Objects are all elements of our game. Cameras, lights, 3D models, sprites, particle effects, user interface elements. A project can be composed of one or more scenes. The House is the subjective view of the video game. In game mode, the action is taken from exactly where the camera is located. In Unity you can create simple objects, but to develop complex objects you should operate with modeling software (such as SketchUp) and then import the 3D models and textures, which will appear among the assets of the scene, where you can move, scale and rotate them. The objects in the Scene View are all considered "game objects".

Game objects can be equipped with interactive features through a simplified programming language that allows basic interactions to be made. Each Game Object has a name and some basic properties, and can be placed in the 3D space and provided with a script. Game Objects can be very different: they can be visible or invisible, emit sounds or be interactive. While the Scene View provides an operational view of the 3D scene in which the game takes place, the Game View is available to show what players will see during the action, showing the viewpoint of the game camera.

When Play is pressed on the Game panel, Unity starts running the game, which can finally be exported via the build function, to a large number of platforms and devices, including PCs, smartphones, tablets and augmented reality and virtual viewers.
