About the Unbreakapack data pack

It's a shame when some very strong equipment is damaged because it doesn't have enchantment experience to repair.

This data pack gives all durable items in the player's inventory and durable items within a 5-block radius of the player an indestructible tag, effectively making the tools unbreakable.

Note: All items with less than full durability must be repaired to full durability in order to receive the indestructible tag.

It supports multiplayer gameplay.

This data pack has been successfully ported to a Mod.

当一些极强的装备,因为没附魔经验修复而损坏,这非常令人惋惜。

这个数据包通过给玩家背包内所有有耐久的物品和玩家附近5格有耐久的物品无法破坏的标签,达到使工具变得无法破坏的效果。

注意:所有不满耐久的物品需要进行修复成满耐久物品才会有无法破坏的标签。

支持多人游戏。

已移植此数据包为模组。
