	<description>
		Nodes are Godot's building blocks. They can be assigned as the child of another node, resulting in a tree arrangement. A given node can contain any number of nodes as children with the requirement that all siblings (direct children of a node) should have unique names.
		A tree of nodes is called a [i]scene[/i]. Scenes can be saved to the disk and then instanced into other scenes. This allows for very high flexibility in the architecture and data model of Godot projects. Nodes can also optionally be added to groups. This makes it possible to access a number of nodes from code (an "enemies" group, for example) to perform grouped actions.
		[b]Scene tree:[/b] The [SceneTree] contains the active tree of nodes. When a node is added to the scene tree, it receives the NOTIFICATION_ENTER_TREE notification and its [method _enter_tree] callback is triggered. Child nodes are always added [i]after[/i] their parent node, i.e. the [method _enter_tree] callback of a parent node will be triggered before its child's.
		Once all nodes have been added in the scene tree, they receive the NOTIFICATION_READY notification and their respective [method _ready] callbacks are triggered. For groups of nodes, the [method _ready] callback is called in reverse order, starting with the children and moving up to the parent nodes.
		This means that when adding a node to the scene tree, the following order will be used for the callbacks: [method _enter_tree] of the parent, [method _enter_tree] of the children, [method _ready] of the children and finally [method _ready] of the parent (recursively for the entire scene tree).
		[b]Processing:[/b] Nodes can override the "process" state, so that they receive a callback on each frame requesting them to process (do something). Normal processing (callback [method _process], toggled with [method set_process]) happens as fast as possible and is dependent on the frame rate, so the processing time [i]delta[/i] is passed as an argument. Physics processing (callback [method _physics_process], toggled with [method set_physics_process]) happens a fixed number of times per second (60 by default) and is useful for code related to the physics engine.
		Nodes can also process input events. When present, the [method _input] function will be called for each input that the program receives. In many cases, this can be overkill (unless used for simple projects), and the [method _unhandled_input] function might be preferred; it is called when the input event was not handled by anyone else (typically, GUI [Control] nodes), ensuring that the node only receives the events that were meant for it.
		To keep track of the scene hierarchy (especially when instancing scenes into other scenes), an "owner" can be set for the node with [method set_owner]. This keeps track of who instanced what. This is mostly useful when writing editors and tools, though.
		Finally, when a node is freed with [method free] or [method queue_free], it will also free all its children.
		[b]Networking with nodes:[/b] After connecting to a server (or making one, see [NetworkedMultiplayerENet]) it is possible to use the built-in RPC (remote procedure call) system to communicate over the network. By calling [method rpc] with a method name, it will be called locally and in all connected peers (peers = clients and the server that accepts connections), with behaviour varying depending on the network mode ([method set_network_mode]) of the receiving peer. To identify which node receives the RPC call Godot will use its [NodePath] (make sure node names are the same on all peers).

	<methods>
		<method name="_enter_tree" qualifiers="virtual">
			<return type="void">
			</return>
			<description>
				Called when the node enters the [SceneTree] (e.g. upon instancing, scene changing, or after calling [method add_child] in a script). If the node has children, its [method _enter_tree] callback will be called first, and then that of the children.
				Corresponds to the NOTIFICATION_ENTER_TREE notification in [method Object._notification].
			</description>
		</method>
		<method name="_exit_tree" qualifiers="virtual">
			<return type="void">
			</return>
			<description>
				Called when the node is about to leave the [SceneTree] (e.g. upon freeing, scene changing, or after calling [method remove_child] in a script). If the node has children, its [method _exit_tree] callback will be called last, after all its children have left the tree.
				Corresponds to the NOTIFICATION_EXIT_TREE notification in [method Object._notification] and signal [signal tree_exiting]. To get notified when the node has already left the active tree, connect to the [signal tree_exited]
			</description>
		</method>
		<method name="_input" qualifiers="virtual">
			<return type="void">
			</return>
			<argument index="0" name="event" type="InputEvent">
			</argument>
			<description>
				Called when there is an input event. The input event propagates through the node tree until a node consumes it.

			<return type="void">
			</return>
			<argument index="0" name="delta" type="float">
			</argument>
			<description>
				Called during the physics processing step of the main loop. Physics processing means that the frame rate is synced to the physics, i.e. the [code]delta[/code] variable should be constant.
				It is only called if physics processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_physics_process].
				Corresponds to the NOTIFICATION_PHYSICS_PROCESS notification in [method Object._notification].

			<return type="void">
			</return>
			<argument index="0" name="delta" type="float">
			</argument>
			<description>
				Called during the processing step of the main loop. Processing happens at every frame and as fast as possible, so the [code]delta[/code] time since the previous frame is not constant.
				It is only called if processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_process].
				Corresponds to the NOTIFICATION_PROCESS notification in [method Object._notification].
			</description>
		</method>
		<method name="_ready" qualifiers="virtual">
			<return type="void">
			</return>
			<description>
				Called when the node is "ready", i.e. when both the node and its children have entered the scene tree. If the node has children, their [method _ready] callbacks get triggered first, and the parent node will receive the ready notification afterwards.
				Corresponds to the NOTIFICATION_READY notification in [method Object._notification].

			</argument>
			<argument index="1" name="legible_unique_name" type="bool" default="false">
			</argument>
			<description>
				Adds a child node. Nodes can have any number of children, but every child must have a unique name. Child nodes are automatically deleted when the parent node is deleted, so an entire scene can be removed by deleting its topmost node.
				Setting "legible_unique_name" [code]true[/code] creates child nodes with human-readable names, based on the name of the node being instanced instead of its type.

			<description>
				Adds the node to a group. Groups are helpers to name and organize a subset of nodes, for example "enemies" or "collectables". A node can be in any number of groups. Nodes can be assigned a group at any time, but will not be added until they are inside the scene tree (see [method is_inside_tree]).

			<return type="Node">
			</return>
			<argument index="0" name="idx" type="int">

		<method name="get_node" qualifiers="const">
			<return type="Node">
			</return>
			<argument index="0" name="path" type="NodePath">
			</argument>
			<description>
				Fetches a node. The [NodePath] can be either a relative path (from the current node) or an absolute path (in the scene tree) to a node. If the path does not exist, a [code]null instance[/code] is returned and attempts to access it will result in an "Attempt to call &lt;method&gt; on a null instance." error.
				Note: fetching absolute paths only works when the node is inside the scene tree (see [method is_inside_tree]).
				[i]Example:[/i] Assume your current node is Character and the following tree:
				[codeblock]
				/root
				/root/Character
				/root/Character/Sword
				/root/Character/Backpack/Dagger
				/root/MyGame
				/root/Swamp/Alligator
				/root/Swamp/Mosquito
