Use gameobject from other scene

Excuse me, I want ask about this for example :
I have 2 scene, scene start and scene main.
at scene start I have button, if I press it I want to change the object at scene main. How I can use that object properties at scene main for button at scene start. Thanks

 

There's two ways that you could this :
1. Use PlayerPrefs to save & load the changes.
2. Use DontDestroyOnLoad on the object at scene main.

 

which better, I mean for fast load. 1 and 2 have different and some + can u explain to me ??

 

DontDestroyOnLoad would be the easier method.

In a script in your scene main, add this piece of code to any of your scripts :

Code (CSharp):

1. public GameObject myObject; //Assign the object here
2.  
3. void Awake(){
4. DontDestroyOnLoad(myObject);
5. }

The object wont get destroyed when loading different scenes which means you can change it's properties at scene start and retain them when loading back to scene main.
