NOOB ALERT!

Hi, folks! How can I learn function and expression and it's usage? Exhelp or Houdini help is a great tool but like I have encountered today and is encountering everyday finding right function or making the expression correct is a big issue for me. I didn't know what prim() does. Didn't know it actually exists. Then I saw some tut where everyone is using it, then went to exhelp and understood it. I hope you can understand my situation. So, how can I learn them fast or may be a direction to have them all? Here in Odforce or Sidefx many words are alien to me. How can I overcome it?

Please, if you can, share with me how you have learnt function and expression Thanks for your great help!

you can just read the help, there is not so many of them
and once you read the description it may make sense to you how to use it

http://www.sidefx.com/docs/houdini14.0/expressions/ [sidefx.com]
as well as VEX
http://www.sidefx.com/docs/houdini14.0/vex/functions/ [sidefx.com]

at least that's how I learned them, occasionally scan through function lists in new versions of houdini to discover new functions that usually can save lives
it's much faster way to wait for some file or tut to come around that is actually using them

Huge Thanks! These lists are quite good with detailed instruction. I am going to take a look at that right now…

Also look at the expression cookbook in the help.

http://www.sidefx.com/docs/houdini14.0/ref/expression_cookbook [sidefx.com]

It has examples of some of the expression functions on simple input geometry.
