Houdini Guide, dealing with expressions Dec. 10, 2017, 3:27 p.m.

Cyzor, I will certainly check out the info on Odforce on vex and hscript and
AndyW thanks for the inspiring words, I really like the Cookbook idea. I get really frustrated with the program sometimes , but the whole principle of Houdini is just so amazing, so I wound give up.

Houdini Guide, dealing with expressions Dec. 7, 2017, 12:26 p.m.

Hello Forum,

I have a stupid question. I study animation using Maya and I also do modelling in Zbrush.
Now I like to go even deeper into Computer Graphics by learning Houdini. I started out with a Houdini 101 course on Lynda and also did a ton of tutorials. Now I'm reading the Houdini guide on a day to day bases. Most of what I'm reading I understand, other thinks a bit less, but when it comes to Expression functions, HScript commands and Vex I'm lost.
The explanations in the Houdini Guide for each function don't make sense at all. Often I google the words I don't understand and I get sends to a wiki page about some math subject, which most of the time doesn't help.
It's for certain my problem is a lack of the English language, coding and math in general.

So my question is, how do I overcome this obstacle? I'm already doing a course on coding and math on Khan Academy, but maybe there are other ways dealing with this problem, especial when it come to programming inside Houdini.
In the near future I like to develop my own concepts and work them out inside Houdini. I don't want to rely on tutorials any more. Most of the time they don't explain what is really happening underneath. So if you got any suggestions dealing with this dilemma, please share.

Dynamic Object Position Parameter Nov. 22, 2017, 12:41 p.m.

Good evening,

I have a question.
So, I have a dynamic object effected by certain forces,
and I like to copy the position from the dynamic object to another object.
But I can't find a parameter that could give me the position of the dynamic object, while running a simulation.
Is it possible to use the dynamic object position, as reference in real-time?


My goals is; every time a dynamic object comes close to a certain object, the object starts move, pushing away the dynamic object.

I'm very new in Houdini, so maybe I'm overlooking something important.
