	<brief_description>
		Base class for all other classes in the engine.
	</brief_description>
	<description>
		An advanced [Variant] type. All classes in the engine inherit from Object. Each class may define new properties, methods or signals, which are available to all inheriting classes. For example, a [Sprite2D] instance is able to call [method Node.add_child] because it inherits from [Node].
		You can create new instances, using [code]Object.new()[/code] in GDScript, or [code]new GodotObject[/code] in C#.
		To delete an Object instance, call [method free]. This is necessary for most classes inheriting Object, because they do not manage memory on their own, and will otherwise cause memory leaks when no longer in use. There are a few classes that perform memory management. For example, [RefCounted] (and by extension [Resource]) deletes itself when no longer referenced, and [Node] deletes its children when freed.
		Objects can have a [Script] attached to them. Once the [Script] is instantiated, it effectively acts as an extension to the base class, allowing it to define and inherit new properties, methods and signals.
		Inside a [Script], [method _get_property_list] may be overridden to customize properties in several ways. This allows them to be available to the editor, display as lists of options, sub-divide into groups, save on disk, etc. Scripting languages offer easier ways to customize properties, such as with the [annotation @GDScript.@export] annotation.
		Godot is very dynamic. An object's script, and therefore its properties, methods and signals, can be changed at run-time. Because of this, there can be occasions where, for example, a property required by a method may not exist. To prevent run-time errors, see methods such as [method set], [method get], [method call], [method has_method], [method has_signal], etc. Note that these methods are [b]much[/b] slower than direct references.
		In GDScript, you can also check if a given property, method, or signal name exists in an object with the [code]in[/code] operator:
		[codeblock]
		var node = Node.new()
		print("name" in node)         # Prints true
		print("get_parent" in node)   # Prints true
		print("tree_entered" in node) # Prints true
		print("unknown" in node)      # Prints false
		[/codeblock]
		Notifications are [int] constants commonly sent and received by objects. For example, on every rendered frame, the [SceneTree] notifies nodes inside the tree with a [constant Node.NOTIFICATION_PROCESS]. The nodes receive it and may call [method Node._process] to update. To make use of notifications, see [method notification] and [method _notification].
		Lastly, every object can also contain metadata (data about data). [method set_meta] can be useful to store information that the object itself does not depend on. To keep your code clean, making excessive use of metadata is discouraged.
		[b]Note:[/b] Unlike references to a [RefCounted], references to an object stored in a variable can become invalid without being set to [code]null[/code]. To check if an object has been deleted, do [i]not[/i] compare it against [code]null[/code]. Instead, use [method @GlobalScope.is_instance_valid]. It's also recommended to inherit from [RefCounted] for classes storing data instead of [Object].
		[b]Note:[/b] The [code]script[/code] is not exposed like most properties. To set or get an object's [Script] in code, use [method set_script] and [method get_script], respectively.

		<method name="_get_property_list" qualifiers="virtual">
			<return type="Dictionary[]" />
			<description>
				Override this method to provide a custom list of additional properties to handle by the engine.
				Should return a property list, as an [Array] of dictionaries. The result is added to the array of [method get_property_list], and should be formatted in the same way. Each [Dictionary] must at least contain the [code]name[/code] and [code]type[/code] entries.
				You can use [method _property_can_revert] and [method _property_get_revert] to customize the default values of the properties added by this method.
				The example below displays a list of numbers shown as words going from [code]ZERO[/code] to [code]FIVE[/code], with [code]number_count[/code] controlling the size of the list:
				[codeblocks]
				[gdscript]
				@tool

