• void connect_node ( String input_node, int input_index, String output_node )

Connects the output of an AnimationNode as input for another AnimationNode, at the input port specified by input_index.

• void disconnect_node ( String input_node, int input_index )

Disconnects the node connected to the specified input.

• AnimationNode get_node ( String name ) const

Returns the sub-node with the specified name.

• Vector2 get_node_position ( String name ) const

Returns the position of the sub-node with the specified name.

• bool has_node ( String name ) const

Returns true if a sub-node with specified name exists.

• void remove_node ( String name )

Removes a sub-node.

• void rename_node ( String name, String new_name )

Changes the name of a sub-node.

• void set_node_position ( String name, Vector2 position )
