Blazar Game Engine

Blazar is a flexable C++ game engine.

Why a game engine?

This engine is being created for a large scale space game. These types of games generally do not fit well into generic game engines as they try and do too much.

Space games are unique due to:

• Large scales
• Large amount of procedural generation
• Minimal authored content
• Large amount of objects.

Additionally, for games played over the network, a large amount of determinism is required. Current game engines make all of this a challenge because they're built for completely authored experiences with no or little procedural generation, and a well known set of objects.

I've tried for a long time to retrofit a suitable system into the likes of Unity or Unreal, but I either found the system unworkable, unusable, or slow.

I plan to update approxamately 100,000 entities every tick through 20+ systems.

Additionally, I plan on making games that are 2.5D, though I want the engine to be generic. I need good 2D rendering support with batching and all the goodness that comes with that, but also 3D rendering support. This is why there is a custom renderer instead of reusing a library.

Goals

• Robust Entity Component System
• ImGUI Based Debugging System
• ImGUI Based Authoring System for Procedural Generation
• Material / Shader system
• Sprite tools, including sprite atlas support.
• Cross Platform (Windows, Mac, Linux)
• Easy asset loading
• Robust VFS supporting different archive formats (including bare files).

Building

Currently, Blazar supports Windows and Linux.

Requirements:

• Premake
• C++17 compiler
• Visual Studio 2019

Instructions (Windows only for now)

1. Run generate_project.bat to create a vs project
2. Run scripts/reflection_update.py in the Blazar folder to generate reflection information
3. Run generate_project.bat again to make sure
4. Open .sln file.
5. Compile!
