	<brief_description>
		A generic array datatype.
	</brief_description>
	<description>
		A generic array that 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 is the second to last, etc.).
		[b]Example:[/b]
		[codeblocks]
		[gdscript]
		var array = ["One", 2, 3, "Four"]
		print(array[0]) # One.
		print(array[2]) # 3.
		print(array[-1]) # Four.
		array[2] = "Three"
		print(array[-2]) # Three.
		[/gdscript]
		[csharp]
		var array = new Godot.Collections.Array{"One", 2, 3, "Four"};
		GD.Print(array[0]); // One.
		GD.Print(array[2]); // 3.
		GD.Print(array[array.Count - 1]); // Four.
		array[2] = "Three";
		GD.Print(array[array.Count - 2]); // Three.
		[/csharp]
		[/codeblocks]
		Arrays can be concatenated using the [code]+[/code] operator:
		[codeblocks]
		[gdscript]
		var array1 = ["One", 2]
		var array2 = [3, "Four"]
		print(array1 + array2) # ["One", 2, 3, "Four"]
		[/gdscript]
		[csharp]
		// Array concatenation is not possible with C# arrays, but is with Godot.Collections.Array.
		var array1 = new Godot.Collections.Array{"One", 2};
		var array2 = new Godot.Collections.Array{3, "Four"};
		GD.Print(array1 + array2); // Prints [One, 2, 3, Four]
		[/csharp]
		[/codeblocks]
		[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 that can be modified independently of the original array, use [method duplicate].
		[b]Note:[/b] Erasing elements while iterating over arrays is [b]not[/b] supported and will result in unpredictable behavior.
		[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.

	<methods>
		<method name="all" qualifiers="const">
			<return type="bool" />
			<param index="0" name="method" type="Callable" />
			<description>
				Calls the provided [Callable] on each element in the array and returns [code]true[/code] if the [Callable] returns [code]true[/code] for [i]all[/i] elements in the array. If the [Callable] returns [code]false[/code] for one array element or more, this method returns [code]false[/code].
				The callable's method should take one [Variant] parameter (the current array element) and return a boolean value.
				[codeblock]
				func _ready():
				    print([6, 10, 6].all(greater_than_5))  # Prints True (3/3 elements evaluate to `true`).
				    print([4, 10, 4].all(greater_than_5))  # Prints False (1/3 elements evaluate to `true`).
				    print([4, 4, 4].all(greater_than_5))  # Prints False (0/3 elements evaluate to `true`).
				    print([].all(greater_than_5))  # Prints True (0/0 elements evaluate to `true`).

				    print([6, 10, 6].all(func(number): return number &gt; 5))  # Prints True. Same as the first line above, but using lambda function.

				func greater_than_5(number):
				    return number &gt; 5
				[/codeblock]
				See also [method any], [method filter], [method map] and [method reduce].
				[b]Note:[/b] Unlike relying on the size of an array returned by [method filter], this method will return as early as possible to improve performance (especially with large arrays).
				[b]Note:[/b] For an empty array, this method [url=https://en.wikipedia.org/wiki/Vacuous_truth]always[/url] returns [code]true[/code].
			</description>
		</method>
		<method name="any" qualifiers="const">
			<return type="bool" />
			<param index="0" name="method" type="Callable" />
			<description>
				Calls the provided [Callable] on each element in the array and returns [code]true[/code] if the [Callable] returns [code]true[/code] for [i]one or more[/i] elements in the array. If the [Callable] returns [code]false[/code] for all elements in the array, this method returns [code]false[/code].
				The callable's method should take one [Variant] parameter (the current array element) and return a boolean value.
				[codeblock]

