Hi guys

I have a python SOP with a few things on it,
all those things are different functions that I want to
trigger with buttons, so how do I do it?

I know that in a regular HDA I use hou.phm().hello() for example

but for the Python SOP that doesn't work cause the code is NOT in the
same place.

see the image as an example
clicking the button will run hello() function

THanks

The code section is not like the PythonModule: you cannot call functions from it. You'll need to put your code in the normal PythonModule to be able to call it from a callback.

I'm messing with geometry so I need to do it this way

right?

cause the other way it's gonna complaint that the geometry is read-only

any ideas?

thanks

If you have a parameter-less node like this, then your Cook button can simple force a cook of the node (eg. opcook -F .) and it'll execute the entire Python code section. I assume you are making a no-input “generator” type SOP. Any parameters you create on the node will also trigger a cook of the node.

the thing is I want to have 2 buttons

one executes a function
and the other one does another function

thanks

Parameter buttons should not modify node data. They should just modify parameters. Forcing a recook should not even be needed because whoever needs the data (eg the viewport) will just naturally recook after the callback finishes.

I have nothing to add, just second all above. Code section is not going to work with the buttons since it is cooked every time. I'm not exactly sure what you heading for but perhaps what you want to do is to split Code section into several separate python sops embedded inside parent HDA with all the ‘trigger’ functions…
