playmill

Playmill implements a simple factory-game simulation in Rust

Author: Jared Rhine @ [email protected]

Background

The author is not an experienced Rust developer. This repository was built is a fun learning exercise, inspired by the "factory simulation" genre of games (Satisfactory and Dyson Sphere Project primarily, based on Factorio). Do not take this code very seriously.

Status

Works:

• Compiles in Rust
• Displays the status of the world using ASCII with a terminal
• Runs in a continuous loop at 4 frames per second

Future directions:

• Buildings can be connected
• Conveyors pass their input to their output
• A new building that can create resources
• Multiple kinds of resources
• More idiomatic Rust code
• Split into multiple files
• Tests
• Make the post-tick sleep adjust based on how long the tick took to ran, to stablize run speed
• A new building that can combine two kinds of resources to make a new kind

Using Playmill

1. Get this repository:

git clone https://github.com/jaredrhine/playmill
cd playmill

1. Install asdf or otherwise build a modern Rust installation providing cargo.

asdf install

1. Use cargo to build and execute the playmill application.

cargo run

1. Playmill will clear the screen and print a view of the simulated world at 4 frames per second.

   • There will likely be flashing as your terminal repaints frequently.

   • There is an on-screen reminder of two available keys.

     • Press "q" to quit.
     • Press the spacebar to pause and to resume.

   • The terminal support will likely only work on a Unix-like terminal. Windows-based shells may have problems.
