Signal Descriptions

line_created(line: YggdrasilConnection, from_node_id: int, to_node_id: int)

Emitted when a connection line is created.

line_disconnected(from_node: YggdrasilNodeButton, to_node: YggdrasilNodeButton)

Emitted when an existing connection between two nodes is removed.

node_connected(from_node: YggdrasilNodeButton, to_node_id: int)

Emitted when a node is connected to another node.

node_disconnected(from_node: YggdrasilNodeButton, to_node_id: int)

Emitted when a node is disconnected from another node.

Method Descriptions

void load_tree(tree_data: YggdrasilTree)

Loads all stored node connections from tree_data, instantiates their line nodes, applies line data, adds them to the lines container, updates visibility based on tree reveal state, and emits connection signals.

void create_connection(from_node: YggdrasilNodeButton, to_node: YggdrasilNodeButton)

Creates a connection between from_node and to_node. If the connection already exists, removes it instead and emits disconnection signals.

PackedVector2Array _bezier_points(segments: int, p0: Vector2, p1: Vector2, p2: Vector2)

Returns a sampled quadratic Bézier curve point array between p0 and p2 using p1 as the control point.

PackedVector2Array _arc_points(segments: int, center: Vector2, reversed: bool)

Returns a sampled arc point array around center using the specified segment count and direction.

void update_connected_lines(node: YggdrasilNodeButton)

Rebuilds the geometry of all incoming and outgoing lines connected to node.

Vector2 _get_center_position(node: Control)

Returns the center position of node based on its position and size.

void on_node_allocation_changed(node: YggdrasilNodeButton)

Refreshes the visual state of lines connected to node after its allocation state changes.
