MINECRAFT 快照 20W21A
一个 Minecraft Java 版快照
作者：Adrian Östergård
发布日期：2020/05/20
在这次快照，我们添加了自定义世界设定和自定义维度的支持。这是一个用来收集反馈的早期特性——要留意这个特性是实验性的且不被优先维护的。任何自定义世界设定会随着快照的更新而变化，同时使用了自定义设定的世界会被明确地在世界列表标记为实验性。
20W21A 新增特性
- 添加了将一个红石线在十字和点状间切换的能力
- 添加了导入/导出世界设定功能
- 添加了一个新命令行选项 disableMultiplayer，当使用时多人游戏按钮会被禁用
- 添加了一个新命令行选项 disableChat，当时用时收发在线消息功能会被禁用
红石切换
- 对一个单独的红石右键会使其在十字状和点状形态间切换
- 点状的红石不能充能其周围的方块
20W21A 内容改动
- 猪灵 (Piglin) 在欣赏金子时不再走来走去
- 当你伤害一个正在欣赏金锭的猪灵时，那个金锭会消失
- 提高了玄武岩三角洲 (Basalt Deltas) 的矿石生成概率以抵消这个生物群系减少的下界岩数量
- 睡莲现在被算作垃圾钓鱼战利品而不是宝藏
- Mojang Studios 和 Minecraft 的新版 logo
- 临时移除了超平坦预设中的结构设定（临时方案：用导入/导出设定功能）
20W21A 技术性变动
- 为
spreadplayers 命令添加了控制高度的能力
- 添加了自定义世界和自定义维度
命令
SPREADPLAYERS
添加了一个可选参数来指定最大高度。
新语法：spreadplayers <center> <spreadDistance> <maxRange> [under <maxHeight>] <respectTeams> <targets>
LOCATE
自定义世界
- 添加了对自定义世界的实验性支持
- 编辑世界屏幕现在有了一个选项来导出世界设定为一个 JSON 文件
- 创建世界的过程中你可以导入之前导出的世界设定
- 暴露了一堆新参数，但被标记为实验性，这意味着你可以随便试试，但不保证它们一直有效（哪怕是下一个快照！）
- 超平坦世界预设字符串失去了结构设定（它们现在被储存为一个所有世界通用的格式），我们很快会以某种形式恢复这个功能
- 自选世界不再能够通过 server.properties 创建；超平坦世界设定有了一点变化；更好的服务器自定义世界创建功能即将到来
