一、实现目标

Demo：DemoAsteroids大厅的解析

二、大厅思路

 Awake：设置同步场景的方式  登陆按钮：同步本地昵称、连接到服务器  连接到服务器回调：关闭登陆界面，打开 创建房间 / 加入房间 / 显示房间列表 的面板选择界面  选择创建房间界面的Btn：打开创建房间界面      创建房间界面：输入房间名、最大人数、拥有创建房间、返回的按钮         返回按钮：返回到功能选择界面      创建房间Btn：根据房间名、最大人数，创建服务器房间          创建/加入房间回调：打开房间内面板、实例化当前所有玩家的条形信息预制体，并将（昵称、是否准备）信息初始化到该预制体上的脚本上↓             条形信息物体：上有脚本：保存了该玩家的 ID、昵称、准备信息                            根据初始化的ID==本地玩家ID？不等于则不显示该预制体的准备按钮（即咱们不显示别人电脑的ready，咱们只能控制咱们的ready）                             若等于，即代表着这个预制体是我们自己的。则显示准备按钮。且将准备信息等做为自定义的同步信息                             根据本房间内，该玩家的Number，决定这个预制体是什么颜色。（demo设定最多8人，因此这有8种对应的case）【用PUN的 Number更新回调实现】                             注意，这儿要用到PUN自带的脚本：PlayerNumbering，要将其挂在场景中                          上有准备按钮：                             每次点击，改变自身状态（是否关闭等）、同步自身是否准备信息                             若自己是主服务器，则还可根据当前玩家是否都已准备，显示开始游戏按钮（检查是否都已准备，就是foreach所有玩家的准备信息，进行判断）                          开始游戏按钮：                             设置当前房间状态：不可再加入、大厅列表不可见（隐身）                             PUN同步加载场景                   加入随机房间按钮：加入随机房间，显示服务器房间界面         返回按钮：退出服务器房间，返回到功能选择界面      显示房间列表按钮：使用加入大厅API，使PUN调用 刷新大厅列表 回调，在该回调中完成相关逻辑（该回调会传入所有房间列表缓存）：         清空、删掉房间预制体、         根据从网络获得的缓存列表，判断房间是否可加入、可见性、标记性，删除不需要的房间，将需要的房间添加到本地房间列表。         更新实例化本地房间列表          开始游戏按钮状态：只有主客户端进行检测判断。（其他客户端没有开游戏的资格，自然不用检测）     主客户端点击准备时、     本地玩家进入房间时、（新玩家进来了，当然关闭按钮了）     其他玩家进入房间时、（新玩家进来了，当然关闭按钮了）     其他玩家离开房间时、     主客户端切换给别人时、     玩家属性更新时、（PUN回调）   房间列表更新时机：     显示房间列表信息按钮、     本地玩家退出大厅回调、     本地玩家离开房间回调、     其他玩家加入房间回调、     其他玩家离开房间回调、 

三、主要脚本

该场景主要由这两个脚本实现功能

PlayerNumbering作为PUN实用脚本，挂载到场景中，配合我们写的代码。
