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.
|
|
[b]Scene tree:[/b] The [SceneTree] contains the active tree of nodes. When a node is added to the scene tree, it receives the [constant 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 [constant 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 the [member owner] property. 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 Object.free] or [method queue_free], it will also free all its children.
|
|
[b]Groups:[/b] Nodes can be added to as many groups as you want to be easy to manage, you could create groups like "enemies" or "collectables" for example, depending on your game. See [method add_to_group], [method is_in_group] and [method remove_from_group]. You can then retrieve all nodes in these groups, iterate them and even call methods on groups via the methods on [SceneTree].
|
|
[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). To identify which node receives the RPC call, Godot will use its [NodePath] (make sure node names are the same on all peers). Also, take a look at the high-level networking tutorial and corresponding demos.

<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 [constant NOTIFICATION_ENTER_TREE] notification in [method Object._notification].

|
|
<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 [constant 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>
|
|
The string returned from this method is displayed as a warning in the Scene Dock if the script that overrides it is a [code]tool[/code] script.
|
|
Returning an empty string produces no warning.
|
|
Call [method update_configuration_warning] when the warning needs to be updated for this node.

</return>
|
|
<argument index="0" name="event" type="InputEvent">
|
|
</argument>
|
|
<description>
|
|
Called when there is an input event. The input event propagates up through the node tree until a node consumes it.
|
|
It is only called if input processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_process_input].
|
|
To consume the input event and stop it propagating further to other nodes, [method Viewport.set_input_as_handled] can be called.
|
|
For gameplay input, [method _unhandled_input] and [method _unhandled_key_input] are usually a better fit as they allow the GUI to intercept the events first.

<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 [constant NOTIFICATION_PHYSICS_PROCESS] notification in [method Object._notification].

<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].
|

|
|
<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 [constant NOTIFICATION_READY] notification in [method Object._notification]. See also the [code]onready[/code] keyword for variables.
|
|
Usually used for initialization. For even earlier initialization, [method Object._init] may be used. See also [method _enter_tree].
|
|
[b]Note:[/b] [method _ready] may be called only once for each node. After removing a node from the scene tree and adding again, [code]_ready[/code] will not be called for the second time. This can be bypassed with requesting another call with [method request_ready], which may be called anywhere before adding the node again.

<description>
|
|
Called when an [InputEvent] hasn't been consumed by [method _input] or any GUI. The input event propagates up through the node tree until a node consumes it.
|
|
It is only called if unhandled input processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_process_unhandled_input].
|
|
To consume the input event and stop it propagating further to other nodes, [method Viewport.set_input_as_handled] can be called.
|
|
For gameplay input, this and [method _unhandled_key_input] are usually a better fit than [method _input] as they allow the GUI to intercept the events first.

|
|
<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.
|
|
If [code]legible_unique_name[/code] is [code]true[/code], the child node will have an human-readable name based on the name of the node being instanced instead of its type.
|
|
[b]Note:[/b] If the child node already has a parent, the function will fail. Use [method remove_child] first to remove the node from its current parent. For example:
|
|
[codeblock]
|
|
if child_node.get_parent():
|
|
child_node.get_parent().remove_child(child_node)
|
|
add_child(child_node)
|
|
[/codeblock]
|
|
If you need the child node to be added below a specific node in the list of children, use [method add_child_below_node] instead of this method.
|
|
[b]Note:[/b] If you want a child to be persisted to a [PackedScene], you must set [member owner] in addition to calling [method add_child]. This is typically relevant for [url=https://godot.readthedocs.io/en/latest/tutorials/misc/running_code_in_the_editor.html]tool scripts[/url] and [url=https://godot.readthedocs.io/en/latest/tutorials/plugins/editor/index.html]editor plugins[/url]. If [method add_child] is called without setting [member owner], the newly added [Node] will not be visible in the scene tree, though it will be visible in the 2D/3D view.

<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]). See notes in the description, and the group methods in [SceneTree].
|
|
The [code]persistent[/code] option is used when packing node to [PackedScene] and saving to file. Non-persistent groups aren't stored.

|
Duplicates the node, returning a new node.
|
|
You can fine-tune the behavior using the [code]flags[/code] (see [enum DuplicateFlags]).
|
|
[b]Note:[/b] It will not work properly if the node contains a script with constructor arguments (i.e. needs to supply arguments to [method Object._init] method). In that case, the node will be duplicated without a script.

