	<methods>
		<method name="Color8">
			<return type="Color" />
			<param index="0" name="r8" type="int" />
			<param index="1" name="g8" type="int" />
			<param index="2" name="b8" type="int" />
			<param index="3" name="a8" type="int" default="255" />
			<description>
				Returns a [Color] constructed from red ([param r8]), green ([param g8]), blue ([param b8]), and optionally alpha ([param a8]) integer channels, each divided by [code]255.0[/code] for their final value. Using [method Color8] instead of the standard [Color] constructor is useful when you need to match exact color values in an [Image].
				[codeblock]
				var red = Color8(255, 0, 0)             # Same as Color(1, 0, 0).
				var dark_blue = Color8(0, 0, 51)        # Same as Color(0, 0, 0.2).
				var my_color = Color8(306, 255, 0, 102) # Same as Color(1.2, 1, 0, 0.4).
				[/codeblock]
				[b]Note:[/b] Due to the lower precision of [method Color8] compared to the standard [Color] constructor, a color created with [method Color8] will generally not be equal to the same color created with the standard [Color] constructor. Use [method Color.is_equal_approx] for comparisons to avoid issues with floating-point precision error.

		</method>
		<method name="assert">
			<return type="void" />
			<param index="0" name="condition" type="bool" />
			<param index="1" name="message" type="String" default="&quot;&quot;" />
			<description>
				Asserts that the [param condition] is [code]true[/code]. If the [param condition] is [code]false[/code], an error is generated. When running from the editor, the running project will also be paused until you resume it. This can be used as a stronger form of [method @GlobalScope.push_error] for reporting errors to project developers or add-on users.
				An optional [param message] can be shown in addition to the generic "Assertion failed" message. You can use this to provide additional details about why the assertion failed.
				[b]Warning:[/b] For performance reasons, the code inside [method assert] is only executed in debug builds or when running the project from the editor. Don't include code that has side effects in an [method assert] call. Otherwise, the project will behave differently when exported in release mode.
				[codeblock]
				# Imagine we always want speed to be between 0 and 20.
				var speed = -10
				assert(speed &lt; 20) # True, the program will continue.
				assert(speed &gt;= 0) # False, the program will stop.
				assert(speed &gt;= 0 and speed &lt; 20) # You can also combine the two conditional statements in one check.
				assert(speed &lt; 20, "the speed limit is 20") # Show a message.
				[/codeblock]
			</description>
		</method>
		<method name="char">
			<return type="String" />
			<param index="0" name="char" type="int" />
			<description>
				Returns a single character (as a [String]) of the given Unicode code point (which is compatible with ASCII code).
				[codeblock]
				a = char(65)      # a is "A"
				a = char(65 + 32) # a is "a"
				a = char(8364)    # a is "€"
				[/codeblock]
			</description>
		</method>
		<method name="convert">
			<return type="Variant" />
			<param index="0" name="what" type="Variant" />
			<param index="1" name="type" type="int" />
			<description>
				Converts [param what] to [param type] in the best way possible. The [param type] uses the [enum Variant.Type] values.
				[codeblock]
				var a = [4, 2.5, 1.2]
				print(a is Array) # Prints true

				var b = convert(a, TYPE_PACKED_BYTE_ARRAY)
				print(b)          # Prints [4, 2, 1]
				print(b is Array) # Prints false
				[/codeblock]
			</description>
		</method>
		<method name="dict_to_inst">
			<return type="Object" />
			<param index="0" name="dictionary" type="Dictionary" />
			<description>
				Converts a [param dictionary] (created with [method inst_to_dict]) back to an Object instance. Can be useful for deserializing.
			</description>
		</method>
		<method name="get_stack">
			<return type="Array" />
			<description>
				Returns an array of dictionaries representing the current call stack. See also [method print_stack].
				[codeblock]
				func _ready():
				    foo()

				func foo():
				    bar()

