Godot Version
4.4.1
Question
I’m a complete beginner and I’ve been stuck on this for a very long time. Please help me. Part of me thinks it’s because my character isn’t facing the direction it’s moving. I’ve tried to fix this, but there are still bugs. This is the best version of my code so far.
extends CharacterBody3D
@export var camera:Camera3D
@onready var animation_tree = $AnimationTree
const SPEED = 5.0
const JUMP_VELOCITY = 4.5
var acceleration := 25.0
var angular_acceleration := 7
func _process(_delta: float) -> void:
if camera == null:
return
var to_camera = (camera.global_transform.origin - global_transform.origin).normalized()
var fwd := global_transform.basis.z
var left := global_transform.basis.x
var dot_fwd = fwd.dot(to_camera)
var dot_left = left.dot(to_camera)
var angle = rad_to_deg(atan2(dot_left, dot_fwd))
if angle < 0:
angle += 360
var snapped = int(round(angle / 45.0)) * 45 % 360
var dir_vector = Vector2.RIGHT.rotated(deg_to_rad(snapped)).normalized()
update_animation_parameters(dir_vector)
func _physics_process(delta: float) -> void:
## --- GRAVITY --- ###
if not is_on_floor():
velocity += get_gravity() * delta
# Handle jump.
#if Input.is_action_just_pressed("jump") and is_on_floor():

## --- MOVEMENT --- ##
var input_dir := Input.get_vector("move_left", "move_right", "move_up", "move_down")
var direction := (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
direction = direction.rotated(Vector3.UP, camera.global_rotation.y)
if direction:
if is_on_floor() and velocity.y <= 0:
velocity.x = direction.x * SPEED
velocity.z = direction.z * SPEED
set_moving(true)
else:
velocity.x = move_toward(velocity.x, 0, delta * acceleration)
velocity.z = move_toward(velocity.z, 0, delta * acceleration)
set_moving(false)

func set_moving(value):

animation_tree["parameters/conditions/idle"] = not value
func update_animation_parameters(input_dir:Vector2):
if input_dir == Vector2.ZERO:
return
animation_tree.set("parameters/idle/blend_position", input_dir)

I can’t upload the video, so I’ll just share the link instead.
