bad words block help

I have a login system to register the user in mysql, is it possible to block bad name and words to register?

 

It's easy to block the words. The simple way would be to just made a list of strings and check through them:

Code (CSharp):

1.     public class CheckWords : MonoBehaviour
2.     {
3.         [SerializeField] private string[] naughtyWords;
4.  
5.         public bool VerifyCleanWord(string word)
6.         {
7.             for (int i = 0; i < naughtyWords.Length; i++)
8.             {
9.                 if (word.Contains(naughtyWords[i]))
10.                 {
11.                     return false;
12.                 }
13.             }
14.             return true;
15.         }
16.     }

To really protect it in detail you'd probably need to use Regular Expressions. It might be overkill, but if you reach a state where you need more detail on the words, use Regex. Eg:

Code (CSharp):

1. using System.IO;
2. using System.Text.RegularExpressions;
3.  
4.     public class CheckWords : MonoBehaviour
5.     {
6.         [SerializeField] string[] words;
7.         private string wordChecker = String.Empty;
8.  
9.         private void Awake()
10.         {
11.             for(int i=0; i < words.Length; i++)
12.             {
13.                 wordChecker += words[i];
14.  
15.                 if (i < (words.Length - 1))
16.                 {
17.                     wordChecker += "|";
18.                 }
19.             }
20.         }
21.  
22.         public bool VerifyClean(string word)
23.         {
24.             return !Regex.IsMatch(word, wordChecker);
25.         }
26.     }

 

where i put this code in a new C# ?

 

The CheckWords class would be a new C#. You'd call that script against the username they're trying to create, and create if it return true, otherwise you'd ask them to use a different username, without rude words.

 

this is my register and login script. Can i use it with it.

put it on button click reg compare typped name with the black list

 

I deleted my post because it was incomplete, I forgot to check bad words into the name, instead only the name. So use the function of the other guy in your code, just as another requirement like the lenght of the name.

I think he doesn't need to create another script, he can just add the function to that class and call it when neccesary.

 

What Mutur said

 

I would suggest using a hashtable like 'System.Collections.Generic.HashSet<string>' for faster lookup. Then segment the incoming 'username/word' into its possible words and test those. It'd be much faster for large lists.

Or rather, because they already have a mysql database, have a table in their of all bad words, and perform a lookup based on that.

Or interestingly enough you could use google:
http://thenextweb.com/google/2011/08/17/google-inadvertently-creates-a-profanity-api/#gref
Although really, this only does whole word testing...

Really all of these are naive profanity filters, if you google about implementing profanity filters a robust algorithm can get very complicated (avoid mentioning unity, that'll just limit your results... you can port most all implementations relatively easily. Especially if you find a C# implementation).

 

For my own knowledge.. Would you suggest against using Regex for finding patterns in strings? Is it slow?

 

Maybe have a table and pattern check for: Fvck a55 shi7 b1tch 0h y3ah h33 h33
