Examples

Here you can find a overview of examples on how to use demoinfocs-golang.

ℹ Example code may not be production ready - specifically error handling and such is done in a simplified way and should not be used in critical systems as-is.

Example	Description
heatmap	Creating a heatmap from positions where players fired shots from
nade-trajectories	Map overview with grenade trajectories
voice-capture	Capture voice data from players
entities	Using unhandled data from entities (Parser.ServerClasses())
net-messages	Parsing and handling custom net-messages
encrypted-net-messages	Parsing and handling encrypted net-messages (e.g. text chat in MM demos)
print-events	Printing kills, scores & chat messages
mocking	Using the fake package to write unit tests for your code
web-assembly	Using the library from JavaScript (browser/node) with WebAssembly
more examples	A collection of unpolished GitHub Gists based on past requests

Functions

func DemoPathFromArgs

func DemoPathFromArgs() string

DemoPathFromArgs returns the value of the -demo command line flag. Panics if an error occurs.

func GetMapRadar

func GetMapRadar(name string, crc uint32) image.Image

GetMapRadar fetches the radar image for a specific map version from `https://radar-overviews.csgo.saiko.tech/<map>/<crc>/radar.png`. Panics if any error occurs.

func RedirectStdout

func RedirectStdout(f func())

RedirectStdout redirects standard output to dev null. Panics if an error occurs.

Types

type Map

type Map struct {
	PosX  float64 `json:"pos_x,string"`
	PosY  float64 `json:"pos_y,string"`
	Scale float64 `json:"scale,string"`
}

Map represents a CS:GO map. It contains information required to translate in-game world coordinates to coordinates relative to (0, 0) on the provided map-overviews (radar images).

func GetMapMetadata

func GetMapMetadata(name string, crc uint32) Map

GetMapMetadata fetches metadata for a specific map version from `https://radar-overviews.csgo.saiko.tech/<map>/<crc>/info.json`. Panics if any error occurs.

func (Map) Translate

func (m Map) Translate(x, y float64) (float64, float64)

Translate translates in-game world-relative coordinates to (0, 0) relative coordinates.

func (Map) TranslateScale

func (m Map) TranslateScale(x, y float64) (float64, float64)

TranslateScale translates and scales in-game world-relative coordinates to (0, 0) relative coordinates. The outputs are pixel coordinates for the radar images found in the maps folder.
