Many game objects have slots for associating assets with the game object. You associate an asset with a game object by dragging the asset to the appropriate slot for the game object in the Project Lister.
The types of assets that a slot can accommodate depend on how the slot was set up; you can associate only assets of a type that the slot can accept. For example, the geometry slot for the Orc example can accept only geometry assets. If you drag a behavior or texture asset to the geometry slot, the LevelEditor does not accept the asset.
To associate an asset with a slot, drag the asset to the game object’s slot in the Project Lister. You can overwrite an existing asset by dragging a new asset to the slot.
To remove an asset from a slot, select the asset in its assigned slot and select the Edit > Delete menu item.
