+			<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

+			<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

+		</method>
+		<method name="bytes2var">

+		</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].

+		<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

+		</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]

+				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.

+			<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")

+			<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).

+			<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>
+				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].

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.

+				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.

+			<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.
