How do objects like "PathNavigate" and many others persist across saves?

Posted October 11, 20186 yr

I'd like to understand more about how minecraft saves data. I know there is NBT reads and writes but I don't think that is used for everything is it? Let me use an example for my question. On EntityLiving is this member:

protected PathNavigate navigator;

It holds a variable that I know persists across saves and reloads of the game:

protected Path currentPath;

So how is this data saved? I don't see any NBT read/write code for it. Does it do something like serialize and write the whole Entity object out to file?

Any help to understand this would be great.

It is used to save everything, what logical thought process would lead a developer to create two different types of saving methods for one game?

How do you know said variable persists?

Unless there is a writeNBT() type method in the class, or some other class that grabs data from the class, then it probably isn't actually saved.

So yes I agree, it must only be NBT reds/writes that get things saved. Turns out that path var and many other things actually get re-initialized from scratch when a world is loaded.

So if I want to save my own data to the a save, I guess I use what is explained here:

Capabilities just wrap around World Saved Data. However it may need to be an entity capability if it is something like the provided example.
