		<method name="Color8">
			<return type="Color" />
			<argument index="0" name="r8" type="int" />
			<argument index="1" name="g8" type="int" />
			<argument index="2" name="b8" type="int" />
			<argument index="3" name="a8" type="int" default="255" />

		<method name="assert">
			<return type="void" />
			<argument index="0" name="condition" type="bool" />
			<argument 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 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. 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, "speed = %f, but the speed limit is 20" % speed) # Show a message with clarifying details
				[/codeblock]

				[codeblock]
				a = atan(0.5) # a is 0.463648
				[/codeblock]
			</description>
		</method>
		<method name="atan2">
			<return type="float" />
			<argument index="0" name="y" type="float" />
			<argument index="1" name="x" type="float" />
			<description>
				Returns the arc tangent of [code]y/x[/code] in radians. Use to get the angle of tangent [code]y/x[/code]. To compute the value, the method takes into account the sign of both arguments in order to determine the quadrant.
				Important note: The Y coordinate comes first, by convention.
				[codeblock]
				a = atan2(0, -1) # a is 3.141593
				[/codeblock]

		</method>
		<method name="ceil">
			<return type="float" />
			<argument index="0" name="s" type="float" />
			<description>
				Rounds [code]s[/code] upward (towards positive infinity), returning the smallest whole number that is not less than [code]s[/code].

		<method name="dectime">
			<return type="float" />
			<argument index="0" name="value" type="float" />
			<argument index="1" name="amount" type="float" />
			<argument index="2" name="step" type="float" />
			<description>
				[b]Note:[/b] [code]dectime[/code] has been deprecated and will be removed in Godot 4.0, please use [method move_toward] instead.
				Returns the result of [code]value[/code] decreased by [code]step[/code] * [code]amount[/code].
				[codeblock]
				a = dectime(60, 10, 0.1)) # a is 59.0

		</method>
		<method name="deep_equal">
			<return type="bool" />
			<argument index="0" name="a" type="Variant" />
			<argument index="1" name="b" type="Variant" />
			<description>
				Compares two values by checking their actual contents, recursing into any `Array` or `Dictionary` up to its deepest level.
				This compares to [code]==[/code] in a number of ways:
				- For [code]null[/code], [code]int[/code], [code]float[/code], [code]String[/code], [code]Object[/code] and [code]RID[/code] both [code]deep_equal[/code] and [code]==[/code] work the same.
				- For [code]Dictionary[/code], [code]==[/code] considers equality if, and only if, both variables point to the very same [code]Dictionary[/code], with no recursion or awareness of the contents at all.
				- For [code]Array[/code], [code]==[/code] considers equality if, and only if, each item in the first [code]Array[/code] is equal to its counterpart in the second [code]Array[/code], as told by [code]==[/code] itself. That implies that [code]==[/code] recurses into [code]Array[/code], but not into [code]Dictionary[/code].
				In short, whenever a [code]Dictionary[/code] is potentially involved, if you want a true content-aware comparison, you have to use [code]deep_equal[/code].
			</description>

		</method>
		<method name="ease">
			<return type="float" />
			<argument index="0" name="s" type="float" />
			<argument index="1" name="curve" type="float" />
			<description>
				Returns an "eased" value of [code]x[/code] based on an easing function defined with [code]curve[/code]. This easing function is based on an exponent. The [code]curve[/code] can be any floating-point number, with specific values leading to the following behaviors:
				[codeblock]
				- Lower than -1.0 (exclusive): Ease in-out
				- 1.0: Linear
				- Between -1.0 and 0.0 (exclusive): Ease out-in
				- 0.0: Constant
				- Between 0.0 to 1.0 (exclusive): Ease out
				- 1.0: Linear
				- Greater than 1.0 (exclusive): Ease in
				[/codeblock]
				[url=https://raw.githubusercontent.com/godotengine/godot-docs/3.4/img/ease_cheatsheet.png]ease() curve values cheatsheet[/url]

			</description>
		</method>
		<method name="exp">
			<return type="float" />
			<argument index="0" name="s" type="float" />
			<description>
				The natural exponential function. It raises the mathematical constant [b]e[/b] to the power of [code]s[/code] and returns it.
				[b]e[/b] has an approximate value of 2.71828, and can be obtained with [code]exp(1)[/code].
				For exponents to other bases use the method [method pow].
				[codeblock]

		</method>
		<method name="floor">
			<return type="float" />
			<argument index="0" name="s" type="float" />
			<description>

				[codeblock]
				a = floor(2.45)  # a is 2.0
				a = floor(2.99)  # a is 2.0
				a = floor(-2.99) # a is -3.0
				[/codeblock]
				See also [method ceil], [method round], [method stepify], and [int].
				[b]Note:[/b] This method returns a float. If you need an integer and [code]s[/code] is a non-negative number, you can use [code]int(s)[/code] directly.
			</description>
		</method>
		<method name="fmod">
			<return type="float" />
			<argument index="0" name="a" type="float" />
			<argument index="1" name="b" type="float" />
			<description>
				Returns the floating-point remainder of [code]a/b[/code], keeping the sign of [code]a[/code].

