jayrave / runner

An endless runner game in Rust

Runner

The web version of the game is live at https://jayrave.github.io/runner/

This is my first attempt at building a game with animation! I decided to try my hand at using the Entity Component System architecture for this. These are the main modules:

• core: has the core game mechanics (everything except windowing & rendering)
• sdl2: uses sdl2 & core module for desktop builds
• quicksilver: uses quicksilver & core module for wasm builds

Quicksilver can also do desktop builds, but I initially started the game with sdl2 & wanted to see if I could abstract it enough where I could have multiple front-ends. Turned out to be pretty exciting. Between those 2, I can target the majority of the platforms => Windows, Linux, MacOS, Android, iOS & Web.

Build instructions

• sdl2: cargo run
• quicksilver:
  • desktop: cargo run --features desktop
  • web: cargo web start --features web

Assets

You can probably see that our sprite sheets carry quite a bit of extra sprites. It could be optimized by building a sheet with only the sprites we care about. I tried doing it but found it to be pretty manual & boring. Presumably, there are tools which can automate this (sprite builders, RON files etc.), but I haven't invested enough time in those yet. This way of just including the whole sprite sheet itself makes it pretty easy while developing.
