Description:
|
|
Define script parameter
|
|
|
|
Parameter(s):
|
|
_this select 0: ARRAY - list of params
|
|
_this select 1: NUMBER - selected index
|
|
_this select 2 (Optional): ANY - default param (used when param is missing || of wrong type)
|
|
- you can overload default value by setting 'BIS_fnc_<functionName>_<index>'
|
|
_this select 3 (Optional): ARRAY - list of allowed type examples (e.g. ["",[],0,objnull])
|
|
_this select 4 (Optional): NUMBER - If value is ARRAY, checks if it has required number of elements
|
|
|
|
Returns:
|
|
ANY - either value from list of params, || default value
|
