====== Function Declaration ======

===== Syntax =====

:FunctionName

===== Description =====

Defines the beginning of a function block. Choose a unique name for the function. Statements after a function block only execute if called by invoking the  function with an '@FunctionName' call. The end of a function block is either the end of the script or the  beginning of another function, whichever comes first.

A few specific names exist that when used will make that function get automatically called by the game itself under certain circumstances. Read more about it under "Built in Function Callbacks" on the [[4rpl:start|Index]] page.

===== Examples =====

<code 4rpl>
# --- Roll a 100 sided die-------------- 
# --- Return true or false randomly. 
# --- The value on the stack is the percentage chance. 
# --- [ Chance_in_100 -- true/false] 
:chance 
	# Take an item from the stack, divide by 100, 
	# then compare to a random float. 
	100.0 div RandFloat gt
