Introduction

This script allows you to easily have multiple currencies with icons and quickly change from them. By default, it's set up with "G", "Tokens" and "Tickets" (Casino/Arcade?)

It uses these icons, which can be changed with one line:
(all three images lost)

Features

• Change currencies at any time
  
• No maximum amount of currencies
  
• Only three lines to edit in the entire script
  
• Shows currency with an icon in the gold window
  
• Stored as variables, which can be easily checked in events
  
• SDK compatable and also works without it - no commenting necessary
  

Script

Place it above main, under the SDK if you're using it

#=============================================================================
#
# Part of this script was based on one "Link_05" posted to rmxp.net boards
# An additional edit to it was by him, with the icon shown on the left
# (The "Icon where currency (Gold) is" script)
#
# If you don't intend to use multiple currencies in your game, I highly
# recommend using that script instead of this one to show it's icon!
#
#=============================================================================
#
# This requires event scripting to switch, see below.
#
# The only script-related things to edit is this:
#
$sg_currency_names = ['G','Token','Ticket']
$sg_currency_icons = ['mbag','coin','card']
$sg_currency_vars = [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.
#
# Set the first to what you have your gold name as in the database.
# Icons and vars are picked based on the order that you have your names set
# to. Make sure you name the variable in RMXP so you won't reuse it.
#
#=============================================================================
#
# 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
#

Instructions

Use this command in an event's call script (or any other script) to change the currency:

Code:

sg_change_currency('NameHere')

Your current currency saved in the variable is not changed until you run that command, use the regular gold options to check how much of it you have. You can also force it to save by using this (included in sg_change_currency): sg_save_currency

Change the three uncommented lines at the start of the script to whatever you'd like. One of the currencies must be named the same as your gold name in the database

Compatibility

This script rewrites Window_Gold's refresh, so place it above any others that use that.

Credits and Thanks

Part of this script was based on one Link_05 posted on .net titled "Icon where currency (Gold) is"

Prexus for the way to have it not crash if the SDK isn't present

Thanks to Magic Magor, MeisMe, Prexus & SephirothSpawn for putting up with newbie-ish scripting questions.

Author's Notes

Since they're stored as variables, you can easily check the others ingame for whatever reason without changing your gold. I have a "Currency Shop" add-on in the works that should be posted soon

Useful script? Any weird bugs or horrible coding? Let me know!

edit: Added sg_save_currency to the comments. Nothing new
