Rustysnake is a Rust-based implementation of the classic snake game which you may have played on your Nokia phone in the past.
What makes it special ?
- It's implemented in Rust.
- It's designed to run on a Raspberry PI with a Unicorn Hat HD.
- It's designed to take it's input from a USB input device that supports buttons typically found on a gamepad. FYI: I am using this one.
I was interested to learn more about Rust and the only way to learn a new programming language is by using it. To make it a little more interesting than just a console application, I decided to make a small game for my daughter on the Raspberry Pi.
If you want to build for your host PC, first modify one line in Cargo.toml and then
cargo build
If you want to cross-compile for the raspberry pi (assuming you have the toolchain for the latter installed).
HOST=x86_64-unknown-linux-gnu cargo build --target=armv7-unknown-linux-gnueabihf
The program only takes one argument: where the device file of the input device can be found.
Typically, you can find it as /dev/input/event0 if your raspberry pi only has one input device.
Use the arrow to move the snake around. Whenever the snake eats the bait, the snake grows one unit. Also, the game goes a little faster after every successful bite. If the snake "eats" itself, the game ends. This stops the program altogether. Pressing the color buttons on the controller, changes the color of the snake (you can thank my daughter for this feature).
