Question by FBalerio · Apr 16, 2019 at 09:50 PM · error buildcompiler error

DontDestroyOnLoad not compiling in Visual Studio

Hello, I'm a beginner making a simple project using unity 2018 with Visual Studio as an editor. I've only just set it up and I tried to call the DontDestroyOnLoad on a simple script inside the Start() function.

The call is written as follows:

public class CBattle : MonoBehaviour { // Start is called before the first frame update void Start() { DontDestroyOnLoad.(gameObject); SceneManager.sceneLoaded += OnSceneLoaded; this.gameObject.SetActive(false); } ...

Visual Studio throws a warning and doesn't allow it to compile, even though I've seen another project use this method in this way. The warning text reads: "'Object.DontDestroyOnLoad(Object)' is a method, which is not valid in the given context".

This is strange, since calling a method inside Awake, Start or Update is something I thought was normal. Additionally, other errors I'm getting include certain references not being made automatic. If I call something in the Scene Manager, I have to include it in the script's references.

Could this be related to the issue? I appreciate your help.

Your DontDestroyOnLoad.(gameObject); should be DontDestroyOnLoad(this.gameObject);

I have this method inside Awake and it works perfectly.

I know it should. Both usages of DontDestroyOnLoad(), either with (gameObject) or (this.gameObject) throw the same warning inside both Awake and Update.

Notice you incorrectly used a dot. To be used as a method, as the warning says, you need to use DontDestroyOnLoad(Object) ins$$anonymous$$d of DontDestroyOnLoad.(Object) , without the dot.

Syntax was correct.

I solved this by cutting and pasting the code line into another part, then pasting it again in the same function.

It was a Visual Studio hiccup.
