Input in Unity refers to users sending signals from the outside world to your game or app using a physical device.

Unity supports input from many types of device, such as gamepads, mouse, keyboard, touchscreen, joystick, movement-sensors like accelerometers or gyroscopes, and VRVirtual Reality More info

See in Glossary controllers. Almost every project requires input of some kind, whether it is to allow users to navigate a UI, control a character in a game, or move around and interact with objects in virtual realityVirtual Reality (VR) immerses users in an artificial 3D world of realistic images and sounds, using a headset and motion tracking.

Unity has two methods of implementing Input:

• The Input System Package, which is newer, more flexible, and better supported.
• The legacy Input ManagerSettings where you can define all the different input axes, buttons and controls for your project. More info
  See in Glossary (which includes the built-in Input class).

The Input System Package

By default, the Input System Package provides input support in Unity. If needed, you can also install it through the Package Manager.

This is the recommended solution for most projects. It provides an intuitive interface in the Editor to configure input, and provides a variety of workflows to suit your project and coding style.

Get started with the Input System Package.

Legacy projects

If you are supporting a project that needs to use the older Input Manager, refer to the legacy Input Manager documentation.
