This is the development repo! You most likely won't need anything in here; do not clone this. Instead, follow the instructions here to get started.
/engine: Game engine in Java/specs: Game specs in Markdown (and HTML generation)/schema: Game serialization schema (basically, an encoding of all units and events in a game)/client: Game client (visualizer and playback) in TypeScript/example-bots: A bunch of example bots for the game!
While it isn't strictly necessary, running is easier with Docker installed. If you have Windows, I'd also recommend installing Cygwin, since we have some scripts and programs that won't work with the standard Windows command prompt. (Docker is not strictly necessary, but it makes stuff easier, especially the backend.)
It's easiest to run the frontend and backend individually, in a separate terminal window for each. For instructions on how to do this, see each of their directories' readmes.
You could also run both the backend and the frontend in a single Docker container, by running docker-compose up --build. But, it's better to run them individuallly.
Windows users: Instead of ./gradlew, use gradlew for all commands.
(whenever Gradle has problems with something, run ./gradlew clean and see if it helps)
To run a game, run
./gradlew headless
The replay file will be in /matches. Use headlessX for bots that are in battlecode20-internal-test-bots. You can specify the robot code and map like this: ./gradlew headless -Pmaps=maptestsmall -PteamA=examplefuncsplayer -PteamB=examplefuncsplayer.
(Make sure you have a recent version of npm: sudo npm cache clean -f && sudo npm install -g n && sudo n stable && PATH="$PATH".)
Navigate to the client folder and run npm run install-all. You can then run
npm run watch
which will launch the client on http://localhost:8080 (if available).
You can generate javadocs as follows:
./gradlew release_docs_zip -Prelease_version=2020.0.0.0.0.1
This will create a zip file. Unzip and open the index.html file in it to view the docs. In particular, looking at the documentation for RobotController will be helpful.
To deploy these docs, get the above zip file, and unzip it. Rename the resulting folder to javadoc. Then, put it in frontend/public, suchh that there's a frontend/public/javadoc/index.html. Then run the frontend deploy process!
TODO -- these steps ought to simply be in the frontend deploy script.
When the next edition of Battlecode comes around, it will probably useful to reuse a fair amount of this codebase. Maintaining git history is nice. Use git-filter-repo for this:
pip3 install git-filter-repo
Make sure you have a recent git version (run git --version and make sure it's compatible with git-filter-repo).
As an example, the following steps were taken to port from battlehack20 to this repo:
First, create a fresh battlecode21 repo on GitHub. Clone it. Then, starting in that repo:
cd ..
git clone https://github.com/battlecode/battlehack20 battlehack20-export
cd battlehack20-export
git filter-repo --tag-rename '':'bh20-'
cd ..
cd battlecode21
git pull ../battlehack20-export —allow-unrelated-histories
(Git filter-repo can do lots of cool things; see its documenation, old examples in our repo, etc. for ideas. For example, renaming directories is possible. )
Then, port all of the codebase! Don't forget to update the files in the highest level of the repo too, such as this readme itself, and the release script.