				-1.0 -1.0  0.5
				-0.5 -0.5  1.0
				 0.0  0.0  0.0

		<method name="funcref">
			<return type="FuncRef" />
			<argument index="0" name="instance" type="Object" />
			<argument index="1" name="funcname" type="String" />
			<description>
				Returns a reference to the specified function [code]funcname[/code] in the [code]instance[/code] node. As functions aren't first-class objects in GDscript, use [code]funcref[/code] to store a [FuncRef] in a variable and call it later.
				[codeblock]
				func foo():
				    return("bar")

				a = funcref(self, "foo")
				print(a.call_func()) # Prints bar

			<return type="Dictionary" />
			<argument index="0" name="inst" type="Object" />
			<description>
				Returns the passed instance converted to a dictionary (useful for serializing).
				[codeblock]
				var foo = "bar"
				func _ready():
				    var d = inst2dict(self)
				    print(d.keys())
				    print(d.values())

			<argument index="2" name="weight" type="float" />
			<description>
				Returns an interpolation or extrapolation factor considering the range specified in [code]from[/code] and [code]to[/code], and the interpolated value specified in [code]weight[/code]. The returned value will be between [code]0.0[/code] and [code]1.0[/code] if [code]weight[/code] is between [code]from[/code] and [code]to[/code] (inclusive). If [code]weight[/code] is located outside this range, then an extrapolation factor will be returned (return value lower than [code]0.0[/code] or greater than [code]1.0[/code]).
				[codeblock]
				# The interpolation ratio in the `lerp()` call below is 0.75.
				var middle = lerp(20, 30, 0.75)
				# `middle` is now 27.5.
				# Now, we pretend to have forgotten the original ratio and want to get it back.
				var ratio = inverse_lerp(20, 30, 27.5)
				# `ratio` is now 0.75.
				[/codeblock]
				See also [method lerp] which performs the reverse of this operation.

		</method>
		<method name="is_equal_approx">
			<return type="bool" />
			<argument index="0" name="a" type="float" />
			<argument index="1" name="b" type="float" />
			<description>
				Returns [code]true[/code] if [code]a[/code] and [code]b[/code] are approximately equal to each other.
				Here, approximately equal means that [code]a[/code] and [code]b[/code] are within a small internal epsilon of each other, which scales with the magnitude of the numbers.
				Infinity values of the same sign are considered equal.
			</description>
		</method>
		<method name="is_inf">
			<return type="bool" />
			<argument index="0" name="s" type="float" />
			<description>
				Returns whether [code]s[/code] is an infinity value (either positive infinity or negative infinity).

		<method name="is_zero_approx">
			<return type="bool" />
			<argument index="0" name="s" type="float" />
			<description>
				Returns [code]true[/code] if [code]s[/code] is zero or almost zero.
				This method is faster than using [method is_equal_approx] with one value as zero.
			</description>
		</method>
		<method name="len">
			<return type="int" />
			<argument index="0" name="var" type="Variant" />
			<description>

			</description>
		</method>
		<method name="lerp">
			<return type="Variant" />
			<argument index="0" name="from" type="Variant" />
			<argument index="1" name="to" type="Variant" />
			<argument index="2" name="weight" type="float" />
			<description>
				Linearly interpolates between two values by the factor defined in [code]weight[/code]. To perform interpolation, [code]weight[/code] should be between [code]0.0[/code] and [code]1.0[/code] (inclusive). However, values outside this range are allowed and can be used to perform [i]extrapolation[/i].
				If the [code]from[/code] and [code]to[/code] arguments are of type [int] or [float], the return value is a [float].
				If both are of the same vector type ([Vector2], [Vector3] or [Color]), the return value will be of the same type ([code]lerp[/code] then calls the vector type's [code]linear_interpolate[/code] method).
				[codeblock]
				lerp(0, 4, 0.75) # Returns 3.0
				lerp(Vector2(1, 5), Vector2(3, 2), 0.5) # Returns Vector2(2, 3.5)
				[/codeblock]
				See also [method inverse_lerp] which performs the reverse of this operation. To perform eased interpolation with [method lerp], combine it with [method ease] or [method smoothstep].
			</description>
		</method>
		<method name="lerp_angle">
			<return type="float" />
			<argument index="0" name="from" type="float" />
			<argument index="1" name="to" type="float" />
			<argument index="2" name="weight" type="float" />
			<description>
				Linearly interpolates between two angles (in radians) by a normalized value.
				Similar to [method lerp], but interpolates correctly when the angles wrap around [constant @GDScript.TAU]. To perform eased interpolation with [method lerp_angle], combine it with [method ease] or [method smoothstep].
				[codeblock]
				extends Sprite
				var elapsed = 0.0
				func _process(delta):
				    var min_angle = deg2rad(0.0)
				    var max_angle = deg2rad(90.0)
				    rotation = lerp_angle(min_angle, max_angle, elapsed)
				    elapsed += delta
				[/codeblock]
				[b]Note:[/b] This method lerps through the shortest path between [code]from[/code] and [code]to[/code]. However, when these two angles are approximately [code]PI + k * TAU[/code] apart for any integer [code]k[/code], it's not obvious which way they lerp due to floating-point precision errors. For example, [code]lerp_angle(0, PI, weight)[/code] lerps counter-clockwise, while [code]lerp_angle(0, PI + 5 * TAU, weight)[/code] lerps clockwise.
			</description>
		</method>
		<method name="linear2db">
			<return type="float" />
			<argument index="0" name="nrg" type="float" />
			<description>
				Converts from linear energy to decibels (audio). This can be used to implement volume sliders that behave as expected (since volume isn't linear). Example:
				[codeblock]
				# "Slider" refers to a node that inherits Range such as HSlider or VSlider.
				# Its range must be configured to go from 0 to 1.
				# Change the bus name if you'd like to change the volume of a specific bus only.
				AudioServer.set_bus_volume_db(AudioServer.get_bus_index("Master"), linear2db($Slider.value))

