+# 自然之需：可抱起后代

-## Setup
+[English readme here](./README_en.md)
 
-For setup instructions, please see the [Fabric Documentation page](https://docs.fabricmc.net/develop/getting-started/creating-a-project#setting-up) related to the IDE that you are using.
+在使用 carryon 抱起生物的时候，默认是不能抱起敌对生物的——很合理，毕竟直觉上它们会反抗。
 
-## License
+但是，自然之需有一个选项“敌对后代不攻击玩家”，这意味着它们大概不会反抗你抱起来了。
 
-This template is available under the CC0 license. Feel free to learn from it and incorporate it in your own projects.
+因此，我们将此限制解除：如果是玩家产下的后代（无论谁生的，因为自然之需没有记录后代的母亲是哪个玩家），则无视敌对和体型限制，使其更符合直觉。
+
+## todo 
+此 mod 没有读取自然之需的配置 `NeedsOfNature.getConfig().pregnancyFriendlyMobsIgnorePlayers()` 也没有新建一个配置，因为作为只有一个选项的 mod，关掉还不如直接卸了方便些。

+# Needs of Nature: Picking Up Offspring
+
+[中文文档](./README.md)
+
+By default, the `carryon` mod prevents players from picking up hostile creatures—which makes sense, as one would intuitively expect them to resist.
+
+However, the "Needs of Nature" mod includes an option called "Spawned hostiles ignore players," implying that such offspring likely wouldn't resist being picked up.
+
+Therefore, we have lifted this restriction: if the offspring was produced by a player (regardless of which specific player gave birth, as "Needs of Nature" does not track the mother's identity), the hostility and size constraints are ignored, making the behavior more intuitive.
+
+## TODO
+This mod neither reads the "Needs of Nature" configuration setting `NeedsOfNature.getConfig().pregnancyFriendlyMobsIgnorePlayers()` nor introduces a new config option; since this mod has only a single function, simply uninstalling it is more convenient than toggling a setting off.
