======Array======
----
An **array** is a scripting data type consisting of a collection or list of values. You can iterate through the values in an array using a "For" loop, or check if an array contains a certain value using the "contains" operator in a [[conditional expression]].
====Examples:====
array["ITEM_0001", "ITEM_0005", "ITEM_0008"]
User-defined list of [[item]] IDs (e.g. from which to randomly pick an item for the player).
group["room_01"]
List of all entities in the current [[map]] that belong to the [[groups|group]] named "room_01". The values in this kind of array are of data type [[Entity]].
entity["xyz"].groups
List of all [[groups|group]] names to which the entity belongs, as assigned in the [[Map Editor]]. The values in this kind of array are of data type [[String]].
entity["xyz"].tags
List of all tags for the entity's model, as assigned in the [[Voxel Editor]]. The values in this kind of array are of data type [[String]].
range(5)
List of integers from 0 to, but not including, 5 (i.e. 0, 1, 2, 3, 4).
range(12, 15)
List of integers from 12 to, but not including, 15 (i.e. 12, 13, 14).
range(0, 9, 2)
List of integers from 0 to, but not including, 9, with an increment of 2 (i.e. 0, 2, 4, 6, 8).
range(5, 0, -1)
List of integers from 5 to, but not including, 0, with an increment of -1 (i.e. 5, 4, 3, 2, 1).
=====Functions=====
The following functions can be used to manipulate or retrieve the values in an array.
^Name^Description^
|push_front(value)|Appends a value to the beginning of an array.|
|push_back(value)|Appends a value to the end of an array.|
|pop_front()|Removes and returns the first value of an array.|
|pop_back()|Removes and returns the last value of an array.|
|insert(index, value)|Inserts a value into an array at the specified index (starting at 0).|
|remove(index)|Removes a value from an array at the specified index (starting at 0).|
|erase(value)|Removes the first occurrence of the specified value from an array.|
|clear()|Removes all values from an array.|
|size()|Returns the number of items in an array.|
====Examples:====
$my_array.push_front($my_value);
$my_array.push_back($my_value);
$first_value = $my_array.pop_front();
$last_value = $my_array.pop_back();
$my_array.insert(1, $my_value);
$my_array.remove(2);
$my_array.erase($my_value);
$my_array.clear();
$item_count = $my_array.size();
