How to make the Attack animation not write over the idle

Question

My Idle seems to override my Attack so it only plays the first frame this is my code

extends KinematicBody2D

var statemachine
var runspeed = 200
var attacks = ["attack1", "attack2"]
var velocity = Vector2.ZERO
var is_attacking

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

func attack():
isattacking = state_machine.travel("attack")

func getinput():
var current = statemachine.getcurrentnode()
velocity = Vector2.ZERO
if Input.isactionjustpressed("attack"):
statemachine.travel("attack")
return
isattacking = true
if Input.isactionpressed("jump"):
statemachine.travel("Jump")
if Input.isactionpressed("left"):
velocity.x -= 1
statemachine.travel("Run")
$Sprite.scale.x = -1
if Input.isactionpressed("right"):
velocity.x += 1
statemachine.travel("Run")
$Sprite.scale.x = 1
if velocity.length() == 0:
state_machine.travel("Idle")

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

Comments

Use an actionjustpressed for the attack
and for the animation to play, use another code the same but with actionpressed
What happens is that when you call actionjustpressed, what you do is that only when you press atak, only that instant is reproduced.
and actionpressed is so that if the key is held pressed, it will play the animation if the key is pressed
basically just pressed lasts a frame and pressed lasts until the key is released

I hope it helps you since I do not speak English and it is difficult for me to fully understand your question grettings!
