Description
- Description:
- Add two numbers, concatenate two arrays or two strings, or duplicate an array. For arrays also see pushBack and append.
- Groups:
- Math
Syntax 1
- Syntax:
- numberA + numberB
- Parameters:
- numberA: Number
- numberB: Number
- Return Value:
- Number - the sum of numberA and numberB
Syntax 2
Syntax 3
- Syntax:
- arrayA + arrayB
- Parameters:
- arrayA: Array
- arrayB: Array
- Return Value:
- Array - a new array filled with arrayA and arrayB elements, in that order.
Syntax 4
- Syntax:
- stringA + stringB
- Parameters:
- stringA: String
- stringB: String
- Return Value:
- String - a string concatenating stringA and stringB
Syntax 5
- Syntax:
- + arrayA
- Parameters:
- arrayA: Array
- Return Value:
- Array - a new instance of array filled with same items.
Examples
- Example 1:
5 + 3; // returns 8 -5 + -3; // returns -8- Example 2:
+ 2; // returns 2 + -7; // returns -7- Example 3:
_arrayA = [1,2,3]; _arrayB = [3,4,5]; _arrayAB = _arrayA + _arrayB; // _arrayAB = [1,2,3,3,4,5] // _arrayA and _arrayB remain unchanged- Example 4:
_result = "Hello" + " " + "there"; // "Hello there"- Example 5:
_arrayA = [1,2,3]; _arrayB = +_arrayA; _arrayB set [0, 99]; // _arrayA = [1,2,3], _arrayB = [99,2,3]- Example 6:
- Shallow copy with ARRAY + []:
private _subArray = [1, 2, 3]; private _array1 = [_subArray, 1, 2, 3]; private _array2 = _array1 + []; _array2 select 0 set [0, "oops"]; hint str _subArray; // ["oops", 2, 3]Deep copy with +ARRAY:private _subArray = [1, 2, 3]; private _array1 = [_subArray, 1, 2, 3]; private _array2 = +_array1; _array2 select 0 set [0, "oops"]; hint str _subArray; // [1, 2, 3]
