Light Helmet

Light Helmet（头盔灯） 是一个 Minecraft Fabric 模组，适用于 Minecraft 1.21.1。它添加了一个特殊的头盔——当玩家佩戴时，会在头顶自动生成一个光源方块，照亮周围区域；摘下后光源自动消失。

合成配方 ：将铁头盔放在工作台中央，周围 8 格放置煤炭即可合成。

主要特性：

• 佩戴头盔时动态生成光源，跟随玩家移动
• 摘下头盔时光源自动清除，不留下残余方块
• 轻量级实现，通过 Mixin 注入玩家 tick 逻辑，每 4 tick 检测一次，性能友好

Light Helmet is a Minecraft Fabric mod for version 1.21.1. It adds a special helmet that automatically places a light source block above the player’s head when worn, illuminating the surrounding area. The light is removed when the helmet is taken off.

Crafting Recipe : Place an iron helmet in the center of a crafting table, surrounded by 8 coal.

Key Features:

• Dynamically spawns a light block that follows the player as they move
• Automatically cleans up the light block when the helmet is unequipped — no leftover blocks
• Lightweight implementation using Mixin injection into the player tick loop, checking every 4 ticks for optimal performance
