The multiplayer tank network game for the SpectraNet??
Yes!! Until UDP I will focus in the graphics engine. I have to port the full project from Z88dk to SDCC, from the Z88dk's SP1 tile and sprite lib maybe making a kind of wrapper to the cpctlera functions, and many more. I have to make a CPC.h to replace Spectrum.h, and the BSDsockets lib to make the fewer changes to the original game.

So there is not hurry for the UDP.
The tank server/engine is impresive. with few changes we can make some kind of CallOfDuty 2D deathmatch. With more straight maps and changing from rotational control to directional, the sprites for human soldiers, not tanks, reciclyng the fuel icon with grenades....
The client is just a loop that sends movement commands from keypress and draws sprites and sets the tilemap from UDP messages. Messages of create/destroy or relocation of the sprites, scoreboard, and the map tile section every time you change of map sector. Is just a player!!! all the IA is managed at the server...
And with a good hardware abstraction socket lib, if there is more hardware (ethernet, other wifis) the game just needs to change the lib and work with new hardware.