				[b]Note:[/b] Unlike relying on the size of an array returned by [method filter], this method will return as early as possible to improve performance (especially with large arrays).
				[b]Note:[/b] For an empty array, this method always returns [code]false[/code].
			</description>
		</method>
		<method name="append">
			<return type="void" />
			<param index="0" name="value" type="Variant" />
			<description>
				Appends an element at the end of the array (alias of [method push_back]).
			</description>
		</method>
		<method name="append_array">
			<return type="void" />
			<param index="0" name="array" type="Array" />
			<description>
				Appends another array at the end of this array.
				[codeblock]
				var array1 = [1, 2, 3]
				var array2 = [4, 5, 6]
				array1.append_array(array2)
				print(array1) # Prints [1, 2, 3, 4, 5, 6].
				[/codeblock]
			</description>
		</method>
		<method name="back" qualifiers="const">
			<return type="Variant" />
			<description>
				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.
			</description>
		</method>
		<method name="bsearch">
			<return type="int" />
			<param index="0" name="value" type="Variant" />
			<param index="1" name="before" type="bool" default="true" />
			<description>
				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 [param before] 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.
			</description>
		</method>
		<method name="bsearch_custom">
			<return type="int" />
			<param index="0" name="value" type="Variant" />
			<param index="1" name="func" type="Callable" />
			<param index="2" name="before" type="bool" default="true" />
			<description>
				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 [param before] 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_custom] on an unsorted array results in unexpected behavior.
			</description>
		</method>
		<method name="clear">
			<return type="void" />
			<description>
				Clears the array. This is equivalent to using [method resize] with a size of [code]0[/code].
			</description>
		</method>
		<method name="count" qualifiers="const">
			<return type="int" />
			<param index="0" name="value" type="Variant" />
			<description>
				Returns the number of times an element is in the array.
			</description>
		</method>
		<method name="duplicate" qualifiers="const">
			<return type="Array" />
			<param index="0" name="deep" type="bool" default="false" />
			<description>
				Returns a copy of the array.
				If [param deep] 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. Note that any [Object]-derived elements will be shallow copied regardless of the [param deep] setting.
			</description>
		</method>
		<method name="erase">
			<return type="void" />
			<param index="0" name="value" type="Variant" />
			<description>
				Removes the first occurrence of a value from the array. If the value does not exist in the array, nothing happens. To remove an element by index, use [method remove_at] instead.
				[b]Note:[/b] This method acts in-place and doesn't return a value.
				[b]Note:[/b] On large arrays, this method will be slower if the removed element is close to the beginning of the array (index 0). This is because all elements placed after the removed element have to be reindexed.
				[b]Note:[/b] Do not erase entries while iterating over the array.
			</description>
		</method>
		<method name="fill">
			<return type="void" />
			<param index="0" name="value" type="Variant" />
			<description>
				Assigns the given value to all elements in the array. This can typically be used together with [method resize] to create an array with a given size and initialized elements:
				[codeblocks]
				[gdscript]
				var array = []
				array.resize(10)
				array.fill(0) # Initialize the 10 elements to 0.
				[/gdscript]
				[csharp]
				var array = new Godot.Collections.Array{};
				array.Resize(10);
				array.Fill(0); // Initialize the 10 elements to 0.
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] If [param value] is of a reference type ([Object]-derived, [Array], [Dictionary], etc.) then the array is filled with the references to the same object, i.e. no duplicates are created.

		<method name="filter" qualifiers="const">
			<return type="Array" />
			<param index="0" name="method" type="Callable" />
			<description>
				Calls the provided [Callable] on each element in the array and returns a new array with the elements for which the method returned [code]true[/code].
				The callable's method should take one [Variant] parameter (the current array element) and return a boolean value.
				[codeblock]
				func _ready():
				    print([1, 2, 3].filter(remove_1)) # Prints [2, 3].
				    print([1, 2, 3].filter(func(number): return number != 1)) # Same as above, but using lambda function.

				func remove_1(number):
				    return number != 1

		<method name="find" qualifiers="const">
			<return type="int" />
			<param index="0" name="what" type="Variant" />
			<param index="1" name="from" type="int" default="0" />
			<description>
				Searches the array for a value and returns its index or [code]-1[/code] if not found. Optionally, the initial search index can be passed.
			</description>
		</method>
		<method name="front" qualifiers="const">
			<return type="Variant" />
			<description>
				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.
			</description>
		</method>
		<method name="get_typed_builtin" qualifiers="const">
			<return type="int" />
			<description>
				Returns the [enum Variant.Type] constant for a typed array. If the [Array] is not typed, returns [constant TYPE_NIL].

