Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
You could mke something like shrooms idea... the platforms would stay level with the correct coding.. (The balloon in lakeside goes round and also up and down.. but always stays upright regardless... Its a similarish principle.. everything works on rotation.. even the lift in DC that just goes up and down)
But... TP is right about the moving objects on moving objects.... still worth a go though.. anyone ever driven a car on the aircraft carrier in bf42? i dunno what its like.. (with the ship moving).
The main issue is making sure everyone sees the 'object' in the same position on each screen.. it must have network info.. which could potentially cause lag.... back to the balloons in lakeside... you may not be aware but they 'start their journey' round from the same spot when 'your' game has loaded... so they may well be in a totally different position on someone elses screen.. or on the server... thats why the collision on them is weird.. and does not really work.
