6.4: Variable Scope - Processing Tutorial

[@jessesmits3629]

Dude you're a born teacher! I've binged through lesson 1 up to lesson 6 in a couple of days. It's been a while since I've had this much fun learning. Please keep up the good work!

[@danielwatson6529]

same - thats a good few days :)

[@MrFrankenweenie]

It is really a pleasure to see you enjoying so much. It's contagious your eagerness for learning! Thank you so much for these videos!

i dont know if you can truly understand how lucky your students are

1:59 "well conceptually we have these concepts" I love him

[@paganteabreak7245]

Even if I had no interest in programming... I'm sure that you would make me want to grab a keyboard and start typing!! Love your natural style and humour... I actually look forward to watching your videos and firing up Processing :)

+Pagan Tea Break Blog/Podcast thanks so much, so glad to hear!

[@bubblebath2892]

Please update the 'Tags ' of this video to include 'global variable and/vs local variables ' because this video should be the first one a student should see while searching with these keywords- it's just awesome

[@diegoferreira3444]

global is a larger local, the best explanation ever. Also wanna see u juggle

[@kranefivem]

omg man its 6:24 in the morning, and i'm watching you from 10:27 morning last day, i love coding, and you my friend are the best teacher, you and my phisics teacher

This shit is helping me, a lot. thanks! Even though you did this a very long time ago. Greetings from Holland!

[@marianoceballos5939]

I saw these tutorials like one and half years ago, didn't even have processing installed then, now I started programming as a hobby / future job and It would never have been more easy if it wasn't for you, and I'm so happy watching this videos again, hoping you are doing the greatest now. ¯\_(ツ)_/¯

[@alpablo_1474]

One video on a day? I've seen 26 in a row :)

[@flomandile]

I am french and i love your video!

there are days that i do indeed only watch 1 video a day

[@ameychavekar5728]

u r my programmung god

[@kakuzu1233]

I needed this while learning the first while loop! Thank you :)

[@Ddmd1789]

Amazing video! I have to know though.. did you ever juggle and posted it on youtube? lol I'd love to see it!

[@viviancui9288]

Looking forward to the juggle!

[@shivankbatra5643]

lol . 5 mins ago only before watching this video i accidently declared a variable in for loop. and didnt declare it at the top nd i thought programme would not work!btw great stuff!plz reply toooooo!

[@j3226]

I'd love to see that juggling too! (I juggle as well)

[@sanderf13]

I don't understand why the code at 7:08 doesn't work. If x = 0 at the start it is less then width and it shoud execute the loop untill it's bigger then the width.

[@Anton-wc7lb]

[@bubblebath2892]

Same here , I didn't get why x should always start with 0 (even if its 20 = its still < width i.e 400)

[@NiLem98]

@Sander Van den Broeck @Anton @Bubble Bath Hey guys :) I don't know, if you figured it out, but here's the answer: background is redrawn after frame 1. Now the explanation: In the first iteration of draw() x is 0 at the start and 400 in the end. Now starts the second iteration of draw(), so the first thing that's done, is that the background is drawn, which means the lines from the previous iteration are gone. When it comes to the while loop x is still 400, so it doesn't even jump in there. So actually the lines are there for the first frame (which you can't see at 60fps, probably not even at smaller framerates).

[@sanderf13]

@@NiLem98 Thanks, initially i just moved on thinking it was just a 'processing-thing'

[@NiLem98]

@@sanderf13 Glad I could help :)

[@laurenmeenhorst8046]

Say you’re making a game with multiple screens. You need an x, y, width and height for multiple functions in each screen. Is it possible to localize your variables in each screen?

[@shakthivinaya]

I don't understand why it doesn't show output when x is declared global. Can you please explain? I see the while loop is valid the first time since x< width and shouldn't it keep looping till x= width to produce an output?

[@hispantrapmusic301]

[@Muhammed_English314]

A year late, but anyway. x becomes too big and the condition if false so it works for the first frame of draw() but never again, and the background (0) wipes it.

[@natalieheinze8715]

I need to build a Border so that my object won't leave the frame. I know about the bouncing ball, but how do I transfer this effect on two playable objects? I programmed a visibale border, but she is doing literaly nothing....

[@colemasuno5650]

I always laugh at your jokes. THANK U

[@rickperez8975]

Why is width and height not local

[@36degreesMars]

I actually do watch one video per day :P i''m THAT lazy

[@AntiChris]

"Isn't global just a larger local?" I cringed, lol.

[@2muchofyou]

dudes like the Riddler. hopefully without the murders ...

[@danielwatson6529]

only one criticism, you seriously need to work on your "pop-up" transition hehe - timing

[@zeldajerk]

You can speed it up. I find it amusing to see him hyperventilating and it definitely helps when it seems like it's a bit slow.
