Unity/Csharp/シングルトン

MonoBehaviourを使ったシングルトン

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SampleManager : MonoBehaviour {
	private static SampleManager mInstance;
	public int x = 1;
	private SampleManager () {
	}
	public static SampleManager Instance {
		get {
			if (mInstance == null) {
				GameObject go = new GameObject("SampleManager");
				mInstance = go.AddComponent<SampleManager>();
			}
			return mInstance;
		}
	}
	void Start () {
	}
	void Update () {
	}
}

使用方法

SampleManager manager = SampleManager.Instance;
Debug.Log("x=" + manager.x);
