Cannot get 3D character to flip on the X axis

Question

Hi, I am trying to flip my character, but I cannot get it to work, it’s printing the numbers correctly, but I cannot visually see the character changing orientation.

Code

extends CharacterBody3D


@export var speed = 7
@export var jumpPower = 15

@onready var camera_controller: Node3D = $Camera_controller

# Called when the node enters the scene tree for the first time.
func _ready() -> void:
	scale.x = 1


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
	pass


func _physics_process(delta: float) -> void:
		
	if(!is_on_floor()):
		velocity += get_gravity()
	elif(Input.is_action_just_pressed("jump")):
		velocity.y = jumpPower
	
	var dir = Input.get_axis('left' , 'right')
	
	if(dir):
		velocity.x = dir * speed
	else:
		velocity.x = move_toward(velocity.x , 0 , speed)
		
	move_and_slide()
		
	camera_controller.position = lerp(camera_controller.position , position , 0.1)
	
	if Input.is_action_pressed('right'):
		scale.x = 1
	elif Input.is_action_pressed("left"):
		scale.x = -1
		
	print(scale.x)

I have no clue why it is not working and help is greatly appreciated.

How can you tell if it’s working? What happens vs what do you expect to happen?

I have made some advancments in my code, it flips, but it flips weirdly. Like in this video:

I want the player to flip along the X axis when the different buttons are being pressed. I there’s a better more efficient way, I would gladly hear about it. I do not know if I answered your question correctly though

Code

extends CharacterBody3D


@export var speed = 7
@export var jumpPower = 15

@onready var camera_controller: Node3D = $Camera_controller

# Called when the node enters the scene tree for the first time.
func _ready() -> void:
	scale.x = 1


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
	pass


func _physics_process(delta: float) -> void:
		
	if(!is_on_floor()):
		velocity += get_gravity()
	elif(Input.is_action_just_pressed("jump")):
		velocity.y = jumpPower
	
	var dir = Input.get_axis('left' , 'right')
	
	if(dir):
		velocity.x = dir * speed
	else:
		velocity.x = move_toward(velocity.x , 0 , speed)
		
	move_and_slide()
		
	camera_controller.position = lerp(camera_controller.position , position , 0.1)
	
	if Input.is_action_just_pressed("right"):
		scale = Vector3(1,1,1)
	elif Input.is_action_just_pressed("left"):
		scale = Vector3(-1,1,1)
		
	print(scale.x)

Edit:

When I meant “Different buttons are being pressed” I meant the left and right buttons.

Ok… I finally got it working. I had to rather instead of shifting the s
scale, I rather shifted the rotation. My number is EXTREMLY specific, coming from the print result in the console. So other peoples directions will vary. This is how the code looks.

Code

extends CharacterBody3D


@export var speed = 7
@export var jumpPower = 15

@onready var camera_controller: Node3D = $Camera_controller

var LeftOrRight = null

# Called when the node enters the scene tree for the first time.
func _ready() -> void:
	scale.x = 1


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
	pass


func _physics_process(delta: float) -> void:
		
	if(!is_on_floor()):
		velocity += get_gravity()
	elif(Input.is_action_just_pressed("jump")):
		velocity.y = jumpPower
	
	var dir = Input.get_axis('left' , 'right')
	
	if(dir):
		velocity.x = dir * speed
	else:
		velocity.x = move_toward(velocity.x , 0 , speed)
		
	move_and_slide()
		
	camera_controller.position = lerp(camera_controller.position , position , 0.1)
	
	if Input.is_action_just_pressed("right"): #Checks if right, if so, set LeftOrRight to "right"
		LeftOrRight = "right"
	elif Input.is_action_just_pressed("left"): # Checks if left, if so, set LeftOrRight to "left"
		LeftOrRight = "left"
		
	#Now we check what direction we are
	if(LeftOrRight == "right"): #If 'LeftOrRight' is equal to "right" then execute the code
		rotation.y = -1.570796
	elif(LeftOrRight == "left"): #If 'LeftOrRight' is equal to "left" then execute this block of code
		rotation.y = 1.570796
		
	print(rotation)

This number is -PI/2, try to use this constant instead. Or deg_to_rad(-90)

Scale was probably the wrong move in the long run. Physics bodies do not like non-uniform scaling, maybe the CharacterBody3D would reset the scale silently.
