So I'm making a swear filter using an Array and I'm having trouble with the chat event being called.
Here's the code in my main that registers the chatlistenr

public static LearningSpigot plugin;
public void onEnable() {
....
 pm.registerEvents(new ChatListener(this), this);

📎 ChatListener.java

type hell in chat

#

and see what it does

restive geode Dec 22, 2022, 3:04 AM

#

I did I type different swears and it sends the message as normal

#

Let me try putting message.contains instead of equals ignore case

wanton elk Dec 22, 2022, 3:09 AM

#

To lower case the message before contains chekc

restive geode Dec 22, 2022, 3:11 AM

#

That did not work

#

oh wait

#

I just checked console

restive geode I did I type different swears and it sends the message as normal

you havent registered the actual listener

clear dew Dec 22, 2022, 3:15 AM

#

yes they did, or it would not be trying to pass the event.

#

the issue appears to be that you are indexing your array from 1

#

its trying to get array pos 0

#

that is null

#

cannot compare null

restive geode Dec 22, 2022, 3:16 AM

#

aahh I always forget about arrays starting at 0

clear dew Dec 22, 2022, 3:16 AM

#

you indexed your array from 1 but looped from 0

#

so, yeah

#

also this appears to only filter chat if their message is only exactly one of the swear words?

restive geode Dec 22, 2022, 3:18 AM

#

no it works if the message contains other strings + swears

#

Also it works now

#

thanks for your help

clear dew Dec 22, 2022, 3:18 AM

#

oh, the contains

#

however, this filter is susceptible to the clbuttic mistake

#

type the word classic, which is a valid non-swear word but it contains the substring ass

#

your filter will say "bad word"

restive geode Dec 22, 2022, 3:19 AM

#

yeah It's very arachic. I don't even have it setup so that ops can add filters without re-compiling

#

I just wanted to get it setup first

clear dew Dec 22, 2022, 3:19 AM

#

alrighty

#

filters are not easy to make, which you'll probably soon come to realize. but good luck!

#

Thanks for your help, I'm actually a freshman in college right now so I'm making this to learn Java

wanton elk Dec 22, 2022, 3:20 AM

#

Adding config variables isnt hard

clear dew Dec 22, 2022, 3:22 AM

#

yep it is good practice. but the problem itself is difficult, specially in figuring out how to fix the clbuttic mistake. it's actually a notorious problem in computer science

#

but, have fun

if interested. will take my leave now

Scunthorpe problem

The Scunthorpe problem is the unintentional blocking of websites, e-mails, forum posts or search results by a spam filter or search engine because their text contains a string (or substring) of letters that appear to have an obscene or otherwise unacceptable meaning. Names, abbreviations, and technical terms are most often cited as being affecte...

restive geode So I'm making a swear filter using an Array and I'm having trouble with the chat...

this is more of a LearningJava instead of LearningSpigot type of case 💀

#

or actually, learning basic logic

#

first things first you would want to retrieve an actual list of swear words, so I would recommend https://github.com/coffee-and-fun/google-profanity-words/blob/main/data/list.txt

#

then, you would get the message to lowercase

#

split the message into words

#

check if array of bad words contains any word from the message

#

if it does, do what you want it to do
