Overview
This sample is provided with full source code and demonstrates how Quantum can be used to create a top-down twin stick shooter game.
It showcases AI systems present in Bot SDK in conjunction to other auxilliary implementations such as an AI Director to provide team strategy, data-driven AI Sensors and Habilities architecture and much more.

Technical Info
- Unity: 2021.3.30f1;
- Platforms: PC (Windows / Mac), and Mobile (Android);
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;
