The program I made to make Voiceroid read Discord messages using Python 3.6 was not usable after Python 3.7. (From a year ago) Also, the version of Discord.py was so old that I wanted to update it. (It was discovered that it did not work after updating)
I wanted to use Python for the first time in a long time, so let's fix it!
The environment assumed this time is as follows. -Python 3.7.4 ・ Discord.py 1.2.4 ・ Windows 10
Please refer to other pages for Python environment settings. Please use your favorite editor etc.
I would like to make a simple echo bot. I made it the last time Discord.py 0.x, so I couldn't use it now.
EchoBot.py
# Discord.py 0.x
import discord
client = discord.Client()
@client.event
async def on_ready():
print("-"*35)
print("user name：", client.user.name)
print("user id：", client.user.id)
print("-"*35)
@client.event
async def on_message(message):
#Don't react to your own message
if client.user != message.author:
#Write a message
m= message.author.name +"The message sent by"+message.content+"is"
#Send a message to the channel to which the message was sent
await client.send_message(message.channel, m)
client.run("BOT token")
It's as simple as sending back a message from someone other than a bot. We will modify this to match 1.X. This time, it is in ʻon_message` that needs to be modified.
EchoBot_after.py
@client.event
async def on_message(message):
if message.author.bot: #Ignore if the message sender is a bot
return
#Send to the posted channel
await message.channel.send(f"{message.author.name}Message from{message.content}is")
Since it is an echo bot, this kind of modification is enough, but it seems to be difficult for a multifunctional application.
Here is a lot of rewrites
EchoBot.py
import discord
import re
client = discord.Client()
CHANNEL_ID = "ID of the main channel"
@client.event
async def on_ready(): #Show ID and name on console at startup
print("-"*50)
print(client.user.name) # User Name
print(str(client.user.id)) # User ID
print(""*50)
print("Bot invitation URL")
strURL = "https://discordapp.com/oauth2/authorize?&client_id="
strURL += str(client.user.id) + "&scope=bot&permissions=0"
print(strURL)
print("-"*50)
print(f"client : {client}")
print(f"client.user : {client.user}")
print("-"*50)
channel = client.get_channel(CHANNEL_ID)
await channel.send("It has started.") #Notify when started
@client.event
async def on_message(message): #Processing that operates when receiving a message
if message.author.bot: #Ignore if the message sender is a bot
return
if client.user in message.mentions: #I will reply when a reply comes
await message.channel.send( f"{message.author.mention}called?") #Send a reply message
return
Msg = message.content
if re.search(r"http(.*)", Msg):
Msg = re.sub(r"http(.*)", ", URL below", Msg) #URL omitted
await message.channel.send(f"{message.author.name}Message from{Msg}is")
client.run("BOT token")
This completes the echo bot.
You can get the person's guild nickname by replacing the message.author.name part with message.author.nick.
This is an assortment of client functions (functions that I think I will use personally) that I made to check various things while updating.

There was a function to change its own status, change the name and rules of the guild, and react in various ways, but I collected the parts that I could use.
