What code should be written for the movement of the sprite in CharacterBody2D if there is already written such code for the joystick:

Spamming "Please help me" over and over really isn't going to get many people to answer. I understand it was to get around the "this question is mostly code" flag, but you need to provide more details. What have you tried? It looks like the code is emitting a signal each frame that has input data. You most likely need to attach a script to your CharacterBody2D and listen for and respond to that signal. — Jack Kinsey, Jul 06 '23 at 19:34

You'll most likely want to move the CharacterBody2D itself, not the Sprite2D. To do this, the best way is probably in the physics process loop.

func _physics_process(delta):
    move_and_collide(direction * strength * delta)

This code does not work. I wrote the following code: but it doesn't work either – Вадим Jul 04 '23 at 17:45
