Variable Conditional Events is a very popular add-on that allows users to create their own variables through a series of events that edit these variables.
Variables are statistics stored in bricks, players, clients, bots & vehicles. They are used to keep track of certain events so that other events know how to reacts. For example, two player variables, health & damage, are directly effected about each other. Damage is basically an inverse of health, if health is a 75, damage will be at 25. But variables are not limited to these.
There are several extensions for this add-on and can be very helpful during gameplay.
