Player's forward movement slows with camera angle

Question

Currently the code setup I have for my camera is based on a node rotating both on the y axis and x axis. Unfortunately the way I set up my character's movement relative to the camera has the character slowing down on the x axis with the rotation of the camera

extends CharacterBody3D
var gravity = 14
var Player = {
“level”: 1,
“experience”: 0,
“health” :10,
“mp” : 1,
“strength”: 1,
“def” : 1,
“ap”: 1,
“jump_height”: 400,
“speed”: 5
}
func _physics_process(delta):
#Shmoving
var input_dir = Input.get_vector(“move_left”, “move_right”, “move_up”, “move_down”)
var direction = ($Pivot.transform.basis * Vector3(input_dir.x,0,input_dir.y)).normalized()

if direction:
	velocity.x = direction.x * Player.speed
	print(velocity.x)
	velocity.z = direction.z * Player.speed
	print(velocity.z)
else:
	velocity.x = 0
	velocity.z = 0
#JUMPING BEAN
if Input.is_action_pressed("jump") and is_on_floor():
	if velocity.z > 0 or velocity.x > 0:
		velocity.y = Player.jump_height * delta
	else:
		velocity.y = Player.jump_height * delta
#Face direction
if input_dir != Vector2(0,0):
		$Sprite3D.rotation_degrees.y = $Pivot.rotation_degrees.y - rad_to_deg(input_dir.angle()) + 90
#CRASHING BEAN SORA
if not is_on_floor():
	velocity.y -= gravity * delta
move_and_slide()

I’m hoping someone else has a better solution to this

I don’t really understand what is the problem you’re having and what’s your expectation? Could you clarify? Ideally with a short video of the behavior.
Please paste your code as preformatted text with triple backticks ``` at the beginning and end of the code snippet.

	velocity.x = direction.x * Player.speed
	print(velocity.x)
	velocity.z = direction.z * Player.speed
	print(velocity.z)

	velocity.x = 0
	velocity.z = 0

This piece of movement code uses the pivoting node for the camera to move in the direction the camera faces so forward is relative to the camera, which causes a problem when the camera faces either down or up and the camera’s “forward” leans into the floor, slowing the movement speed.

( I tried uploading a video of the issue but I’m a new user)

tldr; the forward movement speed drops when the camera faces down or up cuz the forward is based on pivot angle

Typically others rotate the character node around the Y axis and the camera node around the X axis, this separation allows the character’s basis to remain parallel to the floor, so using basis * Vector3(input_dir.x,0,input_dir.y) results in a planar movement relative to the character’s facing direction.
