CSGO Demo Renderer

A CSGO Demo renderer using GraphQL. It takes a CSGO Demo in binary format and encodes it into JSON. It only respects the attributes, which the user specifies in the query, therefore not over or underfetching any data resulting in a bloated JSON.

How to run

Build

If you want to build the app, clone the repository and run

go run cmd/main.go --query ./examples/prod.graphql --demo examples/test.dem

For building the webserver run

go build cmd/webserver.go --query ./examples/prod.graphql --port 8080

It builds a binary called main or webserver.

Execute the application

Run using

csgodemo --query query.query --demo demo.dem

where the query.query is a file containing a graphQL query.

{
  demo(freq: 0.2) {
    header {
      mapName
    }
    ticks {
      participants {
        entityId
      }
    }
  }
}

Where freq is the recording FPS.

It creates a File named out.json containing all data.

ls
+ out.json

For exploring purposes, you can use the interactive Graphiql tool available at

https://larskoelpin.github.io/csgo-demo-graphql/

Run as Webserver

There is also

csgodemo --query query.query --port 8080

This hosts a simple HTTP-Server listening on Port 8080. It accepts any request containing a CS:GO Binary. Please do not use this for public facing apps!

Considerations

If you want to send the json over the wire, try deflateing it using gzip

creates a File named out.json

gzip out.json //out.json.gz

inflate using

gzip -d out.json.gz
