How to edit NPC with scrolls (IK3_SCROLL)

[kaerusu]

Hello again. I am using some v18 (custom) files, and something I can't just finish to learn, it's that, how can I add the different kinds of scrolls to sell, in the old fashion way of course, when you edit like that:

AddVendorItem( 0, IK3_SCROLL, -1, 1, 1, 100 );
AddVendorItem( 1, IK3_SCROLL, -1, 3, 3, 100 );
AddVendorItem( 2, IK3_SCROLL, -1, 2, 2, 100 );

Some kind soul can explain me how can I put the scrolls in the shops like old v15, not with the "AddShopItem( 0, II_SYS_SYS_SCR_SMELPROT, 10000000 );" formula?

I really think I'm missing the key with the second number (1 or 2 or 3 in this case), or perhaps the last one (100 in this case), I don't know really; perhaps I can see some number or index in the specitem or in propitem? I really appreciate any help, any direction into the right way.

AddVendorItem(0(NPC tab), IK3_SCROLL(Items to sort), -1((-1 is all classes)<- Job required different vales results will very), dwItemRare(Lowest), dwItemRare(Max I believe 200 is cap), 30 (This shows how many items are displayed in the tab) )


in you're case find the item you want in specitems.txt
Crtl+F II_SYS_SYS_SCR_SMELPROT
now make sure dwShopAble is set to 1, dwItemRare is set to something like 200, make sure you set the dwCost keep in mind I believe there is minimum price you must set or you'll get an error in game when you try to purchase it.
Keep in mind I'm only displaying 199 - 200 dwItemRare items listed under IK3_SCROLL and it should only show you 20 in this Tab
AddVendorItem( 0, IK3_SCROLL, -1, 199, 200, 20 );


I'm kinda just going off old knowledge and a quick jump into the source since it's been ages and I'm not a dev take everything I say with a grain of salt.
Merge your character.inc and specitems, reload the world server and take a look?

Thank you again to bring some light into this matter. I think I'll try to edit the rarity then, and see what's the end of it.

With that source you can also use AddShopItem and just put the scroll and price directly into the character.inc file.
