How best would I create a rig that allows character movement and collision detection while also having a top down style camera that follows the player, allowing the player to rotate independently of the camera orientation? Also, Node3D doesn't have a function called "move_and_collide()", so is there a better node I should be using in it's place? The following is the code I am currently using.

extends Node3D

var rotationSpeed: float = 1.35
var rotationInput: int = 0
var movementSpeed: int = 5
var inputVector: Vector2 = Vector2()
var movementVector: Vector3 = Vector3()

func _ready() -> void:
	pass

func _process(delta: float) -> void:
	# Handle Movement
	movementVector.x = Input.get_action_strength("move_right") - Input.get_action_strength("move_left")
	movementVector.z = Input.get_action_strength("move_backward") - Input.get_action_strength("move_forward")
	movementVector = movementVector.normalized() * delta * movementSpeed
	translate(movementVector)
	# Handle Rotation
	rotationInput = Input.get_action_strength("rotate_right") - Input.get_action_strength("rotate_left")
	rotate_y(delta * rotationSpeed * rotationInput)

  • Lousifr The function name is set_as_top_level not set_as_toplevel. You can also just assign a value to node's top_level property.

    You probably want to use a character3d node. The camera, you set an offset from the player in process and have it lookat the player. generally, you add a focal point for the camera that is about at the character's neck. A 3d node or whatever parented to the character.

    I think the easiest way to do this is make a 'SrpingArm' camera and attach it to a node that is always relative to player position, then rotate the SpringArm camera, rather than rotating the 'player' camera attached to the CharacterBody3D.

    I found this demo helpful for my third-person mode, especially player/player.gd
    Sounds like you want a birds-eye 'isometric' view but this is pretty similar.
    Either way it's more complicated than first-person, so take your time to understand the geometry.

    This video does exactly what I want, but it's written for Godot 3, not Godot 4. The following is the code I've written so far, but I'm having trouble updating the code to GDScript 4.

    extends CharacterBody3D

# Get the gravity from the project settings to be synced with RigidBody nodes.
var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")

@export var speed = 10.0
@export var camera_rotation = 25

@onready var camera = $CameraRig/Camera
@onready var camera_rig = $CameraRig
@onready var cursor = $Cursor

func _ready():
	pass

func _physics_process(delta):
	# Handle gravity.
	if not is_on_floor():
		velocity.y -= gravity * delta

	# Get the input direction and handle the movement/deceleration.
	var input_dir = Input.get_vector("move_left", "move_right", "move_forward", "move_backward")
	var direction = (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
	if direction:
		velocity.x = direction.x * speed
		velocity.z = direction.z * speed
	else:
		velocity.x = move_toward(velocity.x, 0, speed)
		velocity.z = move_toward(velocity.z, 0, speed)

	move_and_slide()

    In the _ready function, I'm supposed to use the function "set_as_toplevel(true)" on the camera rig and the cursor, but this function doesn't exist in Godot 4. What do I use in its place?
