when i try to add
var spot = {
x: 10;
y: 10;
};
to my code the whole programm stops working….
i got some problems with the variables which i declare…. i declared in setup/draw/outside all functions and sometimes the programm stopped working because of it … advise? not sure where to put my variables
Hahaha good tutorial i always happy see your tutorial video, usually people have to serious to coding but not you
"Oh look, some crazy stuff has happened here, some horrible stuff. This video is a disaster"
I have never seen a disaster in such an awesome way.
can somebody help me ;(
var xr = random(0, 600);
var yr = random(0, 400);
function setup() {
createCanvas(600,400);
}
function draw() {
background(0,0,60);
ellipse(mouseX,mouseY,20,20);
}
for(var i = 0, i < 30 , i++) {
ellipse(xr, yr, 10, 10)
}
dosent work when i put the random function
I could make it, hope you see this:
var spot = {
x: 100,
y: 100
}
var col = {
r: 100,
b: 100,
g: 255,
a: 200
}
function setup() {
createCanvas(400, 400);
background(0);
}
function draw() {
spot.x = random(0, 400);
spot.y = random(0, 400);
noStroke();
col.g = map(spot.x, 0, 400, 100, 255);
col.b = map(spot.x, 0, 400, 255, 100);
fill(col.r, col.g, col.b, col.a);
ellipse(spot.x, spot.y, 16, 16);
}
Man I´m Watching all of your tuition videos and all of them are great, you must be a great teacher. In the begining of the series when you introduce yourself I heard that you last name was Shitman and I thought, poor man such a bad last name for this incredible man, but then I realice it was Shiffman.
love this guy!
what code editing software would you recommend that's free?
i love the series man it inspired me to push through pursuing maybe computer science in the future
the part where u changed point to spot 6:32 cracked me up btw xD
love the way you explain it all 😀
Is it possible to use random(0, 255) inside the Color object for r, g, b? If so, how can I do it? I tried doing this and it's telling me the colors are undefined and I'm hoping that I wouldn't need to give color some dummy numbers and then override it with random later in my code.
If you would have been one of my teachers in highschool, I wouldn't have hated it that much. School is boring…
too much coffe…
Reference error: height is not defined
Same thing with width. Help?
I love this! It's great!
so perfect, much programming, such wow –
I learn more in your videos than I do in school most of the time. I absolutely love your videos and hope that my JavaScript knowledge and my python and partial Java knowledge will hopefully lead me to my career interest of being a software developer. Just wondering though, why do you always worry about the time of your videos?
I've been watching these tutorials serially but this one is cool. XD
Maybe we should make our boring teachers to watch this video and aware them how teaching should be done 😀
I wanna see your replies to some comments, why did you delete them?
hello great vids i have a question, how can you generate random ellipses one after another?
Man you are awesome !!
I made a cool shape_changer canvas :
function setup() {
createCanvas(screen.width, screen.height);
background(0);
}
function draw() {
frameRate(10);
//radius
var r = random(0, 255);
//color
fill(random(0,255), 0, random(0,255),50);
stroke(random(255), 0, random(0,255));
strokeWeight(random(0,4));
//different shapes
s = floor(random(0,3))
if (s===0) {
ellipse(random(width), random(height), r, r);
}
if (s===1) {
ellipse(random(width), random(height), random(0, 255), random(0,255));
}
if(s===2) {
rect(random(width), random(height), random(0, 255), random(0, 255));
}
}
These videos are great, thank you for making them! p5.js is so fun =)
I agree about keeping the issue in the video. Problem-solving is what programming is all about. And, it shows how even the most experienced coder can have simple issues like this. I can't say enough good things about your videos. Great stuff.
Wooooo Saaaaaa, Woooooo, Saaaaaaaaa 12345678910
P.S. Excellent videos by the way. I wish that I'd known about your channel when I got started. Not boring, clearly explained. Great refresher for people that haven't programmed in a while.
isn't this a bit POINTless?
"I've done something horrible! This is great!"
I love this. More people should approach learning in this spirit.
"And everything exploded, and i got a weird error message" lol xD
Hello Daniel
I´ve been watching your videos for a couple of days now and i was wondering how do you highlight your text in the editor ? For example the numbers are kinda orange.
Great videos you are helping me a lot.
Keep going
Hey. I created a simple file in p5.js but it won't work. Can I have some help and if so, where do I reach you to send the file?
P.S. I found your videos yesterday and I love them. You are amazing!
Embrace the Gay!
Why can't I set random when setting a var?
Eg, var spotrad = random(10,50)
Wow!! Sir, I'm enjoying learning with your style! It's AWESOME! It's Amazing!!
