Brain / Out

Source code for Brain / Out, the game.

How To Build From Source

OpenJDK 11 is required.

First, clone this repo.

Use Gradle Wrapper: ./gradlew <command> on mac/linux, or gradlew.bat <command> on windows

To obtain project, use ./gradlew idea to generate IntelliJ IDEA project. Once project is generated, open brainout.ipr within IntelliJ IDEA IDE.

Do NOT let the IDE "load gradle project", just stick with ipr.

Make sure you build your data, call ./gradlew make_data

Then,

1. ./gradlew desktop:dist to build desktop client
2. ./gradlew steam:dist to build steam client
3. ./gradlew server:dist to build server

For either of those to work, Game Assets has to be built.

Look at the troubleshooting document, it includes several common issues and how to fix them.

Dependencies

Setup SDK for IntelliJ IDEA:

1. Click Project Structure
2. Select SDKs
3. Click "+", Download JDK
4. Select version 11
5. Download it and rename to "1.8"
6. Run ./gradlew idea again

On first install, or after any assets changed, make sure to call ./gradlew make_data

How to build Game Assets

See this readme for how to change Game Assets.

To build them, call ./gradlew make_data

NOTE: the client digitally verifies the built data! So by default, the client won't be able to start up with locally built data, since the private key is not present in this repository. Pass --unsafe command line argument to the client so it would ignore non-signed packages. Offline Unsafe IDEA configurations already do this.

Offline build

By default, both the client and the server are trying to participate into the Alpha game network. Since no keys are present in this repository, for locally run builds please pass --offline command line argument both to the server and the client. Offline IDEA configurations already do this.

Run configurations

Server Lobby – server hosting "Main Menu". Offline version is offline, Alpha version participates in the Alpha network.

Server – server hosting active game phase. Offline version is offline, Alpha version participates in the Alpha network.

Server Editor – server hosting old non-steam editor. Offline version is offline, Alpha version participates in the Alpha network. Important to note that client looks for Home User folder brainout-maps by default to upload any map, use BRAINOUT_MAPS environment variable to point client to <this repo>/bin/server/maps.

Desktop Local Offline Unsafe – a client that tries to connect to server on localhost. It uses --connect brainout://bG9jYWxob3N0OzM2NTU1OzM2NTU2OzM2NTU3 argument which is bas64-encoded localhost;36555;36556;36557

You might also see there's Desktop Local 2 * configurations, these are copies under different user, e.g., you can launch those two in parallel and run two instances of the game on same PC.

Desktop Alpha – a client that tries to participate Alpha network.

Testing

The project has a CI system in place: on every new commit, it builds a new version of client/server and deploys it automatically. There are two environments available:

• main, which is built on every master commit
• test, which is built on every pull request. A new pull request wipes out the previous one, as it is intended to verify the correctness of the pull request.
• dev, which is build on every dev_* branch commit. Contributors with collaboration permissions could push there directly and skip PR requirements to check things quickly.

The clients of those builds are deployed on Dropbox, to get invited there, please join the Dev Support telegram channel below and ask for invite link.
