GameObject
The GameObject menu lets you create an empty GameObject. The GameObject is the base container for objects,
scripts, and other components in Unity. Like a group, it has its own transform and, so, is a logical means of organizing
similar objects or meshes. At its simplest, a GameObject contains its transforms (location and orientation) and a few
other properties. With the addition of various components, it can become almost anything you need. GameObjects
are invaluable when used as a parent group or “folder” to keep multiple scene objects organized.
You can create various objects, such as lights, particle systems, GUI 2D objects, and Unity primitive objects from
scratch with Components or find them ready-made in the Create Other submenu. Unlike many modeling programs,
you cannot change the number of segments in Unity’s primitive objects.
