About

Contains a Go implementation of Tic-Tac-Toe (aka "XOXO"), written for the Nakama game server. Includes pure Go implementations of a Tic-Tac-Toe Nakama module, end-to-end unit tests for the Nakama module, and a Ebitengine client that works with the Nakama module.

Showcases the end-to-end use of the github.com/ascii8/nakama-go and github.com/ascii8/nktest packages.

Overview

An overview of the primary directories in this repository:

• xoxo - Tic-Tac-Toe game logic and client in Go
• nkxoxo - a Tic-Tac-Toe Nakama module
• ebxoxo - a Ebitengine game client for Tic-Tac-Toe
• fynexoxo - a Fyne UI game client for Tic-Tac-Toe
• gioxoxo - a Gio UI game client for Tic-Tac-Toe

Command/Module entry points

• cmd/nkxoxo - the Nakama server module entry point
• cmd/nkclient - the testing client
• cmd/ebclient - the Ebitengine client entry point
• cmd/fyneclient - the Fyne UI client entry point
• cmd/gioclient - the Gio UI client entry point

Running the Unit Tests

Checkout the code and run the tests using go test from the repository root:

# get the code
$ git clone https://github.com/ascii8/xoxo-go.git && cd xoxo-go

# build/run the Nakama module with Nakama server, and run the unit tests
$ DEBUG=1 go test -v

Running the Module for use with Clients

Run the module using go test from the repository root:

# change to the repository root
$ cd /path/to/xoxo-go

# build/run the Nakama module with Nakama server
$ DEBUG=1 KEEP=2h go test -v -timeout=2h -run TestKeep

Using the Ebitengine client (Desktop)

Build and run the Ebitengine client, as a Desktop client:

# change to the repository root
$ cd /path/to/xoxo-go

# build/run the Ebitengine client
$ go build ./cmd/ebclient && ./ebclient

Using the Ebitengine client (WASM)

Build and run the Ebitengine client as a WASM module in a Web Browser:

# change to the repository root
$ cd /path/to/xoxo-go

# build wasm and run local webserver
$ go run github.com/hajimehoshi/wasmserve@latest ./cmd/ebclient

Then open http://127.0.0.1:8080 in a browser.

See: Ebitengine WASM documentation

Using the Fyne client (Desktop)

Build and run the Fyne client, as a Desktop client:

# change to the repository root
$ cd /path/to/xoxo-go

# build/run the Fyne client
$ go build ./cmd/fyneclient && ./fyneclient

Using the Fyne client (WASM)

Build and run the Fyne client, as a WASM client:

# change to the repository root
$ cd /path/to/xoxo-go

# build wasm and run local webserver
$ go run github.com/hajimehoshi/wasmserve@latest ./cmd/fyneclient

Then open http://127.0.0.1:8080 in a browser.

Using the Gio client (Desktop)

Build and run the Gio client, as a Desktop client:

# change to the repository root
$ cd /path/to/xoxo-go

# build/run the Gio client
$ go build ./cmd/gioclient && ./gioclient

Using the Gio client (WASM)

Build and run the Gio client, as a WASM client:

# change to the repository root
$ cd /path/to/xoxo-go

# build wasm and run local wgioserver
$ go run github.com/hajimehoshi/wasmserve@latest ./cmd/gioclient

Then open http://127.0.0.1:8080 in a browser.

Using the Defold client

1. Grab Defold client code, and configure:

# get the Defold client
$ git clone https://github.com/defold/game-xoxo-nakama-client.git && cd game-xoxo-nakama-client

# change game.project settings
$ perl -pi -e 's/host =.*/host = 127.0.0.1/' game.project
$ perl -pi -e 's/port =.*/port = 7352/' game.project
$ perl -pi -e 's/server_key =.*/server_key = xoxo-go_server/' game.project

2. Build and run the Defold client:

# change to path
$ cd /path/to/game-xoxo-nakama-client

# build and fix permissions
$ java -jar /opt/Defold/bob.jar --variant=debug && chmod +x ./build/x86_64-linux/dmengine

# run defold with debugging
$ DM_SERVICE_PORT=dynamic ./build/x86_64-linux/dmengine
