Python Reference For Parameters And Arguments

[Andz]

I'm trying to learn some python scripting for H.

frame = geo.createNode('circle')
frame.parm('type').set('poly')

It took me a while of trial and error to find out that the argument for the circle type was "poly" and not "polygon", etc... Is there a reference somewhere about all these parameters and arguments ?

Thank you.

I don't think so... what I do in such a case is that I call eval() for a parameter in question to see its current value. This way I'm sure about the token.

cheers,

sy.

EDIT:

upss... not true actually, sorry. Tokens work for hscript only...:

opparm -d circle1 type

In python you get menu item's index from eval():

mynode.parm('type').eval()

-> 0 for prim

Nevertheless both methods of investigations work well

Hi SYmek

I don't know if I understood you well. As you can see in the video attached, eval was giving me numbers (0,1,2,etc.) not the Argument

But while I was trying it out, I found the list of tokens... check it out in the vid ;-)

***edit*** Oh, got it now... I can also use its index number for the token, both lines would work:

hou.node('/obj/geo1/circle1').parm('type').set(1)

or

hou.node('/obj/geo1/circle1').parm('type').set('poly')

yep, all is clear now. I've just wanted to point you out that in case you look for a token, index number could help

glad you solve the problem,

cheers,

sy.

Thank you Sir!

My please, but you helped your self actually

good luck!

Continuing exploring python...

I'm creating a PolyBevel node and adjusting some parameters:

bevel = geo.createNode('polybevel')
bevel.parm('group').set('p5-1 p5-4-0 p4-7-3 p7-6 p5-6-2')
bevel.parm('beveltype').set('lowround')
#bevel.parm('setinset_1').set(True)
bevel.parm('absinset').set(0.019)
bevel.parm('repetitions').set(2)
bevel.setFirstInput(instance)

On line 4, I'm trying to turn on the Absolute radio button, but I get a message that there is no Set attribute.

I thought that only by adjusting the absinset value would be enough to switch it on, but I was wrong.

** Edit ****************************************************

I got a hint from SYmek's post on another thread:

hou.node('/obj/geo1/polybevel1').asCode()

In it, I found out that the parameter name listed is deferent than the actual parameter used in the code. That line should look like:

bevel.parm('setinset1').set(1)
