Getting the id or name of the newly spawned prop through PythonAPI

[MasoudJTehrani]

Hello everyone,
I used the PythonAPI to spawn a prop, namely, the "static.prop.ironplank". How can I then get the ID or the name of the prop in my current world?

I used this code:

names = world.get_names_of_all_objects()
    for n in sorted(names):
        print(n)

and manually searched through the values and found that my prop is called "StaticMeshActor_2147479215".
How can I do it without manually searching through the names of all objects?

This is the code that I used to spawn the prop

prop = blueprints.find('static.prop.ironplank')
    location = carla.Location(x=80, y=108, z=7)
    ts = world.try_spawn_actor(prop, carla.Transform(location))

and if I print ts I get:
Actor(id=26, type=static.prop.ironplank)
Which is not what I am looking for

Hi,
what do you want to do with that information?

If you want to spawn an actor and find the actor instance at a later time, you can use the "role_name" attribute.

client: carla.Client = carla.Client("127.0.0.1", 2000)
world: carla.World = client.get_world()
blueprints = world.get_blueprint_library()
prop = blueprints.find("static.prop.ironplank")

prop.set_attribute('role_name', 'hero')
ts = world.try_spawn_actor(prop, carla.Transform(location))

# at  later time

actor_list = world.get_actors()

your_actor = None
for actor in actor_list:
    if "role_name" not in actor.attributes:
        continue
    actor_role: str = actor.attributes["role_name"]
    if actor_role == "hero":
        your_actor = actor

It used role_name with vehicles, but it should work with all actors.

Hi,
I want to then change its texture using
world.apply_color_texture_to_object('StaticMeshActor_2147479217', carla.MaterialParameter.Diffuse, texture)
and unfortunately, your solution is not applicable in this case.
I guess I have to either use UE editor to change its name or just look for a StaticMeshActor that has the longest number in front of it.

Hi,
you could look in the actor.attributes if the object name is included, or maybe it is somewhere else in the actor.
I would need to check the actor class myself to be sure.
