Is it possible to get chunks from the server out of the view distance from the client? And render them. I whoud like to make some kind of camera, but on a server you will get quickly to the chunk borders.

 

And how do I do that, I mean the client is deleting unused chunks, where is he doing that (can I somehow foce him not doing that) And is it possible to send the chunk data from the server to the client via vanilla packages, will that work?

First of all, the client does not unload chunks. If the server does not tell the client to unload some chunk, the client will keep that chunk forever.

So all you really have to do is "just" re-implement all the chunk-tracking for the chunks you want known on the client in addition to the ones already there.

 

Does that mean if I stop the server to send unload packages the client will keep ALL chunks?

 

Well I think the chunk traking will be on the client side, if there are tomany empty chunks, then I will send a custom package to the server, I hope this will not get to difficult.

Indeed. If the server does not send the unload packet, the client keep the chunk in memory. It will not keep it rendered if it's outside viewing distance, but it will stay loaded.

 

This is particularly amusing with the vanilla boat desync bug.

 

I once was traveling so far by boat that the client-player (me) ended up in an unloaded chunk (client side, obviously).  I could see the chunks that were loaded in front of me, but I was not in them.

I had to logout/login at that point, as the client was unable to keep traveling farther.  It was busy trying to fall.
