Go Game Engine using SDL for fun

nMage

nMage is a (hopefully!) high performance 3D Game Engine written in Go being developed live, with recordings posted on YouTube.

This project is being built with the goals being (in no particular order):

  • Sharing knowledge about less popular/less taught (e.g. compared to web dev), yet very powerful computing topics by building things and explaining as we go
  • Showing the development process of large, high performance software, including things like: learning unfamiliar topics, reading docs, fixing bugs and profiling and optimizing
  • To build a good game engine that can actually be used to develop games
  • Have fun through the entire thing!

Running the code

To run the project you need:

  • A recent version of Go installed
  • A C/C++ compiler installed and in your path
    • Windows: MingW or similar
    • Mac/Linux: Should be installed by default, but if not try GCC or Clang

Then simply clone and use go run .

Note: that it might take a while to run the first time because of downloading/compiling dependencies.

    intel mac busted again.

    just pulled dev branch and blows up again.

    Maybe should put in a github workflow to build off the makefile ?

    anyways here goes:

A small fantasy game engine in WASM using GoLang
 A small fantasy game engine in WASM using GoLang

The GoLang Fantasy Engine (GoLF Engine) is a retro game engine. It draws inspiration from fantasy console projects like pico-8, tic-80, and pyxle. Like those projects it is designed to be a retro-feeling game creation/playing tool. Unlike those projects GoLF is more minimal in scope and only provides an API and a small set of tools to help you create your games. Tools like an image editor and code editor are not built in. Despite this minimalism creating games in GoLF is still easy and should still maintain the retro game feel.
