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 instantiated 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] (in seconds) 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 instantiated 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 [ENetMultiplayerPeer]), 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.
|
|
[b]Note:[/b] The [code]script[/code] property is part of the [Object] class, not [Node]. It isn't exposed like most properties but does have a setter and getter ([code]set_script()[/code] and [code]get_script()[/code]).

<methods>
|
|
<method name="_enter_tree" qualifiers="virtual">
|
|
<return type="void" />
|
|
<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].
|

|
|
</method>
|
|
<method name="_exit_tree" qualifiers="virtual">
|
|
<return type="void" />
|
|
<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].
|

</method>
|
|
<method name="_get_configuration_warnings" qualifiers="virtual const">
|
|
<return type="PackedStringArray" />
|
|
<description>
|
|
The elements in the array returned from this method are displayed as warnings in the Scene dock if the script that overrides it is a [code]tool[/code] script.
|
|
Returning an empty array produces no warnings.
|
|
Call [method update_configuration_warnings] when the warnings need to be updated for this node.
|
|
[codeblock]
|
|
@export var energy = 0:
|
|
set(value):
|
|
energy = value
|
|
update_configuration_warnings()
|
|
|
|
func _get_configuration_warnings():
|
|
if energy < 0:
|
|
return ["Energy must be 0 or greater."]
|
|
else:
|
|
return []

|
|
<method name="_input" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="event" type="InputEvent" />
|
|
<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.
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not an orphan).
|

<method name="_physics_process" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="delta" type="float" />
|
|
<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 [param delta] variable should be constant. [param delta] is in seconds.
|
|
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].
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not an orphan).

<method name="_process" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="delta" type="float" />
|
|
<description>
|
|
Called during the processing step of the main loop. Processing happens at every frame and as fast as possible, so the [param delta] time since the previous frame is not constant. [param delta] is in seconds.
|
|
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 [constant NOTIFICATION_PROCESS] notification in [method Object._notification].
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not an orphan).
|
|
</description>
|
|
</method>
|
|
<method name="_ready" qualifiers="virtual">
|
|
<return type="void" />
|
|
<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] annotation 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 it again, [method _ready] will not be called a second time. This can be bypassed by requesting another call with [method request_ready], which may be called anywhere before adding the node again.

<method name="_shortcut_input" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="event" type="InputEvent" />
|
|
<description>
|
|
Called when an [InputEventKey] or [InputEventShortcut] hasn't been consumed by [method _input] or any GUI [Control] item. It is called before [method _unhandled_key_input] and [method _unhandled_input]. The input event propagates up through the node tree until a node consumes it.
|
|
It is only called if shortcut processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_process_shortcut_input].
|
|
To consume the input event and stop it propagating further to other nodes, [method Viewport.set_input_as_handled] can be called.
|
|
This method can be used to handle shortcuts. For generic GUI events, use [method _input] instead. Gameplay events should usually be handled with either [method _unhandled_input] or [method _unhandled_key_input].
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not orphan).
|
|
</description>
|
|
</method>
|
|
<method name="_unhandled_input" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="event" type="InputEvent" />
|
|
<description>
|
|
Called when an [InputEvent] hasn't been consumed by [method _input] or any GUI [Control] item. It is called after [method _shortcut_input] and after [method _unhandled_key_input]. 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 method is usually a better fit than [method _input], as GUI events need a higher priority. For keyboard shortcuts, consider using [method _shortcut_input] instead, as it is called before this method. Finally, to handle keyboard events, consider using [method _unhandled_key_input] for performance reasons.
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not an orphan).

