Question

Can someone pls help me and fix this code! I tried using AI but they messed up my movement, and it also would not work to change my mouse mode while I press ESC
here is my script:

extends CharacterBody3D

@export var playerSpeeed = 5.0
@export var jumpForce = 10.0
@export var gravity = 8.0
@export var mouseSensivity = 0.5

@onready var head = $Head
@onready var camera = $Head/Camera3D

var direction = Vector3.ZERO
var camera_x_angel = 0.0

func _ready():
Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _Input(event):
if event is InputEventMouseMotion:
head.rotate_y(-deg_to_rad(event.relative.x * mouseSensivity))

	camera_x_angel += event.relative.y * mouseSensivity
	camera_x_angel = clamp(camera_x_angel, -90.0, 90.0)
	camera.rotation.x = -deg_to_rad(camera_x_angel)
	
elif event is InputEventKey:
	if Input.is_key_pressed(KEY_ESCAPE):
		Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)

func _process(delta):
direction = Input.get_axis(“left”, “right”) * head.basis.x + Input.get_axis(“forward”, “backward”) * head.basis.z
velocity = direction.normalized() * playerSpeeed + velocity.y * Vector3.UP

if Input.is_action_just_pressed("jump") and is_on_floor():
	velocity.y += jumpForce
else:
	velocity.y -= gravity * delta

move_and_slide()

Can you tell us what the problem is?

What do you expect to happen vs. what actually happens?

I want to have fps movement, and that works. but I have an camera on the node “Head” but it doesnt move around with the cursor. and i want that the camera rotates with the cursor so i can look around. :cry:

@tibaverus can you pls help. My life is ending on this problem

I wouldn’t try to vibecode a basic concept like this. Have you watched a tutorial yet? https://www.youtube.com/watch?v=A3HLeyaBCq4

The input function seems good, other than the mis-capitalized name, you may notice the function is missing it’s blue arrow by the line number; this is the correct signature:

func _input(event: InputEvent) -> void:

Your move_and_slide should only happen during physics, so change _process to _physics_process.

The direction could be massively simplified with Input.get_vector and using basis which I assume you were trying to do but the forward/right vectors don’t rotate like the basis does on it’s own.

func _physics_process(delta: float) -> void:
	var input_direction: Vector2 = Input.get_vector("left", "right", "forward", "backward")
	var direction: Vector3 = head.basis * Vector3(input_direction.x, 0, input_direction.y)

	# you should use a seperate horizontal/vertical velocity so you can preserve gravity
	var vertical_velocity := velocity.project(up_direction)
	var horizontal_velocity := velocity - vertical_velocity

	# assign player movement on a horizontal plane, not overwriting gravity
	horizontal_velocity = direction * playerSpeeed

	# gravity and jumping, using vertical_velocity
	if Input.is_action_just_pressed("jump") and is_on_floor():
		vertical_velocity.y += jumpForce
	else:
		vertical_velocity.y -= gravity * delta

	# re-combine horizontal and vertical velocity
	velocity = vertical_velocity + horizontal_velocity
	move_and_slide()

Make sure to paste code with proper formatting between three ticks ```

I think this is the right way but that I used it wrong. the camera rotation still is not working can you check my new code?

extends CharacterBody3D

@export var playerSpeeed = 5.0
@export var jumpForce = 10.0
@export var gravity = 8.0
@export var mouseSensivity = 0.5

@onready var head = $Head
@onready var camera = $Head/Camera3D

var direction = Vector3.ZERO
var camera_x_angel = 0.0

func _ready():
Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _Input(event: InputEvent) → void:
if event is InputEventMouseMotion:
head.rotate_y(-deg_to_rad(event.relative.x * mouseSensivity))

camera_x_angel += event.relative.y * mouseSensivity
camera_x_angel = clamp(camera_x_angel, -90.0, 90.0)
camera.rotation.x = -deg_to_rad(camera_x_angel)

func _input(event):
if event is InputEventKey:
if event.scancode == KEY_ESCAPE and event.pressed:
Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)

func _process(delta):
direction = Input.get_axis(“left”, “right”) * head.basis.x + Input.get_axis(“forward”, “backward”) * head.basis.z
velocity = direction.normalized() * playerSpeeed + velocity.y * Vector3.UP

func _physics_process(delta: float) → void:
var input_direction: Vector2 = Input.get_vector(“left”, “right”, “forward”, “backward”)
var direction: Vector3 = head.basis * Vector3(input_direction.x, 0, input_direction.y)

# you should use a seperate horizontal/vertical velocity so you can preserve gravity
var vertical_velocity := velocity.project(up_direction)
var horizontal_velocity := velocity - vertical_velocity

# assign player movement on a horizontal plane, not overwriting gravity
horizontal_velocity = direction * playerSpeeed

# gravity and jumping, using vertical_velocity
if Input.is_action_just_pressed("jump") and is_on_floor():
	vertical_velocity.y += jumpForce
else:
	vertical_velocity.y -= gravity * delta

# re-combine horizontal and vertical velocity
velocity = vertical_velocity + horizontal_velocity
move_and_slide()

I used a tutorial for this code, but i think i did something wrong because it didnt work

you should only have one func _input, the capitalized version is not an override so it does nothing, unlike the lower case _input which is correctly named.

Thank you so much! your a life saver! but I have another problem in the same project now… I’m not forcing you, but on my other topic is the new problem (Realy thank you fot fixing the camera!)
