Hello, I’m trying to set up a python node that only runs it’s script when a run button is pressed.

The only thing preventing me from making it work is that the button doesn't seem to set a 0 or 1 value for when its pressed.

I’ve tried setting status to 1 using hou.setenv("status",1)
and then read it in the script using hou.getenv("status")

But that didn`t seem to work.

Callback script
exec(kwargs.parm('code_py').eval());a()

Multi-line String
name: code_py
content:

Hello,
THis throws me the error

I’m also a bit confused, wouldn't I need to use.
('python') if I want to use the normal python script ?




Ps.

I whould think
whould be the propper formatting ?

If you just want one or a couple of run buttons and then some python code it is possible to simply attach this to a null. Probably you could attach it to any subnetwork or HDA as well (I've not really been trying this though).

If you need to set values accessible from any node, without keeping track of paths to nodes, you could do something like:

Hello i didn`t respond yet because I lost 1 month worth of work so I need to catch up for a while
I`ll be back though