<description>
|

Finds a descendant of this node whose name matches [code]mask[/code] as in [method String.match] (i.e. case-sensitive, but [code]"*"[/code] matches zero or more characters and [code]"?"[/code] matches any single character except [code]"."[/code]).
|
|
[b]Note:[/b] It does not match against the full path, just against individual node names.
|
|
If [code]owned[/code] is [code]true[/code], this method only finds nodes whose owner is this node. This is especially important for scenes instantiated through a script, because those scenes don't have an owner.

<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 an error is logged. Attempts to access methods on the return value will result in an "Attempt to call <method> on a null instance." error.
|
|
[b]Note:[/b] Fetching absolute paths only works when the node is inside the scene tree (see [method is_inside_tree]).
|
|
[b]Example:[/b] 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
|
|
/root/Swamp/Goblin
|
|
[/codeblock]
|
|
Possible paths are:
|
|
[codeblock]
|
|
get_node("Sword")
|
|
get_node("Backpack/Dagger")
|
|
get_node("../Swamp/Alligator")
|
|
get_node("/root/MyGame")

<argument index="0" name="path" type="NodePath">

|
|
<description>
|
|
Fetches a node and one of its resources as specified by the [NodePath]'s subname (e.g. [code]Area2D/CollisionShape2D:shape[/code]). If several nested resources are specified in the [NodePath], the last one will be fetched.
|
|
The return value is an array of size 3: the first index points to the [Node] (or [code]null[/code] if not found), the second index points to the [Resource] (or [code]null[/code] if not found), and the third index is the remaining [NodePath], if any.
|
|
For example, assuming that [code]Area2D/CollisionShape2D[/code] is a valid node and that its [code]shape[/code] property has been assigned a [RectangleShape2D] resource, one could have this kind of output:
|
|
[codeblock]
|
|
print(get_node_and_resource("Area2D/CollisionShape2D")) # [[CollisionShape2D:1161], Null, ]
|
|
print(get_node_and_resource("Area2D/CollisionShape2D:shape")) # [[CollisionShape2D:1161], [RectangleShape2D:1156], ]
|
|
print(get_node_and_resource("Area2D/CollisionShape2D:shape:extents")) # [[CollisionShape2D:1161], [RectangleShape2D:1156], :extents]

Sends a remote procedure call request for the given [code]method[/code] to peers on the network (and locally), optionally sending all additional arguments as arguments to the method called by the RPC. The call request will only be received by nodes with the same [NodePath], including the exact same node name. Behaviour depends on the RPC configuration for the given method, see [method rpc_config]. Methods are not exposed to RPCs by default. See also [method rset] and [method rset_config] for properties. Returns an empty [Variant].
|

[b]Note:[/b] You can only safely use RPCs on clients after you received the [code]connected_to_server[/code] signal from the [SceneTree]. You also need to keep track of the connection state, either by the [SceneTree] signals like [code]server_disconnected[/code] or by checking [code]SceneTree.network_peer.get_connection_status() == CONNECTION_CONNECTED[/code].

<member name="custom_multiplayer" type="MultiplayerAPI" setter="set_custom_multiplayer" getter="get_custom_multiplayer">
|
|
The override to the default [MultiplayerAPI]. Set to [code]null[/code] to use the default [SceneTree] one.
|
|
</member>
|
|
<member name="filename" type="String" setter="set_filename" getter="get_filename">
|
|
When a scene is instanced from a file, its topmost node contains the filename from which it was loaded.
|
|
</member>
|
|
<member name="multiplayer" type="MultiplayerAPI" setter="" getter="get_multiplayer">
|
|
The [MultiplayerAPI] instance associated with this node. Either the [member custom_multiplayer], or the default SceneTree one (if inside tree).
|
|
</member>
|
|
<member name="name" type="StringName" setter="set_name" getter="get_name">
|
|
The name of the node. This name is unique among the siblings (other child nodes from the same parent). When set to an existing name, the node will be automatically renamed.
|
|
</member>
|
|
<member name="owner" type="Node" setter="set_owner" getter="get_owner">
|
|
The node owner. A node can have any other node as owner (as long as it is a valid parent, grandparent, etc. ascending in the tree). When saving a node (using [PackedScene]), all the nodes it owns will be saved with it. This allows for the creation of complex [SceneTree]s, with instancing and subinstancing.

</member>
|
|
<member name="process_priority" type="int" setter="set_process_priority" getter="get_process_priority" default="0">
|
|
The node's priority in the execution order of the enabled processing callbacks (i.e. [constant NOTIFICATION_PROCESS], [constant NOTIFICATION_PHYSICS_PROCESS] and their internal counterparts). Nodes whose process priority value is [i]lower[/i] will have their processing callbacks executed first.
