SOLVED: add number to int in a function

[Gepard]

How, I have this function that basically removes a certain item from a list.

   

Code: ags

function LoseQuest(String text){
	int p;
	while (p < quests.ItemCount){ //Change ListBox1 with the name of your listbox
	if (quests.Items[p].CompareTo(text, false) == 0){ //Change ListBox1 with the name of your listbox
	quests.RemoveItem(p); //Change ListBox1 with the name of your listbox
	PlaySound (10);
	return;
	}
	p ++;
	}
	}

I also have an int called "experience". Now what I wish to do is add the possibility not only write what quest (item) will the player lose but also how much experience will he get for it. Any idea how? Thanks.

Just add the xp the player gains as parameter to the function:

Code: ags

function LoseQuest(String text, int xp_gained) {     // ADDED int PARAMETER
	int p;
	while (p < quests.ItemCount) { //Change ListBox1 with the name of your listbox
		if (quests.Items[p].CompareTo(text, false) == 0) { //Change ListBox1 with the name of your listbox
			quests.RemoveItem(p); //Change ListBox1 with the name of your listbox
			PlaySound (10);

			experience += xp_gained;          // <------------ ADDED THIS LINE

			return;
		}
		p ++;
	}
}

Now call the function like this:

  LoseQuest("Tutorial", 20);

Hi. Thanks for the cod. Im having a problem with it as it wont compile:

First when I add exgain to integers:
---------------------------
Compile Error
---------------------------
'exgain' is a global var; cannot use as name for local.


Than without it:
---------------------------
Compile Error
---------------------------
Function declaration has wrong number of arguments to prototype.

So I do not know how to do it, although I know Im doing some silly mistake.

If exgain is a global variable then just name it differently 

Of course when you call the function you can put whatever variable you like as the parameter (like 'exgain').

EDIT: Now I see! I forgot to change the header of that function to match. Sorry guys.
