I stood up and applauded
The reason these videos are so good is how genuinely excited you are about this stuff!
and they're clear and informative.
"This has nothing to do with arrays, but I can't stop!"
This is why I watch your videos. 😂
Daniel, which function did you write to make yourself invisible at the end!?
You think you are mumbling, but that mumbling is an interesting fact to me and knowledge. Thank you for making the videos.
I am currently learning processing at the University of Oklahoma as part of the Master's of Art and Technology program. Your videos and book (it's our textbook) is INVALUABLE! Thank you for making this easier to understand.
I'm so happy to hear this, thank you for the generous support!
You make learning to code entertaining and fun. Thanks for being you Daniel!
Thanks for watching!
Best teacher in the world, he makes it totally worth to watch this video.
These videos give me a reason to learn Processing. They're fun and informative. I always laugh and learn something new every time.
I am sorry, I don’t have to pretend to be excited or happy while watching your video. I am already happy and excited for every video.
Love your work dan! Best coding course I have ever done!
You're a great teacher, I've struggled for the longest time to understand what an array is and how I use it to display objects from a class I've created and just within like 15 minutes you've managed to make me understand. (this vid + last vid)
Hell, I understand the practical use of a for loop too now. (Before I didn't even really understand when or where to use one, I did kinda understand and use while loops though.)
Thank you so much.
Bro got me excited to see 1000 bubbles and actually smiled when I saw it, I was so happy😁
Thank you so very much, you just by teaching the way you have contributed to humankind, and saved me from utter frustration. So it is with deep seriousness that I thank and congratulate you. Cheers!
finally found what i was looking for the last whole month
your the coolest teacher ever. swear.
I'm excited because I think he's about to create a ton of bubbles
Yay! I was right
@@corey333p Lol
Thanks, been struggling with how to comprehend arrays and this helped a lot
Very nice channel Daniel, for a beginner in Processing this is truly gold mine ! My only regret is I tried by myself finding the answers on google before going through all your tutorial. I would have saved a lot of troubles watching this first ^^
This is a true shame you got so few viewers because you have this way of explaining with a nice touch of humor =)
Btw I loved how everything felt apart hardware side at the end of the episode xD
+Furrane Glad to hear, thank you!
I've been trying to write a code with an array and A loop..... What did I do... go to google... and what happened I FAILED
The way of teaching is simply awesome.
Thanks brooooooooooo
" im excited " believe me!! * :)
also this guy is a cure for depression too!!! what a sensei!!
Thanks for the p2d and p3d knowledge! I never knew about these before
flipped my desk at 7:00
Luis Alonso Sandoval Gomez I flipped it at 11:24
OH YEAH! I flipped my phone at 00:01!
He even disappeared at the end. True code magician.
Wow, you explain it wonderfully
WHY CANT YOU BE MY TEACHER , EVEN BETTER MY OLDER BROTHER
this is so helpful! thank you so much
You are incredible sire
got a 100 in my class because of this mans
"edit the last minute out" seems like that never happened, but I'm not disappointed.
bro is crazy and its brilliant
you just saved my exams:)
Awesome, I love you!
Great video just a quick question can we use for count loop? I hope
you're familiar with it
ur way is soooooooooooooo awesome
Every Video starts: "We're close now we're close, trust me"
Hey The Coding Train, how can I make this array bubble react when they collide? I can't find a way to distance an array bubble form another cause they are all [ i ]. Thanks love the channel.
How do your glasses effect the greenscreen image ????
does anyone know what video it is where he creates the function bubbles?
How do you initialize a variable to have a different value depending on what class array its in (meaning class[0], class[1], class[2])
This was in Processing 1... Holy crap Daniel :)
Some of these videos are quite old!
If I apply random values to xspeed and yspeed then theres no wall collision detection in that direction. If I apply random to xspeed then I have a bunch of balls bouncing up and down and vibrating randomly side to side but they leave the screen eventually to the sides. Having less than 30 makes it obvious that they r leaving x=0 And x=width. Why does random do tht how can I prevent this?
awesome channel! :) but how do you make the bubbles keep on comin? for example i got an array with 10. they are comin but only once ?!
+AVNU you'll probably want to use an ArrayList. th-cam.com/video/HnSJZ4qTcwY/w-d-xo.html
I really tried to catch up the following link. But it was extremely difficult. I really don't get the link..
Can I ask you what I didn't get from that?
quick question. Is there a way to choose between two 2d arrays? For example:
If( button 12 cards is clicked )
use the array 1;
if (button 14 cards is clicked)
use array 2;
hi daniel so im having a problem working with arrays so far, im trying to combine object arrays with a bouncing ball object, im trying to make it to where when the balls collide they change directions and each get a separate fill color. ive gotten everything working so far, but when they collide for some reason only one changes color no matter how i change my code. any suggestions or would it help if i could post my code somewhere?
