    You are an excellent teacher! I often find myself reviewing fundamentals to stay sharp and nothing's worse than wasting time in an incoherent video or verbose documentation. Your flow is just right – informative, concise, and even entertaining so thank you!

    The bubbles disappearing with splice is the same thing many games do with things like bullet decals, casings, particles.

    Awe You can also use array.split(indexOf(whatever), 1); which checks what’s the index of whatever 😂

  • comment-avatar

    How should I make an object in p5.js, by using the
    var bubble = function (){}
    method or should I use
    function bubble(){}

    What's the difference

    * Need help!! Facing the issue while doing the same task in processing..

    Bubble[] bubbles = new Bubble[50];

    void setup() {
    size(600, 400);
    for(int i = 0; i < bubbles.length; i++)
    {
    bubbles[i] = new Bubble();

    }
    }

    void draw() {
    background(0);
    for(int i = 0; i < bubbles.length; i++)
    {
    bubbles[i].move();
    bubbles[i].display();
    }
    }

    void keyPressed() {
    bubbles.splice(0,5); //here is the issue!!
    }

    ======

    class Bubble {
    float x = random(0, width);
    float y = random(0, height);

    void display() {
    stroke(255);
    fill(255, 0, 150, 50);
    ellipse(x, y, 24, 24);
    }

    void move() {
    x = x + random(-1, 1);
    y = y + random(-1, 1);
    }
    }

    after hours of trying how to figure this out i finally did it

    best part of this video is 7:33 purpose of life XD

  • comment-avatar

    I don't even notice how long these videos are, so helpful.

  • comment-avatar

    I'm having a really hard time understanding why you need the for loops in the example he uses. Why can I not just have the constructor function and the mousePressed function and that work? Why is the for loops a necessity? Why is the bubbles.length loop needed to have the mousePressed event work? Please help me understand this, someone. It's hard to look this stuff up on the internet and get a direct answer to my very specific question without someone here that can guide me through it.

    Amazing man learning so much with your videos. KEEP IT UP!!

  • comment-avatar

    You should make it so that every time you click, a new blue blob appears!

  • comment-avatar

    very informative. thanks

  • comment-avatar

    Thanks a lot, all your videos are very good. i learn a lot. 😀

  • comment-avatar

    Hi, Daniel, thanks for your videos. Im very enjoying with them. Here im trying to make some effect like, once you mouseDragged the circle, and with 1click , they will spread to random direction(out of screen). so, is there anyway to override the move() function of the constructor function of Bubble? thanks!

  • comment-avatar

    thanks dude ..

    u explain way better tha thos hindi vedeos i watched …

  • comment-avatar

    What library are you using?

  • comment-avatar

    i reaaly like when you use analogy to explain things because programming is so abstract, and is nice to come with a picture of what's going on in the program

  • comment-avatar

    For some reason mouseDragged does not work for me, although mousePressed works perfectly. Did anything change in P5 that prevents this from working? – It does work wiht mouseMove however, but that's not the same

  • comment-avatar

    hallo Dan , i can not download p5 !! why that ?

  • comment-avatar

    mouseDragged is not working for me
