Documentation

The PhET Development Overview is the most complete guide to PhET Simulation Development. This guide includes how to obtain simulation code and its dependencies, notes about architecture & design, how to test and build the sims, as well as other important information.

Quick Start

(1) Clone the simulation and its dependencies:

git clone https://github.com/phetsims/assert.git
git clone https://github.com/phetsims/axon.git
git clone https://github.com/phetsims/babel.git
git clone https://github.com/phetsims/brand.git
git clone https://github.com/phetsims/chipper.git
git clone https://github.com/phetsims/dot.git
git clone https://github.com/phetsims/forces-and-motion-basics.git
git clone https://github.com/phetsims/joist.git
git clone https://github.com/phetsims/kite.git
git clone https://github.com/phetsims/perennial.git perennial-alias
git clone https://github.com/phetsims/phet-core.git
git clone https://github.com/phetsims/phetcommon.git
git clone https://github.com/phetsims/phetmarks.git
git clone https://github.com/phetsims/query-string-machine.git
git clone https://github.com/phetsims/scenery.git
git clone https://github.com/phetsims/scenery-phet.git
git clone https://github.com/phetsims/sherpa.git
git clone https://github.com/phetsims/sun.git
git clone https://github.com/phetsims/tambo.git
git clone https://github.com/phetsims/tandem.git
git clone https://github.com/phetsims/twixt.git
git clone https://github.com/phetsims/utterance-queue.git

(2) Install dev dependencies:

cd chipper
npm install
cd ../perennial-alias
npm install
cd ../forces-and-motion-basics
npm install

(3) Transpile the TypeScript code to JavaScript by running grunt output-js-project --live. This starts a file-watching process that will automatically transpile new or changed files.

(4) In a new terminal/command prompt, start an http-server

(5) Open in the browser: http://localhost/forces-and-motion-basics/forces-and-motion-basics_en.html (You will probably need to modify this URL based on your HTTP port and relative path.)

Optional: Build the simulation into a single file

(1) Change directory to the simulation directory: cd ../forces-and-motion-basics

(2) Build the sim: grunt --brands=adapted-from-phet. It is safe to ignore warnings like >> WARNING404: Skipping potentially non-public dependency, which indicate that non-public PhET-iO code is not being included in the build.

(3) Open in the browser: http://localhost/forces-and-motion-basics/build/adapted-from-phet/forces-and-motion-basics_en_adapted-from-phet.html (You will probably need to modify this URL based on your HTTP port and relative path.)
