GoonServer

The server component for GoonScape, handling multiplayer synchronization and chat.

Features

• Tick-based game state synchronization
• Player movement validation
• Global chat system
• Client connection management
• Protobuf-based network protocol

Prerequisites

• Go 1.23 or higher
• Protocol Buffers compiler (protoc)

Installation

1. Clone the repository:

git clone https://gitea.boner.be/bdnugget/goonserver.git
cd goonserver

2. Install dependencies:

go mod tidy

3. Build and run:

go run main.go

Configuration

Server settings can be modified in main.go:

const (
    port     = ":6969"               // Port to listen on
    tickRate = 600 * time.Millisecond // Server tick rate
)

Protocol

The server uses Protocol Buffers for client-server communication. The protocol is defined in actions/actions.proto:

• Action: Player actions (movement, chat)
• ActionBatch: Grouped actions from a player
• ServerMessage: Game state updates to clients
• PlayerState: Individual player state
• ChatMessage: Player chat messages

Development

After modifying the protocol (actions.proto), regenerate the Go code:

protoc --go_out=. actions/actions.proto

Deployment

The server is designed to run on a single instance. For production deployment:

1. Build the binary:

go build -o goonserver

2. Run with logging:

./goonserver > server.log 2>&1 &
