Unity 单例类模板+对象池的简单使用（记录方便拷贝使用）

一.单例类模板

using UnityEngine;
/// 
/// 通用Mono单例模板
/// 
/// 
public abstract class MonoSingleton : MonoBehaviour where T : MonoSingleton
{
    private static T ms_instance;

    public static T Instance
    {
        get
        {
            if (ms_instance == null)
            {
                ms_instance = Instantiate();
            }

            return ms_instance;
        }
    }

    protected static T Instantiate()
    {
        if (ms_instance != null) return ms_instance;

        // 在场景中查找T类型的Mono类
        ms_instance = (T)FindObjectOfType(typeof(T));
        if (FindObjectsOfType(typeof(T)).Length > 1)
        {
            return ms_instance;
        }

        if (ms_instance != null) return ms_instance;

        // 创建GameObject实例
        var singleton = new GameObject("[Singleton]" + typeof(T).Name);
