Define script parameter


Parameter(s):
|p1= input: [[Array]] - list of params |= Parameter 1
_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 or 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:
|p2= index: [[Number]] - selected index |= Parameter 2
ANY - either value from list of params, or default value

Syntax

Syntax:
[input,index,(defaultValue,dataTypes,requiredCount)] call bis_fnc_param;
Parameters:
input: Array - list of params
index: Number - selected index
defaultValue (Optional): Anything - default param (used when param is missing or of wrong type). You can overload default value by setting 'BIS_fnc_<functionName>_<index>'
dataTypes (Optional): Array - list of allowed type examples (e.g. ["",[],0,objnull])
requiredCount (Optional): Number - If value is Array, checks if it has required number of elements
Return Value:
Anything

Examples

Example 1:
_target = [_this, 0, objNull, [objNull,[]], [2,3]] call bis_fnc_param;
  • If (_this select 0) is not defined, default objnull is used.
  • If (_this select 0) is defined, but is neither of type Object nor Array, error message is logged and default objNull is used.
  • If (_this select 0) and is Array, but it's count is neither 2 nor 3, error message is logged and default objNull is used.
Example 2:
_answer = [_this, 1, 42] call bis_fnc_param;
  • If (_this select 0) is not defined, default 42 is used.
  • No limit for data types or number of elements exists.