				[b]Note:[/b] This method is intended for advanced purposes. For most common use cases, the scripting languages offer easier ways to handle properties. See [annotation @GDScript.@export], [annotation @GDScript.@export_enum], [annotation @GDScript.@export_group], etc. If you want to customize exported properties, use [method _validate_property].
				[b]Note:[/b] If the object's script is not [annotation @GDScript.@tool], this method will not be called in the editor.
			</description>
		</method>
		<method name="_init" qualifiers="virtual">
			<return type="void" />
			<description>
				Called when the object's script is instantiated, oftentimes after the object is initialized in memory (through [code]Object.new()[/code] in GDScript, or [code]new GodotObject[/code] in C#). It can be also defined to take in parameters. This method is similar to a constructor in most programming languages.
				[b]Note:[/b] If [method _init] is defined with [i]required[/i] parameters, the Object with script may only be created directly. If any other means (such as [method PackedScene.instantiate] or [method Node.duplicate]) are used, the script's initialization will fail.
			</description>
		</method>
		<method name="_iter_get" qualifiers="virtual">
			<return type="Variant" />
			<param index="0" name="iter" type="Variant" />
			<description>
				Returns the current iterable value. [param iter] stores the iteration state, but unlike [method _iter_init] and [method _iter_next] the state is supposed to be read-only, so there is no [Array] wrapper.
			</description>
		</method>
		<method name="_iter_init" qualifiers="virtual">
			<return type="bool" />
			<param index="0" name="iter" type="Array" />
			<description>
				Initializes the iterator. [param iter] stores the iteration state. Since GDScript does not support passing arguments by reference, a single-element array is used as a wrapper. Returns [code]true[/code] so long as the iterator has not reached the end.
				Example:
				[codeblock]
				class MyRange:
				    var _from
				    var _to

				    func _init(from, to):
				        assert(from &lt;= to)
				        _from = from
				        _to = to

				    func _iter_init(iter):
				        iter[0] = _from
				        return iter[0] &lt; _to

				    func _iter_next(iter):
				        iter[0] += 1
				        return iter[0] &lt; _to

				    func _iter_get(iter):
				        return iter

				func _ready():
				    var my_range = MyRange.new(2, 5)
				    for x in my_range:
				        print(x) # Prints 2, 3, 4.
				[/codeblock]
				[b]Note:[/b] Alternatively, you can ignore [param iter] and use the object's state instead, see [url=$DOCS_URL/tutorials/scripting/gdscript/gdscript_advanced.html#custom-iterators]online docs[/url] for an example. Note that in this case you will not be able to reuse the same iterator instance in nested loops. Also, make sure you reset the iterator state in this method if you want to reuse the same instance multiple times.
			</description>
		</method>
		<method name="_iter_next" qualifiers="virtual">
			<return type="bool" />
			<param index="0" name="iter" type="Array" />
			<description>
				Moves the iterator to the next iteration. [param iter] stores the iteration state. Since GDScript does not support passing arguments by reference, a single-element array is used as a wrapper. Returns [code]true[/code] so long as the iterator has not reached the end.
			</description>
		</method>
		<method name="_notification" qualifiers="virtual">
			<return type="void" />
			<param index="0" name="what" type="int" />
			<description>
				Called when the object receives a notification, which can be identified in [param what] by comparing it with a constant. See also [method notification].
				[codeblocks]
				[gdscript]
				func _notification(what):
				    if what == NOTIFICATION_PREDELETE:
				        print("Goodbye!")
				[/gdscript]
				[csharp]
				public override void _Notification(int what)
				{
				    if (what == NotificationPredelete)
				    {
				        GD.Print("Goodbye!");
				    }
				}
				[/csharp]
				[/codeblocks]
				[b]Note:[/b] The base [Object] defines a few notifications ([constant NOTIFICATION_POSTINITIALIZE] and [constant NOTIFICATION_PREDELETE]). Inheriting classes such as [Node] define a lot more notifications, which are also received by this method.
			</description>
		</method>
		<method name="_property_can_revert" qualifiers="virtual">
			<return type="bool" />
			<param index="0" name="property" type="StringName" />
			<description>
				Override this method to customize the given [param property]'s revert behavior. Should return [code]true[/code] if the [param property] has a custom default value and is revertible in the Inspector dock. Use [method _property_get_revert] to specify the [param property]'s default value.
				[b]Note:[/b] This method must return consistently, regardless of the current value of the [param property].
			</description>
		</method>
		<method name="_property_get_revert" qualifiers="virtual">
			<return type="Variant" />
			<param index="0" name="property" type="StringName" />
			<description>
				Override this method to customize the given [param property]'s revert behavior. Should return the default value for the [param property]. If the default value differs from the [param property]'s current value, a revert icon is displayed in the Inspector dock.
				[b]Note:[/b] [method _property_can_revert] must also be overridden for this method to be called.
			</description>
		</method>
		<method name="_set" qualifiers="virtual">
			<return type="bool" />
			<param index="0" name="property" type="StringName" />
			<param index="1" name="value" type="Variant" />
			<description>
				Override this method to customize the behavior of [method set]. Should set the [param property] to [param value] and return [code]true[/code], or [code]false[/code] if the [param property] should be handled normally. The [i]exact[/i] way to set the [param property] is up to this method's implementation.
				Combined with [method _get] and [method _get_property_list], this method allows defining custom properties, which is particularly useful for editor plugins. Note that a property [i]must[/i] be present in [method get_property_list], otherwise this method will not be called.

