OpenArcade is a game engine for turn based games (or anything alike) on Ethereum.

⚠️ OA was originally a graduate capstone project. It is released to the public as free software, however due to its nature, OA is unaudited and likely under-tested.

Many features and tools are still yet to be implemented, such as

• Documentations and tutorials
• JavaScript library to interact with the game and the state channel
• Library interface improvements
• Hidden state support
• State channel as a service

• Easy and simple - You only need to implement an interface of a few functions to get going
• Library driven - Your game logic is only deployed once, saving gas
• Batteries included - It comes with many useful utils suchs as a random number generator
• Out-of-the-box state channel support - Faster and cheaper matches for your game
• Play for money (or not) - OpenArcade supports high stake competitive games
• Not just for games - any rule set can be enforced and the generic state channel can be used for whatever you wish

• See contracts/games for example games developed on OpenArcade!
• See test folder for client example code

• Copy the starter template at contracts/games/Starter.sol to contracts/games/MyGame.sol
• Change the import lines marked with TODO in MyGame.sol
• Run npm run prebuild to generate
• Write your game! Implement the functions marked with TODO
• Write some tests!
  • You can require the mock connector for your game like this in tests
  • See test/games for examples

    const Connect = artifacts.require('MyGameConnectMock')
    

  • Or you can require your game controller directly

    const Controller = artifacts.require('MyGameController')
    

• Put the tests in test folder
• Run npm test test/{test-file-for-my-game}

Coming soon

• Make your first OpenArcade game
• Common errors and pitfalls
