Screeps Clockwork

Usage

This guide will assume you're using Rollup along the lines of the Screeps Typescript starter kit.

Set up dependencies:

npm install screeps-clockwork
npm install -D @rollup/plugin-wasm rollup-plugin-copy
Copy

Update your Rollup build script to copy the WASM binary to your dist folder:

// add to existing dependencies
import wasm from '@rollup/plugin-wasm';
import copy from 'rollup-plugin-copy';

// ...

export default {
  // ...
  external: ['screeps_clockwork.wasm'],
  plugins: [
    clear({ targets: ['dist'] }),
    wasm(),
    copy({
      targets: [
        {
          src: 'node_modules/screeps-clockwork/dist/screeps_clockwork.wasm',
          dest: 'dist'
        }
      ]
    }),
    // ...
    screeps({ config: cfg, dryRun: cfg == null })
  ]
};
Copy

rollup-plugin-screeps will automatically push the wasm file out when it deploys.

Then, in your main loop, call the initialize function before running anything else:

import { initialize } from 'screeps-clockwork';
export const loop = () => {
  initialize();
  // ...
};
Copy

Dev Setup

Dependencies to build and run the project:

# Install Rust + Cargo via rustup
curl https://sh.rustup.rs -sSf | sh

# Install wasm-pack
curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh

# Add rust-src component
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu

# Set nightly as the default
rustup default nightly

# Install nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

# Install node
nvm install --lts
nvm use --lts
nvm alias default --lts # optional

# install project dependencies
npm install
Copy

To build the project:

npm run build
Copy

To set up the local Screeps server, you'll need to have docker installed:

cp .env.sample .env # fill this out with the path to your Screeps .nw package and Steam key
cp screeps.sample.json screeps.json # optionally, override this to connect to your own local Screeps server
./reset-docker.sh
Copy

Once running, you can log in and spawn into the server with the local screeps-steamless-client.

• Password: passw0rd

To deploy the test codebase, once the server is running:

npm run watch
Copy

Set up commitizen and pre-commit for conventional commits:

# requires Python 3.8+
pip install --user -U commitizen pre-commit
pre-commit install
Copy
