Introduction
This script allows you to ‘link’ a variable with some other element in your game, so when you refer to that variable to retrieve its value, it goes off and finds the value you REALLY want to retrieve. It is the equivalent of doing a Control Variables to set a variable, and then using the result in a calculation, a Show Text command, a description (via \v[x]), a Conditional Branch, etc., but removes the Control Variables step.

By adding a link for the variable, you never need to do a Control Variables to put a value in – it always does the calculation for you at the time you are referencing the variable (so it will always be completely up-to-date).

How to Use
Paste into a new script slot below Materials.
Edit the init_links method to add a new array element for each variable you what to link, along with a script command to eval whenever that variable is referenced.

Follow this format:

 
Examples:
Make \v[1] always show how many of item #8 you have in inventory:




Make \v[2] always show how many of weapon #3 you have in inventory (this would exclude equipped items, because of the way item_number works):
Make \v[3] always show how many opponents remain in your enemy’s troop:
Make \v[4] always show the player’s X position, and \v[5] always show the player’s Y position:
Make \v[6] always show the leader’s HP rate:

Known Issues
This is not reliable for using a linked variable as a condition on an event page, as the condition behind the link may change more often than event pages are polled to determine which one is active.

Author's Notes
I have added a check to ensure this still works with save files made prior to implementing this script.
If you add this script to a project that's half finished, you may go back and remove any commands that change the values in linked variables, but you do not have to - they will effectively be ignored.
Free to use in commercial games.
