资源系统概述 / Resource System Overview#
《最后生还者第二部》的资源系统基于搜索-合成-消耗循环。玩家在场景中搜索各类基础资源，在工作台或背包中合成消耗品和弹药。 The Last of Us Part II resource system operates on a Search-Craft-Consume cycle. Players search environments for basic resources, then craft consumables and ammunition at workbenches or from the backpack.
资源稀缺度根据游戏难度动态调整，且与当前持有量相关——当某项资源极端匮乏时，场景中该资源的刷新概率会隐性提高（绝地难度下此机制减弱）。 Resource scarcity scales dynamically with game difficulty and is correlated with current inventory — when a resource is critically low, its spawn probability in scenes increases implicitly (this mechanism is reduced on Grounded difficulty).
背包容量 / Inventory Capacity：初始背包有有限容量，通过收集**背包升级（Holster Upgrades）**扩充口袋数量。最大可持有每种资源15-20个单位不等。 The initial backpack has limited capacity. Pocket count expands through collecting Holster Upgrades. Maximum capacity per resource type ranges from 15-20 units.
