Keeping character's data through levels

Questions & Answers

Hello, I’m a begginer in Unity and I’d like to learn how to change a scene and how to keep my character’s data in all scenes(like life remaining, etc.). I also would like to do a menu in the same way. I think it is a matter of design, and I would like to learn how to design it. Thank you and sorry about my english

You’d just pop a DontDestroyOnLoad onto whatever you’d like to maintain.

The easiest way is probably to use DontDestroyOnLoad(). I would create a scene manager that is responsible for loading levels and managing player health and inventory and other similar things. Then tell Unity not to destroy it when the level changes.

 //SomeOtherScript.js
 static var gameManager : YourPlayerManager;

 function Start () {
      gameManager = FindObjectOfType(YourPlayerManager) as YourPlayerManager;
      DontDestroyOnLoad(gameManager.gameObject);
 }
 //Now that object will not be destroyed when you load a new level and you can 
 //access it using SomeOtherScript.gameManager.
