For those wondering why they can't see the attribute "test" in geometry spreadsheet is because in the attribwrangle node you need to set the "Run Over" to "Detail (only once)" and make sure you selected the "Detail" in the geometry spreadsheet.
WHY += instead of just +? I was struggling to understand the difference and the answer is: If you just say "sum + 2" you would perform that operation, but that wouldn't be stored into a variable. The only way to store it into a variable it would be to say: "sum = sum + 2" when you say "sum += 2" you are basically saying: Grab the value of sum and add 2 to it WITHOUT replacing the original value of sum. So you could keep using that original, unchanged value in the future. Hope that helps.
Just sad exemple are not in practice. I mean: used in a real situation for Houdini. But it must be complicated to make a big exemple for each code :( Thanks anyway !
Hey man, not sure if you're still active and reading the comments, but I'll give it a go anyways. I copied everything you did on this last example that you said was optional, but the only point that is infected is the original infected one that I added with "add" node. Can't figure out why and it's driving me crazy. If it means anything, I'm using 18.5.596 version.
Hey, it's probably too late for you, but maybe I find something which can help future people : Your attribute wrangle need to be on "Points" in the Run Over section. If you are in "Detail (only once)", the wrangle won't work.
Hello my friend, is it possible to return the Arabic translation of the video because it was not done correctly and I thank you for this wonderful content
3:36 I'm getting an error message when I follow this part when I create the " @test myArray[2]; " , but there isn't the same problem when I quote out that section and add " f[]@testArray = myArray; " , is it possible this is no longer supported in the current version of Houdini?
Is there a way to do an early stop, like using a return? That's a coding best practice rather than making a big if with all your code it in. Makes it more readable. especially if you end up with a lot of nested ifs. The doc only talk about return in a function context, so I am wondering if there is an equivalent for the wrangle context.
Hey, yeah, you can try using 'break;' it will break and exit the loop if it hits the break. Return can be used inside custom methods where you want a value returned or if you want to end the method early. Hope that helps😁
23:19 What is 'pt'? Why is there absolutely no documentation on this on the SideFX doc page and forums or anywhere else on Google that explains it??? 😢
Hey! It's a variable that only exists within the foreach loop. 'pt' is just the name of the variable. It can be renamed to anything you like. Basically, we are saying, for each value found in the given array, put that value inside of this variable called 'pt'. If you had an array of vectors, you could have something like foreach(vector vecVar; vectorArray){ } This would put each value from the vector array into the vector variable called vecVar (same thing as pt, just a different name) as the foreach loop runs I hope that makes sense!
@@NineBetween Looked high and low for someone who taught Houdini as well as you do and it's just you so far man! I can't thank you enough for this, the previous ones, the ones I've yet to watch, and all other future content you'll be putting out! 🔥🔥🔥
Great tutorial, Btw, Verse of the day: "If you confess with your mouth "Jesus is Lord" and believe on your heart that God raised Him from the dead, you will be saved. (Romans 10:9)
been working with code for years but can only read it and kind of work out what is going on.... seem to click with these videos and feel like every day I watch one everything falls into place and another 20 or so senarios are fixed with what you have taught me THANK YOU

Your method of teaching + speaking the keyboard commands are easy to follow. Thank you for sharing these videos.
No problem, I'm happy to help, thanks for the comment!
Great tutorial, as a beginner I'm learning a lot!
Why don't you do ""VOP"" Isn't Scary tutorial , Because VOP is really scary!
Thank you.
Please, do more tutoriais about VEX. This topic REALLY is complex 😅
Thank u for this. All The best.
WHY += instead of just +?
I was struggling to understand the difference and the answer is:
If you just say
"sum + 2" you would perform that operation, but that wouldn't be stored into a variable.
The only way to store it into a variable it would be to say:
"sum = sum + 2"
when you say "sum += 2" you are basically saying: Grab the value of sum and add 2 to it WITHOUT replacing the original value of sum.
So you could keep using that original, unchanged value in the future.
Hope that helps.
Can't wait to see the futur tut!
Just started learning Houdini and these and the Houdini isn't Scary series are absolutely amazing! Thank you so much, you rule
I love how you start off really simple then in the last 5 minutes you're like "Cool, lets just write a solver real quick".
Just sad exemple are not in practice. I mean: used in a real situation for Houdini. But it must be complicated to make a big exemple for each code :( Thanks anyway !
can you make an updated version of this tutorial? It seems that there are some things that aren't working properly in Houdini version 20

Same problem, can't fix!
works in h19.5

Really high quality course here. Thanks for posting to TH-cam!
you are a genius! 😎
Finally a easy to understand VEX tutorial! thank you so much!
Awesome series, but despite my code being identical in latest Houdini only the added point gets infected, it won’t infect others
great, reat, reat, very well explained, thank you

For some reason Its not generating any attributes in geo spreadsheet. I just followed the video as it is.
same
Best loops tutorial ever. Thx!

Ayyyy, Alvaro! Means a lot coming from you, I appreciate the comment man😁

missing "=" in your " @test myArray[2];" i believe
