action triggered by keywords

silly title perhaps but what I ment is I normaly can do like say something like hello and the script does some action but saying like hello there doesn't work..

my question is how to make a piece of code that reacts on keywords

hope that makes some sense..

in your listen event use if else statements

ie:

listen(integer channel, string name, key id, string message)
{
     if (message == "hello") llSay(0,"hello " + name);
     else if (message == "red") llSetColor(<1,0,0>,ALL_SIDES);
     else llSay(0,"invalid command");
}

well its what I kinda am doing but I have to write that certain word and what I like to do is having a line like.. hey you hello there and have the script handle the word hello in that line no matter where placed... as far it works no I have to write hello... nothing before or after that word

hope that clears it up a lil, thanks none the less

oh well 2 options

llGetSubString which takes a predefined chunk of a string and makes it into its own element

and llSubString Index, which in this case would need llGetSubString too, but it allows you to seach the string for a pattern and return the position of it

ie

integer x = llSubStringIndex(message," " - 1);
if (llGetSubString(message,0,x) == "hello" do stuff
