multiple currencies script question

[Kaoii]

I want to apologize first if this is in the wrong section, I really wasnt sure whether this belonged in this section or script requests, because I dont know whether it will require another script or what =p

This is SandGolem's multiple currencies script that I am using in my game:

#=============================================================================
# ** SG Multiple Currencies
#=============================================================================
# sandgolem    
# Version 3
# 18.06.06
#=============================================================================

# This requires event scripting to switch, see below.
# The only script-related things to edit is this:

$sg_currencies = { 'names' => ['Temp','W','R','D'], 
                   'icons' => ['','nec5','coin','jwl1'], 
                   'type' => [7,0,0,0],
                   'variables' => [7,2,3,4] }
                   
# These need to be ordered exactly the same. You can increase the amount of
# currencies by adding more to the end of each. 

# Temp is used for special occasions. See the tutorials section here for some
# odd ways of using it:   http://www.gamebaker.com/rmxp/tutorials/

# Set the G to what you have your gold name as in the database.

# Icons, type & vars are picked based on the order that you have your names set 
# to. Make sure you name the variables in RMXP so you won't reuse them.

# 'type' uses SG Window Control to set the window format.
# See the comments in that script for what options are available.

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

# To change the player's currency, use this in a call script:
#         sg_change_currency('NameHere')

# This changes your current currency and modifies the amount of gold you have
# to whatever it is set at. The amount of gold you had before is set to the
# variable listed for it. This can be used anywhere, even in other scripts

# The variable used for your current gold is NOT altered until you change the
# currency. To do checks for that amount ingame, just use the regular gold.

# Or, you can save it by using this in a script: sg_save_currency
# This command is included in sg_change_currency and generally not useful

#=============================================================================
#
# To check for updates or find more scripts, visit:
# http://www.gamebaker.com/rmxp/scripts/
#
# To use this script, copy it and insert it in a new section above "Main",
# under the default scripts and SDK (optional).
#
# Requires SG Settings Control & SG Window Control, found at above site

I sent an e-mail to SandGolem, but I have yet to recieve a response.

Here's what I want to do. I have two currencies in my world - Wampum and Rupees (which are defined by 'W' and 'R' near the top). I want to make it to where lets say 2 Wampum = 1 Rupee and you can do currency conversions between the two by talking to an NPC. Is this possible without another script? If it is, how do I do it?

I guess syvkal's currency script is exactly what you need. The link for that is in his signature, I think...

Sorry, I'll just reply here to save anyone else the trouble of figuring out how it works

All currencies are saved in variables, you could do that pretty easily with control variables & input number command.

If the player is currently using one of those currencies (if not, ignore this para): First use "sg_save_currency" in an event script before the trade talk. Then after the transaction is complete, use control variables to set a temp var to all their gold. Use change gold, and set it to remove all of your new variable. Then use change gold again and increase it by the current currency's variable.

I have an updated version of that script to automate the 2nd part but I'm not sure if I posted it yet. Test it before using, I may have forgotten how it works.

Note to self: Finish those tutorials when Emerald is done

Thanks man, I appreciate it

Umm if you still need mine then as Bluescope said it's in my Sig.
