-Go")
	if err != nil {
		panic(err)
	}

	report, err := instance.GetReport()
	if err != nil {
		panic(err)
	}

	fmt.Printf("User Altitude: %f\n", report.Altitude)

	if err := instance.Close(); err != nil {
		panic(err)
	}
}
