parse a chat message

[Grundy]

i tried looking on here but im not sure what exactly to search for and the search thing is pretty useless if you dont know what to search for.

how do you parse an entered text message from a player?

like in some maps where they have
-give 1 40
where it would give player 1 40 of your gold

i'm guessing the event would start with this event:
Player - Player X (Color) types a chat message containing -give as A substring
but then what triggers do you use to check what was typed after -give?

Ya, correct start. Events will have that for ALL players though, and the trigger sorts it out.

Then use the substring again to determine values.

You can do this using:
-Plain variables, could run intro problems in multiplayer. Probobly not, for the trigger wont take much time at all, but hey.

-A local variable to store the ammount in. Being local, multiple people can use the trigger at once.

-repetive code, (no variable, and having the substring statement 20 times.)

And it would look like this (plain variables):

Actions
    Set Give_Player = (Integer((Substring((Entered chat string), 7, 7))))
    Set Give_Gold = (Integer((Substring((Entered chat string), 9, 12))))
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            Give_Gold Greater than or equal to 1
            Give_Player Less than or equal to 12
            Give_Gold Less than ((Triggering player) Current gold)
        Then - Actions
            Player - Add Give_Gold to (Player(Give_Player)) Current gold
            Player - Add (Give_Gold x -1) to (Triggering player) Current gold
        Else - Actions
            Do nothing

Now, substring only works with the two numbers to chop the string. So you may have a problem if you have 10+ players, because thats 2 characters.

So then you'll need to say -give 01, -give 02, -give 10, etcetera instead of -give 1

You could always test for a " ", if there is one, cut out 1 character, otherwise 2.
More work, but it's also more userfriendly.

well the thing im trying to do here is add dueling to my hero map, i dont want the typical periodic duels between random heroes. i only want people to duel who want to duel so i want to make a challenging system where one player would challenge another to a duel.

im at school so the text wont be exactly right but would you do this

Events
    Player 1 enters -duel as a substring
    Player 2 enters -duel as a substring
    Player 3 enters -duel as a substring
    Player 4 enters -duel as a substring
    Player 5 enters -duel as a substring
    Player 6 enters -duel as a substring
    Player 7 enters -duel as a substring
    Player 8 enters -duel as a substring
    Player 9 enters -duel as a substring
    Player 10 enters -duel as a substring
Actions
    Set Challenger = (Triggering player)
    Set Defender = player((Integer((Substring((Entered chat string), 7, 7)))))
    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        If - Conditions
            Challenger is an enemy of Defender equal to true
        Then - Actions
            Trigger - Run start duel <gen>
        Else - Actions
            Do nothing

where the start duel trigger starts the duel between the challenger and the defender
