 =====Frames to minutes===== =====Frames to minutes=====
 Converts an amount of frames to minutes in M:SS format. Frames stored in variable "frames"; result placed at top of stack. This is best used with Timers as it doesn't work when "frames" is 0. As in, it reaches 0:00 then just disappears. Converts an amount of frames to minutes in M:SS format. Frames stored in variable "frames"; result placed at top of stack.

 +=====GetClosestUnitToCoords=====
 +A customizable method to grab a nearest unit of any kind. Specify what types of units you want to grab, at what position, and with what radius. Strings are used for clarity to grab units that you need, you can delete or comment out units you wont be using once you copy the code. The code contains 3 methods that are commented for use on the battle-field. Contains two additional convenience methods.
 +<code>#Function :GetClosestUnitToCoords
 +#Warning: use this convenience function sparingly, tens of CRPL Cores
 +#running this all at once every frame can slow the game down.
 +
 +#Notation: x y f1 - i1
 +#eg. CurrentCoords 10 @GetClosestUnitToCoords ->unit
 +#If all units are outside of the maxDistance or none found returns integer value '-1'.
