cm.gainItem(4000313, -1);
cm.dispose();
}
}
}

        if (status == 0) {
            cm.sendAcceptDecline("Here's a Beta #t1002518, you only get one, so take care of it!");
        }
    else if (status == 1) {
        if(cm.haveItem(1002518)) {
        cm.sendOk ("You already have a #t1002518 I'm not stupid!");
        cm.dispose ();
    }
    else {
        cm.sendOk("Here's your #t1002518# and some Mesos & NX! Good luck on your adventure!");
        cm.gainItem(1002518, 1);
        cm.gainMeso(10000);
        gm.gainNX(10000);
        cm.warp([000040000], [0]);
        cm.dispose();

    }



    }

    }

}
Instant d/c when you click the npc, any help? I can't see what I did wrong, when I compare to the guide. Please try to explain what I did wrong, don't just correct it. :)

Very nice guide, easy to follow.

Re: [Tut] Learning NPC scripts (beginner's guide)

@ calvin21

To take an item away just change the number in the cm.gainItem to a negative.

Script your NPC and put the .js into your npc folder in the repack. Rename it whatever your NPC id is. Then you can use !pnpc to permanetly place the NPC somewhere.

Re: [Tut] Learning NPC scripts (beginner's guide)

@vincenty2x2

PHP: 
if (cm.getParty().getMembers().size() > 3 || party.size() < 6) {

If the party is the size of more than 3 and less than 6...

Got this out of ThePack's script

Re: [Tut] Learning NPC scripts (beginner's guide)

Let's say I wanted a GM roar teacher NPC, would I use this?

Code: 
var status = 0;

function start() {
    status = -1;
    action(1, 0, 0);
}

function action(mode, type, selection) {
    if (mode == -1)

            cm.dispose();
        if (mode == 1)
            status++;
        else
            status--;
        if (status == 0) {
            cm.sendSimple("Hello, I can teach you the skill GM Roar.\r\n#L1# I would like to trade in 15,000 #b#v4001024##k for GM Roar!#l\r\n\#L2# I would like to trade in 750 #b#v4000352##k for GM Roar.#l");
        } else if (status == 1) {
            if (selection == 1) {
                if(cm.haveItem(4001024,15000)) {

Re: [Tut] Learning NPC scripts (beginner's guide)

@ iDevil

You're a great scripter! You're just missing a couple things here and there. You don't do an }else{ at the bottom of the script. I know that you're trying to make an option for end chat.
PHP: 
var status = 0;  

function start() {  
    status = -1;  
    action(1, 0, 0);  
}  

function action(mode, type, selection) {  
    if (mode == -1) {  
        cm.dispose();  
    }  
    else {   
        if (status >= 2 && mode == 0) {   
            cm.sendOk("See you later!"); // end chat
            cm.dispose();   
            return;   
        }    
        if (mode == 1) {  
            status++;  
        }      
        else {  
            status--;  
        }  
        if (status == 0) { 
            cm.sendSimple("Hello, I can teach you the skill GM Roar.\r\n#L1# I would like to trade in 15,000 #b#v4001024##k for GM Roar!#l\r\n\#L2# I would like to trade in 750 #b#v4000352##k for GM Roar.#l");
        } else if (status == 1) {
            if (selection == 1) {
                if(cm.haveItem(4001024,15000)) {
                    cm.teachSkill(5001001,1,1);
                    cm.gainItem(4001024,-15000);
		            cm.changeJob(900);
	                cm.sendOk("You have learned GM Roar! Congrats! If you did not learn GM Roar please contact a GM.");
	                cm.dispose(); // You need cm.dispose();

		            cm.dispose();
	        } 
            else if (selection == 2) {

PHP: 
if (cm.getParty().getMembers().size() > 3 || party.size() < 6) {

If the party is the size of more than 3 and less than 6...

Got this out of ThePack's script
Click to expand...

And how do you make it check if they are lvl 120-180?

PHP: 
if (cm.getParty().getMembers().size() > 3 || party.size() < 6 && cm.getLevel() >= 120 =< 180 ) {

This way?

Oooh,the getLevel function made the server crash :&

Re: [Tut] Learning NPC scripts (beginner's guide)

var status = 0;

function start() {
status= -1;
action(1, 0, 0);
}

function action(mode, type, selection) {

if (mode == -1) {
cm.dispose() ;
}
else {
if (status >=2 && mode == 0) {
cm.sendOk("Goodbye") ;
cm.dispose() ;
return;
}

if (mode == 1) {
status++;
}
else {
status--;
}

if (status == 0) {
cm.sendSimple("Hey, wanna buy special items. \r\n#L0#wizet hat#l \r\n#L1# super uber weapon.#l") ;
}
else if (status == 1) {
if (selection == 0) {
if (cm.haveItem(4031543, 500) ) {
cm.gainItem (4031543, -500) ;
cm.gainItem (1002140, 1) ;
cm.dispose() ;
}
}
else {
cm.sendOk ("come back when you have enough ticks")
cm.dispose() ;
}
else if (status == 1) {
if (selection == 1) {
if (cm.haveItem(4031543, 500) ) {
cm.gainItem (1472051, 1) ;
cm.gainItem (4031543, -500) ;
cm.dispose() ;
}
}
else {
cm.sendOk ("come back when you have enough ticks")
cm.dispose() ;
}
}
}
}

Re: [Tut] Learning NPC scripts (beginner's guide)

this is a good guide for some people but for beginners, they have no idea what level 1 stuff is, you should have got into depth about the status and whatnot

Re: [Tut] Learning NPC scripts (beginner's guide)

@ beebeewawa

it should be else if (selection == 1) {

@ vertskater12

Thanks for the advice. Level 1 is very short and really only introduces the beginning of a script. I chose not to go indepth with "the status and wahtnot" because I want this script to teach how to code well. There's indepth explanations in other guides if you really want to get one.