				func bar():
				    print(get_stack())
				[/codeblock]
				Starting from [code]_ready()[/code], [code]bar()[/code] would print:
				[codeblock]
				[{function:bar, line:12, source:res://script.gd}, {function:foo, line:9, source:res://script.gd}, {function:_ready, line:6, source:res://script.gd}]
				[/codeblock]
				[b]Note:[/b] This function only works if the running instance is connected to a debugging server (i.e. an editor instance). [method get_stack] will not work in projects exported in release mode, or in projects exported in debug mode if not connected to a debugging server.
				[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will return an empty array.
			</description>
		</method>
		<method name="inst_to_dict">
			<return type="Dictionary" />
			<param index="0" name="instance" type="Object" />
			<description>
				Returns the passed [param instance] converted to a Dictionary. Can be useful for serializing.
				[b]Note:[/b] Cannot be used to serialize objects with built-in scripts attached or objects allocated within built-in scripts.
				[codeblock]
				var foo = "bar"
				func _ready():
				    var d = inst_to_dict(self)
				    print(d.keys())
				    print(d.values())
				[/codeblock]
				Prints out:
				[codeblock]
				[@subpath, @path, foo]
				[, res://test.gd, bar]
				[/codeblock]
			</description>
		</method>
		<method name="is_instance_of">
			<return type="bool" />
			<param index="0" name="value" type="Variant" />
			<param index="1" name="type" type="Variant" />
			<description>
				Returns [code]true[/code] if [param value] is an instance of [param type]. The [param type] value must be one of the following:
				- A constant from the [enum Variant.Type] enumeration, for example [constant TYPE_INT].
				- An [Object]-derived class which exists in [ClassDB], for example [Node].
				- A [Script] (you can use any class, including inner one).
				Unlike the right operand of the [code]is[/code] operator, [param type] can be a non-constant value. The [code]is[/code] operator supports more features (such as typed arrays) and is more performant. Use the operator instead of this method if you do not need dynamic type checking.
				Examples:
				[codeblock]
				print(is_instance_of(a, TYPE_INT))
				print(is_instance_of(a, Node))
				print(is_instance_of(a, MyClass))
				print(is_instance_of(a, MyClass.InnerClass))
				[/codeblock]
				[b]Note:[/b] If [param value] and/or [param type] are freed objects (see [method @GlobalScope.is_instance_valid]), or [param type] is not one of the above options, this method will raise a runtime error.
				See also [method @GlobalScope.typeof], [method type_exists], [method Array.is_same_typed] (and other [Array] methods).
			</description>
		</method>
		<method name="len">
			<return type="int" />
			<param index="0" name="var" type="Variant" />
			<description>
				Returns the length of the given Variant [param var]. The length can be the character count of a [String], the element count of any array type or the size of a [Dictionary]. For every other Variant type, a run-time error is generated and execution is stopped.
				[codeblock]
				a = [1, 2, 3, 4]
				len(a) # Returns 4

