MINECRAFT 快照 20W18A
一个 Minecraft Java 版快照
作者：Adrian Östergård
发布日期：2020/04/29
在这次快照我们对红石线做了些改动，并处决了一堆碧油鸡。
20W18A 内容改动
红石线
红石线的方块状态、渲染和行为更加一致。红石会在任何表现为相连的方向上为方块供能，反之如果没有表现为相连则不会供能。
- 单独的红石线现在表现为一个十字
- 从方块下方转向到方块上方的红石线会在相连的一面为方块供能。例如，位于引线上方的栅栏门会被充能
- 向上延伸到非导体方块的红石线之前只在外观上有转向效果。现在这个转向也应用到它的行为上
- 一条越过方块的红石线现在总是会对那个方块充能。这在红石线的信号强度仅为 1 时最能体现
1.15.2 与快照 20w18a 的对比
20W18A 技术性变动
- 添加了
enable-status 选项到 server.properties 文件中，当设定为 false 时会阻止服务器对客户端的状态请求发送回应。此时服务器会在多人游戏画面表现为离线
- 添加了服务器向客户端发送的实体数据量控制
- 进度系统改动
实体广播
现在可以控制服务器向客户端发送实体数据的距离要求。
- 添加了
entity-broadcast-range-percentage 服务器属性，可以控制实体需要多近才会被发送到客户端。数值越高，玩家可看到的实体就越远，网络流量也就越大。可设定值为默认值的百分比，例如 50 表示默认距离的一半。
进度
- 添加了
player 检查项到每个触发器中（除了 impossible）
- 触发器中的实体检查项现在使用战利品表条件语法
扩展的实体检查
触发器中的实体检查项现在使用战利品表条件语法。
旧格式：
{
"trigger": "minecraft:player_killed_entity",
"conditions": {
"entity": {
"type": "minecraft:blaze"
}
}
}
现在可写成：
{
"trigger": "minecraft:player_killed_entity",
"conditions": {
"entity": [
{
"condition": "minecraft:entity_properties",
"predicate": {
"type": "minecraft:blaze"
},
"entity": "this"
}
]
}
}
注 1：就像战利品表，位于顶级数组中的所有条件都被满足时才会激活触发器。
注 2：要使用新功能，顶级元素必须是 JSON 数组。JSON 对象会按旧格式解析。
完整的触发器扩展清单：
- 每个触发器中的新字段
player
bred_animals - parent, partner, childchanneled_lightning - victimscured_zombie_villager - zombie, villagerfishing_rod_hooked - entitykilled_by_crossbow - victimsplayer_killed_entity - entityentity_killed_player - entityplayer_hurt_entity - entitysummoned_entity - entitytame_animal - entitytarget_hit - projectilevillager_trade - villager
触发器的其他改动
- 由于新增了
player，已有的 location、slept_in_bed、hero_of_the_village、voluntary_exile 现在可以放到 location 字段中（而不是顶级对象中）。旧格式依然被支持，但不再推荐。
