Overview

Contains multiple [graphics.gd/classdb/AnimationRootNode]s representing animation states, connected in a graph. State transitions can be configured to happen automatically or via code, using a shortest-path algorithm. Retrieve the graphics.gd/classdb/AnimationNodeStateMachinePlayback object from the graphics.gd/classdb/AnimationTree node to control it programmatically. 

package main

import (
	"graphics.gd/classdb/AnimationNodeStateMachinePlayback"
	"graphics.gd/classdb/AnimationTree"
	"graphics.gd/variant/Object"
)

func ExampleAnimationNodeStateMachine(tree AnimationTree.Instance) {
	var stateMachine = Object.Get(tree, "parameters/playback").(AnimationNodeStateMachinePlayback.Instance)
	stateMachine.Travel("some_state")
}

Types

type Advanced 

type Advanced = class

Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.

type Any 

type Any interface {
	gd.IsClass
	AsAnimationNodeStateMachine() Instance
}

type Expanded 

type Expanded [1]gdclass.AnimationNodeStateMachine

func (Expanded) AddNode 

func (self Expanded) AddNode(name string, node AnimationNode.Instance, position Vector2.XY)

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

type Extension 

type Extension[T gdclass.Interface] struct{ gdclass.Extension[T, Instance] }

Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension

func (*Extension[T]) AsAnimationNode 

func (self *Extension[T]) AsAnimationNode() AnimationNode.Instance

func (*Extension[T]) AsAnimationNodeStateMachine 

func (self *Extension[T]) AsAnimationNodeStateMachine() Instance

type ID 

type ID Object.ID

ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.

func (ID) Instance 

func (id ID) Instance() (Instance, bool)

type Instance 

type Instance [1]gdclass.AnimationNodeStateMachine

Instance of the class with convieniently typed arguments and results. 

var Nil Instance

Nil is a nil/null instance of the class. Equivalent to the zero value.
