Trying to make my character look wherever I move

[WyvernZ22]

I was able to implement mouse input and make my character face whatever the camera was looking at, but I couldn't make it face left, right, or back. How can I implement that in my script? I'm pretty new to coding and godot.

extends CharacterBody3D

const MAX_SPEED = 10.0
const ACCELERATION = 20.0
const DECELERATION = 20.0
const JUMP_VELOCITY = 4.5

var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")
var phantomCamera: PhantomCamera3D
var mouseSensitivity: float = 0.05

var minYaw: float = -89.9
var maxYaw: float = 50

var minPitch: float = 0
var maxPitch: float = 360

func _ready():
	# Find the Phantom Camera node by its path
	phantomCamera = $%PhantomCamera3D  # Update this with the correct path to your Phantom Camera node

	# Set mouse mode to captured to hide the cursor and confine it within the game window
	Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _physics_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.
	var input_dir = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
	var direction = (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
	
	if direction:
		# Apply acceleration towards the maximum speed
		var target_speed = direction.length() * MAX_SPEED
		velocity.x = lerp(velocity.x, direction.x * target_speed, ACCELERATION * delta)
		velocity.z = lerp(velocity.z, direction.z * target_speed, ACCELERATION * delta)

		# Update the character's rotation based on camera rotation when moving forward or backward
		if phantomCamera != null:
			var cameraRotation = phantomCamera.global_transform.basis.get_euler()
			if direction.z != 0:  # Moving forward or backward
				$%Character.rotation.y = cameraRotation.y
			else:  # Moving left or right
					var targetRotation = cameraRotation.y + atan2(direction.x, direction.y)
					$%Character.rotation.y = lerp_angle($%Character.rotation.y, targetRotation, 0.1)

	else:
		# Apply deceleration if not moving
		velocity.x = move_toward(velocity.x, 0, DECELERATION * delta)
		velocity.z = move_toward(velocity.z, 0, DECELERATION * delta)

	# Clamp velocity to the maximum speed
	velocity.x = clamp(velocity.x, -MAX_SPEED, MAX_SPEED)
	velocity.z = clamp(velocity.z, -MAX_SPEED, MAX_SPEED)

	# Update camera position to follow the player
	if phantomCamera != null:
		phantomCamera.global_transform.origin = global_transform.origin

	# Set animation parameters
	$AnimationTree.set("parameters/conditions/idle", input_dir == Vector2.ZERO && is_on_floor())
	$AnimationTree.set("parameters/conditions/walk", input_dir != Vector2.ZERO && is_on_floor())
	$AnimationTree.set("parameters/conditions/falling", !is_on_floor())
	$AnimationTree.set("parameters/conditions/landed", is_on_floor())
	
	move_and_slide()

func _unhandled_input(event: InputEvent) -> void:
	if event is InputEventMouseMotion:
		if phantomCamera != null && phantomCamera.global_transform != null:
			var pcamRotationDegrees = phantomCamera.get_third_person_rotation_degrees()

			# Change the X rotation
			pcamRotationDegrees.x -= event.relative.y * mouseSensitivity
			# Clamp the rotation in the X axis so it doesn't go over or under the target
			pcamRotationDegrees.x = clampf(pcamRotationDegrees.x, minYaw, maxYaw)

			# Change the Y rotation value
			pcamRotationDegrees.y -= event.relative.x * mouseSensitivity
			# Sets the rotation to fully loop around its target, but without going below or exceeding 0 and 360 degrees respectively
			pcamRotationDegrees.y = wrapf(pcamRotationDegrees.y, minPitch, maxPitch)

			# Change the Phantom Camera node's rotation and rotate around its target
			phantomCamera.set_third_person_rotation_degrees(pcamRotationDegrees)

If you wouldn't mind, could you potentially update the first post you wrote by writing a comment instead of making a separete follow-up post. Makes it a bit difficult to track and help otherwise.

@ramokz Sorry about that. I just went back to the first post. I hope I didn't cause much of an issue.

Not at all! It's just to have a single conversation timeline rather than remembering there were multiple :)
