This demo project offers an introduction to SmartFoxServer's MMO API and the concept of Area of Interest, which determines the spatial range of the events that will be received by players. This, in conjunction with the use of Server Variables to track the coordinates, allows creating a virtual environment in which potentially thousands of players can move around without overloading clients with updates.

This proof-of-concept also features a server-side Extension, which accomplishes two tasks: (1) shows how to optimize the user positioning logic and (2) simulates any number of active users via the creation of automated Non-Player Characters (NPC) moving around the map randomly, entering and leaving the Area of Interest of players continuously.
