gameserver-rs

This is a sample implementation of a game matchmaking system and real-time game server, written in Rust.

Matchmaking

The matching system uses Open Match and implements the following components:

• Game Frontend implementation
  • frontend
• Director implementation
  • director
• Match Function
  • mmf
  • It matches players with a fixed number of players in the order they came in and assigns a game server running on the Agones

Real-time game server

The implementation in gameserver is a real-time game server for multiplayer running on Agones.

How to run on minikube

# Install Agones on your Kubernetes cluster.
# https://agones.dev/site/docs/installation/
# Install OpenMatch on your Kubernetes cluster.
# https://open-match.dev/site/docs/installation/

$ make
$ make minikube_cache_del
$ make minikube_cache_add
$ cd k8s

# Start gameserver and match maker

## Allocate one game server pod for one match
$ kustomize build gs-single-alloc | kubectl apply -f -

## Allocate one game server pod for multiple matches
## The matchmaker director acts as a gameserver sidecar, allocating itself to multiple matches.
## Workaround until this issue is supported: https://github.com/googleforgames/agones/issues/1197
## gs-multi-alloc cannot be started at the same time as gs-single-alloc, so please delete it once
$ kustomize build gs-single-alloc | kubectl delete -f -
$ kustomize build gs-multi-alloc | kubectl apply -f -

# run example
$ cd examples
$ cargo build --bin match-and-join
$ MM_SERVER_ADDR=$(minikube ip):$(kubectl get svc frontend -o jsonpath='{.spec.ports[0].nodePort}') ./target/debug/match-and-join
