Description

Description:
Changes the element at the given zero-based index of the array.
ⓘ
If the index is out of bounds, the array will resize to incorporate the index as its last value, padding with nil as necessary (see Example 4).
Groups:
ArraysHashMap

Syntax

Syntax:
array set [index, value]
Parameters:
array: Array
index: Number - 0-based array index. Arma 3 logo black.png2.12 negative index can be used to select from the end of the array, i.e. -1 means last array element.
value: Anything
Return Value:
Nothing

Alternative Syntax

Syntax:
hashMap set [key, value, insertOnly]
Parameters:
hashMap: HashMap
key: HashMapKey
value: Anything
since Arma 3 logo black.png2.08
insertOnly: Boolean - (Optional, default false) if set to true, set the value only if the key does not exist already
Return Value:
Boolean - false if the key is new to the hashmap, true if a value got overwritten

Examples

Example 1:
_arrayOne set [0, "Hello"];
Example 2:
Append "Bye" as last element to _arrayTwo:
_arrayTwo set [count _arrayTwo, "Bye"];
Example 3:
Replace the last element of _arrayThree with 23:
_arrayThree set [(count _arrayThree) - 1, 23];
Example 4:
Using set with an index that is out of bounds:
private _array = ["A"]; _array set [2, "C"]; // _array is now ["A", nil, "C"] _array set [1, "B"]; // _array is now ["A", "B", "C"]
Example 5:
private _myHashMap = createHashMap; _myHashMap set ["key", "value1", true]; // "key" value is set to "value1" _myHashMap set ["key", "value2", true]; // "key" value is still "value1" as "key" already exists in the hashmap
