File contents

uloop record-input

Record keyboard and mouse input during PlayMode frame-by-frame into a JSON file. Captures key presses, mouse movement, clicks, and scroll events via Input System device state diffing.

Usage

# Start recording
uloop record-input --action Start

# Start recording with key filter
uloop record-input --action Start --keys "W,A,S,D,Space"

# Stop recording and save
uloop record-input --action Stop

# Stop and save to specific path
uloop record-input --action Stop --output-path scripts/my-play.json

Parameters

Parameter	Type	Default	Description
`--action`	enum	`Start`	`Start` - begin recording, `Stop` - stop and save
`--output-path`	string	auto	Save path. Auto-generates under `.uloop/outputs/InputRecordings/`
`--keys`	string	`""`	Comma-separated key filter. Empty = all common game keys

Deterministic Replay

Replay injects input frame-by-frame, so the game must also be deterministic to produce identical results. If the recording will be used for E2E tests, bug reproduction, or replay verification, read references/deterministic-replay.md before designing assertions or game logic.

Prerequisites

Unity must be in PlayMode
Input System package must be installed (com.unity.inputsystem)
Use this only when the project already uses the New Input System.

Output

The CLI prints JSON with:

Success: Whether the operation succeeded
Message: Status message
Action: Echoes which action was executed (Start or Stop)
OutputPath: Path to saved recording (nullable; populated on Stop only)
TotalFrames: Number of frames recorded (nullable int; populated on Stop only)
DurationSeconds: Recording duration in seconds (nullable float; populated on Stop only)

The CLI output contains only these six payload fields. Internal metadata such as Ver is removed before printing. There is no RecordingId, StartTimestamp, KeysCaptured, or per-frame data in the response — frame data lives only in the JSON file at OutputPath.
