VX Formula Library
Formulas are Ruby expressions that are evaluated at run-time. You can use them in damage formulas to determine how much damage you inflict with a skill, or you can use them in script calls to perform certain functions that aren't provided through the event interface by default.
A formula may contain special formula variables that you can use to craft your formulas.
The following formula variables are available:
- a - user of the action
- b - target of the action
- v - game variables (equivalent to $gameVariables)
