Nacos 架构 < 76 Eureka 和 Nacos 相比较 Zookeeper 而言，已经改善很多，这两个产品有针对服务注册与发现的 客户端，也有基于 SpringCloud 体系的 starter，帮助用户以非常低的成本无感知的做到服务注册 与发现。同时还暴露标准的 HTTP 接口，支持多语言和跨平台访问。Eureka 和 Nacos 都提供官方 的控制台来查询服务注册情况。不过随着 solar-framework-starter-service ${solar.version} 网关 com.zhangmen solar-framework-starter-zuul 通过多注册和聚合订阅平滑迁移到 Nacos 的架构图如下：  通过引入 edas-sc-migration-starter 使得 Spring Cloud 应用支持多注册，这样确保原有系统 的应用可以调用 注册到 Nacos 中的服务。  通过引入 edas-sc-migration-starter 并配置 RibbonClients Configuration 支持聚合订阅，使 得迁移到 Nacos

In this tutorial we’ll create a basic template you can use to make your own top-down games using Phaser, an awesome HTML5 game framework. This template will be expanded in further tutorials to add for your game using Tiled and load them using Phaser. 2-Learn how to create a basic top-down game starter. Concepts covered -Setting the game size in pixels -Tiled basic usage -Tile layers and object this: Before we move any further, I’d like to make it clear that this will work with the game template we are building in this tutorial, it is not a default Phaser functionality. Phaser only provides

basic idea of what is done in the Touhou screenshot. It is really that simple, and an excellent starter point for anyone that wants to build a game with this concept in mind. Zenva Academy – Online
