How to make antispam function discord.py? - variables

Question

I need antispam function on my discord server. Please help me. I tried this:
import datetime
import time
time_window_milliseconds = 5000
max_msg_per_window = 5
author_msg_times = {}
#client.event
async def on_ready():
print('logged in as {0.user}'.format(client))
await client.change_presence(activity=discord.Activity(type=discord.ActivityType.playing,name="stack overflow"))
#client.event
async def on_message(message):
global author_msg_counts
ctx = await client.get_context(message)
author_id = ctx.author.id
# Get current epoch time in milliseconds
curr_time = datetime.datetime.now().timestamp() * 1000
# Make empty list for author id, if it does not exist
if not author_msg_times.get(author_id, False):
author_msg_times[author_id] = []
# Append the time of this message to the users list of message times
author_msg_times[author_id].append(curr_time)
# Find the beginning of our time window.
expr_time = curr_time - time_window_milliseconds
# Find message times which occurred before the start of our window
expired_msgs = [
msg_time for msg_time in author_msg_times[author_id]
if msg_time < expr_time
]
# Remove all the expired messages times from our list
for msg_time in expired_msgs:
author_msg_times[author_id].remove(msg_time)
# ^ note: we probably need to use a mutex here. Multiple threads
# might be trying to update this at the same time. Not sure though.
if len(author_msg_times[author_id]) > max_msg_per_window:
await ctx.send("Stop Spamming")
ping()
client.run(os.getenv('token'))
And it doesn't seem to work when I type the same message over and over again. Can you guys please help me? I need the good antispam function which will work inside on_message

I think the best thing you can do is to make an event on_member_join, which will be called every time user joins. Then in this event, you can make a list instead of variables that will save user id, and their current currency.
users_currency = ["user's id", "5$", "another user's id", "7$"] and so on. Next, I would recommend saving it to a text file.
Example code
global users_currency
users_currrency = []
#client.event
global users_currency
async def on_member_join(member): #on_member_join event
user = str(member.id) #gets user's id and changes it to string
users_currency.append(user) #adds user's id to your list
users_currency.append("0") #sets the currency to 0
Now if someone will join their id will appear in list and change their currency to 0.
How can you use assigned values in list
If you keep the code close to example higher then on users_currrency[0], users_currrency[2], [...]. You will get users' ids and on users_currrency[1], users_currrency[3], etc. You will get their currency. Then you can use on_message event or #client.command to make command that will look for user's id in list and change next value - their currency.
Saving it to a text file
You have to save it in a text file (Writing a list to a file with Python) and then make a function that will run at the start of the bot and read everything from the file and assign it inside your list.
Example code:
with open("users_currency.txt") as f:
rd=f.read()
changed_to_a_list=rd.split()
users_currency = changed_to_a_list
