1.8 - Remove a world saved data

[Blackout]

Hello

 

I want to remove a custom WorldSavedData, how can I do this ?

 

In my mod, I need to store things for each explosion. Each explosion will have an WorldSavedData object.

I will replace all block by the explosion, when no more block left, I want to remove the WorldSavedData entry.

 

I don't want to just remove it from Map, I want to remove it from file.

I think you might be missunderstanding what WorldSavedData is. Its kinda of like IExtendedEntityProperties.

 

Create ONE WorldSavedData per world that is corresponding to your mod. In that WSD hold a MAP or ARRAY of custom objects that store your "explosions".

Use whatever you like to remove those "explosions" from map/array.

 

In WSD#write/readNBT use NBTTagList and create NBT-list with your custom "explosion" objects.

The problem is that I don't want to load all data in RAM.

If I have one WorldSavedData wich contains all my explosion data in a Collection, all will be loaded.

How can I solve this problem using the minecraft save system ?

 

I wanted to use ChunkDataEvent to store explosionID wich is my WorldSavedData key.

That data will be loaded no matter if you have one or several WSD - that's what it is for. (Edit: I feel retarded, for forgetting that).

 

If you want to load-on-demand you need to write your own saving system.

Pretty simple. Make your directory with explosions and save them per-date or something using CompressedStreamTools.

WorldSavedData is not loaded by default. You should explicitly use MapStorage.loadData().

 

I will try using my own system, using CompressedSteamTools. Thanks

But I still accept alternate solutions