			<description>
				Returns the script associated with a typed array tied to a class name.
			</description>
		</method>
		<method name="has" qualifiers="const">
			<return type="bool" />
			<param index="0" name="value" type="Variant" />
			<description>
				Returns [code]true[/code] if the array contains the given value.
				[codeblocks]
				[gdscript]
				print(["inside", 7].has("inside")) # True
				print(["inside", 7].has("outside")) # False
				print(["inside", 7].has(7)) # True

				GD.Print(arr.Contains(7)); // True
				GD.Print(arr.Contains("7")); // False
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] This is equivalent to using the [code]in[/code] operator as follows:
				[codeblocks]
				[gdscript]
				# Will evaluate to `true`.
				if 2 in [2, 4, 6, 8]:
				    print("Contains!")
				[/gdscript]
				[csharp]
				// As there is no "in" keyword in C#, you have to use Contains

				    GD.Print("Contains!");
				}
				[/csharp]
				[/codeblocks]
			</description>
		</method>
		<method name="hash" qualifiers="const">
			<return type="int" />
			<description>
				Returns a hashed 32-bit integer value representing the array and its contents.
				[b]Note:[/b] [Array]s with equal content will always produce identical hash values. However, the reverse is not true. Returning identical hash values does [i]not[/i] imply the arrays are equal, because different arrays can have identical hash values due to hash collisions.
			</description>
		</method>
		<method name="insert">
			<return type="int" />
			<param index="0" name="position" type="int" />
			<param index="1" name="value" type="Variant" />
			<description>
				Inserts a new element at a given position in the array. The position must be valid, or at the end of the array ([code]pos == size()[/code]).
				[b]Note:[/b] This method acts in-place and doesn't return a value.
				[b]Note:[/b] On large arrays, this method will be slower if the inserted element is close to the beginning of the array (index 0). This is because all elements placed after the newly inserted element have to be reindexed.
			</description>
		</method>
		<method name="is_empty" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the array is empty.
			</description>
		</method>
		<method name="is_read_only" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the array is read-only. See [method set_read_only]. Arrays are automatically read-only if declared with [code]const[/code] keyword.
			</description>
		</method>
		<method name="is_typed" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the array is typed. Typed arrays can only store elements of their associated type and provide type safety for the [code][][/code] operator. Methods of typed array still return [Variant].
			</description>
		</method>
		<method name="map" qualifiers="const">
			<return type="Array" />
			<param index="0" name="method" type="Callable" />
			<description>
				Calls the provided [Callable] for each element in the array and returns a new array filled with values returned by the method.
				The callable's method should take one [Variant] parameter (the current array element) and can return any [Variant].
				[codeblock]
				func _ready():
				    print([1, 2, 3].map(negate)) # Prints [-1, -2, -3].
				    print([1, 2, 3].map(func(number): return -number)) # Same as above, but using lambda function.

				func negate(number):
				    return -number

			</description>
		</method>
		<method name="max" qualifiers="const">
			<return type="Variant" />
			<description>
				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.
			</description>
		</method>
		<method name="min" qualifiers="const">
			<return type="Variant" />
			<description>
				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.
			</description>
		</method>
		<method name="pick_random" qualifiers="const">
			<return type="Variant" />
			<description>
				Returns a random value from the target array.
				[codeblock]
				var array: Array[int] = [1, 2, 3, 4]

