My character not moving

[Frostcatzz]

is something wrong with:
extends KinematicBody2D
const MAX_SPEED = 80
const ACCELERATION = 500
const FRICTION = 500

enum {
MOVE,
ROLL,
ATTACK
}

var velocity = Vector2.ZERO
var state = MOVE

onready var animationPlayer = $AnimationPlayer
onready var animationTree = $AnimationTree
onready var animationState = animationTree.get("parameters/playback")

func _ready():
animationTree.active = true

func _physics_process(delta):
match state:
MOVE:
move_state(delta)

	ROLL:
		pass
		
	ATTACK:
		attack_state(delta)
move_state(delta)

func move_state(delta):
var input_vector = Vector2.ZERO
input_vector.x = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left")
input_vector.y = Input.get_action_strength("ui_down") - Input.get_action_strength("ui_up")
input_vector = input_vector.normalized()

if input_vector != Vector2.ZERO:
	animationTree.set("parameters/idle/blend_position", input_vector)
	animationTree.set("parameters/Run/blend_position", input_vector)
	animationTree.set("parameters/Attack/blend_position", input_vector)
	animationState.travel("Run")
	velocity = velocity.move_toward(input_vector * MAX_SPEED, ACCELERATION * delta)
else:
	animationState.travel("idle")
	velocity = velocity.move_toward(Vector2.ZERO, FRICTION * delta)

velocity = move_and_slide(velocity)

if Input.is_action_just_pressed("attack"):
	state = ATTACK

func attack_state(delta):
animationState.travel("Attack")

did you end up fixing it?
