			<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 integer red, green, blue, and alpha channels. Each channel should have 8 bits of information ranging from 0 to 255.
				[code]r8[/code] red channel
				[code]g8[/code] green channel
				[code]b8[/code] blue channel
				[code]a8[/code] alpha channel
				[codeblock]

		<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 [code]condition[/code] is [code]true[/code]. If the [code]condition[/code] 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.
				[b]Note:[/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.
				The optional [code]message[/code] argument, if given, is shown in addition to the generic "Assertion failed" message. It must be a static string, so format strings can't be used. You can use this to provide additional details about why the assertion failed.
				[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 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]

		</method>
		<method name="convert">
			<return type="Variant" />
			<param index="0" name="what" type="Variant" />
			<param index="1" name="type" type="int" />
			<description>
				Converts from a type to another in the best way possible. The [code]type[/code] parameter uses the [enum Variant.Type] values.
				[codeblock]
				a = Vector2(1, 0)
				# Prints 1
				print(a.length())
				a = convert(a, TYPE_STRING)
				# Prints 6 as "(1, 0)" is 6 characters
				print(a.length())
				[/codeblock]
			</description>
		</method>
		<method name="dict_to_inst">
			<return type="Object" />
			<param index="0" name="dictionary" type="Dictionary" />
			<description>
				Converts a [param dictionary] (previously created with [method inst_to_dict]) back to an Object instance. 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]
				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] [method get_stack] 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] Not supported for calling from threads. Instead, this 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 (useful for serializing).
				[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="len">
			<return type="int" />
			<param index="0" name="var" type="Variant" />
			<description>
				Returns length of Variant [code]var[/code]. Length is the character count of String, element count of Array, size of Dictionary, etc.
				[b]Note:[/b] Generates a fatal error if Variant can not provide a length.
				[codeblock]
				a = [1, 2, 3, 4]
				len(a) # Returns 4
				[/codeblock]
			</description>
		</method>
		<method name="load">
			<return type="Resource" />
			<param index="0" name="path" type="String" />
			<description>
				Loads a resource from the filesystem located at [code]path[/code]. The resource is loaded on the method call (unless it's referenced already elsewhere, e.g. in another script or in the scene), which might cause slight delay, especially when loading 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 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 local path will just return [code]null[/code].
				This method is a simplified version of [method ResourceLoader.load], which can be used for more advanced scenarios.
				[b]Note:[/b] You have to import the files into the engine first to load them using [method load]. 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].
			</description>
		</method>
		<method name="preload">
			<return type="Resource" />
			<param index="0" name="path" type="String" />
			<description>
				Returns a [Resource] from the filesystem located at [code]path[/code]. The resource is loaded during script parsing, i.e. is loaded with the script and [method preload] effectively acts as a reference to that resource. Note that the method requires a constant path. 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 script.
				[codeblock]
				# Instance 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.
				Output in the console would look something like this:
				[codeblock]
				Test print
				   At: res://test.gd:15:_process()
				[/codeblock]
				[b]Note:[/b] Not supported for calling from threads. Instead of the stack frame, this will 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].
				Output in the console would look something like this:
				[codeblock]
				Frame 0 - res://test.gd:16 in function '_process'
				[/codeblock]
				[b]Note:[/b] [method print_stack] 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] Not supported for calling from threads. Instead of the stack trace, this will 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(), 0, -1):
				    print(array[i - 1])
				[/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="str" qualifiers="vararg">
			<return type="String" />
			<description>
				Converts one or more arguments to string in the best way possible.
				[codeblock]
				var a = [10, 20, 30]
				var b = str(a);
				len(a) # Returns 3
				len(b) # Returns 12
				[/codeblock]
			</description>
		</method>
		<method name="type_exists">
			<return type="bool" />
			<param index="0" name="type" type="StringName" />
			<description>
				Returns whether 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]Note:[/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 it is not equal to itself ([code]NAN == NAN[/code] returns [code]false[/code]). It is output by some invalid operations, such as dividing floating-point [code]0.0[/code] by [code]0.0[/code].
			[b]Note:[/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.

			<description>
				Export a numeric 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]"no_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].
				See also [constant PROPERTY_USAGE_SUBGROUP].
				[codeblock]
				@export_group("My Properties")
				@export var number = 3
				@export var string = ""

				@export_subgroup("My Prefixed Properties", "prefix_")
				@export var prefix_number = 3
				@export var prefix_string = ""
				[/codeblock]
				[b]Note:[/b] Subgroups cannot be nested, they only provide one extra level of depth. Just like the next group ends the previous group, so do the subsequent subgroups.
