Hi,

 

I have an Object A which contains a List of object B which each have a List of Object C.

So this is :

-A

--B1

----C1

----C2

----C3

--B2

----C4

----C5

etc..

 

I want to save it into my save.

So as Diesieben07 tell me, I search about how works WorldSavedData and MapStorage.

 

I have understand if you have only 1 field.

For example an Id, when it's changed, you call markDirty() and it will be save.

 

But in my case, if I make a WorldSavedData  for object A, when I want to save the modification of C2, if I mark A as dirty, all my sub-object will be saved right ?

 

How can I do to keep the same structure on my file with A is a NBTTagCompound, B a List, and C a List in B ? And in order that only C2 will be saved when I change it and not all the tree ?

 

I hope it's understandable

Okay

I didn't understand it like that

You have definitely solutions to solve all my issues

Thanks a lot Doctor Diesieben07
