how to pass bool value form previous scene to new scene , note { previous scene get destroyed before loading new scene } describe my situation :-
i am hitting a trigger call "END trigger" and trying to pass a bool value true for new scene
(accessing another script , "reward panel testing " script to activate reward panel game object..

for activation bool A is responsible ... please help

 

The absolute most simple way is to make public static bool that both scripts look at.

Code (csharp):

1. public Scene1Script : Mono
2. {
3.     public static bool boolForScene2 = false; // Static variables belong to a type, NOT instances of that type. All instances share it; if any change it, it will change for all of them.
4.  
5.     private void CallMeBeforeSwitchingScenes()
6.     {
7.           boolForScene2 = true;
8.     }
9. }
10.  
11. public Scene2Script : Mono
12. {
13.     private void Awake()
14.     {
15.         if(Scene1Script.boolForScene2 == true) // Note that this refers to the type, NOT an instance of the type
16.             Debug.Log('Yay!);
17.    }
18. }

 

You can pass a GameObject between scenes with whatever data you want in attached MonoBehaviour scripts. You do this by setting DontDestroyOnLoad. Google it for example.

Static variables as above are also good.

 

thanks for the valuable time you gave its working !
