#### 💡 What is Oxyde?

**Oxyde** is a modular Rust-based SDK for building NPCs that think, feel, remember, and act — powered by LLMs.\
It gives developers a unified interface to deploy emotionally aware, goal-oriented agents across **Unity, Unreal, WebAssembly, or native Rust** environments.

Where traditional NPCs are hardcoded or rule-bound, Oxyde agents are **emergent** — dynamically responding to memory, emotion, and goals in real-time conversations.

***

#### 🎯 Why Oxyde Exists

Conventional NPCs struggle with:

* 🔁 Repetitive dialogue
* ⚙️ Overcomplicated behavior trees
* 🧠 No persistent memory or emotion
* 📡 Difficult LLM integration

**Oxyde bridges the gap** between game engines and modern AI — offering game-ready autonomy without massive overhead.
