Hello,

Can anyone help me get a word document, pdf file or website with a variables list. I am working with Houdini Master.

Thank you.

The built in help browser has all that info.

There are links right on the front page of the help. (Expression Functions)

hdox/houdini/content/commands/commands_and_expressions.html
hdox/houdini/content/commands/expressions.html
hdox/houdini/content/commands/guide/exp_guide.html
hdox/houdini/content/commands/guide/exp_globals.html

Hi,

You can use the Help Browser to search for what you're looking for. Search with these keywords: “global variables”, “expressions” and “functions”.

For functions, you can use the textport as well. Use the -k flag with help or exhelp. For example, you would like to search for functions dealing with distance:
exhelp -k distance
The above will return you functions that has the keyword “distance” in its help.

Hope the above helps!

Cheers!
steven

Thank you,

I am trying to figure out a rotation expression for a wheel (per frame).

What exactly are you trying to do? Do you want to rotate the wheel by a certain amount each frame? For example: one revolution -> 360/$FPS (FPS is frames per second). Or you're trying to know the rotation value for a certain frame? For exampe: ch(“/obj/wheel_object/rx”)

Please be more specific or post a simple hip file for others to look at.

Cheers!
steven
