====== Hidden Input Variables ======

===== Syntax =====

$$VARNAME:VAL

===== Description =====

Hidden input variables must start with ''%%$$%%'' and be placed, together with other
[[4rpl:commands:define|input variables]], before 
any of the actual code in a script. 
They define a variable named **VARNAME **with a default value of **VAL** which may be of type int, float or string.

Unlike normal input variables, hidden input variables do not show up in a unit's Script Settings when selected 
in the editor, they are just a convenient way for defining some standard values at the start of a script.

Input variables are created at the same time as the unit itself (even if the game is paused and the script 
hasn't executed once) and assigned the default value **VAL**, which may be overwritten if the initParams 
of a [[4rpl:commands:CreateUnit |CreateUnit ]]call specify it.

===== Examples =====

<code 4rpl>
$$amt:1 
SetCreeper(10 10 <-amt) 
</code>
