Add list of strings to parameter interface

[Mark01]

Hi All ! 

 

So I have an array of strings. Each string is a character_name in the scene, the array is therefore listing all the characters in the scene. 

I would like to list all the characters in the scene in the parameter interface of a Null node. 

 

So my questions is, how do we take array data and list it in the parameter interface of a null node?

The number of characters in the array changes too. 

 

I really can't seem to find any information about this anywhere so any ideas would be really useful! 

Thanks

Hey Mark !

I assume your null parameter interface is a multi-parm block.
The idea is, in Python, to set the multiparm block number to the amount of items of your array, then for each items of your array, set the string parameter for the character name.

geo = hou.pwd().geometry()

characters = geo.stringListAttribValue("characters")

hou.parm("../UI/characters").set(len(characters))

for i, character in enumerate(characters):
    parm_name = "../UI/character_{}".format(i)
    hou.parm(parm_name).set(character)
