About the Player Input component

Above, the Player Input component displayed in the inspector.

Connecting actions to methods or callbacks

The Player Input component represents a single player, and the connection between that player's associated device, Actions, and methods or callbacks.

You can use a single instance of a Player Input component in a single-player game to set up a mapping between your Input Actions and methods or callbacks in the script that controls your player.

For example, by using the Player Input component, you can set up a mapping between actions such as "Jump" to C# methods in your script such as public void OnJump().

There are a few options for doing exactly how the Player Input component does this, such as using SendMessage, or Unity Events, which is described in more detail below.
