Price Changing

[friend]

I remember I saw one topic in a forum ( Can't remember which) that gives me a call script code to change prices. Can anyone either give me the code or have another alternative? Cause I want different prices for different towns. :cheers:

Try this...

  #-----------------------------------------------------------------------------

  def price

    if $game_system.is_a?(Game_System) && $game_system.item_price.has_key?(id)

      return $game_system.item_price[id]

    end

    changeprices_rpgitm_price

  end

end

 

#===============================================================================

    end

    changeprices_rpgwpn_price

  end

end

 

#===============================================================================

      arr = Array.new

Using a simple call script, I tested it so it works fine, it aliases the price method of RPG Item, Armor and Weapon and is saved through $game_system. You can also reset your prices too. I've made a couple call scripts to test the system, here's how you do it.

To change prices of things...

gs = $game_system

gs.item_price[1] = 420

gs.armor_price[1] = 420

gs.weapon_price[1] = 420

To reset prices to default (whats defined in database), do...

gs = $game_system

gs.reset_item_prices

gs.reset_armor_prices

gs.reset_weapon_prices

Note, when resetting prices to items or other, you can use an array of numbers (ie, [1, 2, 3, 9, 11]) to reset only those items to their default prices specified in the database, same for armors and weapons. If you don't specify an array, it'll automatically clear ALL custom prices set in game back to the default database prices.

This will corrupt saved games (which means just don't try to load any old save files), meaning these prices will be saved and loaded from your save file.

Enjoy :thumb:

you don't have to do scripts for that . Just go to "Tools-> Database -> Items" select item and change it's price...

@Kain: thanks

@surengin: Please read the whole post before trying to reply. Changing the price in the database is a fixed one. Scripts allow you to change it midgame.

Woops! Sorry ^^

You don't need a script. You can just copy every item and change the price. You can add to your notes for which town the items are for.

 

[MCsephiroth13]

But if your item is in your inventory, then it will still have the same item for the same price. Why is everyone here so against using a script for this?

Not to mention that you'll have multiple copies of items in your inventory.

Maybe becouse we don't know scripts ... Unlike you.

 

[Cryranos]

You add the script to the script manager above main and then call the script from the event.

You don't have to know scripting to do that.

 

[surengin]

And how do i create script?

You think I know scripts!? Ha! If there was one person in the whole world who didn't know scripts, it would be me. I just said that because scripts indeed make your life easier sometimes and can be much cleaner than eventing.

 

[surengin]

okey , sorry for being mean , so how to add new script
?

 

[MCsephiroth13]

You weren't being mean, I just had to announce that I can't script for shit. XD

 

[surengin]

xD so do you know how to add new script?

 

[MCsephiroth13]

Normally you would paste it above Main in the Script Editor (F11).

By the way, why are you asking that in this thread?

 

[surengin]

because in my no one ever answers my questions , and if they do , they answer wrong...
