Build instructions (Wasm)

Prerequirements

• If you don't have Rust installed, see https://rustup.rs

• Then run the following commands:

• rustup target install wasm32-unknown-unknown

• cargo install -f wasm-bindgen-cli

Build the desktop version

• cargo build --release --target wasm32-unknown-unknown

• wasm-bindgen --out-dir ./out/ --target web ./target/wasm32-unknown-unknown/release/bevy-shoot-em-up.wasm

• cp -r ./assets ./out

Build the mobile version:

• cargo build --release --target wasm32-unknown-unknown --features mobile

• wasm-bindgen --out-dir ./out/mobile --target web ./target/wasm32-unknown-unknown/release/bevy-shoot-em-up.wasm

• cp -r ./assets ./out/mobile

Results

• The necessary files will be available at ./out

Optional extra optimazation

You can reduce the Wasm file size a little bit by running (must install binaryen first):

• wasm-opt -Oz out/bevy-shoot-em-up_bg.wasm -o out/bevy-shoot-em-up_bg.wasm

• wasm-opt -Oz out/mobile/bevy-shoot-em-up_bg.wasm -o out/mobile/bevy-shoot-em-up_bg.wasm
