This is such an encouraging course. " you can code anything you want from now on". So so happy for that!
Thank you so much Mr Daniel. Im just learning processing because i need it as a design student for my senior project which has interactive elements. Im already in the middle of the semester and your videos are giving me an amazing jumpstart to deal with this world of programming. You explain stuff brilliantly, keep it entertaining ALL the time, and constantly challenge your viewers and their imagination as well. You have perfected the art of teaching! :D Big fan here, keep up the great work :)
+Haleem ul Hassan thanks you so much for this very kind feedback!
A lot of respect for you Sir! I wish my university teachers could also clear all my concepts like this!
Wow, usually it takes me like 10 times to read something or listen to something so I can understand the problem. When I watch your videos I understand it immidietly .. this is amazing, you are an amazing teacher.
Watching your tutorial videos for learning processing has been a great experience. I appreciate that you give coding examples through a visual context, as I myself is more of a visual learner.
I´m been trying to learn how to code for a long time without any succes until now.
Thanks a lot, Daniel!!!! you are a great great teacher!!
I suffer a lot trying to understand what my professor does in class, and here I am, doing the programming class again, but now with this HUGE help that made me understand a semester thing in hours. RESPECT FOR THIS MAN.
I know I'm late to your videos, but you're an excellent teacher. Not only do you explain things very well and are able to show everything, but you're very relatable and charismatic which (obviously) is great for teaching. Thank you for your hard work!
I love your videos, Daniel. I have decided to study computer science at university this summer, and your videos really have helped learn about the basics of programming. Thank you
The only good thing going for me in my life is you, good sir. YOU ARE AMAZING! xD. Never stop these videos. Can you believe that thousands of people literally thousands even more around the globe is benefiting from this .
I really love how You teach. You make Learning so Easy and Fun. I enjoy Studying from You very much, and Your Little 'Jokes' Around (Like the pen...) Are very Sweet.
You are a marvellous teacher. So glad to have found your channel! 🙏🏼🙂🌱
I really like your lessons, certainly more interactive than the ones they pretend to drag at colleges. Well at mine. Love the way you keep it all unrefined, gives me kind of a comfortable vibe, wish we had teachers like you here. Anyway thanks for uploadin!
You made it!!!! I started programming with Processing3. Also the videos you have at www.processing.org are wonderful.
Great teacher!!
Thanks a lot, Daniel!!!! You are the boss!!!!!!
I've seen so many videos of you that I can just address you by Daniel and not Mr. Shiffman! hahaha We are buddies now.
Thanks a lot, for real.
+Javier Martínez de Velasco thanks so much for watching, of course you can call me Daniel!
AGAIN AMAZING VIDEO DUDE
KEEP GOING
THE CODE FROM THE LAST FEW SECONDS WHICH WERE TASK
float circleX=0;
void setup()
{
size(640,360);
}
void draw()
{
background(50);
fill(225);
ellipse(circleX,180,24,24);
circleX=circleX+1;
if(circleX>=640)
{
circleX=0;
}
}
Thanks for your coding lessons i wish i had a teacher like you
you're lovely! I've almost started to like coding. clear, simple and entertaining explanations, thank u!
+Valentina Ambrosi thanks for the nice feedback!
almost lol
great video!! thank you for your valuable contribution to the research. let me tell you something: you made my day.
I have jumped ahead early in this course and tried to use a for statement in the draw function with little success. I am beginning to understand the difficulties and found it much easier to use the if statement and managed to get the ball to bounce off each side by creating a variable that changed the increment of circeX from positive to negative (e.g. circleX = circleX + increment (increment changes from 1 to -1 alternatively)).
I was a little impatient with this course at the beginning but now appreciate that its structure lends itself to transferring skills to other languages. Many thanks. I struggled with trying to teach myself programming for years but have made rapid progress with your course.
first of all, thank you very much from these great videos
this what I have learned from these series of videos till this point.
// declaring variables
float paintball;
// setup making
void setup() {
size(800,400);
paintball = 0;
// background(50);
}
// drawing stuffs
void draw() {
background(50);
fill(255,0,0);
ellipse(paintball,200,30,30);
paintball = paintball + 1;
if (paintball>200) {
background(255,0,0,127);
fill(0,255,0);
ellipse(paintball,200,30,30);
}
if (paintball>400) {
background(0,255,0);
fill(0,0,255);
ellipse(paintball,200,30,30);}
if (paintball>600) {
background(0,0,255);
ellipse(paintball,200,30,30);
}
if (paintball>=800) {paintball=0;
}
}
thanks for your videos they are very helpful and extremely entertaining.
+Julian Santos thanks for watching!
thank you for all your videos!!
great classes .Would recommend .Sir is very ....jumpy
I wish that I found this series when I was trying to learn coding!
your videos are great keep them up please, saving my grade in university !
I actually do man ! any way we could hop on a quick private chat ?
I messaged you on facebook !
Your style of Teaching is Amazing
Love & Respect from Pakistan 🇵🇰
I love your work, and I also prefer the squeaky pen; something nostalgic about it. 10/10 more satisfying then non-squeaky pen
Thank yo so much, this course is wonderful.
Thank you for the support!!

YOU ARE AMAZING
know my concept is clear thnx
Tks. Daniel. Kool
this is not my first language maybe my 5th or 6th or so (i'm a senior studying csc and they all kind of get blurred after a while) but this video series is one of the most consice video series that i have seen on a programming language so far
Thank you for making vid like this would you make a machine learning vid too in processing
Thanks for the videos once again. I'm just happy that I've been able to keep up. This is fun. I cant wait till i get much better; i know its a long ways to go... but I'm persistent.
