In this video, I attempt to answer the questions: (1) what are Physics Engines? and (2) why would you want to use them? I discuss some common physics engines and their various pros/cons – box2d, toxiclibs, matter.js.

This video is an introduction to a tutorial series on the physics engine Box2D. The programming language is Java (with the jbox2d port). The Box2D for Processing library is demonstrated. In the video it’s called the old name: “PBox2D”

This video goes over the basic elements of the Box2D world � body, shape, fixture, joint.

This video covers the Box2D coordinate system and how to use the Vec2 class.

This video covers the basics of adding Box2D to a Processing sketch. This is part 1. Part 2 gets to the code.

This video covers the basics of adding Box2D to a Processing sketch. This is part 2.

This video covers things that don’t move in Box2D.

This video covers how to create shapes beyond rectangles and circles in Box2D using PolygonShape and by attaching multiple shapes to one body.

This video shows how to create a distance joint.

This video introduces the concept of joints in Box2D and demonstrates how to create a revolute joint.

This video shows demonstrates how to move objects in Box2D manually through the use of a mouse joint or a kinematic body type.

This video demonstrates how to apply forces to objects in Box2D. Simple wind and gravitational attraction are demonstrated.

This video demonstrates how to listen for collisions and trigger events at the moment of collision in Box2D.

This video is an introduction to the physics engine Matter.js, a 2D JavaScript physics library that supports rigid body collisions and constraints. In this video I show you how to set up your code to use the library in combination with p5.js for rendering.

In this video, I expand on the example from “Introduction to Matter.js” by adding angled static shapes and circular bodies to the physics simulation.

This video is the third in a series on the matter.js physics engine. Here I look at how to delete off-screen bodies from the physics world, removing them from both my particle array as well as Matter.world.

In this video, I show you how to you can create constraints to connect rigid bodies in matter.js (with p5.js).

In this video, I demonstrate how to use mouse constraints with matter.js to add mouse interaction to a p5.js physics simulation sketch.
