# Introduction

Ultimate Game Facts is a library of static functions to add facts globally and per actor which you can read/write anytime throught out entire game session. This eliminates the need of saving multitude of variables or getter/setter function for specific needs.

Think of this system as a database where you can track things that happens at gameplay. 

Imagine a scenario, where at Level 1 you defeated an enemy and picked up a key to a door. In Level 5, you need to unlock a door. Traditionally, you'll need to create a variable to read/write the key acquired state, save and load it later when required. But with Ultimate Game Facts, this is an example setup you can create.

### Determine Value Type

If you have a large amount of game facts and unsure about the value type associated with it, you can use this helper function to determine what type of value the given fact has.
