[Add-On] Learning NPC scripts (beginner's guide)

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

@nCloud

the cm.haveitem part didn't have ( , ) , or { which you needed
Forgot a semi colon (

at the end of the sendSimple
Forgot to use \r\n#L0#text#l to show the selection. (I just changed it to YesNo)

\r\n = skip one line
#L0# = selection 0 (also #L1# would be selection 1, #L2# would be selection 2, etc.
#l = ends selection

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("Goodbye");    
            cm.dispose();    
            return;    
        }    
           
        if (mode == 1) {   
            status++;   
        }       
        else {   
            status--;   
        }   
           
        if (status == 0) {
		    cm.sendNext("Why, hello there my fellow ninja. It seems you may be in need of some throwing stars...");
	    }
	    else if (status == 1) {
            if (cm.haveItem(ILBI ID HERE,1)) {
			    cm.sendYesNo("Ah, it seems you already have some. Shame. Do you want some more?");
		    }
		    else {
			    cm.sendOk("Ummm, seems you could use some. Here, take these.");
			    cm.gainItem(ILBI ID HERE, 5);
			    cm.dispose();
			}
		}
		else if (status == 2) {
            cm.sendOk("These should help you with your hunting");
            cm.gainItem(ILBI ID HERE, 5);
            cm.dispose();
		}	
	}
}

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

Some questions quick questions

I'm noob sorry

Please explain what mode 1, 0, -1 does for me/

PHP:

        else {   
            status--;

What is the exact mode for this to occur ?

PHP:

var status = 0;   

function start() {   
    status = -1;

Why did you define variable status with the value of 0 and then instantly set it's value to -1 after.
Why is it -1 btw.

PHP:

    action(1, 0, 0);

Why is it 1, 0, 0

PHP:

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

Explain to me why is it >= 2 for status and why you need a return;

Hey everyone great guide but i'm having a bit of a problem...

function action(mode, type, selection) {
    if (mode == -1) {
        cm.dispose();
    } else {

            cm.sendOk("Friggin nib.");
            cm.dispose();
            return;

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

@ MrMysterious

You're looking for explanations to understanding the beginning of the script. Look for Clysse's guide on analyzing NPC scripts. There's a link of it in the release section

Why do I use this top?

When I first started learning java scripting I always began the beginning of my script the same way. It never failed me so I'm attached to using it

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

You can also add the "canHold" command which I found useful when you use the "gainItem" command.

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

@priest - As Xoti said, you have used cm.haveItem wrong.

This would work fine.

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("Alright, see you next time.");
			cm.dispose();
			return;
		}
		if (mode == 1)
			status++;
		else
			status--;
		if (status == 0) {
			cm.sendNext("Hi, I'm the Items Exchanger! ");
		} else if (status == 1) {
			cm.sendNextPrev("Click next.")
		} else if (status == 2) {
			if (cm.haveItem(2000005) {
				cm.sendNext("Great, you've clicked next");
			}
		} else if (status == 3) {
			cm.sendSimple("What would you like to exchange?\r\n#L0##bWizet Invincible Hat#l");
		} else if(status == 4) {
			if (selection == 0) { 
				if (cm.haveItem(2000005, 2000) {
					cm.sendOk("There you have it!");
					cm.gainItem(1002140, 1);
					cm.gainItem(2000005, -2000);
					cm.dispose();
				}
				else cm.sendOk("You do not have enough elixirs");	
				cm.dispose();
			}	
		}
	}
}

You only need to have an exact amount in you must have 2000 of 2000005 to obtain it. Even if you have more, your script is only going to take 2000 so this would work fine.

EDIT - Oh, I also noticed you double bracketed on the cm.haveItem commands , yours looked like this:
(cm.haveItem 2000005, 2000)) <---- You only need 1 )

wow thanks!but when it comes to this line:

Code:

                if (cm.haveItem(2000005, 2000) {

you need another ')' to close the code,is it?or it will just only close the '(' beside 2000005

Ah, I ment you only need the 1 ')' to close the '(' beside 2000005

i.e (2000005, 2000)

Glad I could help.
