New Condition Naming in Attribute Manager

[d_schmidt]

Hello, I noticed there seemed to be a new 'name' feature with the Condition object.

Is it possible to make use of it in a plugin?

'Condition' is just the object's Name, but I can't figure out how 'distance' is set.

Hey @d_schmidt,

Thank you for reaching out to us. That feature has existed since Pyro was introduced but at the same time it is also an internal feature, i.e., a feature of which we publish the components, but which we do not support in public usage. To realize a node which supports name additions, you must register it with the flag OBJECT_CUSTOM_NAME_ADDITION:

RegisterObjectPlugin(ID_MY_PLUGIN, GeLoadString(IDS_MY_PLUGIN), otherFlags | OBJECT_CUSTOM_NAME_ADDITION, MyPlugin::Alloc, "omyplugin"_s, nullptr, 0);

Reading or writing to the custom name is then realised via the node message MSG_GETCUSTOM_NAME_ADDITION. I am showing the write access in C++:

Bool MyPlugin::Message(GeListNode* node, Int32 type, void* data)
{
  ...
  switch (type)
  {
    // Something, for example the Object Manager, wants to know the addition to the name. The 
    // message data is just an empty string. The plugin should return the addition to the name.
    case MSG_GETCUSTOM_NAME_ADDITION:
    {
      *reinterpret_cast<String*>(data) = "Hello World"_s;
      break;
    }
    default:
      break;
  }
  ...
}

And since nothing is safe from @m_adam , I just found out that he wrapped the reading part for Python (cannot see the writing part handled in Python). Since you cannot cast arbitrary data in Python, we must use a dictionary as the data container.

Cheers,
Ferdinand

Thank you so much! I couldn't ask for a more thorough response.
