[General] Simple Shop System

[blancfaye7]

Hello again, Hive.

I am planning to make a simple Shop System where items bought by a buyer will be automatically bought by other units surrounding the buyer with the corresponding costs.

I just don't know how to detect the unit that is targeted by the shop.

I also have a question of what is the proper way of doing this. Storing the buyer to a variable won't work, but there can be an instance where there are more than 1 players who are going to be in the shop, or one or more units of a player can go into different shops.

Thanks!

Detect when a unit acquires an item.

How to differentiate between buying and picking up items?

First trigger detects when an item is sold, saves that to a temp variable. "unit sells an item" fires before "unit acquires an item".
Second trigger will give you which unit bought it.

Thank you so much.

EDIT:

How do I get the cost value of an item (gold and lumber) in triggers?
If that's not possible, then how do I force a unit to buy from a shop?

You'll have to save the costs of each item in an array or hashtable, then retrieve it when you want to make these purchases.

I was afraid that you were going to say this. x'D

I have no experience in Hashtables. I will look for some tutorials. What really confuses me was the index (?) of a hashtable.

An array will do fine.

Setup:
set ItemType[1] = crown of kings
set ItemCost[1] = 500
set ItemType[2] = blades of attack
set ItemCost[2] = 200
set ItemMax = 2 (the highest array number from the list)

On purchase:
for loop Integer_A from 1 to ItemMax do:
if item type of item being manipulated equal to ItemType[Integer_A] then set temp_cost = ItemCost[IntegerA]

You can try an easier method if you have lots of items. http://www.hiveworkshop.com/forums/...-0-1-0-a-245280/?prev=search=cost&d=list&r=20

I might make a GUI one later.

The system is extremely useful, but I'm having second thoughts about this...
(I am definitely stupid to know what;s going on in the system you linked).
IF you are going to make the GUI one

The hash tables will do fine as suggested, but I do have a lot of items...

I have reimplemented my Bulk Buying System into Array format since my last hashtable had bugs due to lack of knowledge of hashtables.

Then, I suddenly realized that I have not implemented (even in hashtables) detecting the stock amount of the item. How do I get the remaining stock value of the item in shop?
