  Emitted when a child node enters the scene tree, either because it entered on its own or because this node entered with it.

• var childExitingTree: Signal2

  Emitted when a child node is about to exit the scene tree, either because it is being removed or freed directly, or because this node is exiting the tree.

• var childOrderChanged: SimpleSignal

  Emitted when the list of children is changed. This happens when child nodes are added, moved or removed.

• var editorDescription: String

  Add a custom description to a node. It will be displayed in a tooltip when hovered in editor’s scene tree.

• var multiplayer: MultiplayerAPI?

  The MultiplayerAPI instance associated with this node. See getMultiplayer(forPath:).

• var name: StringName

  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.

• var owner: Node?

  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 addChild(node:forceReadableName:`internal`:) 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.

• var processMode: Node.ProcessMode

  Can be used to pause or unpause the node, or make the node paused based on the SceneTree, or make it inherit the process mode from its parent (default).

• var processPhysicsPriority: Int32

  Similar to processPriority but for notificationPhysicsProcess, _physicsProcess(delta:) or the internal version.

• var processPriority: Int32

  The node’s priority in the execution order of the enabled processing callbacks (i.e. notificationProcess, notificationPhysicsProcess and their internal counterparts). Nodes whose process priority value is lower will have their processing callbacks executed first.

• var processThreadGroup: Node.ProcessThreadGroup

  Set the process thread group for this node (basically, whether it receives notificationProcess, notificationPhysicsProcess, _process(delta:) or _physicsProcess(delta:) (and the internal versions) on the main thread or in a sub-thread.

• var processThreadGroupOrder: Int32

  Change the process thread group order. Groups with a lesser order will process before groups with a greater order. This is useful when a large amount of nodes process in sub thread and, afterwards, another group wants to collect their result in the main thread, as an example.

• var processThreadMessages: Node.ProcessThreadMessages

  Set whether the current thread group will process messages (calls to callDeferredThreadGroup(method:) on threads, and whether it wants to receive them during regular process or physics process callbacks.

• var ready: SimpleSignal

  Emitted when the node is ready. Comes after _ready callback and follows the same rules.

• var renamed: SimpleSignal

  Emitted when the node is renamed.

• var replacingBy: Signal3

  Emitted when this node is being replaced by the node, see replaceBy(node:keepGroups:).

• var sceneFilePath: String

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

• var treeEntered: SimpleSignal

  Emitted when the node enters the tree.

• var treeExited: SimpleSignal

  Emitted after the node exits the tree and is no longer active.

• var treeExiting: SimpleSignal

  Emitted when the node is still active but about to exit the tree. This is the right place for de-initialization (or a “destructor”, if you will).

• var uniqueNameInOwner: Bool

  Sets this node’s name as a unique name in its owner. This allows the node to be accessed as %Name instead of the full path, from any node within that scene.

• func addChild(node: Node?, forceReadableName: Bool, internal: Node.InternalMode)

  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.

• func addSibling(Node?, forceReadableName: Bool)

  Adds a sibling node to current’s node parent, at the same level as that node, right below it.

• func addToGroup(StringName, persistent: Bool)

  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 isInsideTree). See notes in the description, and the group methods in SceneTree.

• func callDeferredThreadGroup(method: StringName, Variant...) -> Variant

  This function is similar to Object/callDeferred(method:) 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 notificationProcess or notificationPhysicsProcess, the _process(delta:) or _physicsProcess(delta:) or their internal versions are called.

• func callThreadSafe(method: StringName, Variant...) -> Variant

  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.

• func canProcess() -> Bool

  Returns true if the node can process while the scene tree is paused (see processMode). Always returns true if the scene tree is not paused, and false if the node is not in the tree.

• func createTween() -> Tween?

  Creates a new Tween and binds it to this node. This is equivalent of doing:

• func duplicate(flags: Int32) -> Node?

  Duplicates the node, returning a new node.

• func findChild(pattern: String, recursive: Bool, owned: Bool) -> Node?

• func findChildren(pattern: String, type: String, recursive: Bool, owned: Bool) -> ObjectCollection<Node>

  Finds descendants of this node whose name matches pattern as in String/match(expr:), and/or type matches type as in isClass(_:). Internal children are also searched over (see internal parameter in addChild(node:forceReadableName:`internal`:)).

