I would like to have an update to show but in placing the trees I found a bug in Lightfeather. The dev is looking into it... Meanwhile Robbie Williams has been keeping me busy lately...
I've been doing some practical thought experiments and have created a basic server and client interface. So far they both load maps and set up the respective connections (using RakNet).
At the moment the client can tell the server when tiles are loaded and unloaded. A "tile" is defined as blocks of 64x64 heixels (height pixels) on a universal board of 16x16 of these tiles (to make 1024x1024 heixels in total).
This information can thus be used to "register" an interest in a tile and thus the server will then (later) be able to tell the client when something interesting happens on any of these tiles the client has registered.
