[SOLVED] Issues with PythonScriptController

[SerkanErgunAAU]

Hi again,

I am using SOFA v20.12.02 with binaris (the “zip” version)

At the moment trying to set up an scene using SofaPython3, where I want to assign rotations to an object similar to this example:

Sofa-Framework PythonScriptController Example

For the sake of keeping things simple I am testing the code shown by @Hugo in the last post of the conversation.

When loading the file with my SOFA version using SofaPython3, I get the following error:

[ERROR]   [SofaPython3::SceneLoader] ValueError: Object type PythonScriptController<> was not created                                                           The object is not in the factory.                                                                                                                                                                                                                                                                                                                                                                                                                                                               At:                                                                                                                                                               robot.py3scn(182): createScene   
 

Theoretically, when putting everything in a single *.py3scn file it should work, right?

Consider the following very simple example

import Sofa
import os, sys
import math

def createScene(rootNode):
   rootNode.gravity=[0,-9810,0]
   rootNode.dt=0.001;
   ### Create a grid
   rootNode.addObject("OglGrid", nbSubdiv=50, size=1500)
   ### some other irrelevant code..
   return rootNode

def onBeginAnimationStep(self,dt):
      print("Hello world") 

`onBeginAnimationStep(self,dt):’ this part is never called

This is probably just a fault of syntax caused by my weak python programming knowledge.

I am very sorry to nag you again with my problems, but I hope for a simple remedy for this issue.

Kindest regards,

Serkan

Hi @serkan-ergun

Since January 2021, we moved to the SofaPython3 plugin which allow to use SOFA with python3 and from a python3.* environment.

Scenes are written in a slightly different way. You can find a list of examples in SofaPython3/examples/.

You can especially look at :
– basic.py
– basic-GUI.py
– example-scriptcontroller.py

Best

Hi @Hugo

Thanks. That was exactly what I was looking for 🙂

All the best,
