get object in the scene using `ObjectID` #108

Hi! Sorry for repeating the same question, but I still have it after the closing of my previous issue.

In the answer you have mentioned that the ObjectID attribute uniquely defines the object in the scene. But how does it work exactly? The ObjectID string is quite different from object identifiers in original Unity scenes and I need to get the exact correspondence between the objects in the task and the assets in the scene.

Thanks for your patience!

@nikita-petrashen, just to be clear here: the ALFRED dataset is based on the Ai2THOR simulator, which is an executable binary that is interfaced through python. We basically treated this binary as a blackbox without know much about how it works underneath – including how ObjectIDs are instantiated. So you will have to check here: https://github.com/allenai/ai2thor

Thank you for understanding!
