AgentScript is a minimalist Agent Based modeling system based on NetLogo semantics.

It has a Model/View architecture for which this is the Model. A set of Views will be provided in the future.

One such Three.js View is provided by as-app3d. Here is fire model, and a flocking model.

Obserable is also useful for Views, see: this example

Dual Build

AgentScript is based on es6 Modules (ESM) which are delivered as two Rollup bundles:

* UMD: agentscript.umd.js
* ESM: agentscript.esm.js

The UMD can be used in the browser as a <script> tag, and in Node using require()

The ESM is used in es6 import statements.

Both are available in minified form. All are in the project's dist/ directory.

The UMD's global name is AS

NPM Package

AgentScript is available as a npm scoped package: @redfish/agentscript.

To install the package, yarn add @redfish/agentscript. This places the bundles in node_modules/@redfish/agentscript/dist

To use the package as a CDN, use

View the unpkg.dashboard:

Developer Information

To clone the github repo:

  • cd to where you want the agentscript/ dir to appear.
  • git clone
  • cd agentscript # go to new repo
  • yarn install # install all dev dependencies
  • yarn build # complete the install

All workflow is npm run scripts. See package.json's scripts, or use yarn run for a list. JavaScript Standard Style is used.

Github Pages

A gh-page is used for the site. It contains the dist/ dir and a models/ dir with sample models also used for testing.

It uses the docs/ simplification for gh-page creation.

The gh-page hosts our sample models. The fire model can be run with:

The Github page can be used as a CDN for experimental use:


Our directory layout is:

bin: workflow scripts
dist: the umd and esm bundles with their min.js versions.
docs: gh-page
models: sample models used for tests and demos
src: individual agentscript es6 modules
test: test files
