## Overview

This repository is a set of Unity course assignments, not one integrated application. A student opens an assignment scene and studies or runs a graphics, collision-detection, or NPC behavior demonstration. The README describes normal mapping as P2, while the tree places normal-map shaders in A0_LightsOn; no separate P2 runtime project is present. Relationships are limited to documented behavior and asset organization because no source excerpts were provided.
