[Trigger] Selling items from a shop for other items

[Flitty]

I want to have the purchase cost of certain items to be other lower tier items, how would I go about triggering this?

I believe that what you mean is, for an exaple:
Buying Claws of Attack +3 requires, let's say, Claws of Attack +2 and some gold, correct?

If so, the trigger is quite simple, but kinda long to write. I myself would do it with hashtables, saving Tier 1 item at index 1, then Tier 2 item at index 2 and so on. Then, when an unit wants to buy an item, the trigger checks whether it has the lower tier item in it's EQ and either removes the lower tier item or shows an error message and doesn't allow to buy the item.

It's 2:25 AM in my country, sorry for not-too-understandable way of putting things

yes this is what I meant. thinking about it i could simply just have a trigger for when the unit aquires the item, if they have the required items/gold then remove them or if they don't then remove the sold item. the only (minor) issue is the shop stock, can i reset the cooldown/stock of an item via triggers?

Well, about stocks.

To my mind, there's no way to check how many items there are in stock, maybe by some custom functions, neither is there a way to add simply one item, i believe.

You can experiment with this:

AddItemToStock:

native AddItemToStock               takes unit whichUnit, integer itemId, integer currentStock, integer stockMax returns nothing

It gives whichUnit the itemId to stock with currentStock number and makes it never recharge above stockMax. Maybe it is a bit different, but I used it only in a manner of adding one item to a shop with 1 stock and stock max of 1, so I don't have much experiece in 'the field'.

Still, I whish you good luck with it.

Use a recipe system and instead of gold make the players buy an upgrade item then the recipe will be complete and the item will be upgraded. There is an item recipe system in my sig.
