FRAG

FRAG is a WIP game engine written in the Nim programming language.

The current focus of development is on the 3D Vulkan renderer and tooling.

FRAG is being developed alongside a science-fiction roguelike game, so feature development will be limited in scope.

This document will be updated as new capabilities and examples are added to the project.

Platforms

FRAG is being developed on a MacBook Pro, so macOS will be the first supported platform. Windows and Linux support will follow, in that order.

Compiler Tested With	Operating System

Installation

Use the Nimble package manager to install FRAG.

git clone git@github.com:zacharycarter/frag.git && cd frag
nimble deps
nimble install
frag

Usage

FRAG is still in early development, and doesn’t do much yet.

import frag
proc init() =
  echo "initializing app"
proc frame() =
  discard
proc event() =
  discard
proc cleanup() =
  echo "cleaning up"
proc main() =
  var appDesc = AppDesc(
    initCb: init,
    frameCb: frame,
    eventCb: event,
    cleanupCb: cleanup,
  )
  run(appDesc)
when isMainModule:
  main()

Features

• Auto-generated bindings for volk, Vulkan Memory Allocator and GLFW via Nimterop
• Vulkan renderer (WIP)
• Direct3D 12 renderer (planned)
• Metal renderer (planned)

Third party dependencies

• Nimterop: A Nim package that aims to make C/C++ interop seamless
• volk: Meta-loader for Vulkan
• Vulkan Memory Allocator: Easy to integrate Vulkan memory allocation library
• GLFW: Multi-platform library for OpenGL, OpenGL ES and Vulkan application development
