# Bevy Combat

It's a bevy port of my [ECS Combat](https://github.com/ElliotB256/ECSCombat/) Unity demo.

Check out the [web demo](https://elliotb256.github.io/bevy_combat/) in your browser.

You can use the - and = keys to speed up and slow down time (make sure you have focussed the browser window).

## Getting Started

To build and deploy for web:

```

cargo make serve

```

To run for pc:

```

cargo run

```

## Building for web (fast)

Make sure you have added the wasm target to your toolchain:

```

rustup target add wasm32-unknown-unknown

```

If you do not have `wasm-server-runner`, install it via

```

cargo install wasm-server-runner

```

Afterwards, you can build and run in your browser:

```

cargo run --target wasm32-unknown-unknown

```

For more info on web deployment, see [the bevy book](https://bevy-cheatbook.github.io/platforms/wasm.html).

### Building for itch.io

Following [these instructions](https://bevy-cheatbook.github.io/platforms/wasm/webpage.html)...

itch.io build requires

```

cargo install wasm-bindgen-cli

```

Build the wasm target, then run `wasm-bindgen`. After, optimize the generated `.wasm`:

```

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

wasm-bindgen --no-typescript --target web --out-dir ./out/ --out-name "game" ./target/wasm32-unknown-unknown/release/bevy_combat.wasm

```

If you want to optimize further:

```

wasm-bindgen --no-typescript --target web --out-dir ./out/ --out-name "preopt_game" ./target/wasm32-unknown-unknown/release/bevy_combat.wasm

wasm-opt -O -ol 100 -s 100 -o game.wasm preopt_game.wasm

```

Copy the assets folder to `/out`. Copy `web/index.html` to `/out/index.html`

Zip the `out` folder, upload to itch.io, and celebrate!
