wasm-fizzbuzz's Introduction

WebAssembly from Scratch: From FizzBuzz to DooM

Exploring WebAssembly from scratch from a backend-person-point-of-view. A story in four acts.

Welcome to my journey where I will explore some WebAssembly. We will start from scratch. My goal is to look at everything bottom-up, without much magic tooling or frameworks on our way. In this article, I prefer to build everything as much from scratch as possible.

Non-goal: We will not implement our own WebAssembly interpreter or runtime, but use existing ones, e.g., wabt or the Chrome and Firefox browsers.

Part 1) Introduction to WebAssembly
Part 2) Implementing FizzBuzz with WebAssembly by Hand
Part 3) Implementing FizzBuzz in Rust and Compiling to WebAssembly
Part 4) Porting 1997 DooM to WebAssembly from Scratch

Add a LICENSE

The tutorials are great! Thank you for putting this together.

I would like to build on the doom example for my own, "But can it run DOOM" project. Does this project have a LICENSE?

Freezes and does not save

doesnt save, when I try to it freezes until I refresh the page and reset my progress. When I open a new window it freezes and refuses to work until I refresh the page and reset my progress

Make the keybinds WASD, and left/right arrow keys for turning camera or use mouse

Keep CTRL as the shoot key

saving causes panic

When you try to save the game, it panics and gives this output

PANIC!!
panic occurred: "<no further information>" in file 'src/gamefile.rs' at line 63
PanicInfo { payload: Any { .. }, message: Some(open(doomsav0.dsg, 0, 1048240) unimplemented), location: Location { file: "src/gamefile.rs", line: 63, col: 5 } }

which i assume means you haven't got it to save in the browser local storage yet
