About this Mod
WAC World Altitude Control 世界高度控制
这个mod不能解决高度不能超过mc数据结构限制的问题,因为这会摧毁兼容性!
This mod doesn't solve the problem that the height can't exceed the mc data structure limit because it would destroy compatibility
这个Mod用于控制Minecraft维度高度,可在配置文件或在HutoolCore的Web编辑器中进行配置。
This mod is used to control the height of Minecraft dimensions and can be configured in the configuration file or in HutoolCore's web editor.
它的原理是Minecraft在创建ServerLevel(ServerWorld)时修改ServerLevel(ServerWorld)的高度配置。
It works by Minecraft modifying the height configuration of the ServerLevel (ServerWorld) when it is created.
以下为对参数的解释:
The following is an explanation of the parameters (note in Chinese):
| 参数 | 注释 |
|---|---|
| id | 世界ID |
| logical_height | 玩家使用紫颂果或下界传送门可以到达的总高度。不会影响超过该限制高度的既有传送门。取值为0到4064的闭区间,且不能大于 height。 |
| min_y | 该维度中可以存在方块的最低高度。数值必须在-2032至2031之间且为16的整数倍(也就是说,-2032是最小有效值,2016是最大有效值)。 |
| height | 该维度中可以存在方块的总高度。数值必须在16至4064之间且为16的整数倍。维度中可以存在方块的最大高度值为min_y与height值之和减去1,不能超过2031。 |

Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with World Altitude Control – how to optimize performance?