<method name="_unhandled_key_input" qualifiers="virtual">
|
|
<return type="void" />
|
|
<param index="0" name="event" type="InputEvent" />
|
|
<description>
|
|
Called when an [InputEventKey] hasn't been consumed by [method _input] or any GUI [Control] item. It is called after [method _shortcut_input] but before [method _unhandled_input]. The input event propagates up through the node tree until a node consumes it.
|
|
It is only called if unhandled key input processing is enabled, which is done automatically if this method is overridden, and can be toggled with [method set_process_unhandled_key_input].
|
|
To consume the input event and stop it propagating further to other nodes, [method Viewport.set_input_as_handled] can be called.
|
|
This method can be used to handle Unicode character input with [kbd]Alt[/kbd], [kbd]Alt + Ctrl[/kbd], and [kbd]Alt + Shift[/kbd] modifiers, after shortcuts were handled.
|
|
For gameplay input, this and [method _unhandled_input] are usually a better fit than [method _input], as GUI events should be handled first. This method also performs better than [method _unhandled_input], since unrelated events such as [InputEventMouseMotion] are automatically filtered. For shortcuts, consider using [method _shortcut_input] instead.
|
|
[b]Note:[/b] This method is only called if the node is present in the scene tree (i.e. if it's not an orphan).

<method name="add_child">
|
|
<return type="void" />
|
|
<param index="0" name="node" type="Node" />
|
|
<param index="1" name="force_readable_name" type="bool" default="false" />
|
|
<param index="2" name="internal" type="int" enum="Node.InternalMode" default="0" />
|
|
<description>
|
|
Adds a child [param 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 [param force_readable_name] is [code]true[/code], improves the readability of the added [param node]. If not named, the [param node] is renamed to its type, and if it shares [member name] with a sibling, a number is suffixed more appropriately. This operation is very slow. As such, it is recommended leaving this to [code]false[/code], which assigns a dummy name featuring [code]@[/code] in both situations.
|
|
If [param internal] is different than [constant INTERNAL_MODE_DISABLED], the child will be added as internal node. Such nodes are ignored by methods like [method get_children], unless their parameter [code]include_internal[/code] is [code]true[/code]. The intended usage is to hide the internal nodes from the user, so the user won't accidentally delete or modify them. Used by some GUI nodes, e.g. [ColorPicker]. See [enum InternalMode] for available modes.
|
|
[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:
|
|
[codeblocks]
|
|
[gdscript]
|
|
var child_node = get_child(0)
|
|
if child_node.get_parent():
|
|
child_node.get_parent().remove_child(child_node)
|
|
add_child(child_node)
|
|
[/gdscript]
|
|
[csharp]
|
|
Node childNode = GetChild(0);
|
|
if (childNode.GetParent() != null)
|
|
{
|
|
childNode.GetParent().RemoveChild(childNode);
|
|
}
|
|
AddChild(childNode);
|
|
[/csharp]
|
|
[/codeblocks]
|
|
If you need the child node to be added below a specific node in the list of children, use [method add_sibling] 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=$DOCS_URL/tutorials/plugins/running_code_in_the_editor.html]tool scripts[/url] and [url=$DOCS_URL/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.
|
|

</method>
|
|
<method name="add_sibling">
|
|
<return type="void" />
|
|
<param index="0" name="sibling" type="Node" />
|
|
<param index="1" name="force_readable_name" type="bool" default="false" />
|
|
<description>
|
|
Adds a [param sibling] node to current's node parent, at the same level as that node, right below it.
|
|
If [param force_readable_name] is [code]true[/code], improves the readability of the added [param sibling]. If not named, the [param sibling] is renamed to its type, and if it shares [member name] with a sibling, a number is suffixed more appropriately. This operation is very slow. As such, it is recommended leaving this to [code]false[/code], which assigns a dummy name featuring [code]@[/code] in both situations.
|
|
Use [method add_child] instead of this method if you don't need the child node to be added below a specific node in the list of children.
|
|
[b]Note:[/b] If this node is internal, the new sibling will be internal too (see [code]internal[/code] parameter in [method add_child]).

<method name="add_to_group">
|
|
<return type="void" />
|
|
<param index="0" name="group" type="StringName" />
|
|
<param index="1" name="persistent" type="bool" default="false" />
|
|
<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 [param persistent] option is used when packing node to [PackedScene] and saving to file. Non-persistent groups aren't stored.
|
|
[b]Note:[/b] For performance reasons, the order of node groups is [i]not[/i] guaranteed. The order of node groups should not be relied upon as it can vary across project runs.

