Currency Exchange System Explained

[Ravauvial]

This is the entire script as in TFS 8.54 Mystic Spirit.

changegold.lua Explained:

Now in data/actions/scripts/other/changegold.lua

function onUse(cid, item, fromPosition, itemEx, toPosition)

 <!-- 100 gold to 1 platinum -->
	if item.itemid == ITEM_GOLD_COIN and item.type == ITEMCOUNT_MAX then  <!-- This says check gold if max 100 -->
		doChangeTypeItem(item.uid, item.type - item.type) <!-- then change it to up note: 1 -->
		doPlayerAddItem(cid, ITEM_PLATINUM_COIN, 1) <!-- platinum coin = 1 -->
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_PLATINUMBLUE) <!-- print to screen in blue $$$ -->

 <!-- 100 platinum to 1 crystal -->
	elseif item.itemid == ITEM_PLATINUM_COIN and item.type == ITEMCOUNT_MAX then <!-- This says check platinum if max 100 -->
		doChangeTypeItem(item.uid, item.type - item.type) <!-- then change it to -->
		doPlayerAddItem(cid, ITEM_CRYSTAL_COIN, 1) <!-- crystal coin = 1 -->
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_TEAL) <!-- print to screen in teal $$$ -->
 <!-- Add new code 1 here -->

 <!-- This changes 1 platinum to 100 gold -->
	elseif item.itemid == ITEM_PLATINUM_COIN and item.type < ITEMCOUNT_MAX then <!-- This says check platinum if max 1 -->
		doChangeTypeItem(item.uid, item.type - 1) <!-- then change it to down note: -1 -->
		doPlayerAddItem(cid, ITEM_GOLD_COIN, ITEMCOUNT_MAX) <!-- This add 100 to player gold -->
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_YELLOW) <!-- print to screen in yellow $$$ -->

 <!-- This changes 1 crystal to 100 platinum -->
	elseif item.itemid == ITEM_CRYSTAL_COIN then <!-- This says check crystal if max 1 -->
		doChangeTypeItem(item.uid, item.type - 1) <!-- then change it to down note: -1 -->
		doPlayerAddItem(cid, ITEM_PLATINUM_COIN, ITEMCOUNT_MAX) <!-- This add 100 to player platinum -->
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_PLATINUMBLUE) <!-- print to screen in blue $$$ -->
 <!-- Add new code 2 here -->
	else
		return FALSE
	end
	return TRUE
end

so to add a new coin Scarab you need to add this:

Code 1

	elseif item.itemid == ITEM_CRYSTAL_COIN and item.type == ITEMCOUNT_MAX then
		doChangeTypeItem(item.uid, item.type - item.type)
		doPlayerAddItem(cid, ITEM_SCARAB_COIN, 1)
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_GREEN)

Code 2

	elseif item.itemid == ITEM_SCARAB_COIN then
		doChangeTypeItem(item.uid, item.type - 1)
		doPlayerAddItem(cid, ITEM_CRYSTAL_COIN, ITEMCOUNT_MAX)
		doSendAnimatedText(fromPosition, "$$$", TEXTCOLOR_TEAL)

You also need to change or add this to these files:

Go into data/global.lua
Near the bottom you will see this

ITEM_GOLD_COIN = 2148
ITEM_PLATINUM_COIN = 2152
ITEM_CRYSTAL_COIN = 2160

Now after the crystal coin add this:

ITEM_SCARAB_COIN = 2159

Now in data/actions/action.xml
find this:

	<!-- Change gold -->
	<action itemid="2148" event="script" value="other/changegold.lua"/>
	<action itemid="2152" event="script" value="other/changegold.lua"/>
	<action itemid="2160" event="script" value="other/changegold.lua"/>

and add one of these:

	<action itemid="2159" script="other/changegold.lua"/> <!-- Scarab Coin -->

Last but important to make NPC's see your new Money
Now in data/items/item.xml
you search for this:

	<item id="2159" article="a" name="scarab coin">
		<attribute key="weight" value="100"/>
	</item>

and add this:

	<item id="2159" article="a" name="scarab coin">
		<attribute key="weight" value="100"/>
this line --->	<attribute key="worth" value="100000000" />
	</item>

That is it should work great.

The items you can use are:

Christmas Token = 6527 or you can change it to Ivory Coin in Item.xml
Scarab Coin = 2159
Gold Nugget = 2157
Gold Ingot = 9971

I hope this helps everyone with the Currency exchange system

Just an FYI for anyone curious!

IF YOUR DISTRO DOESN'T HAVE A GLOBAL.LUA

Go to Data/LIB/000-CONSTANT

and thats where you will add

 ITEM_SCARAB_COIN = 2159

+rep if it helped you!
