Question about dynamic shop

    for(set [email protected],0; [email protected]<getarraysize(.customs); set [email protected],[email protected]+1) {
        for(set [email protected],0; [email protected]<getarraysize(@bought_nameid); set [email protected]d,[email protected]d+1) {
            if(@bought_nameid[[email protected]d]==.customs[[email protected]]) {
                if(checkweight(@bought_nameid[[email protected]d],@bought_quantity[[email protected]d])) {
                    if(countitem(.CoinID) >= .Price[[email protected]]*@bought_quantity[[email protected]]) {
                        delitem .CoinID,.Price[[email protected]]*@bought_quantity[[email protected]];
                        getitem @bought_nameid[[email protected]],@bought_quantity[[email protected]];
                    } else dispbottom "You don't have enough "+getitemname(.CoinID)+" to purchase that item.";
                } else dispbottom "Purchasing these items will put you over the weight limit!";
            }
        }
    }
    deletearray @bought_quantity, getarraysize(@bought_quantity);
    deletearray @bought_nameid, getarraysize(@bought_nameid);
    close;

OnInit:
    setarray .customs[0],12028,607,678;// Enter the ID of customs here
    setarray .Price[0],10,3,5; // Price for each custom is set to 20 coins
    set .CoinID,7539; // Enter the ID of the coin here.
    npcshopitem "custom_seller2",0,0; // Don't touch any coding beyond here
    for(set .i,0; .customs[.i]; set .i,.i+1) npcshopadditem "custom_seller2",.customs[.i],.Price[.i];
    end;
}

 

My question is:

this line mes ""[email protected]_nameid[[email protected]]+""; shows the correct name when a item is bought

this line    mes ""+.Price[[email protected]]+""; doesn't show the right price. its always Price[0]

why? isn't [email protected] supossed to be a npc variable after the bought?

[email protected] is the loop variable set by this :

Quote

 for(set [email protected],0; [email protected]<getarraysize(@bought_nameid); set [email protected],[email protected]+1) {

so anywhere above that it is zero. However if you bought only one item at a time, then @bought_nameid [0] does reference that item correctly. Otherwise it'll only show the first, as it's displayed outside the loop.

furthermore, the loop finds you which item in your Price array was bought - and that's in [email protected] So the correct price is .Price[[email protected]]  and again, only inside the loop, below the

Quote

 if(@bought_nameid[[email protected]]==.customs[[email protected]]) {

Line which ensures the variable [email protected] has the correct number.

Oh i see, thanks! i thought it was a variable from bought_x functions.
