Editing Parameter Interface with Python

[RuschFX]

I'm writing a python script that populates geometry nodes and edits each node's parameter interface, and I've ran into a few problems. I'm new at python so forgive me. I have been able to create new folder tabs and populate them with float parameters fairly easily. This is what I used to create one of the float parameters......

partTemplate = hou.FloatParmTemplate("timeOffset", ("Time Offset"), 1, default_value=([0]), min=-10, max=10, min_is_strict=False, max_is_strict=False, look=hou.parmLook.Regular, naming_scheme=hou.parmNamingScheme.Base1, disable_when="", tags={})
hou.node('/obj/geometry1').addSpareParmTuple(partTemplate, in_folder=([character1]), create_missing_folders=True)

The problem is I also need file and integer parameters....... The commands I'm pretty sure I need are hou.FileReferenceParmTemplate() and hou.IntParmTemplate(). I can't get them to work and the help says they haven't been implemented yet!? Can anybody hook me up with a script example of how to successfully add these parameters or know of a work around? Thanks in advance for any help your able to give......

ok..... just shortly after I posted this, I ran hou.asCode() on a node I manually built and figured out how to get file and int parameters to work. So I figured I'd share, incase anybody else has run into this problem....

#MAKE A GEOMETRY NODE
curNode = hou.node('/obj').createNode('geo', 'character1')

#CREATE INT SLIDER IN PARAMETER INTERFACE
timeTemplate = hou.IntParmTemplate( "timeOffset", "Time Offset", 1, default_value=([0]), min=-100, max=100, min_is_strict=False, max_is_strict=False, naming_scheme=hou.parmNamingScheme.Base1, disable_when="", tags={})
curNode.addSpareParmTuple( timeTemplate, in_folder=([spareFolder]), create_missing_folders=True)

#CREATE FILE REFERENCE IN PARAMETER INTERFACE
fileTemplate = hou.StringParmTemplate( "fileIN", "File Input", 1, default_value=(["0"]), naming_scheme=hou.parmNamingScheme.Base1, string_type=hou.stringParmType.FileReference, disable_when="", tags={})
curNode.addSpareParmTuple( fileTemplate, in_folder=([spareFolder]), create_missing_folders=True)

Also, it's easy to create a new folder in the parm interface, but it puts it after the default tabs. Does anybody know how to move it from the last tab in the group to the first??? (ie. before the "Transform" tab...)

Thanks,

I have a python code which have a loop to get alembic files path from a dictionary and now i want to add a new parameter for each alembic path in a specific node according to loop count using python. can anybody tell me how can i do that.

newbie to python and houdini

Untested, off the top of my head:

node = hou.node('your_node')
ptg = node.parmTemplateGroup()
for i, file_path in enumerate(paths):
  pt = hou.StringParmTemplate('file%d' % i, 'File %d' %i, 1, file_path)
  ptg.addParmTemplate(pt)

node.setParmTemplate(ptg)
  

Or you could multi-parm block: hou.FolderParmTemplate( ... folder_type=MultiparmBlock)

I could do it as you said with:

In my case I used:

for i in range(1,20):
...     new_folder.addParmTemplate(hou.StringParmTemplate("parm"+str(i), "Label"+str(i), 1, default_value=([""]), naming_scheme=hou.parmNamingScheme.Base1, string_type=hou.stringParmType.NodeReference, menu_items=([]), menu_labels=([]), icon_names=([]), item_generator_script="", item_generator_script_language=hou.scriptLanguage.Python, menu_type=hou.menuType.Normal))
... 

But, do we really have to use that full line of code?

Is there a shorter reference to call an "operator path"?

Thanks