• func findParent(pattern: String) -> Node?

  Finds the first parent of the current node whose name matches pattern as in String/match(expr:).

• func getChild(idx: Int32, includeInternal: Bool) -> Node?

• func getMultiplayerAuthority() -> Int32

  Returns the peer ID of the multiplayer authority for this node. See setMultiplayerAuthority(id:recursive:).

• func getNode(path: NodePath) -> Node?

  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, null is returned and an error is logged. Attempts to access methods on the return value will result in an “Attempt to call on a null instance.” error.

• func getNodeAndResource(path: NodePath) -> GArray

  Fetches a node and one of its resources as specified by the NodePath’s subname (e.g. Area2D/CollisionShape2D:shape). If several nested resources are specified in the NodePath, the last one will be fetched.

• func getNodeOrNull(path: NodePath) -> Node?

  Similar to getNode(path:), but does not log an error if path does not point to a valid Node.

• func getParent() -> Node?

  Returns the parent node of the current node, or null if the node lacks a parent.

• func getPath() -> NodePath

  Returns the absolute path of the current node. This only works if the current node is inside the scene tree (see isInsideTree).

• func getPathTo(node: Node?, useUniquePath: Bool) -> NodePath

  Returns the relative NodePath from this node to the specified node. Both nodes must be in the same scene or the function will fail.

• func getPhysicsProcessDeltaTime() -> Double

  Returns the time elapsed (in seconds) since the last physics-bound frame (see _physicsProcess(delta:)). This is always a constant value in physics processing unless the frames per second is changed via physicsTicksPerSecond.

• func getProcessDeltaTime() -> Double

  Returns the time elapsed (in seconds) since the last process callback. This value may vary from frame to frame.

• func getSceneInstanceLoadPlaceholder() -> Bool

  Returns true if this is an instance load placeholder. See InstancePlaceholder.

• func getTree() -> SceneTree?

  Returns the SceneTree that contains this node. Returns null and prints an error if this node is not inside the scene tree. See also isInsideTree.

• func getTreeString() -> String

  Returns the tree as a String. Used mainly for debugging purposes. This version displays the path relative to the current node, and is good for copy/pasting into the getNode(path:) function. It also can be used in game UI/UX.

• func getTreeStringPretty() -> String

  Similar to getTreeString, this returns the tree as a String. This version displays a more graphical representation similar to what is displayed in the Scene Dock. It is useful for inspecting larger trees.

• func getViewport() -> Viewport?

  Returns the node’s Viewport.

• func getWindow() -> Window?

  Returns the Window that contains this node. If the node is in the main window, this is equivalent to getting the root node (get_tree().get_root()).

  Returns true if the node that the NodePath points to exists.

• func hasNodeAndResource(path: NodePath) -> Bool

  Returns true if the NodePath points to a valid node and its subname points to a valid resource, e.g. Area2D/CollisionShape2D:shape. Properties with a non-Resource type (e.g. nodes or primitive math types) are not considered resources.

  Returns true if the node is processing unhandled key input (see setProcessUnhandledKeyInput(enable:)).

• func moveChild(childNode: Node?, toIndex: Int32)

  Moves a child node to a different index (order) among the other children. Since calls, signals, etc. are performed by tree order, changing the order of children nodes may be useful. If toIndex is negative, the index will be counted from the end.

• func notifyDeferredThreadGroup(what: Int32)

  Similar to callDeferredThreadGroup(method:), but for notifications.

• func notifyThreadSafe(what: Int32)

  Similar to callThreadSafe(method:), but for notifications.

• func printTree()

  Prints the tree to stdout. Used mainly for debugging purposes. This version displays the path relative to the current node, and is good for copy/pasting into the getNode(path:) function.

• func printTreePretty()

  Similar to printTree, this prints the tree to stdout. This version displays a more graphical representation similar to what is displayed in the Scene Dock. It is useful for inspecting larger trees.

• func propagateCall(method: StringName, args: GArray, parentFirst: Bool)

  Calls the given method (if present) with the arguments given in args on this node and recursively on all its children. If the parentFirst argument is true, the method will be called on the current node first, then on all its children. If parentFirst is false, the children will be called first.

• func propagateNotification(what: Int32)

  Notifies the current node and all its children recursively by calling notification(what:reversed:) on all of them.

