Concussion Engine

Concussion Engine is a small, modular game engine written in C# and built on MonoGame that uses an Entity-Component-System (ECS) style architecture. It utilises data-oriented design to optimise CPU caching and performance.

This was developed as part of undergrad dissertation.

Overview

• Core engine: Hassie.ConcussionEngine.Engine — contains core interfaces and systems (entity manager, event manager, world management, systems for update/render/physics/input, and collision handling).
• Example games: Hassie.ConcussionEngine.Pong and Hassie.ConcussionEngine.MegaPong — simple Pong-like games built on the engine.
• Tests: Hassie.ConcussionEngine.Tests.Engine — unit tests for engine components.

Repository structure

• Hassie.ConcussionEngine.Engine/ — engine implementation (Core, Entity, Event, System, World, Physics, Render, Input, Collision, Component folders).
• Hassie.ConcussionEngine.Pong/ — Pong example game and content.
• Hassie.ConcussionEngine.MegaPong/ — MegaPong example game and content.
• Hassie.ConcussionEngine.Tests.Engine/ — unit tests for engine modules.
• Concussion Engine.sln — Visual Studio solution file.

Requirements

• .NET Core 3
• MonoGame 3.x

Build

From the repository root, you can build the solution with the .NET CLI:

dotnet build "Concussion Engine.sln"

Run

To run one of the example games from the repository root:

dotnet run --project Hassie.ConcussionEngine.Pong/Hassie.ConcussionEngine.Pong.csproj

Or for MegaPong:

dotnet run --project Hassie.ConcussionEngine.MegaPong/Hassie.ConcussionEngine.MegaPong.csproj

Tests

Run tests with:

dotnet test Hassie.ConcussionEngine.Tests.Engine/Hassie.ConcussionEngine.Tests.Engine.csproj
