move_and_slide, what i do?

Question

well, i dont know why but moveandslide are wrong, anyone can help me?

code:

extends Node2D

const UP = Vector2(0,-1)
const BOOST = 200
const GRAVITY = 10

var motion = Vector2()

func _ready():
pass # Replace with function body.

func physicsprocess(delta):
motion.y += GRAVITY

if Input.is_action_just_pressed("ui_accept"):
    motion.y =-BOOST

    motion = move_and_slide(motion,UP)

Answer 1

move_and_slide() is a method of KinematicBody2D. It does not work with Node2D, which your script extends.
