如何让玩家从区块链元宇宙“公共领域”进入到一个元宇宙游戏系统开发之中，再从一个游戏进入到另一个游戏，这期间保证玩家的体验连贯，需要计算机图形学技术和物理硬件算力、储存技术的保证，这个也是限制这个阶段“元宇宙”开发发展的重要的因素。随着各方大厂开始布局“元宇宙”游戏，“元宇宙”这个概念也开始映入玩家的眼中。说到“元宇宙”，大家想到的可能是《头号玩家》这一部电影，电影中玩家穿梭于现实世界和“绿洲”之中，我首次看的时候产生了很多疑问，比如——“这个游戏那么大，游戏服务器到底是存在什么地方？”“为什么大BOSS的游戏公司明明创造了这个游戏，但却没有这个游戏的掌控权？”“游戏中那么多琳琅满目的游戏道具，游戏策划是怎么把这么多不同类型的道具塞在一个游戏里面的？”直到后来我学习了区块链等相关技术才搞懂，下面我将围绕上面相关问题，一步步地去说明“元宇宙”游戏的发展阶段和相关实现方法。首先“元宇宙”游戏的诞生不是一蹴而就的，目前“元宇宙”开发所需要的相关技术还在起步阶段，很多概念和方法甚至还没到理论可行的地步，根据我的学习和总结，我将元宇宙的发展过程总结为下面四个阶段：First stage: UCG platform game (single game plus user-made content).The game at this stage realizes the diversity of game forms. For example, Roblox and LayaMe are the products of this stage. The "meta universe" game at this stage meets the needs of players for entertainment and social interaction, and the open editor of the game allows players to make many kinds of game content for community play.Although there are a lot of game content, the quality average line and the masterpiece of 3A Studio, even some large-scale mobile games, can't be compared. There is a gap between user-made content and large-scale commercial projects. Secondly, there is no independent economic system for the game. Players can't carry out complex economic activities here. The currency in the game is only limited to the internal use of the game. The game manufacturer has the right to live and kill the game's economic system. NFT games also belong to this stage of content, but the playability of NFT games is not high. NFT games are mainly used as financial products and encryption art, and the game attributes are limited.第二个阶段：多游戏互联。这个阶段的游戏实现了游戏内容连通性、游戏资源自给性、游戏资产不灭性。如果单一游戏靠玩家自制内容没办法实现足质足量的游戏，那么将多个游戏连通在一起怎么样？多游戏连通则是这个阶段大的特征，“元宇宙”重要的特征是具有“文明性”，让一个虚拟的世界具备现实文明特征，重要的一步就是具有经济的流动性。How to realize this liquidity? First of all, the currency of one game can be used in another game, and then the issuance of currency will not be controlled by individual individuals and organizations. Although the resources of the current game are produced by code, the planners of the game company are behind the control. They have the right to live and kill in the resource allocation of the game, Minor adjustment of some parameters of a version may cause the collapse of the game economy system.The resource output required for the development of the "meta universe" system is not determined by a single individual, but by some neutral and objective rules. In order to realize the following three points: "money can be used in multiple games", "the issuance of money will not be controlled by individual individuals and organizations", and "the output of game resources is controlled by objective parameters and will not be controlled by individual individuals", blockchain and other related technologies need to be used假如我是某个游戏大厂，我要做这个阶段的“元宇宙”游戏，只要将游戏中的某种资源或货币换成区块链货币，那要如何引入区块链系统？“智能合约”的运用就是为了实现资源分配的客观中立性，当多个游戏都是使用同一条链，怎么分配这些资源就成了问题，比如简单的模型，我们使用单位时间内的“总玩家数量”和“总玩家的游戏时长”作为智能合约判断的节点，根据这个发放相应数量的货币给对应的游戏，对应的游戏又根据别的“智能合约”把从链上获得的货币根据玩家贡献的资源发放给玩家。当然对比起一条链给多个游戏使用，让一个游戏的资源作为主链、让其他游戏的资源作为侧链也可以实现类似的效果。比起传统的把数据存在单一服务器，使用区块链还有两个好处是前者不具有的，当游戏关服后，将“联盟链”改成“公链”可以让忠实的玩家成为全节点保存这些记录，就算关服了游戏内的虚拟道具所有权还可以继续通过区块链进行玩家间的交易，脱离游戏本身也是可以进行经济交易的，甚至一些别的游戏也可以通过这些记录把这个游戏的道具复现在自己的游戏里面，虽然这个阶段的区块链大都以“联盟链”而存在，但让“联盟链”成为“公链”仍是未来趋势和下一阶段重要的条件之一，。What players can exchange depends on the manufacturer. At the same time, what manufacturers can exchange to players is not only virtual props, but also in-game cultivation resources. Manufacturers should not only consider how to let the blockchain currency flow into their own games, but also how to let the blockchain currency flow into the manufacturer's account from the player's account. At the same time, this model does not conflict with the traditional profit model of the manufacturer. The two systems can be put into the same game at the same time. I can exchange real money for virtual props, and I can also exchange blockchain money for virtual props. It is not difficult to access the system. Even the old games that have been released can create some props to access the blockchain system, Moreover, whether the newly accessed game can make money from this system depends on the design of the manufacturer's content. After the access, the problem of depreciation and appreciation of props and inflation can be completely handed over to the player to trade and circulate, and the developer can concentrate on the research and development.In fact, cultivation resources can also be used in blockchain. Using NFT technology, you can add a lot of playing methods, and even realize some functions previously proposed by players. If it is an SLG game, you can put the ownership of the mine in it. Through the smart contract, once the player has captured the mine, the smart contract will use the current status as the node to determine the ownership of the change. Similarly, the ownership of the MMOARPG copy or the capture record of the copy can also remain in the blockchain. For some leisure games, the property can also be placed in the blockchain.