				[/codeblock]
			</description>
		</method>
		<method name="pop_at">
			<return type="Variant" />
			<param index="0" name="position" type="int" />
			<description>
				Removes and returns the element of the array at index [param position]. If negative, [param position] is considered relative to the end of the array. Leaves the array untouched and returns [code]null[/code] if the array is empty or if it's accessed out of bounds. An error message is printed when the array is accessed out of bounds, but not when the array is empty.
				[b]Note:[/b] On large arrays, this method can be slower than [method pop_back] as it will reindex the array's elements that are located after the removed element. The larger the array and the lower the index of the removed element, the slower [method pop_at] will be.
			</description>
		</method>
		<method name="pop_back">
			<return type="Variant" />
			<description>
				Removes and returns the last element of the array. Returns [code]null[/code] if the array is empty, without printing an error message. See also [method pop_front].
			</description>
		</method>
		<method name="pop_front">
			<return type="Variant" />
			<description>
				Removes and returns the first element of the array. Returns [code]null[/code] if the array is empty, without printing an error message. See also [method pop_back].
				[b]Note:[/b] On large arrays, this method is much slower than [method pop_back] as it will reindex all the array's elements every time it's called. The larger the array, the slower [method pop_front] will be.
			</description>
		</method>
		<method name="push_back">
			<return type="void" />
			<param index="0" name="value" type="Variant" />
			<description>
				Appends an element at the end of the array. See also [method push_front].
			</description>
		</method>
		<method name="push_front">
			<return type="void" />
			<param index="0" name="value" type="Variant" />
			<description>
				Adds an element at the beginning of the array. See also [method push_back].
				[b]Note:[/b] On large arrays, this method is much slower than [method push_back] as it will reindex all the array's elements every time it's called. The larger the array, the slower [method push_front] will be.

		<method name="reduce" qualifiers="const">
			<return type="Variant" />
			<param index="0" name="method" type="Callable" />
			<param index="1" name="accum" type="Variant" default="null" />
			<description>
				Calls the provided [Callable] for each element in array and accumulates the result in [param accum].
				The callable's method takes two arguments: the current value of [param accum] and the current array element. If [param accum] is [code]null[/code] (default value), the iteration will start from the second element, with the first one used as initial value of [param accum].
				[codeblock]
				func _ready():
				    print([1, 2, 3].reduce(sum, 10)) # Prints 16.
				    print([1, 2, 3].reduce(func(accum, number): return accum + number, 10)) # Same as above, but using lambda function.