<method name="call_deferred_thread_group" qualifiers="vararg">
|
|
<return type="Variant" />
|
|
<param index="0" name="method" type="StringName" />
|
|
<description>
|
|
This function is similar to [method Object.call_deferred] except that the call will take place when the node thread group is processed. If the node thread group processes in sub-threads, then the call will be done on that thread, right before [constant NOTIFICATION_PROCESS] or [constant NOTIFICATION_PHYSICS_PROCESS], the [method _process] or [method _physics_process] or their internal versions are called.
|

|
<return type="Variant" />
|

<param index="0" name="method" type="StringName" />
|
|
<description>
|
|
This function ensures that the calling of this function will succeed, no matter whether it's being done from a thread or not. If called from a thread that is not allowed to call the function, the call will become deferred. Otherwise, the call will go through directly.

<method name="can_process" qualifiers="const">
|
|
<return type="bool" />
|
|
<description>
|
|
Returns [code]true[/code] if the node can process while the scene tree is paused (see [member process_mode]). Always returns [code]true[/code] if the scene tree is not paused, and [code]false[/code] if the node is not in the tree.

<method name="create_tween">
|
|
<return type="Tween" />
|
|
<description>
|
|
Creates a new [Tween] and binds it to this node. This is equivalent of doing:
|
|
[codeblocks]
|
|
[gdscript]
|
|
get_tree().create_tween().bind_node(self)
|
|
[/gdscript]
|
|
[csharp]
|
|
GetTree().CreateTween().BindNode(this);
|
|
[/csharp]
|
|
[/codeblocks]
|
|
The Tween will start automatically on the next process frame or physics frame (depending on [enum Tween.TweenProcessMode]).
|

<method name="duplicate" qualifiers="const">
|
|
<return type="Node" />
|
|
<param index="0" name="flags" type="int" default="15" />
|
|
<description>
|
|
Duplicates the node, returning a new node.
|
|
You can fine-tune the behavior using the [param flags] (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.

<method name="find_child" qualifiers="const">

<param index="1" name="recursive" type="bool" default="true" />
|
|
<param index="2" name="owned" type="bool" default="true" />
|
|
<description>
|
|
Finds the first descendant of this node whose name matches [param pattern] as in [method String.match]. Internal children are also searched over (see [code]internal[/code] parameter in [method add_child]).
|
|
[param pattern] does not match against the full path, just against individual node names. It is case-sensitive, with [code]"*"[/code] matching zero or more characters and [code]"?"[/code] matching any single character except [code]"."[/code]).
|
|
If [param recursive] is [code]true[/code], all child nodes are included, even if deeply nested. Nodes are checked in tree order, so this node's first direct child is checked first, then its own direct children, etc., before moving to the second direct child, and so on. If [param recursive] is [code]false[/code], only this node's direct children are matched.
|
|
If [param owned] is [code]true[/code], this method only finds nodes who have an assigned [member Node.owner]. This is especially important for scenes instantiated through a script, because those scenes don't have an owner.
|
|
Returns [code]null[/code] if no matching [Node] is found.
|
|
[b]Note:[/b] As this method walks through all the descendants of the node, it is the slowest way to get a reference to another node. Whenever possible, consider using [method get_node] with unique names instead (see [member unique_name_in_owner]), or caching the node references into variable.
|
|
[b]Note:[/b] To find all descendant nodes matching a pattern or a class type, see [method find_children].

Finds descendants of this node whose name matches [param pattern] as in [method String.match], and/or type matches [param type] as in [method Object.is_class]. Internal children are also searched over (see [code]internal[/code] parameter in [method add_child]).
|
|
[param pattern] does not match against the full path, just against individual node names. It is case-sensitive, with [code]"*"[/code] matching zero or more characters and [code]"?"[/code] matching any single character except [code]"."[/code]).
|
|
[param type] will check equality or inheritance, and is case-sensitive. [code]"Object"[/code] will match a node whose type is [code]"Node"[/code] but not the other way around.
|
|
If [param recursive] is [code]true[/code], all child nodes are included, even if deeply nested. Nodes are checked in tree order, so this node's first direct child is checked first, then its own direct children, etc., before moving to the second direct child, and so on. If [param recursive] is [code]false[/code], only this node's direct children are matched.
|
|
If [param owned] is [code]true[/code], this method only finds nodes who have an assigned [member Node.owner]. This is especially important for scenes instantiated through a script, because those scenes don't have an owner.
|
|
Returns an empty array if no matching nodes are found.
|
|
[b]Note:[/b] As this method walks through all the descendants of the node, it is the slowest way to get references to other nodes. Whenever possible, consider caching the node references into variables.
|

