[VEX for Algorithmic Design] E11 _ Dictionary Basics

This is a new series I've started explaining the basics of VEX for algorithmic design / procedural modeling which I'm using on daily basis.
In this 11th episode, I'm explaining the basics of a dictionary which is a new data type introduced from Houdini 18.5, how you can use it with little bit of examples.
I've also started a Patreon, it would be great if I could get your support to continue creating tutorial contents.

Thank you. Moving to houdini from a regular 3d package feels like you've been playin with legos to build things, and now you can shape the atoms of said things. It's a paradigm shift. Your videos help ease the transition. Thank you so much. It feels like vectorfield landscaping.

[@herbertengels2112]

Thank you so much Mr. Junichiro. I hope you make more Vex videos. They are really awesome.

[@guitoma109]

Thanks Junichiro, fantastic tutorial as always. Lets go to the next JuniFlix serie Vector.

[@eggZ663]

Great tutorial and great teacher!

[@arsensuleymanov7935]

Thank you. Amazing. Will try to understand how to use them in practice.

[@izvarzone]

Is it more optimized than run 4 cycles for different attributes?

[@dorincroitoru5913]

so powerful. thank you!

[@raneemFX]

Thanks yor legend

[@requa3314]

thank you so much !!!

[@esoyychen3527]

Thx!! I was curious about how to use loops to traverse the dictionary and use key functions. I kept showing syntax errors in my tests.

[@sasanarian132]

thank you bro

Must of updated Dictionary for H19.5. My spreadsheet doesn't show the data "type" etc just the values e.g. {"a", 3.0, "b", 6} and that's it. Guess it saves a lot of room 😀

[@stevensilcock]

@1:14:17 json_dumps fixed it, now I see all the data info in spreadsheet....noice.

[@AncienRegimeStudios]

Another excellent tutorial. One problem; how do you view a long Dictionary in the Geometry Spreadsheet? There's not even a slider to let you go to the end of the Dictionary. Thx

Houdini 19 now has an "Inspect" right click function (Extremely handy for nested dictionaries. It shows them hierarchically, as a tree)

[@c.e.l.l.z]

Another thing you can do is: in geo spreadsheet pane; go to the View dropdown and toggle Typed Dictionaries. You usually won't need the tags anyway.

[@chriswong225]

one question. I would like to get dictionary items() like python to do the operation. it only have keys() function in vex, when I forloop each key to get the value, it does not know the key's data type. then I cannot get the value auotmatically if I do not know the type... May I know how to do it? maybe I need to swiitch to python to finish this task... Sample Below: string keys[] = keys(d@data); foreach(string key; keys) { [type] value = d@data[key];

[@chriswong225]

Solved in python. But It’s quite slow and not able to compile… hope found the way done it on vex….
