[1.20.4] tutorial guide working example for creating Level capability ??

[perromercenary00]

 

im stuck in a problem whit BlockEntities i cannot solve
so im trying to work around it but in the less complex way possible 

i think is posible to store data to the minecraft world 

in older versions people talk about  WordDataSave i dont find anything about it for 1.20.4 

i find a tutorial for player capability in 1.19

here is an event 

	
    //########## ########## ########## ##########
    @SubscribeEvent
    public static void onAttachCapabilitiesPlayer(AttachCapabilitiesEvent<Entity> event) {
        if(event.getObject() instanceof Player) {
            if(!event.getObject().getCapability(PlayerThirstProvider.PLAYER_THIRST).isPresent()) {
                event.addCapability(new ResourceLocation(mercmod.MOD_ID, "properties"), new PlayerThirstProvider());
            }
        }
    }
	

 soo i made this 

    //########## ########## ########## ##########
    @SubscribeEvent
    public static void onAttachCapabilitiesLevel(AttachCapabilitiesEvent<Level> event) {

    }

i think i can do some witchcraft  here  but is many things don't understand 
to start whit i dont get yet how to recall the saved data from a BlockEntity 

the handler still in progress the plan is to make a Map to store nbt data using the block coordinates as index

later store that map as a big nbt

any way the question is if theres alredy a tutorial for 1.20.4 for this ??

or some alredy working code from someone else doing something similar ?
