Python code: Selecting all objects with one attribute

AlexWierzbicki

Hoping that someone can help me out. I am a python newbie and I am trying to create a script that will select all objects that have the Object Attribute "amenity" equal to "school". Could some please help me identify what is wrong with the below code? 

from scripting import *

# get a CityEngine instance
ce = CE()

def selectByAttribute(attr, value):
    objects = ce.getObjectsFrom(ce.scene)
    selection = []
    
    for item in objects:
        attribute = ce.getAttribute(item, attr)
        if attribute == value:
                selection.append(item)
        
    ce.setSelection(selection)

if __name__ == '__main__':
    selectByAttribute("/ce/geometry/amenity", "school")

hi again,

• @noUIupdate needs to be directly above the function you want to trigger no UI updates
• change the filter in your getObjectsFrom() from ce.isGraphSegment to ce.isShape. Amenity is isuallay a object attribute assigned to shapes.

I tested the the code below, and it works for me:

# get a CityEngine instance
ce = CE()

@noUIupdate
def selectByAttribute(attr, value):
    objects = ce.getObjectsFrom(ce.scene, ce.isShape)
    selection = []
    for item in objects:
        attribute = ce.getAttribute(item, attr)
        if attribute == value:
                selection.append(item)
    ce.setSelection(selection)

if __name__ == '__main__':
    selectByAttribute("amenity", "school")
