Prolong – 模组介绍
📖 Description / 模组简介
Prolong is a lightweight Forge mod for Minecraft 1.20.1 that adds the /buff command, allowing you to extend the duration and increase the level of existing potion effects on the fly.
It supports all registered effects – vanilla or mod-added – via Minecraft's registry system.
Note: The mod now hard‑caps all effect levels at 255 to prevent numerical overflow.
You are still strongly encouraged to use theexparameter to set lower, game‑balanced limits for time and level according to your needs.
Prolong 是一个为 Minecraft 1.20.1 Forge 开发的轻量级模组,添加了 /buff 指令,让你随时延长已有药水效果的持续时间和等级。
它通过游戏注册表支持所有已注册的效果,包括原版和其他模组添加的效果。
注意: 本模组现已将所有效果等级硬性封顶为 255,防止数值溢出。
但仍强烈建议你使用ex参数根据实际游戏平衡设置更低的时间和等级上限。
