Unity（二十） 关于SteamVR里Action的使用

SteamVR封装好了一个事件工具类

public static class SteamVR_Utils
{
	public class Event
	{
		public delegate void Handler(params object[] args);

		public static void Listen(string message, Handler action)
		{
			var actions = listeners[message] as Handler;
			if (actions != null)
			{
				listeners[message] = actions + action;
			}
			else
			{
				listeners[message] = action;
			}
		}

		public static void Remove(string message, Handler action)
		{
			var actions = listeners[message] as Handler;
			if (actions != null)
			{
				listeners[message] = actions - action;
			}
		}

		public static void Send(string message, params object[] args)
		{
			var actions = listeners[message] as Handler;
			if (actions != null)
			{
				actions(args);
			}
		}

		private static Hashtable listeners = new Hashtable();
	}
}

很方便开发者添加事件来驱动

测试如下：

public class MyAction
