******* Objects ******* Environments in VirtualHome can be populated by multiple objects, including appliances, furniture, decoration pieces, etc. There can be multiple 3D models for every object type, which are called `Prefabs`. The file `PrefabClass.json `_ contains a mapping from the object names to all the prefabs representing this object. You can find the dimensions of each prefab in `prefabs_dims.json `_, which contains the center and size of the bounding box for each prefab. Objects can have different properties and states, which determine the actions you can take over them. You can find the properties for each object in `properties_data_all.json `_. Note that some of the properties do not affect yet the actions that you can take over objects. For more information over actions and objects, check out :ref:`RST_ActionsKB`. When adding new objects in a scene, via :meth:`unity_simulator.UnityCommunication.expand_scene`, you can specify the object name, in which case the simulator will pick one of the matching prefabs at random, or you can directly select the prefab. We list here the objects available in VirtualHome, along with their properties, based on `PrefabClass.json` and `prefab_dims.json`. .. include :: table_objects.rst
