How to Manage and Save Game States to Trigger Events and Enable Script Communication in Unity?

Body:
Hello,
I’m developing a 2D Unity game and need advice on managing and saving the player’s current state to trigger various events and communicate between scripts. Specifically, I want to:

  1. Track the player’s state: For example, detect whether the player is in the game, at a specific location, or performing a particular action.
  2. Trigger events based on state: For instance, start a “dream sequence” when the player enters the game.
  3. Control other scripts: From a central script, toggle booleans in other scripts, like enabling or disabling camera follow behavior.

For context:

  • At the start of the game, the camera should be fixed.
  • After the dream sequence, the camera should transition to follow the player again.

What is the best approach to achieve this? Should I use a Game Manager or State Manager to handle the game’s progress and centralize control over other scripts? Also, how can I save and load the player’s state to enable flexibility in event handling?

I’d appreciate any code examples or best practices for implementing this kind of system. Thank you!
