PP: 0.76 Compact World Update

[NotAFile]

The .76 world update is much more compact than the .75 world update.

It might be worthwhile backporting it to .75 OS under a new packet ID

[xtreme8000]

While it is more compact, there is one better solution:
uint8_t[] - bitmask array, every bit equals one player id
(the array has as many bytes/bits as required for all server slots)
then follow by as many float x,y,z,ox,oy,oz as there are connected players

My previous idea to this was to just send out all data for connected players, leaving out those ids that are disconnected, but this would result in problems when new players connect (world update is async, so a packet send before a playercreate packet could arrive after it and result in a 'data shift')

I'm not quite sure what you mean? If I understand it correctly, your format just saves one byte for the ID per player?

[xtreme8000]

yes, which is already a lot

[NotAFile]

True, at 10ups 32 players clients just save around 240B/s which is not really significant, but the server saves 8KB/s. This figure will only grow with 64 players and higher network ups so it would probably make sense.

I mean if we want to optimise bandwith, then do it at the most possible level. Especially considering protocol updates are hard to enforce on players.
