# Replit
https://replit.com/
註冊帳號
### Ceate Repl
### Add Secret

>按add secret
>
>加這幾行導入secret內容
### 最後應該長這樣
### 按Run執行，bot上線

# 線上託管

## keep alive
下載相關檔案 :

### 把keep_alive.py上傳到repl裡

### 加入下面的程式碼

import keep_alive

keep_alive.keep_alive()


## UptimeRobot
>bot監視器

註冊帳號

### add new monitor

### url取得


### 然後記得回去按Run

# Cogs
> 把你的功能模組化

### 類別(class)
>物件導向(OOP)

其實就是分門別類
以"學校"為例
其實我們創建的是名稱是"學校"的物件(定義何為"學校")

用法:

class school:
    
    #constructor
    def __init__(self, student):
        #attribute
        self.table=10
        self.chair=5
        self.student=student
       
    #method
    def good_morning(self):
        print("Hello!!!")
        
    #method      
    def student_num(self):
        print(self.student)

TCFSH = school(1000)
TCGS = school(2000)

print(TCFSH.table) #10
print(TCGS.table)  #10
print(TCFSH.student) #1000
print(TCGS.student)  #2000

TCFSH.student_num()  #1000
TCFSH.good_morning() #"Hello!!!"

### 寫法
main.py :

for fn in os.listdir("cogs"):
    if fn.endswith(".py"):
        bot.load_extension(f"cogs.{fn[:-3]}")
  
@bot.event
async def on_ready():
    print(f"目前登入身份 --> {bot.user}")
    channel=bot.get_channel(int(os.environ['contest_channel']))
    await bot.change_presence(status=nextcord.Status.online, activity=ectivity)

@bot.command()
async def load(ctx,extension):
    bot.load_extension(f"cogs.{extension}")
    await ctx.send("loaded cog!")

@bot.command()
async def unload(ctx,extension):
    bot.unload_extension(f"cogs.{extension}")
    await ctx.send("unloaded cog!")

@bot.command()
async def reload(ctx,extension):
    bot.reload_extension(f"cogs.{extension}")
    await ctx.send("reloaded cog!")

func.py :

import nextcord
from nextcord.ext import commands

class func(commands.Cog):

  def __init__(self,bot):
      self.bot = bot
      self.number = 10
    
  @commands.command()
  async def my_func(self, ctx):
      await ctx.send("嗨嗨")

def setup(bot):
    bot.add_cog(roles(bot))

### cogs資料夾
記得新增一個cogs資料夾
把所有cog檔案都放進去(main.py和keep_alive.py不用放)

## 沒了