				Calls the [param method] on the object during idle time. Always returns [code]null[/code], [b]not[/b] the method's result.
				Idle time happens mainly at the end of process and physics frames. In it, deferred calls will be run until there are none left, which means you can defer calls from other deferred calls and they'll still be run in the current idle time cycle. This means you should not call a method deferred from itself (or from a method called by it), as this causes infinite recursion the same way as if you had called the method directly.

			<description>
				If this method is called during [constant NOTIFICATION_PREDELETE], this object will reject being freed and will remain allocated. This is mostly an internal function used for error handling to avoid the user from freeing objects when they are not intended to.

		<method name="connect">
			<return type="int" enum="Error" />
			<param index="0" name="signal" type="StringName" />
			<param index="1" name="callable" type="Callable" />
			<param index="2" name="flags" type="int" default="0" />
			<description>
				Connects a [param signal] by name to a [param callable]. Optional [param flags] can be also added to configure the connection's behavior (see [enum ConnectFlags] constants).
				A signal can only be connected once to the same [Callable]. If the signal is already connected, this method returns [constant ERR_INVALID_PARAMETER] and pushes an error message, unless the signal is connected with [constant CONNECT_REFERENCE_COUNTED]. To prevent this, use [method is_connected] first to check for existing connections.
				If the [param callable]'s object is freed, the connection will be lost.
				[b]Examples with recommended syntax:[/b]
				Connecting signals is one of the most common operations in Godot and the API gives many options to do so, which are described further down. The code block below shows the recommended approach.
				[codeblocks]
				[gdscript]
				func _ready():
				    var button = Button.new()
				    # `button_down` here is a Signal variant type, and we thus call the Signal.connect() method, not Object.connect().
				    # See discussion below for a more in-depth overview of the API.
				    button.button_down.connect(_on_button_down)

				    # This assumes that a `Player` class exists, which defines a `hit` signal.
				    var player = Player.new()
				    # We use Signal.connect() again, and we also use the Callable.bind() method,
				    # which returns a new Callable with the parameter binds.
				    player.hit.connect(_on_player_hit.bind("sword", 100))

				func _on_button_down():
				    print("Button down!")

				func _on_player_hit(weapon_type, damage):
				    print("Hit with weapon %s for %d damage." % [weapon_type, damage])
				[/gdscript]
				[csharp]
				public override void _Ready()
				{
				    var button = new Button();
				    // C# supports passing signals as events, so we can use this idiomatic construct:
				    button.ButtonDown += OnButtonDown;

				    // This assumes that a `Player` class exists, which defines a `Hit` signal.
				    var player = new Player();
				    // We can use lambdas when we need to bind additional parameters.
				    player.Hit += () =&gt; OnPlayerHit("sword", 100);
				}

