Hi, we're busy making an MMORPG (actually, improving an existing one and making a new client and server for it). In the current one, monster combat happens client side, and is very interactive, almost like a single player game: you have to walk to the monsters and hit the attack key on the keyboard for every attack. To make it much safer, we want everything to happen server side now, inclucing monster combat, so that players can't hack the client anymore and stuff. Now, the interactive combat system will be very unfair to players if there's lag, since the player has to send "attack" commands all the time and move around all the time to hit the monster, there should be no latency in that. Much lag friendlier is a point and click system where you click the monster once with the mouse and the server calculates all the rest of the combat, but then a very good aspect of the MMORPG is gone and replaced by "click and watch". Is there a way to have the interactive combat, but in such a way that it still works very well if there's lag and the server calculates everything?
