3D playground built on three.js and cannon.js.

Live demo

Final update (20. Feb 2023)

As I have no more interest in developing this project, it comes to a conclusion. In order to remain honest about the true state of the project, I am archiving this repository.

• If you wish to modify Sketchbook feel free to fork it.
• To see if someone is currently maintaining a fork, check out the Network Graph.
• The NPM package name is available, and I'll give it away to anyone who asks for it. The package has never worked properly.

📒 Sketchbook

Simple web based game engine built on three.js and cannon.js focused on third-person character controls and related gameplay mechanics.

Mostly a playground for exploring how conventional third person gameplay mechanics found in modern games work and recreating them in a general way.

Features

• World
  • Three.js scene
  • Cannon.js physics
  • Variable timescale
  • Frame skipping
  • FXAA anti-aliasing
• Characters
  • Third-person camera
  • Raycast character controller with capsule collisions
  • General state system
  • Character AI
• Vehicles
  • Cars
  • Airplanes
  • Helicopters

All planned features can be found in the GitHub Projects.

Usage

You can define your own scenes in Blender, and then read them with Sketchbook. Sketchbook needs to run on a local server such as http-server or webpack-dev-server to be able to load external assets.

1. Import:

<script src="sketchbook.min.js"></script>

2. Load a glb scene defined in Blender:

const world = new Sketchbook.World('scene.glb');
