none of these worked. Found this tutorial and was trying to implement in 4.2 but facing an error. any idea how to solve ?
an error : position = lerpf(position, target_position, smoothing)
"Invalid argument for lerpf() function: argument 1 should be “float” but is “Vector2”
extends Camera2D
var smoothing: float
@export var follow_smoothing: float = 0.1
@export var current_room_center: Vector2
@export var current_room_size: Vector2
@export var zoom_view_size: Vector2
@onready var view_size: Vector2 = get_viewport_rect().size
@onready var player = get_node("../player")
func _ready():
position_smoothing_enabled = false
smoothing = 1
await get_tree().create_timer(0.1).timeout
smoothing = follow_smoothing
func _physics_process(delta):
zoom_view_size = view_size * zoom
var target_position := calculate_target_position(current_room_center, current_room_size)
position = lerpf(position, target_position, smoothing)
func calculate_target_position(room_center: Vector2, room_size: Vector2) -> Vector2:
var x_margin: float = (room_size.x - zoom_view_size.x) / 2
var y_margin: float = (room_size.y - zoom_view_size.y) / 2
var return_position: Vector2 = Vector2.ZERO
if x_margin <= 0:
return_position.x = room_center.x
else:
var left_limit: float = room_center.x - x_margin
var right_limit : float = room_center.x + x_margin
return_position.x = clampf(player.position.x, left_limit, right_limit)
if y_margin <= 0:
return_position.y = room_center.y
else:
var top_limit: float = room_center.y - y_margin
var bottom_limit: float = room_center.y + y_margin
return_position.y = clampf(player.position.y, top_limit, bottom_limit)
return return_position
