Configuration

Game server: plugins/GrayCorePaper/config.yml

spawn:                       # where /spawn and teleportOnJoin send players
  world: "world"
  x: 0.5
  y: 64
  z: 0.5
  yaw: 0
  pitch: 0
teleportOnJoin: true         # send players to the spawn when they join

database:
  endpoint: "jdbc:postgresql://localhost:5432/postgres"
  username: "graycore"
  password: "123"
  schema: "public"
  enableLiquibase: false     # create and migrate the schema at startup (one server is enough)
  poolName: "GrayCorePool"
  maxPoolSize: 10            # connection pool (HikariCP)
  minIdle: 10
  maxLifetime: 1800000       # ms
  keepAliveTime: 0           # ms
  timeout: 5000              # ms

redis:
  host: "localhost"
  port: 6379
  username:
  password: 123
  timeout: 10                # seconds

actuator:                    # health and metrics over HTTP
  enabled: false
  port: 8080

/gcadmin reload reads it again.

Proxy: plugins/graycore-velocity/config.yml

database:                    # same settings as on the game servers
  endpoint: jdbc:postgresql://localhost:5432/postgres
  username: graycore
  password: 123
  schema: public
  createStructure: false     # create and migrate the schema at startup
  poolName: GrayCorePool
  maxPoolSize: 10
  minIdle: 10
  maxLifetime: 1800000
  keepAliveTime: 0
  timeout: 5000

actuator:
  enabled: false
  port: 8080

Modules: plugins/GrayCorePaper/modules/<id>/config.yml

Each module has its enabled switch and its own settings, see Modules.

server-service: application.yaml

Setting	Default	What it is
server.port	8080	HTTP: health and metrics (/actuator/health, /actuator/metrics).
spring.grpc.server.port	9090	gRPC, where game servers and proxies connect.
server-service.api-key	${GRPC_API_KEY}	The key every client must present.
server-service.server-ttl-ms	3000	A game server silent for longer than this is removed (heartbeats come every 500 ms).

Texts

Every player-facing text is in locale/en.yml, next to each configuration, in MiniMessage. Edit them there; a key you remove falls back to the default.