[b]Note:[/b] As this method walks upwards in the scene tree, it can be slow in large, deeply nested scene trees. Whenever possible, consider using [method get_node] with unique names instead (see [member unique_name_in_owner]), or caching the node references into variable.

Returns a child node by its index (see [method get_child_count]). This method is often used for iterating all children of a node.
|
|
Negative indices access the children from the last one.
|
|
If [param include_internal] is [code]false[/code], internal children are skipped (see [code]internal[/code] parameter in [method add_child]).
|
|
To access a child node via its name, use [method get_node].

Returns an array listing the groups that the node is a member of.
|
|
[b]Note:[/b] For performance reasons, the order of node groups is [i]not[/i] guaranteed. The order of node groups should not be relied upon as it can vary across project runs.
|
|
[b]Note:[/b] The engine uses some group names internally (all starting with an underscore). To avoid conflicts with internal groups, do not add custom groups whose name starts with an underscore. To exclude internal groups while looping over [method get_groups], use the following snippet:
|
|
[codeblocks]
|
|
[gdscript]
|
|
# Stores the node's non-internal groups only (as an array of Strings).
|
|
var non_internal_groups = []
|

for group in get_groups():
|

non_internal_groups.push_back(group)

Returns the node's order in the scene tree branch. For example, if called on the first child node the position is [code]0[/code].
|
|
If [param include_internal] is [code]false[/code], the index won't take internal children into account, i.e. first non-internal child will have index of 0 (see [code]internal[/code] parameter in [method add_child]).

<return type="Node" />

<param index="0" name="path" type="NodePath" />
|
|
<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, [code]null[/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:
|
|
[codeblocks]
|
|
[gdscript]
|
|
get_node("Sword")
|
|
get_node("Backpack/Dagger")
|
|
get_node("../Swamp/Alligator")
|
|
get_node("/root/MyGame")
|
|
[/gdscript]
|
|
[csharp]
|
|
GetNode("Sword");
|
|
GetNode("Backpack/Dagger");
|
|
GetNode("../Swamp/Alligator");
|

<method name="get_node_and_resource">
|
|
<return type="Array" />
|
|
<param 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:
|
|
[codeblocks]
|
|
[gdscript]
|
|
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]
|
|
[/gdscript]
|
|
[csharp]
|
|
GD.Print(GetNodeAndResource("Area2D/CollisionShape2D")); // [[CollisionShape2D:1161], Null, ]
|
|
GD.Print(GetNodeAndResource("Area2D/CollisionShape2D:shape")); // [[CollisionShape2D:1161], [RectangleShape2D:1156], ]
|
|
GD.Print(GetNodeAndResource("Area2D/CollisionShape2D:shape:extents")); // [[CollisionShape2D:1161], [RectangleShape2D:1156], :extents]

Returns the relative [NodePath] from this node to the specified [param node]. Both nodes must be in the same scene or the function will fail.
|
|
If [param use_unique_path] is [code]true[/code], returns the shortest path considering unique node.
|
|
[b]Note:[/b] If you get a relative path which starts from a unique node, the path may be longer than a normal relative path due to the addition of the unique node's name.

Queues a node for deletion at the end of the current frame. When deleted, all of its child nodes will be deleted as well, and all references to the node and its children will become invalid, see [method Object.free].
|
|
It is safe to call [method queue_free] multiple times per frame on a node, and to [method Object.free] a node that is currently queued for deletion. Use [method Object.is_queued_for_deletion] to check whether a node will be deleted at the end of the frame.
|
|
The node will only be freed after all other deferred calls are finished, so using [method queue_free] is not always the same as calling [method Object.free] through [method Object.call_deferred].

