AnimationNodeStateMachine¶

Inherits: AnimationRootNode < AnimationNode < Resource < RefCounted < Object

A state machine with multiple AnimationRootNodes, used by AnimationTree.

Description¶

Contains multiple AnimationRootNodes representing animation states, connected in a graph. Node transitions can be configured to happen automatically or via code, using a shortest-path algorithm. Retrieve the AnimationNodeStateMachinePlayback object from the AnimationTree node to control it programmatically.

Example:

var state_machine = $AnimationTree.get("parameters/playback")
state_machine.travel("some_state")

var stateMachine = GetNode<AnimationTree>("AnimationTree").Get("parameters/playback") as AnimationNodeStateMachinePlayback;
stateMachine.Travel("some_state");

Property Descriptions¶

bool allow_transition_to_self = false

void set_allow_transition_to_self ( bool value )
bool is_allow_transition_to_self ( )

If true, allows teleport to the self state with AnimationNodeStateMachinePlayback.travel. When the reset option is enabled in AnimationNodeStateMachinePlayback.travel, the animation is restarted. If false, nothing happens on the teleportation to the self state.

Method Descriptions¶

void add_node ( StringName name, AnimationNode node, Vector2 position=Vector2(0, 0) )

Adds a new node to the graph. The position is used for display in the editor.

void add_transition ( StringName from, StringName to, AnimationNodeStateMachineTransition transition )

Adds a transition between the given nodes.

Vector2 get_graph_offset ( ) const

Returns the draw offset of the graph. Used for display in the editor.

AnimationNode get_node ( StringName name ) const

Returns the animation node with the given name.

StringName get_node_name ( AnimationNode node ) const

Returns the given animation node's name.

Vector2 get_node_position ( StringName name ) const

Returns the given node's coordinates. Used for display in the editor.

AnimationNodeStateMachineTransition get_transition ( int idx ) const

Returns the given transition.

int get_transition_count ( ) const

Returns the number of connections in the graph.

StringName get_transition_from ( int idx ) const

Returns the given transition's start node.

StringName get_transition_to ( int idx ) const

Returns the given transition's end node.

bool has_node ( StringName name ) const

Returns true if the graph contains the given node.

bool has_transition ( StringName from, StringName to ) const

Returns true if there is a transition between the given nodes.

void remove_node ( StringName name )

Deletes the given node from the graph.

void remove_transition ( StringName from, StringName to )

Deletes the transition between the two specified nodes.

void remove_transition_by_index ( int idx )

Deletes the given transition by index.

void rename_node ( StringName name, StringName new_name )

Renames the given node.
