Here I was playing around with an Online Multiplayer game. The idea was multiplayer contra. Like the NES classic....with this spin: everybody would hop into the same level, play as the contra guy, and try to shoot each other.

These are the things I was wanting to try out ...

• MelonJS - a framework for browser games (two thumbs up)
• Spring 5 and Pivotal Reactor - server to handle the client connections (two more thumbs up)
• Let my 7 year old help...he's been begging me to learn...and I think he might of learned a thing or two.

I havent worked on this for a few months...so Im calling it done for now. Hopefully somebody can make use of the source code. Here are a couple videos.

Video 2: Survivor - single player mode

Contra-Client

• this folder holds the game client
• runs with node builds with grunt
• to run ... cd into the contra-client directory
  • npm i
  • grunt serve
• the game will now be available at http://localhost:3000

Contra-Server

• this folder holds the game server
• runs with java builds with maven
• to run ... cd into the contra-service directory
  • mvn package
  • sudo mvn spring-boot:run
• the server will now be available at localhost:80
• to verify the server is working ... http://localhost/game/sse-flow-test

I hosted this thing on a free AWS box. The performance was pretty solid...got several players playing together and it didnt lag...the bullets hit well.
