Balls. What is it you're trying to do? Might be another way around it

Just call the get actors of class function?

[brave cosmos]

can't do it in an object

[proven pine]

what you need world for ?

[brave cosmos]

I am trying to create like a component for level blueprint so it can stay isolated and filtered however level blueprint can't have components so I thought of using object but the object doesn't have access to the world freely

[proven pine]

why do you want a component on level blueprint ?

using level blueprint is usually not recommended

[brave cosmos]

I am basically trying to get a specific component from all the actors in the world and set them up. Since this acts as global variable which they all use to submit and receive orders from

[open nymph]

I think you want to look into a GameState class potentially?

[brave cosmos]

I wanted something that persists through out the level

[open nymph]

Or, a world subsystem

[brave cosmos]

I will have to look into both of these things

[proven pine]

many things persist throughout the level

game mode, game state

hud, a manager actor

any actor you don't remove from the scene should be "persistent"

[brave cosmos]

I see I will look into those. I basically wanted this to work closely with the game saving system and I though something like this would seem better

[open nymph]

Ok yeah, you definitely want a GameInstance, GameMode or GameState class.

My game saving logic usually lives in the GameInstance as it's available from the moment your game starts

[brave cosmos]

I am basically creating a component that specifically stores the current progress of the game and its objective to the save system so I needed it to be somewhere from where it can be accessed easily and I only know about gameinstance and levelinstance to store things globally

[brave cosmos]

but the problem with this is that this needs the reference to the world as well since its the one doing the saving and not just getting called by the world but sadly game instance being an object doesn't have reference of the current level

so it can only get called by the world and can't directly interact with the world

[proven pine]

what do you need to interact ?

the game instance is the only thing that persists through multiple levels

[brave cosmos]

like here when I try to get all the actors in the world

[proven pine]

so your pretty much stuck with it

[proven pine]

get all actors of class

is all in the world

[brave cosmos]

yes and it doesn't work in the object that is the problem

[proven pine]

are you saying you need world context ?

you can pass any actor

[brave cosmos]

I have to go for now. Thank you for the help so far

[proven pine]

this is a blueprint function library

you need to world context

and you just pass any actor in

[brave cosmos]

Allow me to elaborate on what I am doing. I am creating a component(isolated part) whose only job is to store the progress of events that are currently waiting to be completed and the ones that are completed. So it basically saves the current state of the gameplay and not the player itself. Its only task is to load the level's state to what it was before quiting/saving the game. As just it needs to be binded to the level alone as it needs to only work when the level begins or when the player quits the level. And as this component is responsible for loading the state of the gameplay at runtime it needs to get the reference of the world to set it as per saved data and thats why it needs the world reference.

[proven pine]

"you cannot directly attach a component to the "world" in Unreal Engine because components are designed to be attached to other components or actors" -AI

[brave cosmos]

As for this I've already tried it but I guess its bug in unreal that function library's change doesn't get updated too quickly for now I am about the game state and world subsystem for now. and then I'll decide where exactly to attach this componenet

[brave cosmos]

yes that why I am using an object so I can store it in a variable

[proven pine]

so ig you can have a save for each level

[brave cosmos]

and for where I should store it, in level blueprint, gamemode or if any other place is recommend please do tell.

[proven pine]

i don't understand what it's storing ?

what is thing even doing ?

wdym the levels state ?

[brave cosmos]

at each level the component needs to load the state from the save file so each level needs either their own such component or they need to call it it every time in the game state

[subtle widget]

noob question. why we cant just put actor in level -> add component to this actor -> craete some dispatchers/interfaces to tell him when to do his saving stuff?

[proven pine]

yes a amanager actor you can defiantely use, but each level would require a custom one

[proven pine]

definately not the level blueprint

[brave cosmos]

basically if player has a bunch of objectives. Its storing which ones have been completed and which ones are next as well as which subsequent areas has been unlocked a result of completing the old objectiv3es

[proven pine]

idk why you need world

just an array of objectives would be fine

make an objective struct, make an array, flip a boolean on completed

[brave cosmos]

Becasue the checkpoints that monitoring the progress of the player are present on the world

and they needs to be adjusted to the saved state when the saved file is loaded

[proven pine]

well idk about the saving/loading part that may need world

[brave cosmos]

I am not mearly monitoring them but also managing them telling them when to be active and when to be dormant

[proven pine]

but it doesn't sound like you need world at all

[brave cosmos]

probably

for now I just want to know the best place to store this component

[proven pine]

it's not a component

it would just be some functions

unless you use a manager actor

like mentioned you can do that

[brave cosmos]

Thats a valid approach that I found online but that sounds like an overkill

[proven pine]

at which point you would attach the component

[subtle widget]

hm. i have checkpoint. but they save rn only character/chest position. Just put it in world. and the contact my BP_SaveGame. thats all

[brave cosmos]

yeah let says its some function but where to store them

[proven pine]

it's very common to save stuff

[brave cosmos]

Mine is a bit complex

[proven pine]

so there was pleanty of places i mentioned and others did as well

[subtle widget]

yy. my save system is too simple. cos then i've tried save items/skills/stats -> all die 😄

[proven pine]

it's up to you

but not the level blueprint lol

[brave cosmos]

For now I'll look into world subsystem and game state

[proven pine]

game state

would be the most fitting

[brave cosmos]

otherwise I'll store it in gamemode

[proven pine]

just literally "game state" the state of the game

[brave cosmos]

yes, let me look into them

Thanks for the insight!
