However, obfuscation or cloaking is not. It might be worth while to cloak your data just a little. This helps to prevent spoiling the game to gamers that out of curiosity, or accidentally view the data. And it can also help to lessen the temptation of cheating. Obsuscation of the data should be a bit like a warning: "Better not mess with this, unless you sure you want to". Sop, I woudln't worry too much about being able to see your password string of the data file in the executable. The data is cloaked, and protected from casual curiosity. That should be enough for a game. -- "No one knows true heroes, for they speak not of their greatness." -- Daniel Remar.

X-UIDL: 325116450 Status: O Content-Length: 332 Lines: 10 i blit an AL_BITMAP to the windows desktop using blit_to_hdc() but it seems very slow compared to blitting to a DC that belongs to another window. is this because the blit_to_hdc() also forces the destination DC to redraw itsself completely? if so, is there a way to make the destination DC only update the dirty rect ? aj. |
