Steve and I have talked about this a bit and we've concluded that the
risk (being Open Source) of being very easily hacked is too great for us
to trust the clients about anything. We have two choices: (1) who cares
about security, let's just be friends, or (2) watch everything the
player does.
(1) would be easy and we could be done really fast, but people will hate
us for it down the road if we go that way.
For (2), the server must simulate everything during battles. That
include projectiles, sword swings, character movement, and everything.
As Steve mentioned, if things are off by even a little, and it's
someone else's fault, people will freak out. So we have to make sure
that if someone gets screwed by lag, it's you getting screwed by your
own lag.
The character stats, inventory and money all need to be stored at the
server. Any transactions that player may perform must go through the
server. In this way, the server is like a database server, and no data
is stored locally on the client. That said, a temporary copy of the
character data is stored on the client, but if this doesn't match the
server, the server data always takes precedence.
The client will simulate non-essential physics such as movement of the
player character and objects the character sets in motion. For
instance, if the PC kicks a rock, the rock will move and be simulated on
the client. However, the server will check the position updates
periodically to make sure nothing funny happens (such as a teleport).
Any thoughts? Other than "Oh, that requires too much server processing
time." Obviously that's a concern, but let's just talk about how it
should work first, then worry about the implementation.