			<argument 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.

		<method name="parse_json">
			<return type="Variant" />
			<argument index="0" name="json" type="String" />
			<description>
				Parse JSON text to a Variant. (Use [method typeof] to check if the Variant's type is what you expect.)
				[b]Note:[/b] The JSON specification does not define integer or float types, but only a [i]number[/i] type. Therefore, parsing a JSON text will convert all numerical values to [float] types.
				[b]Note:[/b] JSON objects do not preserve key order like Godot dictionaries, thus, you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:
				[codeblock]
				var p = JSON.parse('["hello", "world", "!"]')
				if typeof(p.result) == TYPE_ARRAY:
				    print(p.result[0]) # Prints "hello"
				else:

		<method name="preload">
			<return type="Resource" />
			<argument 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.

		<method name="weakref">
			<return type="WeakRef" />
			<argument index="0" name="obj" type="Object" />
			<description>
				Returns a weak reference to an object.
				A weak reference to an object is not enough to keep the object alive: when the only remaining references to a referent are weak references, garbage collection is free to destroy the referent and reuse its memory for something else. However, until the object is actually destroyed the weak reference may return the object even if there are no strong references to it.

		<method name="wrapf">
			<return type="float" />
			<argument index="0" name="value" type="float" />
			<argument index="1" name="min" type="float" />
			<argument index="2" name="max" type="float" />
			<description>
				Wraps float [code]value[/code] between [code]min[/code] and [code]max[/code].
				Usable for creating loop-alike behavior or infinite surfaces.
				[codeblock]
				# Infinite loop between 5.0 and 9.9
				value = wrapf(value + 0.1, 5.0, 10.0)
				[/codeblock]
				[codeblock]
				# Infinite rotation (in radians)
				angle = wrapf(angle + 0.1, 0.0, TAU)
				[/codeblock]
				[codeblock]
				# Infinite rotation (in radians)
				angle = wrapf(angle + 0.1, -PI, PI)
				[/codeblock]
				[b]Note:[/b] If [code]min[/code] is [code]0[/code], this is equivalent to [method fposmod], so prefer using that instead.
				[code]wrapf[/code] is more flexible than using the [method fposmod] approach by giving the user control over the minimum value.

		<method name="yield">
			<return type="GDScriptFunctionState" />
			<argument index="0" name="object" type="Object" default="null" />
			<argument index="1" name="signal" type="String" default="&quot;&quot;" />
			<description>
				Stops the function execution and returns the current suspended state to the calling function.
				From the caller, call [method GDScriptFunctionState.resume] on the state to resume execution. This invalidates the state. Within the resumed function, [code]yield()[/code] returns whatever was passed to the [code]resume()[/code] function call.
				If passed an object and a signal, the execution is resumed when the object emits the given signal. In this case, [code]yield()[/code] returns the argument passed to [code]emit_signal()[/code] if the signal takes only one argument, or an array containing all the arguments passed to [code]emit_signal()[/code] if the signal takes multiple arguments.
				You can also use [code]yield[/code] to wait for a function to finish:
				[codeblock]
				func _ready():
				    yield(countdown(), "completed") # waiting for the countdown() function to complete
				    print('Ready')

				func countdown():
				    yield(get_tree(), "idle_frame") # returns a GDScriptFunctionState object to _ready()
				    print(3)
				    yield(get_tree().create_timer(1.0), "timeout")
				    print(2)
				    yield(get_tree().create_timer(1.0), "timeout")
				    print(1)
				    yield(get_tree().create_timer(1.0), "timeout")

				# prints:
				# 3
				# 2
				# 1
				# Ready
				[/codeblock]
				When yielding on a function, the [code]completed[/code] signal will be emitted automatically when the function returns. It can, therefore, be used as the [code]signal[/code] parameter of the [code]yield[/code] method to resume.
				In order to yield on a function, the resulting function should also return a [code]GDScriptFunctionState[/code]. Notice [code]yield(get_tree(), "idle_frame")[/code] from the above example.

		<constant name="PI" value="3.141593">
			Constant that represents how many times the diameter of a circle fits around its perimeter. This is equivalent to [code]TAU / 2[/code].
		</constant>
		<constant name="TAU" value="6.283185">
			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.
