This function returns a new array containing the values of the input array (or a range of it) with any duplicate values removed.
array_unique(array, [offset], [length]);
| Argument | Type | Description |
|---|---|---|
| array | Array | The array to use |
| offset | Real | OPTIONAL The offset, or the starting index, in the array. Setting a negative value will count from the end of the array. The starting index will then be array_length(array) + offset. See: Offset And Length |
| length | Real | OPTIONAL The number of elements to traverse. A negative value will traverse the array backwards (i.e. in descending order of indices, e.g. 2 > 1 > 0 instead of 0 > 1 > 2). See: Offset And Length |
var _values = ["rock", "paper", "scissors", "rock", "rock", "scissors", "paper", "scissors"];
var _values_unique = array_unique(_values);
The above code first creates a temporary array values.
It then calls array_unique and stores the result in a temporary variable values_unique. This array contains the three possible values in the array values: "rock", "paper" and "scissors".
