Brief Description

State machine for control of animations.

Methods

Description

Contains multiple nodes representing animation states, connected in a graph. Nodes 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 programatically. Example:

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

Method Descriptions

• void add_node ( String 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 ( String from, String to, AnimationNodeStateMachineTransition transition )

Adds a transition between the given nodes.

• String get_end_node ( ) const

Returns the graph’s end node.

• Vector2 get_graph_offset ( ) const

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

• AnimationNode get_node ( String name ) const

Returns the animation node with the given name.

• String get_node_name ( AnimationNode node ) const

Returns the given animation node’s name.

• Vector2 get_node_position ( String name ) const

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

• String get_start_node ( ) const

Returns the graph’s end node.

• AnimationNodeStateMachineTransition get_transition ( int idx ) const

Returns the given transition.

• int get_transition_count ( ) const

Returns the number of connections in the graph.

• String get_transition_from ( int idx ) const

Returns the given transition’s start node.

• String get_transition_to ( int idx ) const

Returns the given transition’s end node.

• bool has_node ( String name ) const

Returns true if the graph contains the given node.

• bool has_transition ( String from, String to ) const

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

• void remove_node ( String name )

Deletes the given node from the graph.

• void remove_transition ( String from, String to )

Deletes the given transition.

• void remove_transition_by_index ( int idx )

Deletes the given transition.

• void rename_node ( String name, String new_name )

Renames the given node.

• void set_end_node ( String name )

Sets the given node as the graph end point.

• void set_graph_offset ( Vector2 offset )

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

• void set_node_position ( String name, Vector2 position )

Sets the node’s coordinates. Used for display in the editor.

• void set_start_node ( String name )

Sets the given node as the graph start point.
