python code in a shelf buttom

Recommended Posts

Hi, I am new scripting for Houdini

I made an script in python, I tested on "python source editor" window... it works

So I decide to make a shelf buttom in order to store it and apply it later on.

I put my code into the script tab and field, define python as my language.

but when I click in my buttom, it says this error message:


Traceback (most recent call last):
  File "tool_1", line 7, in <module>
  File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.499/houdini/python2.7libs\hou.py", line 50447, in keyframes
    return _hou.Parm_keyframes(*args)
ObjectWasDeleted: Attempt to access an object that no longer exists in Houdini.


this is my code

import hou

for n in hou.selectedNodes():

    for p in n.parms():

        if len(p.keyframes()) > 0:
            exp = p.expression()
            exp = exp.replace("L_", "R_")


what I did wrong?


thanks you

It works for me, but the error tells you what is wrong. A node in the selection was removed somewhere during the process. Try testing to make sure p is not None before trying to fetch the keyframes.
