• Test Input: Monitor live device activity, action phases, and processed values.
• Unassigned Controls: Detect working controls that are not connected to an action.
• Rebind Safety: Evaluate proposed controls on a temporary asset copy.
• Change Safety: Identify changes that could invalidate saved player rebinds.
• Shared-Control Analysis: Find overlapping controls and mark intentional overlaps.

Find input problems before they reach your players.

Input Map Doctor is an Editor-only diagnostic and testing toolkit for Unity’s Input System.

It gives you one clear place to inspect, validate, and test your project’s complete input setup.

Understand your device coverage

• See which actions work with each control scheme.
• Define devices as Required, Optional, or Not used.
• Find missing bindings and incomplete device support.
• Detect invalid controls, composites, processors, and interactions.

Check your project integration

• Inspect scenes and prefabs for PlayerInput components.
• Validate InputSystemUIInputModule configuration.
• Find missing actions, incorrect references, and incomplete UI input setup.
• Open affected Input Actions assets directly from reported findings.

Test real input

The built-in Test Input workspace displays live activity from keyboards, mice, gamepads, touchscreens, and other Input System devices.

Review:

• Started, Performed, and Canceled action phases.
• Raw and processed values.
• Active devices and controls.
• Shared controls that trigger multiple actions.
• Working controls that are not assigned to any action.

Protect saved player rebinds

Create a binding snapshot before release and compare it with future revisions.

Input Map Doctor identifies binding changes that could invalidate saved player rebinds.

The Rebind Safety Simulator tests a proposed control on a temporary copy and reports conflicts, compatibility changes, and affected actions without modifying your source asset.

Safe by design

• Editor-only code with no runtime components.
• Read-only analysis by default.
• No project data is sent to external services.
• Explicit controls for every operation that saves or applies a change.
• Uses supported public Unity APIs.

Requirements

• Unity 2022.3.0f1 or newer.
• Unity Input System 1.14.0 (com.unity.inputsystem).
• Unity UI 1.0.0 (com.unity.ugui).

Both dependencies are official Unity Registry packages and are declared in the uploaded package manifest.
