Hello all…
What I want is a code in (C # or GDscript) to make the player move the same way as the yellow ball … Watch the video (https://youtu.be/swWtPulkuMw)
more clarification:
I want the player to move every time (dragging the phone screen or with the keyboard buttons) a continuous movement towards dragging or scrolling (up or down right or left) until it hits a wall or any other obstacle so I can move it again … It is a puzzle game
thank you all .

the movement could be done using acceleration and deceleration . the continuous movement , you could restrict accepting Input to the condition “if velocity.length() == 0:” accept Input . an area or RayCast could be used to signal the ball to decelerate to a stop shy of the wall.

like this:

func get_input():
velocity = Vector2()
if Input.is_action_pressed("ui_left"):
	velocity.x -= 1
if Input.is_action_pressed("ui_right"):
	velocity.x += 1
if Input.is_action_pressed("ui_up"):
	velocity.y -= 1
if Input.is_action_pressed("ui_down"):
	velocity.y += 1
if velocity.length() == 0:
	velocity = velocity.normalized() * speed

shy on time right now but no , it would look more like this.

func get_input():
   if velocity.length() == 0:
      velocity = Vector2.ZERO
      if Input.is_action_pressed("right"): # rest of your input script

velocity cant be zero till after the length test because that is asking if the player has velocity.

extends KinematicBody2D


var velocity = Vector2.ZERO
var direction = Vector2.ZERO
var speed = 400

func get_input():
	direction = Vector2.ZERO
	if Input.is_action_pressed("ui_left"):
		direction.x -= 1
	if Input.is_action_pressed("ui_right"):
		direction.x += 1

func _physics_process(_delta):
	if velocity.length() == 0:
		get_input()
	velocity = Vector2.ZERO
	velocity += direction * speed
	velocity = move_and_slide (velocity)

Thank you very much it works great
