Invalid get index 'orbit_position' (on base: Area2D (circle.gd)').

Question

I'm currently following this tutorial by @kidscancode
I'm only at part 1 and I've already hit a wall
via this line: transform = target.orbit_position.global_transform

The error shown in the title happens after the object/node 'jumper' hits the object/node 'circle' upon running the scene.

The root/parent-most node of each scenes colliding that are attached to each of the scripts are of type: Area2D

This is the code of the problem script:
jumper.gd

extends Area2D

var velocity = Vector2(100, 0) # start value for testing

var jumpSpeed = 1000

var target = null # if we're on a circle

func unhandledinput(event):

    if target and event is InputEventScreenTouch and event.pressed:

        jump()

func jump():

    target = null

    velocity = transform.x * jumpSpeed

func onjumperareaentered(area):

    target = area

    velocity = Vector2()

func physicsprocess(delta):

    if target:

        transform = target.orbitposition.globaltransform

    else:

        position += velocity * delta

This is what it's hitting.
circle.gd

extends Area2D

onready var orbitPosition = $pivot/orbitPosition

var radius = 100

var rotationSpeed = PI

func _ready():

    init()

func init(radius = radius):

    radius = _radius

    $CollisionShape2D.shape = $CollisionShape2D.shape.duplicate()

    $CollisionShape2D.shape.radius = radius

    var imgSize = $Sprite.texture.getsize().x / 2

    $Sprite.scale = Vector2(1, 1) * radius / imgSize

    orbitPosition.position.x = radius + 25

func _process(delta):

    $pivot.rotation += rotationSpeed * delta

I watched the video version of the tutorial and changed my project settings and everything else accordingly but the result is still the same.

Any ideas/hints to fix this?

Answer 1

I guess it's just typo.

you are referring orbit_position in jumper.gd

transform = target.orbit_position.globaltransform

but it's defined as orbitPosition in circle.gd

it's simply orbit_position vs orbitPosition

Comments

Thank you so much!

I didn't know that area from the _on_jumper_area_entered(area) method was actually an object referring to circle.gd

This really helped! Thanks!
