Overload pillars are:
Overload is divided into 12 modules (10 DLLs and 2 executables):
The Overload SDK is the core of the engine. It is a set of libraries that our applications (
OvEditor) are using.
We designed theses libraries with reusability in mind. They are extremely modular and easy to extract from a game engine context.
OvAnalytics: Code and hardware profiling
OvDebug: Logging, assertions
OvTools: Serialization, ini files, events, time
OvMaths: Vectors, Matrices, Quaternion, Transform
OvAudio: Wraps irrKlang
OvPhysics: Wraps Bullet3
OvRendering: Rendering engine using OpenGL
OvWindowing: GLFW + Windows API wrapper
OvUI: Dear imGui wrapped into an event-based and component-based UI system
OvCore: Mediator, resource management, scripting, component-based scene system
OvGame: Uses OvCore, asset dependent, generic executable for any game built with Overload
OvEditor: Uses OvCore, expose game development to the end-user (From creation to building)
Initially, Overload was a graduation project. We were 3 (Benjamin VIRANIN, Max BRUN and Adrien GIVRY) working on it for 5 months. We had to create a game engine from scratch, using the fewest libraries possible.
Our goals for this project were:
We spent about a month designing our initial architecture. We tried to provide a technical solution with UML diagrams, flowcharts, package diagrams and use-case diagrams. This was a long and tedious work, but it really helped us to start the production with a clear vision of the engine. We defined some coding convention to ensure that all of our work will stay homogeneous during the production. Defining these kinds of rules is crucial to keep a maintainable code during the whole project.
The production made us realize that we had a naive idea of what a game engine is. During this phase our architecture has evolved. We found that our initial architecture was sometimes too complex, non-optimal. We went back to architecture design multiple times during the project.
Here is a non-exhaustive list of Overload main features:
Again, a non-exhaustive list of Overload in-coming features:
We made this project using Visual Studio 2019. If you want to compile Overload, you should consider using this IDE.
Overload only targets Windows x64.
Overload is licenced under an MIT licence.
