Once again in the interest of education, here's my shop system. It's broken into several parts, so make sure to read the instructions carefully!
Now, of course you can modify the script to make it match your own setup, however, here's how it works in my configuration. It also works using gralats by default; you'll have to change it in order to use custom money.
You'll need to update the shop weapon so that it adds the item to the player matching your own system. Also, you'll want to make sure that the seteffect fade doesn't interfere with your daynight, and finally, note that the weapon has a "Debit" option. This was for my setup on Rudora so that you could pay straight from your bank account. Either match it to your own bank system or just rip it out.
The system will depend upon three database NPCs, two classes and one weapon. Start by making the Database NPCs;
- DB_Items; this is where we will store information about the items which you will sell
- DB_Shops; this is where we will store the names of the shops, funds received from shop sales, etc
- DB_Prices; this is where we will store the prices of items
You'll need to populate the NPCs with some data. Let's start with DB_Items; put the following script in DB_Items:
PHP Code:
function onCreated()
{
/*
Format:
this.item_id = {Name, Internalname, Image, ActionWeapon, Canbedropped};
*/
this.item_100 = {"Block", "block", "block.png", "-No Item", 1};
}
Next, in DB_Prices, put the following:
PHP Code:
function onCreated()
{
// Format:
// this.item_id = price
this.item_100 = 3; // 3 gralats in this case
}
Next, you'll need to set up the levels with the classes. It shouldn't really matter what you name the classes, but for this example, we'll use 'shopcontrol' and 'shopitem'.
Each shop level requires one shopcontrol class. This puts the level's base name into a level variable, and displays the shop's funds and name. Put this somewhere nice-looking. Just do something like this:
PHP Code:
this.join("shopcontrol");
Now, for each item that you want to sell in the shop, place a shopitem. You must specify additional data for shopitem classes, such as the item you want to sell. Here's an example:
PHP Code:
this.item = 100; // this is item ID 100 from DB_Items
this.customimage = false; // use the image set in DB_Items
this.join("shopitem");
Finally, add the shop interface weapon into a weapon called "-Shop", and make sure that it is added to any players using the shop. Hell, you could just add it to all players on logon.
That's about it, really. Once you upload the shop, it should work. You should also be able to specify a name for the shop inside DB_Shops' flag list once it's uploaded.
Enjoy.
Shop item class:
PHP Code:
function onCreated()
{
onTimeout();
}
function onTimeout()
{
this.okay = 0;
if (this.item == NULL)
{
temp.data = "-unavailable-";
}
if (DB_Items.("item_" @ this.item) == NULL)
{
temp.data = "-unavailable-";
}
if (DB_Prices.("item_" @ this.item) == NULL)
{
temp.data = "-unavailable-";
}
this.itemdata = DB_Items.("item_" @ this.item);
this.price = DB_Prices.("item_" @ this.item);
this.setShape(1, 32, 32);
if (temp.data == "-unavailable-")
{
this.setimg(""); // <- image for unavailable item here
}
else
{
if (this.customimage != TRUE ||
this.customimage == 0)
{
this.setimg(this.itemdata[2]);
}
}
if (temp.data == NULL)
{
temp.data = this.itemdata[0];
this.okay = 1;
}
showimg(1, "@Tahoma@bc@" @ temp.data, this.x + 1, this.y - 0.5);
changeimgzoom(1, 0.5);
setTimer(2);
}
function onActionleftmouse()
{
if (this.okay == 1)
{
player.triggerclient("-Shop", "purchaseItem", this.item, this.itemdata, this.price);
}
}
Shop control class:
PHP Code:
function onCreated()
{
level.creditor = extractfilebase(this.level.name);
onTimeout();
}
function onTimeout()
{
level.shopname = (!(DB_Shops.(level.creditor @ "_name")) ?
"Unnamed Shop" : DB_Shops.(level.creditor @ "_name"));
showimg(1, format("@Tahoma@bc@%s", level.shopname), x - 1.5, y - 1);
changeimgvis(1, 2);
changeimgzoom(1, 0.8);
showimg(2, format("@Tahoma@bc@Shop Funds: %ig", DB_Shops.(level.creditor @ "_funds")), x - 1.5, y);
changeimgvis(2, 2);
changeimgzoom(2, 0.5);
setTimer(2);
}
-Shop weapon:
PHP Code:

return;
}
if (DB_Prices.("item_" @ params[1]) == NULL)
{
player.say2("An error occured. 2");
return;
}
temp.price = DB_Prices.("item_" @ params[1]);
temp.item = params[1];
temp.creditor = (!level.creditor ? "unknown" : level.creditor);
if (params[2] == false)
{
if (player.rupees >= temp.price)
{
player.rupees -= temp.price;
// ADD THE ITEM TO THE PLAYER HERE
DB_Shops.(temp.creditor @ "_funds") += temp.price;
player.say2("Thank you.");
}
else
{
player.say2("You do not have enough money!");
}
}
else
{
if (player.bankBalance() >= temp.price)
{
temp.res = player.bankDebit(temp.price, temp.creditor);
if (temp.res == 0)
{
// ADD THE ITEM TO THE PLAYER HERE
DB_Shops.(temp.creditor @ "_funds") += temp.price;
player.say2(format("Thank you.\nDebited: %dg.\nNew bank balance: %dg.", temp.price, player.bankBalance()));
}
else
{
player.say2(format("Bank debit failed!\n%s.", temp.res));
}

player.say2("You do not have enough money!");