I would suggest posting your code at forum.processing.org, thanks!
try posting code at forum.processing.org
which editor do you use to make programs..
plz tell
See processing.org
Hi Dan, Thank you for making these tutorials, just want to ask you, how can I fill each one of the bubbles with different color? I tried to add fill under display function, but the result is all the bubbles flash with different colors again and again.
Try This .
Tab1
Bubble[] bubbles = new Bubble[1000];
void setup(){
size(640,360);
for(int i=0; i
Thanks Prithvi! This is great! Can I ask you questions again if I have any problem in the future?
@@banli8262 Sure!!
@@prithvimadugula1993 i cant seem to find ur reply do you mind sending it again?
Can you make a programm in which four consecutive rectangle of 90*90 move together and stop when key pressed. Size (360,360)
No of the triangle should be decreased as it move further.
how'd I make it so that the bubbles would not overlap each other?
that is good!
hey.. Have you done any videos on Recursions? curios to know.
+Neha Singh Take a look at these! th-cam.com/play/PLRqwX-V7Uu6bXUJvjnMWGU5SmjhI-OXef.html
I came here to Clear my doubts about arrays but stayed here untill he gets 1000 bubbles🙂👏
Please how did you make the bubbles reset and start at the bottem
i made my code like you did but all bubbles moves in same place ????
Great video, but when I included the P2D parameter in the size function, it actually slowed down drastically! Just wondering if I'm the only person who experienced that?
I don't get how u got two different x values with the constructor argument. the other tab is not open?
Hi sir would you please upload a video about how to use clamps pleaseeeee
Thanks!
Thank you for the support!
Im a very late watcher to your videos and i would like to know which video you made to make the code for the Bubble tab at 5:41.
Also your very (how do i say) Like my ADHD, very energetic and at times random (^ - ^). I really like it.
Daniel, The Code for the Bubble class(2nd tab) is not available, please upload the code, I look in previous videos but it is different. Thanks.
I'm excited too to create a ton of bubbles...
which software you are using for coding, sorry i didnt watch your first videos
This is processing.org/
PLEASE HELP!!!
How are you getting them to continuously appear, I have an array list that results in multiple objects to fall down the screen, but when they leave the screen more don't come. How do i get another wave to come?
I hope this helps. It's the code for the Bubble class I made for this example. They go up instead of down like in the video, but if you look at the "top" function I have, hopefully it will help you get an idea of what you could do.
class Bubble {
float x, y; // position
float yV; // speed of bubble
float r; // radius of bubble (diameter / 2)
Bubble(float tempR) {
r = tempR;
x = random(r, width-r);
y = height-r;
yV = -1 * random(0.25, 4);
}
void display() {
stroke(0);
fill(127, 63);
ellipse(x, y, 2*r, 2*r);
}
void ascend() {
x = x + random(-3, 3);
y = y + yV;
}
// Here's the "top" function:
void top() {
if (y
@@HectorialInfection why does it say that width cannot be resolved to a variable?
bubbles[i] = new Bubble(64) ;
shows me an error that the class Bubble isn’t defined
Dan how did you become invisible? lol! 11:26. Regards from Argentina!.
Magic! Thanks for watching.
I love how you pooped like a bubble in the minute 11:25
Never seen bubbles poop
never seen bubbles p- oh, someone else said it already
I constantly get a NullPointerException and can't solve it. Does anyone know how? I used the same code as in the video.
I see bubbles everywhere in my mind.
You didn´t show the entire class Bubble in the video
NullPointerException?
5:18 you should change 2nd loop not to 20 but to length od array
Edit: OOPS i just noticed you did it. 🤣
0:49 you always do xD
what if you want to push away the balls through mouse clicks? Thanks!
+Luis Vasquez You can use a "repulsion" force. I cover this concept in my Nature of Code video series: th-cam.com/play/PLRqwX-V7Uu6ZRrqLcQ5BkBKmBLiGD8n4O.html
How do I open the lid of a box through a mouse click, counterclockwise and 180 degrees?
and by mouse clicks i mean a button on the side. That button opens the box and changes the color of the box. Once it is clicked again, the box closes
like this
dl.dropboxusercontent.com/u/4181195/HatchDemo.mp4
+Luis Vasquez There are a lot of pieces involved in a problem like this. You can look at conditional statements and boolean variables for the button, you'll need to investigate translate() and rotate() for the box. I might suggest starting a thread at forum.processing.org for further discussion.
Now do it in 3D and make them coalesce 😅
BUBBLES!
1000 bubbles = foam
Jajaja, you disappeared!
P2D ;) !!!!
P3D ;-) !!!!!!
