A simple C++ game engine

My goal when writing µEngine was to learn about the internal workings of a game engine. µEngine aims mostly to be easy-to-understand. This is certainly not an attempt at a performance-driven or highly-configurable game engine.

• C++20 compliant
• Configurable settings
• Command line arguments
• Uses a modern build system

By order of likeliness:

• Configurable levels
• Cross-platform

• SFML
• Boost Property Tree
• Boost Program Options

• Doxygen

• --help: display µEngine options
• --settings-file: path to the settings file - defaults to config/settings.toml
• --settings-format: format of the settings file - defaults to 'toml'
• '--dry-run': only run the set up and tear down steps
• '--disable-graphics': disable the graphics manager

The settings in config/settings.toml correspond to the following table:

The "official" build system for µEngine is CMake, but the Makefile is there to provide "aliases" to avoid typing long commands every time.

The usual build steps go like this:

1. Install dependencies
2. Clone the repo
3. make release or make debug depending on what you want
4. ./build/µEngine

Otherwise you can always follow the typical CMake build steps:

1. Install dependencies
2. Clone the repo
3. mkdir build && cd build
4. cmake .. && make
5. ./µEngine

1. Install dependencies
2. Clone the repo
3. make doc
4. Open build/html/index.html with the web browser of your choice
