Thanks Daniel, you do great great stuff! Nature of Code is one of my favorite programming books period!

[@TheCodingTrain]

+David Ainley thank you!

[@KenzoArts]

I am only here for two reasons : 1. My teacher couldn't explain to me clearly what the heck are vectors and more importantly why should we care about them. 2. I love your videos it is so entertaining and fun to watch you explaining stuff in a simple way.

[@camsy83]

The 'processing skits' are what I'm tuning in for

I'm spending the new year watching Dan's videos instead of partying! Dan is probably the best teacher and the coolest presenter I've ever seen. You Dan are a gift to humankind, I salute your greatness my friend, may you inspire countless others as you did inspire me, and make this world a better place. I'm your greatest fan!

[@pdoopo34]

Just want to say, I found your channel a while ago when this series was fresh and it was this series of videos that got me here. I'm really happy to see just how much you've grown since then.

[@saimanoxiconfirmed535]

I dont think that this guy knows that he can cut a part of a video if something not planned happens

[@bobsherlock2589]

I think Daniel is very good but also this is very useful

[@beefytaquitos]

Imagine 100,000 people sitting in a stadium, watching these lessons. The internet is an amazing tool.

bro i love you a lot of support ily

Damn! you are energetic. I have not seen anyone who is this happy to teach. I want you to take this compliment as if I were speaking to you. "You are incredible and I hope to become more like you!"

Holy shit, his passion just radiates off him! He's a perfect teacher and just like,,,, wow! Hes so excited about everything! :D

You Sir are a great Human. Thank you so much for all the great tutorials. It has really helped me out, iv learned so much. 🙏

Dammit, I learned something! Wait, what was I supposed to complain about?

[@brunomeida1]

I am inside this camera looking at you. thank you very very much

[@sugarrush227]

and they said sixth grade math doesnt help you in real life

[@springbok4015]

Vectors were way after sixth grade for me.

Shcool: vector is arrow. Now learn how to subtract and add or else you get F.

[@rahulmathew8713]

This is exactly what we should have learned when we took Computer Science degree. How physics can be applied to simulate reality. Damn I just saw these videos after so many years since I passed by CS. I started my CS in the year 2007.

thank you so much, the explanation is great!

[@ryacdebarros1904]

Hi dan sorry this comment isnt really relevant to this video but your newer stuff is great. What books can you recommend for genetic algorithms and AI that are really worth my money or any other general books that are related to the type of code that you write. Thanks for all your help

[@islamguy2905]

So vectors are basically displacement.

[@UnbornFamas]

Hi Daniel, I have a question. How does Xpos being > than the Width or Xpos being < 0 cause the ball to bounce back I understand the code underneath does this however how does the Software detect the size of the canvas and bounce back? does the value drop to 0 on Xpos when the ball has traveled past 640 pixels?

[@TheCodingTrain]

Would you mind asking at discourse.processing.org/! It's a better platform for Processing and p5.js related code questions. You can share code there easily! Feel free to link from here to your post.

[@Fman261]

@WolfeyVGC

[@gerasimosmataragas353]

Hello Daniel! I am an architect new to processing and I started by looking at the tutorials at the processing.org page (I've reached until the objects tutorial). Now I found this series of videos however, I saw that you take some things for granted like the bouncing ball code. Would you recommend going back to the processing.org page to finish these tutorials before wathcing your videos or should I carry on?

[@TheCodingTrain]

I would start with these videos before Nature of Code: kzbin.infoplaylists?view=50&sort=dd&shelf_id=2

[@TheRemiRODRIGUES]

I guess the equivalent of PVector in P5 is p5.Vector, and the method createVector(x,y) ?

[@TheCodingTrain]

Correct!

[@tshichan]

it is my 5th time watching this video, and I still enjoy

[@lilystoddart3439]

this man is the bob ross of coding

[@filipemecenas]

Thanks

[@immaginariumworld1914]

how muche do you have to know about maths to learn coding? what are the basic of maths to know to learn coding?

[@TheRemiRODRIGUES]

It depends on what you want to do. It is not compulsory to know about maths to code some project, but it could be interesting to know about math if you want to create an optimize algorithm.

[@cybern9ne]

Just found this video series and I'm interested in using this with high school students. I just wanted to know if PVector() was actually a wrapper class for another java class or did someone code all the functions. For example, javafx has the Point2D class with all the same functions. I'm asking because I don't want the student to rely on external libraries.

[@TheCodingTrain]

it's written from scratch! Source code is here: github.com/processing/processing/blob/master/core/src/processing/core/PVector.java

[@CaseLogsTrades]

Dude you are in a good place. i go to sheridan for game design and our programming class uses his books

[@benjibluebird]

Why not represent the direction of the vector using slope?

[@danieloliveira9815]

you could represent it using polar coordinates (length and slope) but then you would have to convert it back to x, y in order to apply it to the 2D canvas that has x and y coordinates :P

[@jrayalac]

I love you Daniel

[@funtret12]

im kind of a noob on programming, if someone could respond x+= speedX; is equal to x = x + speedX;

[@Kstolen23]

exactly

[@funtret12]

+kris Stopher thanks !

[@lastskynet4346]

good job you help me god help you

[@gtpc779]

nice explanation :-)

[@ling6701]

Let's do this.

[@zoilo87]

Hello daniel pls give me the link where i could find the definition of pvector

[@TheCodingTrain]

processing.org/reference/PVector.html

[@zoilo87]

I mean the class itself.. Thanks dan

[@zoilo87]

Sir can i have a decompiler for PVector just to see the content within the methods into it??

[@zoilo87]

Thank you very much sir!! I hope someday i will soon meet you :)

[@rahulmathew8713]

The pdf explains the source code for PVector. Its supersimple

This is awesome, but yikes it needs a re-recording, vid quality is quite bad and audio out of sync.

I made it exactly 4 minutes and some change. Completely awful.
