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 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.

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. @@ -25,7 +25,7 @@ </return> <description> Called when the node enters the [SceneTree] (e.g. upon instancing, scene changing, or after calling [method add_child] in a script).
