I tried to follow a video to make portals in my 2d game, but the following error continued to show:
Error at (3, 1): Unexpected “Identifier” in class body.
Code:
extends Area2D
export(int) var id = 0
var lockPortal = false
func LockedPortal():
lockPortal = true
yield(get_tree().create_timer(0.5), “timeout”)
lockPortal = false
func _ready():
pass
Any help is greatly appreciated
This looks like a Godot 3 code, and your post is tagged godot-4. In Godot 4, you must use @export instead of export, and yield was replaced by await.
Yess thank you!
Im new to godot and I didn’t realize there was a change.
That works but theres a new problem now lol
Error at (9, 39): Expected closing “)” after grouping expression.
which is during this line:
await(get_tree().create_timer(0.5), “timeout”)
[39 is between ) and ,]
The syntax is different. It should be like this:
await get_tree().create_timer(0.5).timeout
There were further changes between Godot 3 and 4. Check out this page: Upgrading from Godot 3 to Godot 4 — Godot Engine (stable) documentation in English
Thanks heaps, the errors are gone but unfortunately the function still isnt working. Ill have to scrap this code and try find a new way to make these portals work.
thanks anyway!
bro, can you help me too? This code was written by ChatGPT. Mistake 1 line: Unexpected “Identifier” in class body
extends Area2D
# Ссылка на Polygon2D
onready var polygon = $Polygon2D
# Исходный цвет
var original_color = Color(1, 1, 1) # Белый
var new_color = Color(1, 0, 0) # Красный
func _ready():
# Подписываемся на событие ввода
self.connect("input_event", self, "_on_input_event")
func _on_input_event(viewport, event, shape_idx):
if event is InputEventMouseButton:
if event.pressed:
# Меняем цвет полигонa на новый
var material = polygon.material
if material is CanvasItemMaterial:
material.color = new_color
else:
var new_material = CanvasItemMaterial.new()
new_material.color = new_color
polygon.material = new_material
If you use Godot 4, this line should start with @onready.
Bro, you’re my savior.
Even ChatGPT4.o failed
You are welcome. The AI is still not all-powerful. It can show you the way, but you also need to understand the code it suggests.
Help me too please, I am getting error at sync variables .

I have trouble with a headbob script i saw in a tutorial for godot 4

move_and_slide()
func _headbob(time) -> Vector3:
var pos = Vector3.ZERO
pos.y = sin(time * BOB_FREQ) * BOB_AMP
return pos
You need to indent your headbob part of the code.
Assuming there are no other problems with your code, because you never specified what’s the issue.
Oh I forgot to mention that. I just had trouble why i had a syntax error with the headbob script. Since I added the indentation, I had a another error On line 66 # Head bob t_bob += delta * velocity.length() * float(is_on_floor()) camera.transform.orgin = _headbob(t_bob)“Invalid assignment of property or key ‘orgin’ with value of type ‘Vector3’ on a base object of type ‘Transform3D’.”
You misspelled origin.
oh, lol
Hey could you help me too, i have this but getting an error from line 7

func _input(event):

This needs to be @export
If you use Godot 4, this line should start with @export.
i also need help with the same issue here is my code:

var direction := Input.get_axis("ui_left", "ui_right")
if direction:

else:
