Invalid get index 'position' (on base: 'Node) -- Please assist

outermindarts

My game setting is in outer space. I want randomly generate more two types of asteroids for the player/flyer to dodge towards its destination. I keep getting the title error above.

I just want them to appear in the 3D world when the game loads. Please advise.

` extends Node

func _ready():

var rand = RandomNumberGenerator.new()
var asteroidscenes = load("res://scenes/Asteroid1.tscn")

var screen_size = get_viewport().get_visible_rect().size

for i in range(0, 10):
	var asteroids = asteroidscenes.instance(i)
	rand.randomize()
	var x = rand.randf_range(0, screen_size.x)
	rand.randomize()
	var y = rand.randf_range(0, screen_size.y)
	asteroids.position.y = y
	asteroids.position.x = x
	add_child(asteroids)

You might needs set position after add_child. I know in 3D I have to add_child, then I can set the origin. I get an error if I try different order.

@newmodels Thank you, for the suggestion. I tried it and it did not work.

Welcome to the forums @outermindarts!

position is for 2D nodes. The equivalent is translation, if you are wanting to offset the node relative to its parent, or transform.origin, depending on which you want to use. If you want to move the object globally, relative to the origin of the world, you need to modify global_transform.origin

@TwistedTwigleg Thank you. I am new to scripting. I want to have asteroids scattered throughout the game world.

Are you suggesting that I call translation.origin or transform.origin above line 12?

If I were to call global_transform.origin, would I call it above line 7?

I would suggest transform.origin. Also, you can just modify the translation directly, there is no origin property in translation.

No, you’d probably want to put it around or after line 11
