Side Vein Effect

A video game developed during Bevy Jam 3.

You play as a nanomachine drug in a patient's bloodstream. You need to shoot the germs and protect the blood cells. If you miss the germs, it will create side-effects on the sides of the vein.

Clone the repository

This repository uses Git-LFS to store the game assets. Make sure that Git-LFS is installed on your system. You can use the following commands to clone the repository and pull the files stored by Git-LFS:

git clone https://github.com/necrashter/side-vein-effect
cd side-vein-effect
git lfs install
git lfs pull
git fetch

Run Localy

It can be built and run like a regular Bevy game:

# Run in debug mode:
cargo run

# Run in debug mode but compile using dynamic linking.
# This makes subsequent builds faster.
cargo run --features bevy/dynamic_linking

# Run in release mode with all optimizations.
cargo run --release

Deploy to Web

Install the prerequisites:

rustup target install wasm32-unknown-unknown
cargo install wasm-bindgen-cli

Build:

cargo build --release --target wasm32-unknown-unknown
wasm-bindgen --no-typescript --out-name game --out-dir web --target web target/wasm32-unknown-unknown/release/side-vein-effect.wasm
cp -r assets/ web/

Optionally, use wasm-opt to optimize the game. This decreases the size of the .wasm executable and also reduces the audio glitches caused by buffer underruns (which presumably happen because the web build is single-threaded).

# Install wasm-opt on Ubuntu
sudo apt install binaryen

cd web
wasm-opt -O -ol 100 -s 100 -o game_bg.wasm game_bg.wasm

You can use the HTTP server in Python to test the web build:

python3 -m http.server

Now navigate to http://0.0.0.0:8000/ with your web browser.
