3D game engine/framework in C.


























## About

- 3D game engine v2, written in C.

- v2 is a major overhaul from [previous v1 engine](https://github.com/fwk3d/v1).

- v2 is faster, smaller and stronger than v1.

- v2 is a work-in-progress, though. [Changelog](CHANGELOG.md).

## Features and wishlist

- [x] ~~Rich build system, Royaltie fee, Licensing clauses, Full featured, Fast, Modern C++~~.

- [x] Batch makefile, Free, Unlicensed, Small, Naive, Simple C.

- [ ] TBD.

## Quickstart

- Double-click `MAKE.bat`. Launch `hello.exe` when done.

- Alternatively,

  - `make [asan] [debug|devel|release|retail] [embed] file1.c file2.cc ...` for custom builds.

- Other commands,

  - `make tidy` to clean environment.

  - `make sync` to sync repo to latest.

  - `make plug` to un/install extensions.

- Tested with VS2019 and VS2022 installations.

## Extensions💙

- Currently, [all these extensions are hosted on github](https://github.com/search?q=topic%3Aext-v2&type=repositories&s=updated&o=desc).

- It is planned that the hello demo will be used to un/install extensions in the future.

- For now, you can un/install extensions via `make plug` script:

  - `make plug dir`

  - `make plug [add|del|syn] *`

  - `make plug [add|del|syn] user/repo`

  - `make plug [add|del|syn] @filelist.txt`
