About

Omega engine is a Custom Game Engine developed using C++17 and DirectX 11.

The purpose to build this project to understand better how engines works under the hood to develop games.

How to use it

Prerequisite:

Visual Studio 2019

How to use:

Creating new windows c ++ project, adding the library as reference Omega.h and using the Omega Property sheet.

Example:

#include <OmegaEngine/Inc/Omega.h>

To use Dear ImGui API calls, it is necessary to include the header in .cpp files:

Example:

#include <ImGui\Inc\imgui.h>

Features

Artificial intelligence

• Implemented Agents, AIWorld and Entities, with that AIWorld can manage Agents along the world.
• Implemented Finite-State-Machine supporting Agents that can switching states behaviours along the AIWorld.
• Implmented pathfinding algorithms such as Breadth-first search, Depth-first search, Dijkstra and A-star allow for Agents moving along the graph.
• Implemented Steering behaviors module so that can help agents to move more natural and smoothly. Support behavios such as:
  • Alignment Group
  • Cohesion Group
  • Separation Group
  • Evade
  • Flee
  • Arrive
  • Seek
  • Wandering
  • Avoidance Obstacle
  • Hide

Core

• Implemented windows initialzaion using Win32 API.
• Implemented Memory management:
  • Block Allocator: Store and release a certain chunk of memory of objects avoiding memory fragmentation.
  • Typed Allocator: Custom Class types that can used whitin block allocator.
  • Handle: Handle Pool that manages accessibility and checks the validation of Handles.
• Implemented Meta System witch is usefull to retrieve objects information in run time: Including support : ARRAY, POINTER, CLASS, FIELD

Graphics

• Animation:
  • Implemented support to save and load animation keyframe using Assimp API once is extract model.
  • Implemented play animation once the file is loaded.
  • Implemented support to draw Skeletal using SimpleDraw with Debug UI (Dear ImGui).
  • Implemented Camera witch allow to move around and oriented into the world view.
  • Material: Support Textures, Colors,LightTypes, Material and Sampler.
• Mesh:
  • Implemented MeshBuilder withc allowed to rendere differents shapres such as: Cube,Plane, Sphere, Quads and Cylinder.
  • Implemented VertexTypes to cache information from MeshBuilder.
  • Implemented SimpleDraw using for visual debuging.
• Renderer:
  • Implemented TexturesManager to load, assign and render the textures using Direct3D as render pipeline.
  • Implemente SpriteRendererManager support to draw fonts and load 2D textures with position and scale.

Math

• Linear Algebra: Vector2, Vector3, Vector4, Matrix3, Matrix4, Quaternion and Perlin Noise.
• Geometry: AABB, OBB, Ray, Sphere, Circle, Line Segment, Rectangle and Plane.
• Implemented EngineMath as helper class to support all functionality such geometry intersections and helper function for linear algebra.

Physics

• Implmented Physics World to manage all physics particles and constraints in the scene.
• Implemented Particles system using Verlet integration.
• Constratints can be applied either fixed or spring constraints.

• Dear ImGui used for Debug UI
• DirectXTK DirectX Tool Kit for DirectX 11
• FW1FontWrapper used to render Fonts using Direct3D 11
• RapidJson used to serialize and deserilize Json files
