Description

Description:
Load a script parameter. See Arma 3: Functions Library for detailed description.
Arma 3
Use param or params commands instead.
Execution:
call
Groups:
Arrays

Syntax

Syntax:
[input, index, defaultValue, dataTypes, requiredCount] call BIS_fnc_param
Parameters:
input: Array - List of params
index: Number - Selected index
defaultValue (Optional, default Nothing): Anything - Default param (used when param is missing or of wrong type).
You can overload default value by declaring variable BIS_fnc_<functionName>_<index> in Namespace where BIS_fnc_param is called from.
BIS_fnc_paramIn is a variant of the function with overloading disabled.
dataTypes (Optional, default Anything): Array - List of allowed type examples (e.g. ["",[],0,objNull])
requiredCount (Optional): Number or Array - 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 is 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 1) is not defined, default 42 is used.
  • No limit for data types or number of elements exists.
