Description
- Description:
- Load a script parameter. See Functions Library (Arma 3) for detailed description.
- 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): 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): 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.

- (A3 1.28) Use BIS_fnc_paramIn to load private path from parent parameters (loaded by BIS_fnc_param)
private ["_parent","_child0","_child1"]; _parent = [_this,0,[],[[]]] call BIS_fnc_param; _child0 = [_parent,0,missionNamespace,[ missionNamespace,grpNull,objNull ]] call BIS_fnc_paramIn; _child1 = [_parent,1,"",[""]] call BIS_fnc_paramIn;
