Live Stream #82: Physics Engines and Matter.js

[ad_1]
In this episode of The Coding Train, I provide an overview of physics engines. I a discuss a variety of libraries and the factors that go into picking an engine: 2D vs. 3D, collision detection, efficiency, etc.

I also take a look at the JavaScript physics engine Matter.js. I discuss you how to use this library for collisions in a p5.js sketch.

20:28 – Intro to Physics Engines
54:40 – Q&A on Physics Engines
1:10:13 – Intro to Matter.js
1:55:56 – Conclusion/short Q&A

    I feel like I am in the classroom again. But I really enjoy these classes. Wish I were in NYU when studying my master degree.

    so dan… the longer you put something off (i.e. forEach) the harder it is to get to it

    I use plinko for a random distribution algorithm. If you want a random number in a certain range that favours numbers nearby, just start with that number and add a random -1 or 1 every iteration. The number of iterations is the range + or – the target number. So, if you want a number between 25 and 75 that favours 50, start with 50 and do 25 iterations of plinko.

    what happened to the studio tour live stream from earlier today? I watched 2-3 minutes of it, but was busy at work, and had planned to watch it later.. bummer!

    yo I was wondering if you could update the vector stuff for p5.js? I am loving your stuff man!

    Hey Dan ! I think I found a great coding challenge on reddit, could you give a try at making this weird animation in p5 ? https://www.reddit.com/r/oddlysatisfying/comments/5xamjy/twist_and_turn/
