BeamNGMockOG

Utility to both record (with the caveat that it doesn't record yet) and replay binary data relating to the Outgauge struct of beamng.

This will help me develop some stuff I'm doing for ESDI and my peripherals without having to be playing the game while doing it (fans are noisy).

Installation

go install github.com/ESilva15/BeamNGMockOg@latest

Usage

To start replaying: telemetrymockserver beamng replay [--loop] -a 127.0.0.1 -p 4443 -i sunburstManual.bin

loop allows the replay functionality to keep replaying the same data file

To start recording: BeamNGMockOg beamng record -a 127.0.0.1 -p 4443 -o sunburstDCT.bin

Development

Use tcpdump to listen to the socket and check if data is coming through: tcpdump -i any udp port <port> -X

TODO:

Create the auto completion file and add it to $FPATH
Create a shortcut so we don't have to type out telemetrymockserver everytime

Benchmark

Run with: go test ./mockserver -bench=BenchmarkReplayAsync -benchmem -benchtime=1x -memprofile=mem.pprof

Analyze the output with: go tool pprof -sample_index=alloc_objects mem.pprof -> top

ignore=net will ignore the net package for example
focus=mockserver will show only the results from this code we are testing or go tool pprof -http=:8080 mem.pprof
