Highlights

AI

Bot SDK sample usage;
Hierarchical Finite State Machine (HFSM) used as the "Brain" for characters controlled by AI;
Filling a game match with Bots and picking random names from a text file;
Replacement of disconnected players by Bots;
Data driven architecture for AI Sensors;
Tactical sensors, used by the Bots to judge what tactics they want to perform;
Re-usable Input struct for both Players and Bots: both uses the same data and systems;
AI Director which polls team relevant data and defines the team Strategies;
AIMemory: store data and only make it available after an interval, and "forget" the data after an interval;

General

Usage of the HFSM to create the Game Manager, which dictates the flow of the game mode;
Data driven architecture for Habilities;
Usage of a Top-Down KCC;
Union-based strategy for character Attributes (such as Health, Speed, etc);
Custom baking of Level Design markers, used by the Bots as data on their decision making;
Context Steering: consider many "movement desire" vectors to result in a single one, used to movement the Bots;
Usage of the Callbacks version of the navigation system;

Game/Level Design

Usage of entity prototypes (prefabs and scene prototypes);
3 unique characters with 2 habilities each;
Coin Grab game mode: collect the coins in the map. The team who keeps 10+ coins for 15 seconds wins the match;
