Syntax

• callfunc "<function>"{,<argument>,...<argument>};
• callfunc("<function>"{,<argument>,...<argument>});

Description

This command lets you call up a function NPC. A function NPC can be called from any script on any map server. Using the 'return' command it will come back to the place that called it.

You can pass arguments to your function - values telling it what exactly to do - which will be available there with getarg() (see 'getarg') Notice that returning is not mandatory, you can end execution right there.

If you want to return a real value from inside your function NPC, it is better to write it in the function form, which will also work and will make the script generally cleaner.

Examples

	place,50,50,6%TAB%script%TAB%Woman%TAB%115,{
		mes "[Woman]"
		mes "Lets see if you win";
		callfunc "funcNPC";
		mes "Well done you have won";
		close;
	}
	function%TAB%script%TAB%funcNPC%TAB%{
		if(rand(2)) return;
		mes "Sorry you lost";
		end;
	}

	place,50,50,6%TAB%script%TAB%Man%TAB%115,{
		mes "[Man]"
		mes "Gimme a number!";
		next;
		input .@number;
		if (callfunc("OddFunc",.@number)) mes "It's odd!";
		else mes "It's even";
		close;
	}
	function%TAB%script%TAB%OddFunc%TAB%{
		if (getarg(0)%2) return 1; // it's odd
		return 0; // it's even
	}
