buying stuff from npc

[Joe]

my character needs to buy supplies from an npc who sells several items.  

so far for the npc character i have

if user clicks inventory item on the npc
and if that item is money
  then run a dialog (dialog being the choices of merchandise)
 
and then im stuck...

i need game to recognize that if i choose first dialog choice, give me the first item, if second dialog choice, 2nd etc.  

not sure how to proceed.  if there is a tutorial on this just give me link and ill work it out.

Have you ever scripted a dialog before?
If not, be sure to read up on "Conversations" in the manual.

I think the add-inv X (X=inventory item number) command is what you're looking for.

nope.  but it doesnt seem all that hard. ill try what you said and post how it went in a lil while.

ahha thanks i was looking at it wrong, trying to see which dialog user choose from npc's 'interaction' properties...instead of just adding your line to the actual dialog script.  

it works!  thanks.

Cool.
Just for future reference, in case you want to do more advanced stuff from dialogs, here's how to do it:

Code: ags

// dialog script

@1 // buy item 1
ego: Gimme that thing there!
guy: No prob. Here you go...
run-script 1
return

@2 // buy item 2
ego: I want this over there!
guy: Sure. Here you go...
run-script 2
return

@3 // buy nothing
ego: That's all, thanks.
guy: Bye.
stop

Code: ags

// global script (menu "Script", "Edit global script...")

function dialog_request (int parameter) { // add this function if it's not there

  if (parameter == 1) { // called by run-script 1
    AddInventory(1); // give player inventory item 1, same as add-inv 1
    // put more advanced stuff here, animations and such
  }
  else if (parameter == 2) { // run-script 2
    AddInventory(2); // give player inv item 2
    // more stuff here
  }
  // ...etc., put as much else-ifs here as you need

}
