cygni/paintbot

An alternative to Snakebot, inspired by Bomberman's paint mode

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.

Paintbot

A game of wits between programmers where they develop bots to compete against each other in painting a canvas in their bot's color. The webpage for the game can be viewed at https://paintbot.cygni.se/

Originally based on Cygni's Snakebot

This is the server and api repository, other parts:

• Paintbot webapp
• Paintbot Java Client

Want to create your own client?

If you want to create your own client, please take a look at Client info

Getting started with intellij

• Make sure you have enabled the gradle plugin in intellij
• When creating the project, be sure to import the build.gradle file, otherwise things go wrong

To do test-runs:

• Start up the server with

> ./gradlew clean build
> ./gradlew bootRun

• Start up the webapp as described in the README. You have to change some configuration for it to go towards your local server.

const location = { origin: "http://localhost" };

• Execute the main-method of one of the clients in the clients folder
• Check the console for a link to watch the finished game, it should be in the format of

http://localhost:3000/game/{gameId}

New Release

To create a new release using a git repo as the artefactory simply ensure the build.gradle file uses a local folder to "publish" the artifacts, which should be default. Then run ./gradlew api:publish, ./gradlew client:publish and ./gradlew client-util:publish. This should build the artifacts under releases/. This folder should then be copied into the paintbot-maven-repo projects and pushed to the main branch.

Infrastructure

In order to update the infrastructure please try to use the terraform scripts in 'terraform' folder

cd terraform
AWS_PROFILE=westbos terraform apply

Most of the AWS resources are in the terraform state some still needs to be imported.

paintbot's Issues

Set default obstacles to 50

The default game settings should have number of obstacles to be 50 for a more fun and engaging environment

Might wanna change this before the tourny

Hi cygni / maintainers of paintbot!

I am currently just going through the source code in order to automate some parts of my training model for my bot and I stumble upon how you have implemented authorization. Cool I first thought, I can use it to get the token to authorize some websocket calls. But then out of curiosity, I tried the usercredentials on the live website aswell, and yeah.. Bad news. I got authorized.

I hope this can be changed before the tournament starts, because this will break the fairness of the game, if someone outside of the organizers gets hold on an auth-token.

paintbot/app/src/main/java/se/cygni/paintbot/security/AuthenticationService.java

Lines 14 to 18 in 58c3546

	Map<String, String> users = new HashMap<String, String>() {{
	put("emil", "lime");
	put("chen", "nehc");
	put("johannes", "sennahoj");
	}};

Just change the usercredentials for the live server.

Thanks for hosting this, and I hope I will get a seat.

I am currently the 1st on the waiting list (Accordingly to Josefina, A.)

Investigate / test if canIMoveInDirection(action) works as expected

Suspected that it could be buggy in some situations

Document API

At least provide JSON-examples of API

• Endpoints
• Websocket messages

Client API: Ownership of Tile

Add to the client utils for all clients that it should be easier to check if a tile is coloured and by whom.

Right now you have to loop over all characters, check their coloured positions and see if that matches a tile.

Add jitter to collision stun

Problem: Two bots may end up indefinitely stunning each other by headbutting for the same tile over and over again

Proposed solution: Add randomness to the stun duration for collisions which would allow one bot to escape an aggressor.

• Add setting for minimum stun duration
• Add setting for maximum stun duration
• Change collision stuns to be random between min and max

Create documentation / instructions for "what" to have i a client

• Define common interface
• Briefly explain what to do to create a new client
