This is the source code for the RPG game from the 2023 edition of justCTF.
There are two challenges in this game:
- Trial of Data - analyze the compiled game data in order to complete 5 challenges
- Trial of Bugs - two challenges that require the player to find bugs with the game
In order to develop this game, you need the following software:
In order to build the game for the first time you need to do these steps:
- build Spright and edit the local_config.json file with the path to the executable (the key in the JSON is
sprightBin) - run
yarn installandnpx tsc node build/tools/script_builder/builder.js && node build/tools/spritesheet_builder/builder.js && node build/tools/map_builder/builder.js
Now you can start the game server by running node build/server/server.js and the client server using npx webpack serve. The game can be played by navigating to http://localhost:8080/
When you make changes to the game files, you need to manually run the *_builder scripts. As such, I usually launch the server by running a command like the following:
node build/tools/script_builder/builder.js && node build/tools/spritesheet_builder/builder.js && node build/tools/map_builder/builder.js && node build/server/server.js
You can create a deployment package by running ./tools/deploy/create_packages.sh.
In order to enable game saving/persistence, you need to start a local postgres instance and edit local_config.json appropriately.
The easiest way to start postgres for this game is to build a deployment package and run docker compose up db from the build/packages directory. Afterwards you need to set noDatabase to false in local_config.json.
Please note that in order to run the server with a database the session server has to be running as well. It needs to be started before the game server by running node build/server/player_session_server.js. Afterwards the game server can be started as normal.