• func queueFree()

  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 Object/free().

• func removeChild(node: Node?)

  Removes a child node. The node is NOT deleted and must be deleted manually.

• func removeFromGroup(StringName)

  Removes a node from the group. Does nothing if the node is not in the group. See notes in the description, and the group methods in SceneTree.

• func replaceBy(node: Node?, keepGroups: Bool)

  Replaces a node in a scene by the given one. Subscriptions that pass through this node will be lost.

• func requestReady()

  Requests that _ready be called again. Note that the method won’t be called immediately, but is scheduled for when the node is added to the scene tree again. _ready is called only for the node which requested it, which means that you need to request ready for each child if you want them to call _ready too (in which case, _ready will be called in the same order as it would normally).

• func rpc(method: StringName, Variant...) -> GodotError

  Sends a remote procedure call request for the given 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 rpcConfig(method:config:) and [annotation @GDScript.@rpc]. Methods are not exposed to RPCs by default. Returns null.

• func rpcConfig(method: StringName, config: Variant)

  Changes the RPC mode for the given method with the given config which should be null (to disable) or a GDictionary in the form:

• func rpcId(peerId: Int64, method: StringName, Variant...) -> GodotError

  Sends a rpc(method:) to a specific peer identified by peerId (see setTargetPeer(id:)). Returns null.

• func setDeferredThreadGroup(property: StringName, value: Variant)

  Similar to callDeferredThreadGroup(method:), but for setting properties.

  Sets the editable children state of node relative to this node. This method is only intended for use with editor tooling.

• func setMultiplayerAuthority(id: Int32, recursive: Bool)

  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 rpcConfig(method:config:) and the MultiplayerAPI. Defaults to peer ID 1 (the server). If recursive, the given peer is recursively set as the authority for all children of this node.

• func setPhysicsProcess(enable: Bool)

  Enables or disables physics (i.e. fixed framerate) processing. When a node is being processed, it will receive a notificationPhysicsProcess at a fixed (usually 60 FPS, see physicsTicksPerSecond to change) interval (and the _physicsProcess(delta:) callback will be called if exists). Enabled automatically if _physicsProcess(delta:) is overridden. Any calls to this before _ready will be ignored.

• func setPhysicsProcessInternal(enable: Bool)

  Enables or disables internal physics for this node. Internal physics processing happens in isolation from the normal _physicsProcess(delta:) calls and is used by some nodes internally to guarantee proper functioning even if the node is paused or physics processing is disabled for scripting (setPhysicsProcess(enable:)). Only useful for advanced uses to manipulate built-in nodes’ behavior.

• func setProcess(enable: Bool)

  Enables or disables processing. When a node is being processed, it will receive a notificationProcess on every drawn frame (and the _process(delta:) callback will be called if exists). Enabled automatically if _process(delta:) is overridden. Any calls to this before _ready will be ignored.

• func setProcessInput(enable: Bool)

  Enables or disables input processing. This is not required for GUI controls! Enabled automatically if _input(event:) is overridden. Any calls to this before _ready will be ignored.

• func setProcessInternal(enable: Bool)

  Enables or disabled internal processing for this node. Internal processing happens in isolation from the normal _process(delta:) calls and is used by some nodes internally to guarantee proper functioning even if the node is paused or processing is disabled for scripting (setProcess(enable:)). Only useful for advanced uses to manipulate built-in nodes’ behavior.

• func setProcessShortcutInput(enable: Bool)

  Enables shortcut processing. Enabled automatically if _shortcutInput(event:) is overridden. Any calls to this before _ready will be ignored.

• func setProcessUnhandledInput(enable: Bool)

  Enables unhandled input processing. This is not required for GUI controls! It enables the node to receive all input that was not previously handled (usually by a Control). Enabled automatically if _unhandledInput(event:) is overridden. Any calls to this before _ready will be ignored.

• func setProcessUnhandledKeyInput(enable: Bool)

  Enables unhandled key input processing. Enabled automatically if _unhandledKeyInput(event:) is overridden. Any calls to this before _ready will be ignored.

• func setSceneInstanceLoadPlaceholder(Bool)

  Sets whether this is an instance load placeholder. See InstancePlaceholder.

• func setThreadSafe(property: StringName, value: Variant)

  Similar to callThreadSafe(method:), but for setting properties.
