accshm

Go implementation for reading Assetto Corsa Competizione Shared Memory Pages

This module obviously only works on Windows, as ACC only runs on Windows as well.

Basic Usage

Import the module like this:

import "github.com/Dekadee/accshm"

Read the memory page like this:

physics := new(accshm.ACCPhysics)

// Reading will fail, if the game has not been started at least once
err := ReadPhysics(physics)
if err != nil {
    // Handle potential errors
}

if prevPacketID != physics.PacketId {
    // Do something with the new data
}

// Analog for Graphics and Static memory page

At the moment the function creates a buffer everytime it is called. This may be very inefficient, but realistically reading the memory pages is very fast and has almost no noticeable performance impact.

Eventing

Instead of reading the memory pages yourself, you can subscribe to events like new lap times, sector times etc. You can add handlers to events like laptime updates etc.

eventPublisher := accshm.NewEventPublisher()

err := eventPublisher.AddLaptimeSubscription("printer", func(update LapTimeUpdate) {
    fmt.Printf("Last Time: %q", update.LastTime)
})

// Starts polling the shared memory every x seconds
eventPublisher.Start(1)

...

// Stop polling the pages
eventPublisher.Stop()
