FIEA Game Engine

Cross platform Data-Driven game engine developed using modern C++ standard ( C++17 )

This engine is component-based & JSON is used as a configuration language.

Features custom implementation of various STL like containers :-

• Singly Linked List
• Vector
• Hashmap

Features Various design patterns :-

• Singleton
• Composite
• Factory
• Chain of Responsibility
• Observer

Various components of this engine are :-

• Datum : A run-time polymorphic homogeneous container which stores values of type Integer, Float, Vector, Matrix, Table, String, Pointer.
• Scope : A Scope is a dynamic hierarchical database which stores Datums by name.
• Factory : A class that allows instantiation of other objects at runtime by their Typename. Suitable for use with any interface class which has a default constructor.
• World contains everything that exists in the game. Its divided into Sectors. Sectors can be considered as a part of the world ( Scene ). Sectors are composed of Entities which are basic building block of world.
• Action : It is a specific action that can be performed by any entity
• Reaction : Reaction is a abstract base class which ties Event System to Rest of the Engine which acts as a response to an action
• Event System : Entities can subscribe to events. Events are processed and delivered through an event queue which resides in the World.

Me and my collegues ported a 2D rapid prototype game made in Unity engine into this custom engine. Gameplay video for the same can be found here. https://www.youtube.com/watch?v=AJFU5yuVLiY
