Start方法结束并按下按钮后，带有“ new”关键字的实例化类为null。 Unity3d

Question

I have a SaveController, it looks like this:

In the Start method of a MainMenuLogic class, I instantiate an instance of SaveController:

When the game starts, MusicOn method has been called before the Start method is called so the soundController is null...

public void MusicOn(bool on)
{
    saveController.MusicOn(on);
}

I've obviously not understood the application flow, so wondered if anyone has an idea on what might be going wrong. Which method should i instantiate the SaveController?

PS I know, GameObject.Find, bleurgh... i'm refactoring, no wuckers.

Answer 1

Looks like Awake was the method i was looking for.

Awake is called before Start , so doing the saveController instantiation in Awake allows for the instantiation to happen before MusicOn is called.

void Awake() 
{
    saveController = new SaveController();
}
