Invalid assignment of property or key 'RespawnPoint' with value of type 'Vector2' on a base object

[past escarp]

it won't let me change variables because it's type nil.
i'm making a save system and this part in particular is bugging out. heres the error message, is there a fix for this?
im using .tres to save files

Invalid assignment of property or key 'RespawnPoint' with value of type 'Vector2' on a base object of type 'Nil'.

i'm gonna go to sleep hopefully someone replies in the morning

[slender jackal]

it depends on what you're code looks like
from the error, im assuming that you have a variable named RespawnPoint that you're trying to set with a Vector2, makes perfect sense
but the problem is that you're trying to access it before it's initialized? i'm honestly not sure, it would be much easier if your code was there to see

[past escarp]

yeah you got it basically spot on

[slender jackal]

did you fix it?

if not can you provide your code?

[past escarp]

the engine's still loading hold on

okay

[past escarp]

here's the code for checkpoint.gd

extends Area2D

func _on_body_entered(body: Node2D) -> void:
if body.is_in_group("Player"):
print("wrong body actually :'(")
SaveData.RespawnPoint = get_node("SpawnPoint").global_position
print(SaveData.RespawnPoint)

and for SaveData

extends Resource

class_name SaveDataResource

@export var HasResize = false
@export var Dashes = 0
@export var RespawnPoint = Vector2(1,1)

[slender jackal]

where are you loading save data resource?

[past escarp]

its an autoload

[slender jackal]

uhh I don’t think that will save across sessions

shouldn’t you be using ResourceLoader and ResourceSaver? (I learned about those yesterday trying to reproduce your problem lol)

[past escarp]

im pretty sure those load files, not scripts

might be wrong tho

[slender jackal]

yeah and the file is the resource

I think you’re misunderstanding how a resource works, you don’t modify the script itself, you make a new resource that extends from your custom resource and change that

[past escarp]

so how do i access said resource from other scripts

[slender jackal]

that’s what resourceloader and saver is for

[past escarp]

so i load the resource at the start of the script i assume

[slender jackal]

yeah

resourceloader is a class with method load where you can load a resource

I don’t really know as to how to implement this since I actually just learned this yesterday

Honestly I used JSON in user:// for my saving but it seems this is easier

[past escarp]

I WAS GOING TO USE JSON TOO 😭

atp should i swap back to json

actually i learned somewhere that json doesnt work with vector2s

[slender jackal]

IMO if you have a thing that needs saving (in any context or language) json would be my go to

but if they provide you with a solution like ResourceLoader and Saver that was made with the literal intention for saving then that one is probably much easier

[slender jackal]

Well yeah JSON is used everywhere not just in Godot, you can’t expect it to be able to store everything Godot has

[past escarp]

would there be some way to "translate" json to vector2

[slender jackal]

Well vector2 in terms of storage is literally just two numbers

You can store it as a list [0, 0] with 0th element being X and 1st element being Y

Then in Godot you can just say Vector2(pos[0], pos[1])

[past escarp]

well guess i'll set up that json save system again

[slender jackal]

consider this though

looking at a few examples resources actually look much better than json, as long as you know how to use them

[past escarp]

ok so

go back to the start

is there a way to start funtions ONLY when the game is ready?

[slender jackal]

ok wait it seems json might be a better approach

https://www.reddit.com/r/godot/comments/1f06nqx/are_resources_still_unsafe_in_current_godot/?chainedPosts=t3_1ax6mae

idk I’ve just been looking around

[slender jackal]

wouldn’t that be the ready function on nodes?

[past escarp]

okay so if resources arent safe then i'm DEFINITELY using json

even if it's not that big of a game

[slender jackal]

Yea it’s not that hard with FileAccess

I’d be glad to send some of my code (when im home)

[past escarp]

thanks

[past escarp]

oha and please do ;-;

[slender jackal]

this is how you parse it as dictionary

annd this is how i save, note that its obviously not the same

[past escarp]

if you dont mind telling me- how do i connect variables to the JSON file?

[past escarp]

new problem

Invalid assignment of property or key 'RespawnPoint' with value of type 'Vector2' on a base object of type 'Node (Save-Load.gd)'.

i followed a tutorial on how to set JSON up and this is happening when i try and use Vector2d

[slender jackal]

you don't

you set it as a key

{
  "This is the actual variable name": "Variable Value"
}

[past escarp]

like this/

?

@slender jackal

[slender jackal]

yea

thats perfect

[past escarp]

k

is there a way to access dictionaries in other scripts?

@slender jackal sorry for pinging

[slender jackal]

depends on what

stored in json? yes
