All statistics (health, mana, accuracy, stamina.. etc etc) share the same traits. All have min, max, and default values, and you want to know when they hit certain thresholds. Unfortunately, there is no type that has all those features, there is only float, and for every statistic you end up writing the same code that adds those common traits. So for example you have float Health, and methods Set/Get health, that operate on it, make sure it stays in its bounds, if value reaches a threshold, you call event and so on. 

Over the years of working in game dev I got fed up writing this same code over and over again. Smart variable allows to:

  • Define min, max, and default values (and change them later, if for example player levelled up)
  • Bind event to OnMin/MaxReached, OnValueChanged, or to bind to any value threshold you set.
  • Query and/or display the history of operations made on it ; ) Either for debugging, or to show in-game combat log.
  • All features support replication