				b = "Hello!"
				len(b) # Returns 6
				[/codeblock]
			</description>
		</method>
		<method name="load">
			<return type="Resource" />
			<param index="0" name="path" type="String" />
			<description>
				Returns a [Resource] from the filesystem located at the absolute [param path]. Unless it's already referenced elsewhere (such as in another script or in the scene), the resource is loaded from disk on function call, which might cause a slight delay, especially when loading large scenes. To avoid unnecessary delays when loading something multiple times, either store the resource in a variable or use [method preload].
				[b]Note:[/b] Resource paths can be obtained by right-clicking on a resource in the FileSystem dock and choosing "Copy Path", or by dragging the file from the FileSystem dock into the current script.
				[codeblock]
				# Load a scene called "main" located in the root of the project directory and cache it in a variable.
				var main = load("res://main.tscn") # main will contain a PackedScene resource.
				[/codeblock]
				[b]Important:[/b] The path must be absolute. A relative path will always return [code]null[/code].
				This function is a simplified version of [method ResourceLoader.load], which can be used for more advanced scenarios.
				[b]Note:[/b] Files have to be imported into the engine first to load them using this function. If you want to load [Image]s at run-time, you may use [method Image.load]. If you want to import audio files, you can use the snippet described in [member AudioStreamMP3.data].
				[b]Note:[/b] If [member ProjectSettings.editor/export/convert_text_resources_to_binary] is [code]true[/code], [method @GDScript.load] will not be able to read converted files in an exported project. If you rely on run-time loading of files present within the PCK, set [member ProjectSettings.editor/export/convert_text_resources_to_binary] to [code]false[/code].
			</description>
		</method>
		<method name="preload">
			<return type="Resource" />
			<param index="0" name="path" type="String" />
			<description>
				Returns a [Resource] from the filesystem located at [param path]. During run-time, the resource is loaded when the script is being parsed. This function effectively acts as a reference to that resource. Note that this function requires [param path] to be a constant [String]. If you want to load a resource from a dynamic/variable path, use [method load].
				[b]Note:[/b] Resource paths can be obtained by right-clicking on a resource in the Assets Panel and choosing "Copy Path", or by dragging the file from the FileSystem dock into the current script.
				[codeblock]
				# Create instance of a scene.
				var diamond = preload("res://diamond.tscn").instantiate()
				[/codeblock]
			</description>
		</method>
		<method name="print_debug" qualifiers="vararg">
			<return type="void" />
			<description>
				Like [method @GlobalScope.print], but includes the current stack frame when running with the debugger turned on.
				The output in the console may look like the following:
				[codeblock]
				Test print
				At: res://test.gd:15:_process()
				[/codeblock]
				[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will instead print the thread ID.
			</description>
		</method>
		<method name="print_stack">
			<return type="void" />
			<description>
				Prints a stack trace at the current code location. See also [method get_stack].
				The output in the console may look like the following:
				[codeblock]
				Frame 0 - res://test.gd:16 in function '_process'
				[/codeblock]
				[b]Note:[/b] This function only works if the running instance is connected to a debugging server (i.e. an editor instance). [method print_stack] will not work in projects exported in release mode, or in projects exported in debug mode if not connected to a debugging server.
				[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will instead print the thread ID.
			</description>
		</method>
		<method name="range" qualifiers="vararg">
			<return type="Array" />
			<description>
				Returns an array with the given range. [method range] can be called in three ways:
				[code]range(n: int)[/code]: Starts from 0, increases by steps of 1, and stops [i]before[/i] [code]n[/code]. The argument [code]n[/code] is [b]exclusive[/b].
				[code]range(b: int, n: int)[/code]: Starts from [code]b[/code], increases by steps of 1, and stops [i]before[/i] [code]n[/code]. The arguments [code]b[/code] and [code]n[/code] are [b]inclusive[/b] and [b]exclusive[/b], respectively.
				[code]range(b: int, n: int, s: int)[/code]: Starts from [code]b[/code], increases/decreases by steps of [code]s[/code], and stops [i]before[/i] [code]n[/code]. The arguments [code]b[/code] and [code]n[/code] are [b]inclusive[/b] and [b]exclusive[/b], respectively. The argument [code]s[/code] [b]can[/b] be negative, but not [code]0[/code]. If [code]s[/code] is [code]0[/code], an error message is printed.
				[method range] converts all arguments to [int] before processing.
				[b]Note:[/b] Returns an empty array if no value meets the value constraint (e.g. [code]range(2, 5, -1)[/code] or [code]range(5, 5, 1)[/code]).
				Examples:
				[codeblock]
				print(range(4))        # Prints [0, 1, 2, 3]
				print(range(2, 5))     # Prints [2, 3, 4]
				print(range(0, 6, 2))  # Prints [0, 2, 4]
				print(range(4, 1, -1)) # Prints [4, 3, 2]
				[/codeblock]
				To iterate over an [Array] backwards, use:
				[codeblock]
				var array = [3, 6, 9]
				for i in range(array.size() - 1, -1, -1):
				    print(array[i])
				[/codeblock]
				Output:
				[codeblock]
				9
				6
				3
				[/codeblock]
				To iterate over [float], convert them in the loop.
				[codeblock]
				for i in range (3, 0, -1):
				    print(i / 10.0)
				[/codeblock]
				Output:
				[codeblock]
				0.3
				0.2
				0.1
				[/codeblock]
			</description>
		</method>
		<method name="type_exists">
			<return type="bool" />
			<param index="0" name="type" type="StringName" />
			<description>
				Returns [code]true[/code] if the given [Object]-derived class exists in [ClassDB]. Note that [Variant] data types are not registered in [ClassDB].
				[codeblock]
				type_exists("Sprite2D") # Returns true
				type_exists("NonExistentClass") # Returns false
				[/codeblock]

	<constants>
		<constant name="PI" value="3.14159265358979">
			Constant that represents how many times the diameter of a circle fits around its perimeter. This is equivalent to [code]TAU / 2[/code], or 180 degrees in rotations.
		</constant>
		<constant name="TAU" value="6.28318530717959">
			The circle constant, the circumference of the unit circle in radians. This is equivalent to [code]PI * 2[/code], or 360 degrees in rotations.
		</constant>
		<constant name="INF" value="inf">
			Positive floating-point infinity. This is the result of floating-point division when the divisor is [code]0.0[/code]. For negative infinity, use [code]-INF[/code]. Dividing by [code]-0.0[/code] will result in negative infinity if the numerator is positive, so dividing by [code]0.0[/code] is not the same as dividing by [code]-0.0[/code] (despite [code]0.0 == -0.0[/code] returning [code]true[/code]).
			[b]Warning:[/b] Numeric infinity is only a concept with floating-point numbers, and has no equivalent for integers. Dividing an integer number by [code]0[/code] will not result in [constant INF] and will result in a run-time error instead.
		</constant>
		<constant name="NAN" value="nan">
			"Not a Number", an invalid floating-point value. [constant NAN] has special properties, including that [code]!=[/code] always returns [code]true[/code], while other comparison operators always return [code]false[/code]. This is true even when comparing with itself ([code]NAN == NAN[/code] returns [code]false[/code] and [code]NAN != NAN[/code] returns [code]true[/code]). It is returned by some invalid operations, such as dividing floating-point [code]0.0[/code] by [code]0.0[/code].
			[b]Warning:[/b] "Not a Number" is only a concept with floating-point numbers, and has no equivalent for integers. Dividing an integer [code]0[/code] by [code]0[/code] will not result in [constant NAN] and will result in a run-time error instead.

