Hi i have the problems abount WorldSavedData i know want use DimensionSavedDataManager but i don't know how to use please Example.

I normally use MapStorage with getPerWorldStorage () to call NBT or Data.

 

public static WorldData forWorld(ServerWorld world){
        
        World a = (World)world;
        
        DimensionSavedDataManager storage = world.getSavedData();
        
        storage.set(new WorldData(key));
        
        //MapStorage storage = world.getPerWorldStorage();
        
        //WorldData result = (WorldData)storage.getOrLoadData(WorldData.class, key);
        
        /*
        if (result == null) {
            result = new WorldData(key);
            storage.setData(key, result);
        }*/
        
        return result;
    }
    
    WorldSavedData get(String nbame) {return this;}

 

Hello diesieben07 How are you ?

I can't find in vanilla but i think this can work thank you.
 

public WorldData() {
        super(key);
 }

storage.getOrCreate(WorldData::new, key);
