How to make an OOP-Structured NPC in Roblox Studio ep. 4

Description:
In this video, we will cover setting up type definitions for this system, defining the functionality for NPC's being able to detect players, and then setting up a loop that repeatedly detects if any players (or other NPCs) are in sight. The sight functionality will include a limited field of view, a limited range, and also a minimum detection radius in which you can even be detected from behind.
