uloop replay-input

Replay recorded keyboard and mouse input during PlayMode. Loads a JSON recording and injects input frame-by-frame via Input System with zero CLI overhead. Supports looping and progress monitoring.

Create recording JSON files in the Unity Editor from Window > Unity CLI Loop > Recordings with Start Recording and Stop Recording. There is no CLI command for recording input.

Usage

# Start replay (auto-detect latest recording)
uloop replay-input --action Start

# Start replay with specific file
uloop replay-input --action Start --input-path scripts/my-play.json

# Start replay with looping
uloop replay-input --action Start --loop

# Check replay progress
uloop replay-input --action Status

# Stop replay
uloop replay-input --action Stop

Parameters

Parameter Type Default Description
--action enum Start Start - begin replaying, Stop - stop mid-way, Status - check progress
--input-path string auto Path to the recording JSON. When empty, auto-detects the latest recording in .uloop/outputs/InputRecordings/
--no-show-overlay flag - Hide replay progress overlay
--loop flag - Loop continuously

Deterministic Replay

Replay injects the exact same input frame-by-frame, but the game must also be deterministic to produce identical results. If replay output must be compared across runs, read [references/deterministic-replay.md](references/deterministic-replay.md) before interpreting failures.

Prerequisites

  • Unity must be in PlayMode
  • Input System package (com.unity.inputsystem) must be installed; this tool only works with the New Input System.

Output

Returns JSON with:

  • Success: Whether the operation succeeded
  • Message: Status message
  • Action: Echoes which action was executed (Start, Stop, or Status)
  • InputPath: Path to recording file (nullable string; populated on Start only)
  • CurrentFrame: Current replay frame index (nullable int)
  • TotalFrames: Total frames in the recording (nullable int)
  • Progress: Replay progress (nullable float in 0.0 – 1.0)
  • IsReplaying: Whether replay is currently active (nullable bool)
