When I use the extractor block it only allows me to extract the coordinates of the object itself. However, when I set it to “other” it just reverts back to its previous setting and doesn’t accept any changes to its settings if it involves extracting another object’s coordinates.
You need to select the object type and specific object too. Just the other type alone will not work.
Then reason that you need to select a specific object + the object type is because if you were to take the X cords of an object the engine would not know which object to take it from if there were multiple of that object
