DC音樂機器人製作

因為最近dc很多音樂機器人都壞掉
一氣之下就直接~~透過chatGPT~~寫一個出來了

前言

其實真的沒啥技術含量，因為代碼真的都是叫GPT幫我搓出來的
但還是想說丟上來好了，畢竟在自己本地架機器人就不用看其他人的臉色了 (X 基本上會從頭開始講如何建立，但有些我沒碰到的功能就不會特別介紹
~~因為我自己也不懂~~
想抄代碼的可以直接跳到那邊就好了
但還是放一下跟GPT溝通的流程之類的 ~~水一下內容~~

建立DC機器人

首先先到 Discord Developer Portal 建立一個機器人出來
登入後左上角New Application點下去，再取個名子，專屬你ㄉ機器人就誕生了

New Application

剛進去就可以先看到設定的介面，這邊基本上就是可以設定機器人的名稱、頭貼、還有點進機器人會看到的描述
然後DESCRIPTION的部分會在關於我的部分顯示

取得token
#

接著到旁邊選單選擇Bot
在這邊可以額外設定機器人的橫幅(BANNER)
而我們這邊主要要取得機器人的TOKEN
點下去Reset Token確認後取得全新的token先自己記起來

切記不要外洩因為有token就能夠執行你的機器人了

Reset Token

接著滑到下面Privileged Gateway Intents的部分，接著把三個選項都打勾
這邊主要是要讓機器人能夠接收指令與用戶互動

邀進伺服器
#

進入OAuth2的部分，滑到最下面的OAuth2 URL Generator
主要勾選bot就好
而下面的BOT PERMISSIONS則是勾選Administrator
直接拿所有權限就不用再慢慢設定了

bot

Administrator

再來往下看就可以在 GENERATED URL 看到你機器人的邀請連接了

基本上機器人的部分就到這邊了再來就是要寫code的部分了

代碼

安裝所需的庫
#

打開你的cmd 一起快樂安裝

pip install discord.py youtube_dl
pip install yt-dlp

ffmpeg安裝
#

前往 BtbN FFmpeg Releases下載 ffmpeg-master-latest-win64-gpl.zip
解壓縮後丟到一個不太會動到的地方
接著打開環境變數，win11打開環境變數的方法如下
設定系統系統資訊進階系統設定再來就能看到環境變數了
接著選擇Path然後編輯，新增你剛剛解壓縮下來的檔案中bin資料夾的位置 (C:\ffmpeg\bin) 這樣就順利安裝完成了，可以檢查看看有沒有順利安裝，沒有的話就重開機看看

ffmpeg -version

bot.py
#

主要可以分兩種撥放方式
1.線上串流(較不穩定)
2.下載到本機(很穩定)

線上串流
#

先講第一種線上串流的部分
穩定性的部分就真的很爛大概每首歌都撥不完大概撥個一兩分鐘左右而已

反正就又卡又容易斷掉不如乖乖下載下來

下載到本地
#

因為是現在還有在用ㄉ，所以加了一些功能
基本上就自己看一下code就能知道具體功能了這邊就不多講了然後下載到本地的話也不是全部下載，我是設定成一次本地只會有一首歌而已，然後撥下一首的時候就把前面的刪掉，所以不用怕自己電腦被灌爆 >.0

運行方法
#

其實就只要運行py檔案就好了
看你是要在cmd中執行還是直接在編譯器(我是用vs)跑都可以

python bot.py

與chatGPT交流

夢ㄉ開始

不知道為甚麼chatGPT一開始都是用java寫的，可能因為其實普遍都是用java寫吧，但我看不懂java所以都叫他寫python(
其實好像也沒有甚麼特別要講的，基本上就都是想要什麼功能就講甚麼
我覺得比較好玩的大概有nowplay功能而已就是跟他說—–o—-來表達進度條

大概就這樣，有甚麼問題不要DM我，去問chatGPT這都他寫的(X