				private void OnButtonDown()
				{
				    GD.Print("Button down!");
				}

				private void OnPlayerHit(string weaponType, int damage)
				{
				    GD.Print($"Hit with weapon {weaponType} for {damage} damage.");
				}
				[/csharp]
				[/codeblocks]
				[b][code skip-lint]Object.connect()[/code] or [code skip-lint]Signal.connect()[/code]?[/b]
				As seen above, the recommended method to connect signals is not [method Object.connect]. The code block below shows the four options for connecting signals, using either this legacy method or the recommended [method Signal.connect], and using either an implicit [Callable] or a manually defined one.
				[codeblocks]
				[gdscript]
				func _ready():
				    var button = Button.new()
				    # Option 1: Object.connect() with an implicit Callable for the defined function.
				    button.connect("button_down", _on_button_down)
				    # Option 2: Object.connect() with a constructed Callable using a target object and method name.
				    button.connect("button_down", Callable(self, "_on_button_down"))
				    # Option 3: Signal.connect() with an implicit Callable for the defined function.
				    button.button_down.connect(_on_button_down)
				    # Option 4: Signal.connect() with a constructed Callable using a target object and method name.
				    button.button_down.connect(Callable(self, "_on_button_down"))

				func _on_button_down():
				    print("Button down!")
				[/gdscript]
				[csharp]
				public override void _Ready()
				{
				    var button = new Button();
				    // Option 1: In C#, we can use signals as events and connect with this idiomatic syntax:
				    button.ButtonDown += OnButtonDown;
				    // Option 2: GodotObject.Connect() with a constructed Callable from a method group.
				    button.Connect(Button.SignalName.ButtonDown, Callable.From(OnButtonDown));
				    // Option 3: GodotObject.Connect() with a constructed Callable using a target object and method name.
				    button.Connect(Button.SignalName.ButtonDown, new Callable(this, MethodName.OnButtonDown));
				}

				private void OnButtonDown()
				{
				    GD.Print("Button down!");
				}
				[/csharp]
				[/codeblocks]
				While all options have the same outcome ([code]button[/code]'s [signal BaseButton.button_down] signal will be connected to [code]_on_button_down[/code]), [b]option 3[/b] offers the best validation: it will print a compile-time error if either the [code]button_down[/code] [Signal] or the [code]_on_button_down[/code] [Callable] are not defined. On the other hand, [b]option 2[/b] only relies on string names and will only be able to validate either names at runtime: it will print a runtime error if [code]"button_down"[/code] doesn't correspond to a signal, or if [code]"_on_button_down"[/code] is not a registered method in the object [code]self[/code]. The main reason for using options 1, 2, or 4 would be if you actually need to use strings (e.g. to connect signals programmatically based on strings read from a configuration file). Otherwise, option 3 is the recommended (and fastest) method.
				[b]Binding and passing parameters:[/b]
				The syntax to bind parameters is through [method Callable.bind], which returns a copy of the [Callable] with its parameters bound.
				When calling [method emit_signal] or [method Signal.emit], the signal parameters can be also passed. The examples below show the relationship between these signal parameters and bound parameters.
				[codeblocks]
				[gdscript]
				func _ready():
				    # This assumes that a `Player` class exists, which defines a `hit` signal.
				    var player = Player.new()
				    # Using Callable.bind().
				    player.hit.connect(_on_player_hit.bind("sword", 100))

				    # Parameters added when emitting the signal are passed first.
				    player.hit.emit("Dark lord", 5)

				# We pass two arguments when emitting (`hit_by`, `level`),
				# and bind two more arguments when connecting (`weapon_type`, `damage`).
				func _on_player_hit(hit_by, level, weapon_type, damage):
				    print("Hit by %s (level %d) with weapon %s for %d damage." % [hit_by, level, weapon_type, damage])
				[/gdscript]
				[csharp]
				public override void _Ready()
				{
				    // This assumes that a `Player` class exists, which defines a `Hit` signal.
				    var player = new Player();
				    // Using lambda expressions that create a closure that captures the additional parameters.
				    // The lambda only receives the parameters defined by the signal's delegate.
				    player.Hit += (hitBy, level) =&gt; OnPlayerHit(hitBy, level, "sword", 100);

				    // Parameters added when emitting the signal are passed first.
				    player.EmitSignal(SignalName.Hit, "Dark lord", 5);
				}

				// We pass two arguments when emitting (`hit_by`, `level`),
				// and bind two more arguments when connecting (`weapon_type`, `damage`).
				private void OnPlayerHit(string hitBy, int level, string weaponType, int damage)
				{
				    GD.Print($"Hit by {hitBy} (level {level}) with weapon {weaponType} for {damage} damage.");
				}
				[/csharp]

