mcpe 0.16 support 'varint'

[ghost]

<gurun> talked to mojang today. The NBT for items, chunks and other stuff is a mess right now, even for them. They ARE moving towards all of it going over the wire to be VarInt style, but right now .. it's totally a mix. ​

I present you, the new specification!
varint is always little-endian (finally they can settle on something)
we also need varlong, I don't think ProtoDef has that

Here is an implementation in C# NiclasOlofsson/fNbt@61619ac
Strings are varint prefixed, and there can be varint32 and varint64 fields it looks like

• All ints are now replaced with varints
• We will need to actually separate the implementations

feel free to start writing a .json for this.
Once it can decode mcpe nbt properly, we'll see how to integrate it properly here. (Would be useful to have some mcpe nbt example files !)

Ah yeah, I'll ask around and see if I can grab a 0.16 NBT file, or if I can generate one myself

[rom1504]

would be useful to put infos here

• link to nbt example
• description of the new format
