Generic array which can contain several elements of any type, accessible by a numerical index starting at 0. Negative indices can be used to count from the back, like in Python (-1 is the last element, -2 the second to last, etc.).
[b]Note:[/b] Concatenating with the [code]+=[/code] operator will create a new array, which has a cost. If you want to append another array to an existing array, [method append_array] is more efficient.
[b]Note:[/b] Arrays are always passed by reference. To get a copy of an array which can be modified independently of the original array, use [method duplicate].
[b]Note:[/b] When declaring an array with [code]const[/code], the array itself can still be mutated by defining the values at individual indices or pushing/removing elements. Using [code]const[/code] will only prevent assigning the constant with another value after it was initialized.
Returns the last element of the array. Prints an error and returns [code]null[/code] if the array is empty.
[b]Note:[/b] Calling this function is not the same as writing [code]array[-1][/code]. If the array is empty, accessing by index will pause project execution when running from the editor.
Finds the index of an existing value (or the insertion index that maintains sorting order, if the value is not yet present in the array) using binary search. Optionally, a [code]before[/code] specifier can be passed. If [code]false[/code], the returned index comes after all existing entries of the value in the array.
[b]Note:[/b] Calling [method bsearch] on an unsorted array results in unexpected behavior.
Finds the index of an existing value (or the insertion index that maintains sorting order, if the value is not yet present in the array) using binary search and a custom comparison method. Optionally, a [code]before[/code] specifier can be passed. If [code]false[/code], the returned index comes after all existing entries of the value in the array. The custom method receives two arguments (an element from the array and the value searched for) and must return [code]true[/code] if the first argument is less than the second, and return [code]false[/code] otherwise.
[b]Note:[/b] Calling [method bsearch] on an unsorted array results in unexpected behavior.
If [code]deep[/code] is [code]true[/code], a deep copy is performed: all nested arrays and dictionaries are duplicated and will not be shared with the original array. If [code]false[/code], a shallow copy is made and references to the original nested arrays and dictionaries are kept, so that modifying a sub-array or dictionary in the copy will also impact those referenced in the source array.
Returns the first element of the array. Prints an error and returns [code]null[/code] if the array is empty.
[b]Note:[/b] Calling this function is not the same as writing [code]array[0][/code]. If the array is empty, accessing by index will pause project execution when running from the editor.
Returns the maximum value contained in the array if all elements are of comparable types. If the elements can't be compared, [code]null[/code] is returned.
Returns the minimum value contained in the array if all elements are of comparable types. If the elements can't be compared, [code]null[/code] is returned.
Resizes the array to contain a different number of elements. If the array size is smaller, elements are cleared, if bigger, new elements are [code]null[/code].
Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array.
Shuffles the array such that the items will have a random order. This method uses the global random number generator common to methods such as [method @GDScript.randi]. Call [method @GDScript.randomize] to ensure that a new seed will be used each time if you want non-reproducible shuffling.
Duplicates the subset described in the function and returns it in an array, deeply copying the array if [code]deep[/code] is [code]true[/code]. Lower and upper index are inclusive, with the [code]step[/code] describing the change between indices while slicing.
[b]Note:[/b] Strings are sorted in alphabetical order (as opposed to natural order). This may lead to unexpected behavior when sorting an array of strings ending with a sequence of numbers. Consider the following example:
[codeblock]
var strings = ["string1", "string2", "string10", "string11"]
strings.sort()
print(strings) # Prints [string1, string10, string11, string2]
Sorts the array using a custom method. The arguments are an object that holds the method and the name of such method. The custom method receives two arguments (a pair of elements from the array) and must return either [code]true[/code] or [code]false[/code].
[b]Note:[/b] you cannot randomize the return value as the heapsort algorithm expects a deterministic result. Doing so will result in unexpected behavior.