			<description>
				Assigns a new [param value] to the property identified by the [param property_path]. The path should be a [NodePath] relative to this object, and can use the colon character ([code]:[/code]) to access nested properties.
				[codeblocks]
				[gdscript]

		<method name="set_message_translation">
			<return type="void" />
			<param index="0" name="enable" type="bool" />
			<description>
				If set to [code]true[/code], allows the object to translate messages with [method tr] and [method tr_n]. Enabled by default. See also [method can_translate_messages].
			</description>
		</method>
		<method name="set_meta">
			<return type="void" />
			<param index="0" name="name" type="StringName" />
			<param index="1" name="value" type="Variant" />
			<description>
				Adds or changes the entry [param name] inside the object's metadata. The metadata [param value] can be any [Variant], although some types cannot be serialized correctly.
				If [param value] is [code]null[/code], the entry is removed. This is the equivalent of using [method remove_meta]. See also [method has_meta] and [method get_meta].
				[b]Note:[/b] A metadata's name must be a valid identifier as per [method StringName.is_valid_identifier] method.
				[b]Note:[/b] Metadata that has a name starting with an underscore ([code]_[/code]) is considered editor-only. Editor-only metadata is not displayed in the Inspector and should not be edited, although it can still be found by this method.
			</description>
		</method>
		<method name="set_script">
			<return type="void" />
			<param index="0" name="script" type="Variant" />
			<description>
				Attaches [param script] to the object, and instantiates it. As a result, the script's [method _init] is called. A [Script] is used to extend the object's functionality.
				If a script already exists, its instance is detached, and its property values and state are lost. Built-in property values are still kept.

		</method>
		<method name="set_translation_domain">
			<return type="void" />
			<param index="0" name="domain" type="StringName" />
			<description>
				Sets the name of the translation domain used by [method tr] and [method tr_n]. See also [TranslationServer].
			</description>
		</method>
		<method name="to_string">
			<return type="String" />
			<description>
				Returns a [String] representing the object. Defaults to [code]"&lt;ClassName#RID&gt;"[/code]. Override [method _to_string] to customize the string representation of the object.
			</description>
		</method>
		<method name="tr" qualifiers="const">
			<return type="String" />
			<param index="0" name="message" type="StringName" />
			<param index="1" name="context" type="StringName" default="&amp;&quot;&quot;" />
			<description>
				Translates a [param message], using the translation catalogs configured in the Project Settings. Further [param context] can be specified to help with the translation. Note that most [Control] nodes automatically translate their strings, so this method is mostly useful for formatted strings or custom drawn text.
				If [method can_translate_messages] is [code]false[/code], or no translation is available, this method returns the [param message] without changes. See [method set_message_translation].
				For detailed examples, see [url=$DOCS_URL/tutorials/i18n/internationalizing_games.html]Internationalizing games[/url].
				[b]Note:[/b] This method can't be used without an [Object] instance, as it requires the [method can_translate_messages] method. To translate strings in a static context, use [method TranslationServer.translate].

		<method name="tr_n" qualifiers="const">
			<return type="String" />
			<param index="0" name="message" type="StringName" />

			<param index="2" name="n" type="int" />
			<param index="3" name="context" type="StringName" default="&amp;&quot;&quot;" />
			<description>
				Translates a [param message] or [param plural_message], using the translation catalogs configured in the Project Settings. Further [param context] can be specified to help with the translation.
				If [method can_translate_messages] is [code]false[/code], or no translation is available, this method returns [param message] or [param plural_message], without changes. See [method set_message_translation].
				The [param n] is the number, or amount, of the message's subject. It is used by the translation system to fetch the correct plural form for the current language.
				For detailed examples, see [url=$DOCS_URL/tutorials/i18n/localization_using_gettext.html]Localization using gettext[/url].
				[b]Note:[/b] Negative and [float] numbers may not properly apply to some countable subjects. It's recommended to handle these cases with [method tr].
				[b]Note:[/b] This method can't be used without an [Object] instance, as it requires the [method can_translate_messages] method. To translate strings in a static context, use [method TranslationServer.translate_plural].
