Unity currently supports three UI systems. See 2D Physics.Ĭomponents are UI (User Interface) Allows a user to interact with your application. This is mostly useful for making isometric or 2D games.Ĭollider 2D: this component defines the shape of a 2D GameObject for the purposes of physical collisions A collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. Marking a Camera as Orthographic removes all perspective from the Camera’s view.
More info See in Glossary: devices that capture and display the world to the player. The output is either drawn to the screen or captured as a texture. More info See in Glossary: the Sprite Renderer component renders the Sprite and controls how it looks in a scene.Ĭameras A component which creates an image of a particular viewpoint in your scene. Sprite Renderer A component that lets you display images as Sprites for use in both 2D and 3D scenes. Every GameObject has a Transform component. More info See in Glossary determines the Position, Rotation, and Scale of each GameObject in the scene. Transform: the Transform component A Transform component determines the Position, Rotation, and Scale of each object in the scene. The following components are fundamental for 2D games: The behavior of GameObjects is defined by blocks of functionality called components. Scenes in Unity are always 3D when you make a 2D game in Unity, you typically choose to ignore the third dimension (the z-axis) but you can also use it in special cases, for example when making 2.5D games. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. GameObjects represent the items in your game the space in which you place them to build your level is called a scene A Scene contains the environments and menus of your game. Every object in your game is a GameObject. More info See in Glossary are fundamental objects in Unity that represent characters, props, scenery, and more.
A GameObject’s functionality is defined by the Components attached to it.
GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. To create a 2D game, set up your Unity project and then familiarize yourself with the relevant concepts in the following order: Before you create a 2D game, you need to decide on a game perspective and an art style.
