5.17: Introduction to Matter.js – The Nature of Code

[ad_1]
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.

    But why we need to use push and pop functions?

    How do we edit the engine frame rate, to stop objects appear to be passing through the ground?

    29:08 lt happens because the speed is fast enough that the update rate can't handle it, so if the speed is 10 meters per second and the update rate is 1 time per second, the block will just jump 10 meters and all the path he did will not be calculated and any collision that should exist will not exist either

    I wish i had a professor like you in university. Your enthusiasm all alone is really contagious! Keep up your good work!

    A bit late to the party. But I come here only to check if you will introduce or recommend matter.js. Now I get the answer. I am glad that you choose this so I don't need to search around for more articles comparing different javascript physics libraries kind of stuff. I will just use matter.js and roll my sleeves on to work.

    Any particular reason why in all of the coding examples, you prefer to use function rather than ES6 class? Would love to know your take on this.

    console.log() seems to be doing nothing in my sketch. Does anyone know how to fix this?

    Why is this 5.17? In the p5.js tutorial playlist it only goes to 5.6 D:

    how do you tweak your code ? is it a shortcut ?

    how do you know so much, superbrain?

    This library is extremely cool but some implementations are really questionable…

  12. Jon Avatar

    matter.js maybe use requestAnimationFrame for his update routine instead of you calling update manually, it make sense

    Hey Dan, awesome video mate! keep motivating and teaching me more πŸ™‚

    Mostly a great video, for me it is always fun and inspiring to follow along your challenges, Dan! Btw, my name is also Daniel πŸ˜€
    Two issues tho:
    1. better to name world myWorld, and engine myEngine for readability. mixed world and World up and got stuck for a while :/

    2. Make annotation at 22 minutes stating that rotate(angle) and not rotate(radians(angle)) should be used.
    Got stuck at those places, otherwise great video! πŸ˜€

    I drew the bodies by calling beginShape() and then vertex() for each vertex of the body on the vertices array. Didn't need to worry about the angles nor the dimensions this way.

    Is it me or matter.js collision are kinda weird, they looks like they are intersecting…I dont know if its because of my OCD or is it normal ?

  18. alonetrio Avatar

    what about a little nice CODEF presentation ?? πŸ˜‰ πŸ˜‰

  19. Alon Kellner Avatar

    Video starts: "I am going to teach you how to use matter.js! Here's the problem… I don't really know matter.js…"
    And then: "What I'm gonna show you is me, trying to attempt to make a very simple example…"
    Three seconds in, the show has already been fully introduced, and we gained two extraordinary quotes from our dear Dan.

    Great video Dan! always enjoyable to watch. thank you πŸ™‚

    I think you need an alias " " for "this." πŸ˜€

    Dan, no one care's that you're copying code from a browser to a text editor. You do an awesome job explaining everything and you have amazing energy. When I watch your videos I know that you're going to ramble a bit and maybe mess up here or there, but there's something about that raw aspect of your channel that isn't in some of the other clean-cut tutorials out there. You show me that its okay to struggle, and that I'll get through it. Keep up the awesome work πŸ™‚ I know you put a lot of time and effort into this channel and I really appreciate it πŸ™‚

    What do you think about classical music @The Coding Train? πŸ™‚
    By the way, i like your videos. It's very fun to watch them.

    Is this the video you made a few years ago?

  25. Yanick Rochon Avatar

    "box"… this is why p5 should be namespaced, so it would also work better with es5 module loaders

    Awesome video dan!
