🟥 實現目標

Demo：DemoAsteroids大廳的解析

🟧 大廳思路

Awake：設置同步場景的方式登陸按鈕：同步本地昵稱、連接到服務器連接到服務器回調：關閉登陸界面，打開 創建房間 / 加入房間 / 顯示房間列表 的面板選擇界面選擇創建房間界面的Btn：打開創建房間界面創建房間界面：輸入房間名、最大人數、擁有創建房間、返回的按鈕返回按鈕：返回到功能選擇界面創建房間Btn：根據房間名、最大人數，創建服務器房間創建/加入房間回調：打開房間內面板、實例化當前所有玩家的條形信息預制體，并將（昵稱、是否準備）信息初始化到該預制體上的腳本上↓條形信息物體：上有腳本：保存了該玩家的 ID、昵稱、準備信息根據初始化的ID==本地玩家ID？不等于則不顯示該預制體的準備按鈕（即咱們不顯示別人電腦的ready，咱們只能控制咱們的ready）若等于，即代表著這個預制體是我們自己的。則顯示準備按鈕。且將準備信息等做為自定義的同步信息根據本房間內，該玩家的Number，決定這個預制體是什么顏色。（demo設定最多8人，因此這有8種對應的case）【用PUN的 Number更新回調實現】注意，這兒要用到PUN自帶的腳本：PlayerNumbering，要將其掛在場景中上有準備按鈕：每次點擊，改變自身狀態（是否關閉等）、同步自身是否準備信息若自己是主服務器，則還可根據當前玩家是否都已準備，顯示開始游戲按鈕（檢查是否都已準備，就是foreach所有玩家的準備信息，進行判斷）開始游戲按鈕：設置當前房間狀態：不可再加入、大廳列表不可見（隱身）PUN同步加載場景加入隨機房間按鈕：加入隨機房間，顯示服務器房間界面返回按鈕：退出服務器房間，返回到功能選擇界面顯示房間列表按鈕：使用加入大廳API，使PUN調用 刷新大廳列表 回調，在該回調中完成相關邏輯（該回調會傳入所有房間列表緩存）：清空、刪掉房間預制體、根據從網絡獲得的緩存列表，判斷房間是否可加入、可見性、標記性，刪除不需要的房間，將需要的房間添加到本地房間列表。更新實例化本地房間列表開始游戲按鈕狀態：只有主客戶端進行檢測判斷。（其他客戶端沒有開游戲的資格，自然不用檢測）主客戶端點擊準備時、本地玩家進入房間時、（新玩家進來了，當然關閉按鈕了）其他玩家進入房間時、（新玩家進來了，當然關閉按鈕了）其他玩家離開房間時、主客戶端切換給別人時、玩家屬性更新時、（PUN回調）房間列表更新時機：顯示房間列表信息按鈕、本地玩家退出大廳回調、本地玩家離開房間回調、其他玩家加入房間回調、其他玩家離開房間回調、

🟨 主要腳本

該場景主要由這兩個腳本實現功能

PlayerNumbering作為PUN實用腳本，掛載到場景中，配合我們寫的代碼。
