xlibs & AlifePlus

xlibs is a modder's toolbox for STALKER Anomaly. It replaces raw X-Ray engine calls with safe, tested Lua wrappers — squad operations, smart terrain queries, entity identification, an event bus for mod-to-mod communication, MCM config, PDA messaging, logging, profiling, and more. If you're writing a STALKER mod, xlibs handles the engine so you can focus on gameplay.

AlifePlus is a behavior framework built on xlibs. The Zone is full of events — squads move between locations, NPCs die, stashes get looted, massacres happen. AlifePlus classifies these into causes and routes them to consequences: nearby stalkers investigate a massacre, bandits ambush a stash looter, a faction sends a revenge squad. Mods register a predicate and a handler; the framework handles throttling, protection, rate limiting, tracing, and lifecycle.

Right now every alife mod in the Anomaly ecosystem hooks the same engine callbacks independently, implements its own throttling, and fights other mods for control of the same squads. xlibs and AlifePlus exist so that mods can share one pipeline instead of reinventing it. Any mod author who wants to build on these systems is welcome — see the usage guide or reach out directly.
