Question

Hello I’m trying to figure out how to capture movement of right joystick on xbox controller to emulate movement of mouse cursor .

current code working with mouse capturing ( from GameDev course )

extends CharacterBody3D


const SPEED = 5.0
const JUMP_VELOCITY = 4.5


var _look := Vector2.ZERO

@export var mouse_sensitivity: float = 0.00075
@export var min_boundry: float = -60
@export var max_boundry: float = 10
@export var animation_decay: float = 20.0

@onready var horizontal_pivot: Node3D = $HorizontalPivot
@onready var vertical_pivot: Node3D = $HorizontalPivot/VerticalPivot
@onready var rig_pivot: Node3D = $RigPivot
@onready var rig: Node3D = $RigPivot/Rig




func _ready() -> void:
	Input.mouse_mode = Input.MOUSE_MODE_CAPTURED
	
func _physics_process(delta: float) -> void:
	frame_camera_rotation()
	
	if not is_on_floor():
		velocity += get_gravity() * delta

	if Input.is_action_just_pressed("jump") and is_on_floor():
		velocity.y = JUMP_VELOCITY
		
	var direction = get_movement_direction()
	rig.update_animation_tree(direction)
	if direction:
		velocity.x = direction.x * SPEED
		velocity.z = direction.z * SPEED
		look_toward_direction(direction, delta)
		
	else:
		velocity.x = move_toward(velocity.x, 0, SPEED)
		velocity.z = move_toward(velocity.z, 0, SPEED)

	move_and_slide()

func _unhandled_input(event: InputEvent) -> void:
	if event.is_action_pressed("esc"):
		if Input.mouse_mode == Input.MOUSE_MODE_CAPTURED:
			Input.mouse_mode = Input.MOUSE_MODE_VISIBLE
		else:
			Input.mouse_mode = Input.MOUSE_MODE_CAPTURED
		
	if Input.mouse_mode == Input.MOUSE_MODE_CAPTURED:
		if event is InputEventMouseMotion:
			_look += -event.relative * mouse_sensitivity

func get_movement_direction() -> Vector3 :
	var input_dir := Input.get_vector("move_left", "move_right", "move_forward", "move_back")
	var input_vector := Vector3(input_dir.x, 0, input_dir.y).normalized()
	return horizontal_pivot.global_transform.basis * input_vector

func frame_camera_rotation() -> void :
	horizontal_pivot.rotate_y(_look.x)
	vertical_pivot.rotate_x(_look.y)
	
	vertical_pivot.rotation.x = clampf(
		vertical_pivot.rotation.x,
		deg_to_rad(min_boundry),
		deg_to_rad(max_boundry)
		)
	
	_look = Vector2.ZERO
	

func look_toward_direction(direction: Vector3, delta: float) -> void :
	var target_transform := rig_pivot.global_transform.looking_at(
		rig_pivot.global_position + direction, Vector3.UP, true 
	)
	rig_pivot.global_transform = rig_pivot.global_transform.interpolate_with(
		target_transform,
		1.0 - exp(-animation_decay * delta)
	)

What have you tried? What does not work?

I have tried to add this


var look_x := Input.get_joy_axis(0, JOY_AXIS_RIGHT_X)
	var look_y := Input.get_joy_axis(0, JOY_AXIS_RIGHT_Y)
	if abs(look_x) > 0.15 or abs(look_y) > 0.15:
		look_y = -look_y
		_look += Vector2(look_x, look_y) * controller_sensitivity * delta

The docs recommend to setup input actions first for the joystick.

You can get a full motion vector from the joystick with:

Input.get_vector("move_left", "move_right", "move_forward", "move_back")

The input for walk is fine , it’s about smoothing camera rotation via rest of the code , character movement is assigned to left stick , and right do camera rotation same as mouse movement , plus B/esc is for stop capturing mouse .

This is played with Xbox controller via USB-C on Mac .
