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.

    Extensive refactoring Ability to choose opponent (human or engine)

    • Code refactoring: separated chess playing "agents" (humans, UCI, random, the future CPU player etc.) from the UI and established an abstraction to be able to exchange them with each other (this will also be beneficial for future multiplayer mode).

    • Choose type of opponent (human, engine/random) and store the type of opponent in preferences.

    • Choose White or Black (or to let the engines play each other) and store this in preferences.
