The Asteroids engine is a C++ 2D engine.

Features:

• Simplistic Networking interface (with automatic syncing of entities and components, and is quite resilient to lag)
• Networked components and entities
• Networked 2D physics
• GUI system (powered by TGUI)
• Window and audio system (powered by SFML)
• Logging and error handling system

The engine is named after where it originated from, the game Asteroids. Documentation is a work in progress, but most of the code is self-explanatory.

There are many libraries that the asteroids engine uses:

• bitsery: For serialization and deserialization of networking messages
• flecs: Entity-Component-System handling
• GameNetworkingSockets: Steam's networking library, used for of course networking
• SFML: Audio, Window, Rendering handling
• TGUI: GUI handling
• THST: Spatial partitioning library
• nlohman/json: For config reading and writing
• boost: various utility functions

It is required that you use VCPKG to build this engine, it is part of this engine's toolchain on Windows. Below is a step by step guide on how to install vcpkg

Installing vcpkg:

$ git clone https://github.com/microsoft/vcpkg
$ .\vcpkg\bootstrap-vcpkg.bat
$ .\vcpkg\vcpkg integrate install

Installing the neccessary packages with vcpkg

.\vcpkg\vcpkg install GameNetworkingSockets --triplet=x64-windows
.\vcpkg\vcpkg install protobuf --triplet=x64-windows

This is a crucial step! Guide yourself to the "Edit Enviroment Variables for your account" panel, next click "new." In the "variable name" field type "VCPKG_ROOT," and then under the "variable value" field insert the file path of where you cloned vcpkg, including the vcpkg directory itself. The variable value field should look something like this: "C:/My/path/to/the/thing/vcpkg"

Finally, in between where you call cmake_minimum_required() and your project(), insert this:

if(WIN32)
    message("Using the VCPKG Toolchain for Windows")
    set(CMAKE_TOOLCHAIN_FILE "$ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake")
endif()
