go-csgsi

A library written in Go for Counter-Strike: Global Offensive's Game State Integration.

About

The go-csgsi package listens on a specified port waiting for a HTTP POST request by CS:GO. Once a request is received, it is parsed and ready for the end user.

This information can be continuously retrieved and analyzed using a Channel. (See usage & example)

Installation

Via Go:

$ go get -u github.com/dank/go-csgsi

Usage

To initialize the library:

// size int - Size of the channel
game := csgsi.New(10)

To receive updates, read from the channel provided: game.Channel:

// Example 1 - Looping (blocking)
for state := range game.Channel {
	fmt.Println(state.Player.SomeData)
}
// End

// Example 2 - Wait for a state object to come in (blocking)
state := <-game.Channel
fmt.Println(state.Player.SomeData)
// End

// Example 3 - User creates a func and runs it in a Go routine (thread) (non-blocking)
go func() {
    for state := range game.Channel {
		fmt.Println(state.Player.SomeData)
	}
}()
// My non-blocked code can go here!!!
// End

To start listening to an address:

// address string - TCP address to listen on
game.Listen(":3000") // localhost:3000
game.Listen("8.8.4.4:3000") // 8.8.4.4:3000

        .Added
            .State; State
        .Auth
            .Token; string

Example

Prints weapon stats (name, ammo) when weapon is active:

func main()  {
	game := csgsi.New(0)

    go func() {
		for state := range game.Channel {
			for weapon := range state.Player.Weapons {
				weapon := state.Player.Weapons[weapon]
				if(weapon.State == "active") {
					fmt.Printf("%s %d/%d\n", weapon.Name, weapon.Ammo_clip, weapon.Ammo_reserve) // => weapon_glock 20/120
				}
			}
		}
	}()

	game.Listen(":3000")
}

You'll need to create a gamestate_integration_*.cfg file under csgo/cfg in your CS:GO installation directory. For example, gamestate_integration_consolesample.cfg:

"Console Sample v.1"
{
    "uri" "http://127.0.0.1:3000"
    "timeout" "5.0"
    "buffer"  "0.1"
    "throttle" "0.5"
    "heartbeat" "60.0"
    "auth"
    {
        "token" "SuperSecretPassword"
    }
    "data"
    {
        "provider"            "1"
        "map"                 "1"
        "round"               "1"
        "player_id"           "1"
        "player_state"        "1"
        "player_weapons"      "1"
        "player_match_stats"  "1"
    }
}
