jiagalypuff, I learnt its all about enabling and disabling (using switches) player and opponant per shot/move time from Wade_Adams while developing 'Borderline Conflict'. That started off as a turn based player (never finished it as I sufferred sever financial crisis and had to closedown my servers and stash everything for a year and a half but by then, my partner had dissapeared from the forums, old emails seemed not to work etc)
The idea was based loosly on Scorched Earth, one of the difinitive Turn based stratergy games from yonks ago that is now revived as a full 3D game.
There was also an underwater one that showed a good process too but have forgtten its name (so old).
