[Solved] How to detect String?

[xorkatoss]

Hello guys I need some help in GUI with detecting script anywhere in a chat message.

let's say I type the sentence "This is a test string"

If I want to detect the word "test" I use this:

• (Substring((Entered chat string), 11, 14)) Equal to test

then this action is successful BUT what If I want to detect it anywhere on a chat?

example:
I have the sentence "This test is a string"

In this case the above trigger will not work, I tried finding a solution to this under
"Conditions - String Comparison" but no luck there...


so does anybody know if it's possible to detect strings anywhere on a chat message??

I think @TriggerHappy worked on a string iterator but it's in vJASS.

Edit:

Sorry, its' actually @LeP who has the utf8-aware iterator.

Basically, what that library does is iterate through a string.

ok so I guess that solves my question, there isn't a way to do it in GUI without using a different system...thanks for the help!

It's also possible in GUI. Check out the attached demo.

• String Find
  • Events
  • Conditions
  • Actions
    • Set STRF_Text_Position = -1
    • Set STRF_Length_Read = (Length of STRF_Text_ToRead)
    • Set STRF_Length_Find = (Length of STRF_Text_ToFind)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • STRF_CaseSensitive Equal to False
      • Then - Actions
        • Set STRF_Text_ToFind = (String(STRF_Text_ToFind) as Lower case)
      • Else - Actions
    • For each (Integer STRF_i) from 1 to STRF_Length_Read, do (Actions)
      • Loop - Actions
        • Set STRF_Substring = (Substring(STRF_Text_ToRead, STRF_i, (STRF_i + (STRF_Length_Find - 1))))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • STRF_CaseSensitive Equal to False
          • Then - Actions
            • Set STRF_Substring = (String(STRF_Substring) as Lower case)
          • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • STRF_Substring Equal to STRF_Text_ToFind
          • Then - Actions
            • Set STRF_Text_Position = STRF_i
            • Set STRF_i = (STRF_Length_Read + 1)
          • Else - Actions

• Demo
  • Events
    • Player - Player 1 (Red) types a chat message containing <Empty String> as A substring
  • Conditions
  • Actions
    • Set SomeText = (Entered chat string)
    • -------- Setup variables and run find trigger --------
    • Set STRF_Text_ToFind = test
    • Set STRF_Text_ToRead = SomeText
    • Set STRF_CaseSensitive = True
    • Trigger - Run String Find <gen> (ignoring conditions)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • STRF_Text_Position Not equal to -1
      • Then - Actions
        • Game - Display to (All players) the text: (Found at position: + (String(STRF_Text_Position)))
      • Else - Actions
        • Game - Display to (All players) the text: Text was not found

You can set the both string variables:

• Text_ToRead
• Text_ToFind

and define if you want it to have case sensitive, or not:

• CaseSensitive

(not case sensitive will not care if written in upper or lower case)
And then run the StringFind trigger. After running you can compare the "Text_Position" integer:

• If "Text_Position" equals -1 means text was not found
• .. else it does tell you the position where the string was found

In the demo it will watch what Player 1 writes and will search for "test" string and case sensitive.
