Hey, love the script, but I was looking and I did't find where I put the items on the shop, or the value for them, can you show me, please?

[Random Items at Random Prices]

Hi, I'm really really new at programing, and I was wonder if anyone could help me with this:
I'm looking to make an NPC who sell 10 random items at random prices, but I want to chose all itens he can sell and the range price for every item. And he reset the sells every 12h and announce that are new itens available for the server. Something like:
 

Item pool: 

itemID/zeny (random at range):

756 /  500z - 1,000z

1260/ 1,000,000z - 2,500,000z

 2609/ 1,000z - 1,500z

4110/ 2,000,000z - 2,300,000z

13404/ 3,000,000z - 3,200,000z

4435/ 5,000,000z - 7,000,000z

 

And then the NPC sell:

itemID/Zeny

756/ 650z

13404/ 3,119,020z

2609/ 2,956,126z

 

Thanks in advance for anyone who look at this!

[Weekly item sale npc]

Hey, sorry for ressurect this post, but a lot of times, my itens are set to 0

OnInit:
    //ITEM ID or #CASH/#PVPPOINTS
    set .Currency$,"Zeny";
    //TOTAL ITEMS YOU WANT TO SEE IN THE SHOP- MAKE SURE THAT ITS COUNT IS LOWER THAN ITEMLIST
    set .TotalShopItems,5;
    //DAYS YOU WANT TO RESET at TICK Time 12:00AM e.g 0= Sunday, 1=Monday, 2=Tuesday and so on.
    setarray .Days[0],0,1,2,3,4,5,6;
    //TIME TICK BY HOURS. e.g 1= 1am, 8=8am, 14=2pm.
    setarray .Time[0],0,4,8,12,16,20;    //12am,4am,8am,12pm,4pm,8pm
    //ITEMS LIST FOR RANDOM ITEMS SALE
    setarray .ItemLists[0],501,502,503,504,505,506,507,508,509,510,511,512;
    //COST OF ITEMS
    setarray .ItemCost[0],5000000,1000000,15000000,20000000;
end;
}
-    shop    Item_Sale    -1,501:100

 

Ok, I figure it out. The quantity of values in .setCost cannot be lower then the quantity of items on .ItemList, they have to bem proportional 1:1 (One item for one price), but this happens even if I put the .ItemCoast to rand, and I think this have relation with this part:
 

OnChangeItems:
	for(.@i=0;.@i<.TotalShopItems;.@i++){
		.rand = rand(getarraysize(.ItemLists));
		for(set .@l,0;.@l<.TotalShopItems;set .@l,.@l+1){
			if(.ItemLists[.rand]==.ShopItem[.@l]){
				.rand = rand(getarraysize(.ItemLists));
				set .@l,-1;
			}
		}
		sleep2 100;
		set .ShopItem[.@i],.ItemLists[.rand];
		set .ShopCost[.@i],.ItemCost[.rand];

Or this one:
 

function	CheckCost	{
	if( getitemname(atoi(getarg(0)))!= "null" ){
		if(countitem(atoi(getarg(0)))< getarg(1) ) return 1;
	}else{
		if(getd(getarg(0))< getarg(1)) return 1;
	}
return 0;
}

But I don't have enough knowledge yet to resolve this. If I do it, I'll be putting in here.

 

Hey, I did it

Now the NPC will get random values bethween the min and max price for individual items.