Can you do a tutorial on how to make programs into videos?
+Indigo Veilplume yes, this is a good topic! I'll add to my list: gist.github.com/shiffman/b9ab475922f82e8112ff
I figured out a way to do it with Adobe Premier and Aftereffects. Rendering with either would require some additional considerations that would probably be beyond the parameters of coding. It seems like everyone I've talked to uses ffmpeg- which isn't very user friendly for the beginner.
I think that having a clearer pipeline from coding to sharability would improve the attractiveness of programming for individuals who are less savvy with the technical details. Maybe that's something i can lend a helping hand towards when i have improved my understanding of the toolkit.
Thanks for your response. I look forward to the winter break so i can simmer with the text book.
float circleX;
void setup() {
size(640,360);
circleX = height/2;
}
void draw() {
background(50);
//Drawing stuff
fill(255);
stroke(255);
ellipse(circleX,180,40,40);
//Logic
circleX += 3;
if(circleX > 660) {
circleX = -20;
}
}
Nice video dude! ;)
+João Gamer PT thank you!
Is it okay if the the ellipse from the practice you assigned at the end loops?
Daniel...the name of the sign...is Lambda...and Antilambda. Greetings from Mexico
float circleX = 2;
void setup() {
size(640, 360);
}
void draw() {
background(50);
fill(0, 0, 225);
stroke(225, 0, 0);
ellipse(circleX, 180, 24, 24);
circleX = circleX + 1;
if (circleX == width) {
circleX = 640 - circleX;
}
}
Thank you so much, you made my day !!!
Good Evening Danilel ☻
Colors are fancy.
Can I ask a question here? I'm currently working on a project that uses ReActivision
and I've written a code that if I scan pattern A, I get video A
if I scan pattern B, I get video B
but if I scan pattern A and B at the same time, they both play simultaneously
what I plan to do is scanning pattern A and B at the same time can result in playing a 3rd video
in short, how should I implement statement that requires 2/multiple "true" checks (both id 1 and id 2 present at the same time) before it works?
this one is for separate:
if ( tobj.getSymbolID() == 1) {
theMov.play();
player1.play();
println("Play");
}
if ( tobj.getSymbolID() == 2) {
theMov2.play();
player2.play();
println("Play");
}
+Zero SSOX You can use an "AND", which is "&&"
if (condition1 && condition2) { }
This may be more complex based on your specific scenario, I would suggest asking this at forum.processing.org.
void setup() {
size(640, 360);
}
void draw() {
background(50);
fill (0, 255, 0);
ellipse(mx, 180, 24, 24);
mx = mx + 5;
if (mx > 640) {
mx = 1;
}
}
U r so Cute AND Humorous, don't know WHY.....
Love AND Respect from PAKISTAN.......
Sir please, I need help on how to increase player scores
Try this
PVector loc;
PVector vel;
Void setup () {
Size (100, 1000);
loc = new PVector (width / 2, height / 2);
vel = new PVector (4, 5);
}
Void draw () {
Background (255);
loc.add (vel);
ellipse (loc.x, loc.y, 24, 24);
if ((loc.x > width) || (loc.x < 0)) {
vel.x *= -1;
}else if ((loc.y > height) || (loc.y < 0)) {
vel.y *= -1;
}
}
i like the kind of weed u use !!
respect
in node? java? perl? c? c++? node.js? python?
If you need to program a rollover from scratch, you must first invent the universe. Or that's what Sagan would say. Sorry, I love you Daniel, thank you.
8:13
there is more than one right answer? he isn't saying to make it bounce off the right side, correct? Just to make it restart on the left side?
float circleX = 0;
void setup(){
size(640, 360);
}
void draw() {
background(50);
fill(255);
ellipse(circleX,180,24,24);
circleX = circleX + 5;
if (circleX > 600) {
circleX =20;
}
}
I'm in a programming class and I was so close to throwing my computer until I found these videos. Thank you for making this 10x more simple for my dumbass mind to comprehend.
More please make more vids please Sir
i tried to make the ball bounce back but i failed miserably haha but instead i made the ball nervous and shake rapidly haha
can you please help me, i need to write an if statement for my values.
for example im doing my project i am controlling values through a sensor the values change based on how hard i blow the sensor now all i have to do is add a if statement that if the value goes over 15 for example then it should play this video if it does not move from 15 dont do anyhting please help me
if(value > 15){
playTheVideo();
}
Let's call it a day
oh i'm crying it's sad moment
them pesky squeaky pens...
Yeah I Found the section
What about && and ||?
More complex
parenthesis✅ brackets❌
relational operators✅ data types❌
hahaha
if (circleX > width) {
circleX = 0;
}
circleX = circleX + 1;
Daniel
God i love programming a idea litteraly a stupid dumb idea can be made with peoblem solving
I had to put velocity video on 0.75
Hi me. My name is Paul Garrido i'm from Perú, i hace a son in Toronto need your help because he start study Computer system binaria for computer tecnician
I think 7 is greater than 7! but hey am not a computer.. HAHA!
Didn't know el professor from la casa de papel did programming.
I feel so sad for the circle :((
I wrote a program that ends so that the circle can rest in peace:
float circlePosX = 10;
float circleDiam = 20;
void setup() {
size (640, 340);
}
void draw() {
background(50);
circle (circlePosX, 170, circleDiam);
circlePosX++;
if (circlePosX > width - (circleDiam * 0.5)) {
circleDiam++;
circlePosX = circleDiam * 0.5;
if (circlePosX > width - (circleDiam * 0.5)) {
finish();
}
}
}
void finish() {
delay(5000);
exit();
}
Is this js
Java
His hands move way too much
