[C# Tutorial] a deeper look into singletons in unity3d

In this tutorial I make a more detailed discussion about the nuances of singleton usage in unity 3d and of the tradeoffs involved.
Also, I explain how to obtain the equivalent of a static class with an inspector.

Thanks !

I usually do that:

Code (CSharp):

1. public class LazySingleton : Monobehaviour {
2. private static LazySingleton instance;
3.     public static LazySingleton Instance
4.     {
5.        get
6.        {
7.           if (instance  == null)
8.           {
9.               instance = GameObject.FindObjectOfType<LazySingleton>();
10.           }
11.           return instance;
12.        }
13.     }
14. }

Since I know that my class is already in the scene.
But many of my projects are small, I see it can be a problem on a long & large dev.
I will think about your Option B: Handcrafting next time !

 

Hi thanks for the reply, even if you don't use option B I'd suggest to move the FindObject there:
https://docs.unity3d.com/ScriptReference/RuntimeInitializeOnLoadMethodAttribute-ctor.html

Code (CSharp):

1. [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
2. static void OnBeforeSceneLoadRuntimeMethod ()
3. {
4.           if (instance  == null)
5.           {
6.               instance = GameObject.FindObjectOfType<LazySingleton>();
7.          }
8.          return instance;
9. }

So that the search is not done during the game
