The input debugger window

When something isn't working as expected, the quickest way to troubleshoot what's wrong is the Input Debugger in the Unity Editor. The Input Debugger provides access to the activity of the Input System in both the Editor and the connected Players.

To open the Input Debugger, go to Window > Analysis > Input Debugger from Unity's main menu.

Input Debugger

The Input Debugger displays a tree breakdown of the state of the Input System.

Item	Description

A list of all currently active users, along with their active Control Schemes and Devices, all their associated Actions, and the Controls these Actions are bound to. Note that PlayerInput uses InputUser to run. When using PlayerInput components, each player has an entry in this list. Refer to Debugging users and PlayerInput.
