Output

Returns JSON with the current play mode state:

  • IsPlaying: Whether Unity is currently in play mode
  • IsPaused: Whether play mode is paused
  • Message: Description of the action performed

Notes

  • Play action starts the game in the Unity Editor (also resumes from pause)

  • Stop action exits play mode and returns to edit mode

  • Pause action pauses the game while remaining in play mode

  • Useful for automated testing workflows

  • PlayMode entry may complete on the next editor frame. If a PlayMode-dependent command reports "PlayMode is not active" immediately after --action Play, wait briefly and retry.
