Why are'nt my Animation Playing

Question

extends KinematicBody2D

export (int) var speed = 200

var velocity = Vector2.ZERO
var state_machine

func ready():
statemachine = $AnimationTree.get("parameters/playback")

func getinput():
var current = statemachine.getcurrentnode()
velocity = Vector2.ZERO
if Input.isactionpressed("right"):
velocity.x += 1
statemachine.travel("RunRight")
if Input.isactionpressed("left"):
velocity.x -= 1
statemachine.travel("RunLeft")
if Input.isactionpressed("up"):
velocity.y -= 1
statemachine.travel("RunUp")
if Input.isactionpressed("down"):
velocity.y += 1
statemachine.travel("RunDown")
if velocity.length() == 0:
state_machine.travel("IdleDown")

func physicsprocess(delta):
getinput()
velocity = velocity.normalized() * speed
velocity = moveand_slide(velocity)

Few tips:
You can format your code in the question by selecting it and pressing the { } button above the text editor. This way others won't have problem reading it and you'll get the answer faster.
Also it's better to specify an exact version instead of "latest", since latest could mean latest stable release, in development build or something else entirely - also if somebody has the same question few years from now, they'll have even harder time pinpointing if the answer is suitable for their version of godot.

Answer 1

This could possibly be the issue, from the docs:

The state machine must be running before you can travel. Make sure to either call start() or choose a node to Autoplay on Load.
