[General] Items being bought with different forms of currency?

[Denny]

This is probably simple to some of you, but I can't quite figure out this on my own.

How do you buy an item from a shop, using (lets say for my purposes) a gem?
You have the gem in your inventory, and you want to buy an awesomely-uber-cool weapon only exchangeable through gems.

And for those really smart, how about you want to buy an overlyexcessivedescriptiveword piece of armor, only exchangeable through two types of gems, say an opal and a topaz.

Regards.

Triggering:

• Trigger
  • Events
    • Unit - A unit Sells an item (from shop)
  • Conditions
    • (Item-type of (Sold Item)) Equal to (your item)
  • Actions
    • Set tempUnit = (Buying unit)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (tempUnit has an item of type Gem) Equal to False
      • Then - Actions
        • Item - Remove (Sold Item)
      • Else - Actions
        • Item - Remove (Item carried by tempUnit of type Gem)

And for the item that requires 2 gems:

• Trigger
  • Events
    • Unit - A unit Sells an item (from shop)
  • Conditions
    • (Item-type of (Sold Item)) Equal to (your item)
  • Actions
    • Set tempUnit = (Buying unit)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (tempUnit has an item of type Gem) Equal to False
      • Then - Actions
        • Item - Remove (Sold Item)
      • Else - Actions
        • Item - Remove (Item carried by tempUnit of type Gem)
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (tempUnit has an item of type Gem) Equal to True
          • Then - Actions
            • Item - Remove (Item carried by tempUnit of type Gem)
          • Else - Actions
            • Hero - Create (your item) and give it to tempUnit

Wow, thank you very very much. I have one more question if you don't mind, what should I classify the items that are bought with gems as? Because I don't want it to be bought with gold whatsoever, or even have the option of being bought with gold.

 

[Mr_Bean]

Doesn't matter. Just set the gold cost for each item to 0.

 

[Arisato]

And make it check whether the amount of gem is sufficient.

@Bean
If you need 2 gems, why don't you use ItemCounter of Integer variable ?
By looping each slot in the inventory of the unit, you can retrieve how many Gems the unit has.
What if the item needs 3 gems instead ?

I'm quite unsure on your approach, and I'm not saying yours is wrong.
Maybe because you have a different approach, just curious.

 

[Mr_Bean]

Your approach is probably better. With mine, it remove on gem from the hero and checks whether they have another gem.