Sends a remote procedure call request for the given [param method] 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. Behavior depends on the RPC configuration for the given method, see [method rpc_config] and [annotation @GDScript.@rpc]. Methods are not exposed to RPCs by default. Returns [code]null[/code].
|
|
[b]Note:[/b] You can only safely use RPCs on clients after you received the [code]connected_to_server[/code] signal from the [MultiplayerAPI]. You also need to keep track of the connection state, either by the [MultiplayerAPI] signals like [code]server_disconnected[/code] or by checking [code]get_multiplayer().peer.get_connection_status() == CONNECTION_CONNECTED[/code].

Sets the node's multiplayer authority to the peer with the given peer ID. The multiplayer authority is the peer that has authority over the node on the network. Useful in conjunction with [method rpc_config] and the [MultiplayerAPI]. Defaults to peer ID 1 (the server). If [param recursive], the given peer is recursively set as the authority for all children of this node.
|

[b]Warning:[/b] This does [b]not[/b] automatically replicate the new authority to other peers. It is developer's responsibility to do so. You can propagate the information about the new authority using [member MultiplayerSpawner.spawn_function], an RPC, or using a [MultiplayerSynchronizer]. Also, the parent's authority does [b]not[/b] propagate to newly added children.

|
|
<member name="owner" type="Node" setter="set_owner" getter="get_owner">
|
|
The node owner. A node can have any ancestor node as owner (i.e. a parent, grandparent, etc. node ascending in the tree). This implies that [method add_child] should be called before setting the owner, so that this relationship of parenting exists. When saving a node (using [PackedScene]), all the nodes it owns will be saved with it. This allows for the creation of complex scene trees, with instancing and subinstancing.
|
|
[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=$DOCS_URL/tutorials/plugins/running_code_in_the_editor.html]tool scripts[/url] and [url=$DOCS_URL/tutorials/plugins/editor/index.html]editor plugins[/url]. If a new node is added to the tree without setting its owner as an ancestor in that tree, it will be visible in the 2D/3D view, but not in the scene tree (and not persisted when packing or saving).

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.

|
|
<member name="process_thread_group" type="int" setter="set_process_thread_group" getter="get_process_thread_group" enum="Node.ProcessThreadGroup" default="0">
|
|
Set the process thread group for this node (basically, whether it receives [constant NOTIFICATION_PROCESS], [constant NOTIFICATION_PHYSICS_PROCESS], [method _process] or [method _physics_process] (and the internal versions) on the main thread or in a sub-thread.
|
|
By default, the thread group is [constant PROCESS_THREAD_GROUP_INHERIT], which means that this node belongs to the same thread group as the parent node. The thread groups means that nodes in a specific thread group will process together, separate to other thread groups (depending on [member process_thread_group_order]). If the value is set is [constant PROCESS_THREAD_GROUP_SUB_THREAD], this thread group will occur on a sub thread (not the main thread), otherwise if set to [constant PROCESS_THREAD_GROUP_MAIN_THREAD] it will process on the main thread. If there is not a parent or grandparent node set to something other than inherit, the node will belong to the [i]default thread group[/i]. This default group will process on the main thread and its group order is 0.
|
|
During processing in a sub-thread, accessing most functions in nodes outside the thread group is forbidden (and it will result in an error in debug mode). Use [method Object.call_deferred], [method call_thread_safe], [method call_deferred_thread_group] and the likes in order to communicate from the thread groups to the main thread (or to other thread groups).
|
|
To better understand process thread groups, the idea is that any node set to any other value than [constant PROCESS_THREAD_GROUP_INHERIT] will include any children (and grandchildren) nodes set to inherit into its process thread group. this means that the processing of all the nodes in the group will happen together, at the same time as the node including them.

<member name="process_thread_group_order" type="int" setter="set_process_thread_group_order" getter="get_process_thread_group_order">

<member name="scene_file_path" type="String" setter="set_scene_file_path" getter="get_scene_file_path">

If a scene is instantiated from a file, its topmost node contains the absolute file path from which it was loaded in [member scene_file_path] (e.g. [code]res://levels/1.tscn[/code]). Otherwise, [member scene_file_path] is set to an empty string.