	<annotations>
		<annotation name="@export">
			<return type="void" />
			<description>
				Mark the following property as exported (editable in the Inspector dock and saved to disk). To control the type of the exported property, use the type hint notation.
				[codeblock]
				@export var string = ""
				@export var int_number = 5
				@export var float_number: float = 5

				See also [constant PROPERTY_USAGE_CATEGORY].
				[codeblock]
				@export_category("Statistics")
				@export var hp = 30
				@export var speed = 1.25
				[/codeblock]
				[b]Note:[/b] Categories in the Inspector dock's list usually divide properties coming from different classes (Node, Node2D, Sprite, etc.). For better clarity, it's recommended to use [annotation @export_group] and [annotation @export_subgroup], instead.

		<annotation name="@export_enum" qualifiers="vararg">
			<return type="void" />
			<param index="0" name="names" type="String" />
			<description>
				Export an [int] or [String] property as an enumerated list of options. If the property is an [int], then the index of the value is stored, in the same order the values are provided. You can add explicit values using a colon. If the property is a [String], then the value is stored.
				See also [constant PROPERTY_HINT_ENUM].
				[codeblock]

				@export_enum("Slow:30", "Average:60", "Very Fast:200") var character_speed: int
				@export_enum("Rebecca", "Mary", "Leah") var character_name: String
				[/codeblock]
				If you want to set an initial value, you must specify it explicitly:
				[codeblock]
				@export_enum("Rebecca", "Mary", "Leah") var character_name: String = "Rebecca"
				[/codeblock]
				If you want to use named GDScript enums, then use [annotation @export] instead:

			<description>
				Export a floating-point property with an easing editor widget. Additional hints can be provided to adjust the behavior of the widget. [code]"attenuation"[/code] flips the curve, which makes it more intuitive for editing attenuation properties. [code]"positive_only"[/code] limits values to only be greater than or equal to zero.

				You can also combine several flags:
				[codeblock]
				@export_flags("Self:4", "Allies:8", "Self and Allies:12", "Foes:16")
				var spell_targets = 0
				[/codeblock]
				[b]Note:[/b] A flag value must be at least [code]1[/code] and at most [code]2 ** 32 - 1[/code].
				[b]Note:[/b] Unlike [annotation @export_enum], the previous explicit value is not taken into account. In the following example, A is 16, B is 2, C is 4.

			<description>
				Define a new group for the following exported properties. This helps to organize properties in the Inspector dock. Groups can be added with an optional [param prefix], which would make group to only consider properties that have this prefix. The grouping will break on the first property that doesn't have a prefix. The prefix is also removed from the property's name in the Inspector dock.
				If no [param prefix] is provided, then every following property will be added to the group. The group ends when then next group or category is defined. You can also force end a group by using this annotation with empty strings for parameters, [code]@export_group("", "")[/code].
				Groups cannot be nested, use [annotation @export_subgroup] to add subgroups within groups.

			<description>
				Export an [int] or [float] property as a range value. The range must be defined by [param min] and [param max], as well as an optional [param step] and a variety of extra hints. The [param step] defaults to [code]1[/code] for integer properties. For floating-point numbers this value depends on your [code]EditorSettings.interface/inspector/default_float_step[/code] setting.
				If hints [code]"or_greater"[/code] and [code]"or_less"[/code] are provided, the editor widget will not cap the value at range boundaries. The [code]"exp"[/code] hint will make the edited values on range to change exponentially. The [code]"hide_slider"[/code] hint will hide the slider element of the editor widget.
				Hints also allow to indicate the units for the edited value. Using [code]"radians"[/code] you can specify that the actual value is in radians, but should be displayed in degrees in the Inspector dock. [code]"degrees"[/code] allows to add a degree sign as a unit suffix. Finally, a custom suffix can be provided using [code]"suffix:unit"[/code], where "unit" can be any string.
				See also [constant PROPERTY_HINT_RANGE].

				Define a new subgroup for the following exported properties. This helps to organize properties in the Inspector dock. Subgroups work exactly like groups, except they need a parent group to exist. See [annotation @export_group].
