3D character body arrow keys not working after implementing capture the mouse

Help

Godot 4.3

Hello, I have been following allong on a 3RD person godot tutorial and I have implemented “Capture the mouse” but I now cannot use my arrow keys to walk around, I have changed the input map to my own buttons but the issue was present before doing that, I had the idea of removing the mouse code to see if that was the issue and it persisted so I am a bit confused on what to do from here, I would apreciate any help on solving this issue, here is my script:

extends CharacterBody3D

@onready var camera_mount: Node3D = $Camera_Mount

const SPEED = 5.0
const JUMP_VELOCITY = 4.5

@export var sens_horizontal = 0.5
@export var sens_vertical = 0.5

Get the gravity from the project settings to be synced with RigidBody nodes.

var gravity = ProjectSettings.get_setting(“physics/3d/default_gravity”)

func _ready():
Input.mouse_mode = Input.MOUSE_MODE_CAPTURED

func _input(event):
if event is InputEventMouseMotion:
rotate_y(deg_to_rad(-event.relative.xsens_horizontal ))
camera_mount.rotate_x(deg_to_rad(-event.relative.ysens_vertical))
func _phisics_process(delta):
# Add the gravity.
if not is_on_floor():
velocity.y -= gravity * delta

Handle jump.

if Input.is_action_just_pressed("ui_accept") and is_on_floor():
	velocity.y = JUMP_VELOCITY

# Get the input direction and handle the movement/deceleration.
# As good practice, you should replace UI actions with custom gameplay actions.
var input_dir := Input.get_vector("left", "right", "forward", "backward")
var direction := (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
if direction:
	velocity.x = direction.x * SPEED
	velocity.z = direction.z * SPEED
else:
	velocity.x = move_toward(velocity.x, 5.0, SPEED)
	velocity.z = move_toward(velocity.z, 5.0, SPEED)

move_and_slide()

get_vector() is already normalized, so normalizing direction is redundant. Instead of multiplying input_dir by transform basis, just call .rotated(-player_rotation.y) on the input_dir variable. Then just multiply that by speed.

Can you share a screenshot of your InputMap? Maybe you did not assign Inputs to the Actions?

Doesn’t seem like your code should inhibit movement, but it’s hard to tell without proper formatting

Hello thanks for responding, here is my input map and script:

and my script:

extends CharacterBody3D

@onready var camera_mount: Node3D = $Camera_Mount



const SPEED = 5.0
const JUMP_VELOCITY = 4.5

@export var sens_horizontal = 0.5
@export var sens_vertical = 0.5

# Get the gravity from the project settings to be synced with RigidBody nodes.
var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")
		
func _ready(): 
	Input.mouse_mode = Input.MOUSE_MODE_CAPTURED
	
func _input(event): 
	if event is InputEventMouseMotion: 
		rotate_y(deg_to_rad(-event.relative.x*sens_horizontal )) 
		camera_mount.rotate_x(deg_to_rad(-event.relative.y*sens_vertical))
func _phisics_process(delta):
	# Add the gravity.
	if not is_on_floor():
		velocity.y -= gravity * delta



# Handle jump.
	if Input.is_action_just_pressed("ui_accept") and is_on_floor():
		velocity.y = JUMP_VELOCITY

	var input_dir := Input.get_vector("left", "right", "forward", "backward")

	if direction:
		velocity.x = direction.x * SPEED
		velocity.z = direction.z * SPEED
	else:
		velocity.x = move_toward(velocity.x, 5.0, SPEED)
		velocity.z = move_toward(velocity.z, 5.0, SPEED)

	move_and_slide()

Hello, thanks for the help, I tried this and it keeps giving me the error message “Closing “)” doesn’t have an opening counterpart.”

heres how I implemented it, im very new to coding so forgive me if I completely botched this:

var input_dir := Input.get_vector("left", "right", "forward", "backward")
	var direction :=  call .rotated(-player_rotation.y) * Vector3(input_dir.x, 0, input_dir.y))

You mispelled “_physics_process” ← right spelling, what you put → “_phisics_process”
