只要你能用C++和JavaScript编程，你就可以创建EOSIO应用
Block.one做了元素战争（Elemental Battles）这个课程游戏简化了EOSIO新手的学习曲线，从而鼓励新一代的区块链开发者投身该技术。这是一个免费的在线课程，课程共设8节，任何有C++和JavaScript基础的人都可以编写一个设置于魔幻世界的游戏，玩家可以驯服三个元素——木元素、水元素和火元素。游戏中，玩家需要利用EOSIO代码库的基本区块建立相同的游戏并且学习如何在EOSIO平台上建立区块链应用。
怎么玩
游戏中，每个动作的目的就是挑出一张卡片“打败”电脑挑选的卡片。每张卡片对应一个元素和相应的分值。沿袭区块链应用的本质，所有的教学和游戏结果都会被记录在区块链上。
课程设置
每堂课都是以分屏的形式展现的，左边是解释，右边是对应代码。其中涉及的关键话题包括：
- 怎么建立开发环境
- 怎么建立EOSIO智能合约
- 怎么通过网页前端进入区块链和智能合约
你能学到什么
最终，等上完这八节课，你可以建立自己功能完善的元素战争游戏版本，之后你就可以开始建立自己的EOSIO DAPP了。不管玩家在游戏中输赢如何，但是他们完成了课程、学习了区块链这个革命性的技术、反过来还开发了EOSIO软件，这个过程就让他们获益匪浅。
最新更新
课程在十月上线，现在建立过程已经由原来的eosiocpp改为eosio.cdt。现在它还支持以下版本：
- Docker 版本17.06 及以上
- EOSIO 版本1.6.0
- Eosio.cdt 版本1.5.0
- EOSJS 版本20.0.0-beta 3

As long as you can code in C++ and JavaScript, you can learn to build EOSIO apps
Elemental Battles is a tutorial-game which Block.one has created to inspire and on-board a new generation of blockchain developers by simplifying the learning curve for EOSIO beginners. It is a free, eight-lesson online tutorial for anyone with basic knowledge of C++ and JavaScript, building a game set in a fantasy world where players can harness the power of three elements — Wood, Water and Fire. Build the same and learn to create blockchain apps on the EOSIO platform by utilizing basic building blocks of the EOSIO codebase.
How to play the game
In the game, the aim of each move is to select a card that ‘beats’ the card selected by a computer-powered opponent. Each card corresponds to an element and has its own point value. True to the nature of a blockchain app, all tutorial and game results will be recorded on the blockchain.
How to navigate the tutorial
Each lesson is presented in split-screen format, with explanations on the left panel and codes reflected on the right. Key topics covered include:
- How to set up a development environment
- How to develop an EOSIO smart contract
- How to access the blockchain and smart contract via a web-based front-end
What you gain from the game-tutorial
Ultimately, by completing the eight lessons, you can build your own fully-functioning version of the Elemental Battles game — even before you get started with building your own EOSIO DAPP. Win or lose, players gain from working through the tutorials, learning about the revolutionary technology that is blockchain, and in turn, developing on the EOSIO software.
Latest updates
Since its launch in October, the tutorial has been updated to use eosio.cdt instead of eosiocpp for the building process. It has also been updated to support the following versions:
- Docker version 17.06 or newer
- EOSIO version 1.6.0
- Eosio.cdt version 1.5.0
- EOSJS version 20.0.0-beta 3
