使用篇八，对象池

在开头

相信看到对象池，大家是很熟悉了
就算你不熟悉，如果你在优快云 搜索的话，我相信可以搜索到 一堆开手枪的 unity版本对象池
那么IF的有什么区别？IF主要提供了三种对象池
1、自动实例化的对象池
2、自己个性化管理生命周期的对象池
3、基类对象池，这是啥？简单讲解：声明一个动物的对象池，你可以取出猫，同时也可以取出狗

上马，上马

        protected override void Stop()
        {
        }

        protected override void Update()
        {
        }
    }

让我们来看看结果，用起来很简单吧