				func sum(accum, number):
				    return accum + number

			</description>
		</method>
		<method name="remove_at">
			<return type="void" />
			<param index="0" name="position" type="int" />
			<description>
				Removes an element from the array by index. If the index does not exist in the array, nothing happens. To remove an element by searching for its value, use [method erase] instead.
				[b]Note:[/b] This method acts in-place and doesn't return a value.
				[b]Note:[/b] On large arrays, this method will be slower if the removed element is close to the beginning of the array (index 0). This is because all elements placed after the removed element have to be reindexed.
			</description>
		</method>
		<method name="resize">
			<return type="int" />
			<param index="0" name="size" type="int" />
			<description>
				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].
			</description>
		</method>
		<method name="reverse">
			<return type="void" />
			<description>
				Reverses the order of the elements in the array.
			</description>
		</method>
		<method name="rfind" qualifiers="const">
			<return type="int" />
			<param index="0" name="what" type="Variant" />
			<param index="1" name="from" type="int" default="-1" />
			<description>
				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.
			</description>
		</method>
		<method name="set_read_only">
			<return type="void" />
			<param index="0" name="enable" type="bool" />
			<description>
				Makes the [Array] read-only, i.e. disabled modifying of the array's elements. Does not apply to nested content, e.g. content of nested arrays.
			</description>
		</method>
		<method name="set_typed">
			<return type="void" />
			<param index="0" name="type" type="int" />
			<param index="1" name="class_name" type="StringName" />
			<param index="2" name="script" type="Variant" />
			<description>
				Makes the [Array] typed. The [param type] should be one of the [enum Variant.Type] constants. [param class_name] is optional and can only be provided for [constant TYPE_OBJECT]. [param script] can only be provided if [param class_name] is not empty.
				The method fails if an array is already typed.
			</description>
		</method>
		<method name="shuffle">
			<return type="void" />
			<description>
				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 @GlobalScope.randi]. Call [method @GlobalScope.randomize] to ensure that a new seed will be used each time if you want non-reproducible shuffling.
			</description>
		</method>
		<method name="size" qualifiers="const">
			<return type="int" />
			<description>
				Returns the number of elements in the array.
			</description>
		</method>
		<method name="slice" qualifiers="const">
			<return type="Array" />
			<param index="0" name="begin" type="int" />
			<param index="1" name="end" type="int" default="2147483647" />
			<param index="2" name="step" type="int" default="1" />
			<param index="3" name="deep" type="bool" default="false" />
			<description>
				Returns the slice of the [Array], from [param begin] (inclusive) to [param end] (exclusive), as a new [Array].
				The absolute value of [param begin] and [param end] will be clamped to the array size, so the default value for [param end] makes it slice to the size of the array by default (i.e. [code]arr.slice(1)[/code] is a shorthand for [code]arr.slice(1, arr.size())[/code]).
				If either [param begin] or [param end] are negative, they will be relative to the end of the array (i.e. [code]arr.slice(0, -2)[/code] is a shorthand for [code]arr.slice(0, arr.size() - 2)[/code]).
				If specified, [param step] is the relative index between source elements. It can be negative, then [param begin] must be higher than [param end]. For example, [code][0, 1, 2, 3, 4, 5].slice(5, 1, -2)[/code] returns [code][5, 3][/code]).
				If [param deep] is true, each element will be copied by value rather than by reference.
			</description>
		</method>
		<method name="sort">
			<return type="void" />
			<description>
				Sorts the array.
				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that values considered equal may have their order changed when using [method sort].
				[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:
				[codeblocks]
				[gdscript]
				var strings = ["string1", "string2", "string10", "string11"]
				strings.sort()
				print(strings) # Prints [string1, string10, string11, string2]
				[/gdscript]
				[csharp]
				// There is no sort support for Godot.Collections.Array
				[/csharp]
				[/codeblocks]
				To perform natural order sorting, you can use [method sort_custom] with [method String.naturalnocasecmp_to] as follows:
				[codeblock]
				var strings = ["string1", "string2", "string10", "string11"]
				strings.sort_custom(func(a, b): return a.naturalnocasecmp_to(b) &lt; 0)
				print(strings) # Prints [string1, string2, string10, string11]
				[/codeblock]
			</description>
		</method>
		<method name="sort_custom">
			<return type="void" />
			<param index="0" name="func" type="Callable" />
			<description>
				Sorts the array using a custom 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]. For two elements [code]a[/code] and [code]b[/code], if the given method returns [code]true[/code], element [code]b[/code] will be after element [code]a[/code] in the array.
				[b]Note:[/b] The sorting algorithm used is not [url=https://en.wikipedia.org/wiki/Sorting_algorithm#Stability]stable[/url]. This means that values considered equal may have their order changed when using [method sort_custom].
				[b]Note:[/b] You cannot randomize the return value as the heapsort algorithm expects a deterministic result. Randomizing the return value will result in unexpected behavior.
				[codeblocks]
				[gdscript]
				func sort_ascending(a, b):
				    if a[0] &lt; b[0]:
				        return true
				    return false

				func _ready():
				    var my_items = [[5, "Potato"], [9, "Rice"], [4, "Tomato"]]
				    my_items.sort_custom(sort_ascending)
				    print(my_items) # Prints [[4, Tomato], [5, Potato], [9, Rice]].

				    # Descending, lambda version.
				    my_items.sort_custom(func(a, b): return a[0] &gt; b[0])
				    print(my_items) # Prints [[9, Rice], [5, Potato], [4, Tomato]].
