no hou.selectedParms() ?

[lemond]

I'm looking for a command to return selected parameters.

Example, user selects ch("obj/box_object1/rx") and ch("obj/box_object2/rx")

hou.selectedParms() would return those selected parameters.

What is the best way to do this?

There is no notion of selected parameters in Houdini so I'm not sure what it is you are asking for. The only ways to interact with parms are to either have callback scripts assigned to parameters, or add some type of entry in the PARMmenu.xml file to allow you to do things to parameters from the RMB menu. I'm thinking the later is in the direction of what you are after but I can't be certain without more info.

Here is my code. But, I want to avoid hard coding the parameters. I don't want to add another read input.

import random

min = hou.ui.readInput("Enter Min Value")
max =  hou.ui.readInput("Enter Max Value")


min=float(min[1])
max=float(max[1])


def randomizeParmValue(node_list, parm_name, min, max):
    for node in node_list:
        value = random.uniform(min,max)
        print "parm to change %s at a value of %s" % (value, parm_name)
        node.parm(parm_name).set(value)


selectedNodes = hou.selectedNodes()

#hard coded parameters
randomizeParmValue(selectedNodes, 'tz', min, max)
randomizeParmValue(selectedNodes, 'ty', min, max)
randomizeParmValue(selectedNodes, 'tx', min, max)

[/code]
