Unity --- game design pattern (3) of the singleton

See the overview Reference Reference blog

Use singleton pattern is very extensive, I believe we learn design patterns before, he had come into contact with the singleton pattern.

1, singleton

Singleton in C #

public class Test
{
    private static Test _instance;
    public static Test Instance
    {
        get
        {
            if (_instance == null)
                _instance = new Test();
            return _instance;
        }
    }
}

In singleton Unity

public class Test : MonoBehaviour
{
    public static Test Instance;

    private void Awake()
    {
        Instance = this;
    }
}
