Check a string variable for key words

Hi, I am currently making an npc system and using string variables to input text.

So what I need is to also use the same string variable to call an avatar image while the npc is speaking. The string variable may look like this:

"(av:james) Hi my name is james"

Basically I need to tell construct to not print out the part of the string variable that defines the avatar(av:james). And at the same time use (av:james) as a condition to display the avatar of the character james.

Is it possible to make construct check a string variable for a keyword and if it's in the string variable, to remove it from the printed text.   <img src="smileys/smiley1.gif" border="0" align="middle" />

look at tokenat()

Hi, can you elaborate a little bit more? I am still learning this

:)

I was thinking of using the find() expression but couldnt find any examples of that in action.

TokenAt() is a good way to do that. Then C2 manual say:

tokenat(src, index, separator)

Return the Nth token from src, splitting the string by separator. For example, tokenat("apples|oranges|bananas", 1, "|") returns oranges.

tokencount(src, separator)

Count how many tokens occur in src using separator. For example, tokencount("apples|oranges|bananas", "|") returns 3.

So, rather than "(av:james) Hi my name is james" you might just want to have "james|Hi my name is james"

then tokenat("james|Hi my name is james",0,"|") will return the avatar, and tokenat("james|Hi my name is james",1,"|") will return the text for him to say.

You can chain together strings, using different tokens if you want.

"james|Hi my name is james#susan|Hello there!#ben|Good day, eh?"

just be sure to use tokens that wont appear in your text, or if you are going to pass the strings to php (to save in a database) don't use a symbol that may cause trouble there (like "&")

I'm glad that AllanR answered before me - I never knew about chaining them together.

Every day I learn something new - I just wish I could remember it all !

This is super awesome!! Much rep to you sir. :)

What a great solution. And thank you for taking the time to explain how tokens work <img src="smileys/smiley12.gif" border="0" align="middle" />
