I finally got fullscreen mode working properly in my game!

There's a one problem left though...

When in fullscreen mode, the display doesn't want to go to sleep. Is there some way around this? I'd like the display to keep obeying the user's Energy Saver settings. Is there an easy way to do this?

I've been looking at DMRegisterExtendedNotifyProc and kDMNotifyDisplayWillSleep... am I on the right track?

BTW, this is a Cocoa app.


Thanks in advance,

Andrew


PS - many thanks to OneSadCookie for his ridiculously abundant, very helpful posts! I can count the number of times I've run into some coding issue, hit up Google, and found a useful OSC post on iDevGames. Thanks Keith!

I don't have a solution for you, but I can tell you that at least personally I get very annoyed whenever a fullscreen application lets the display go to sleep... it makes watching a movie/video much less fun! Especially when you have to type in your password to unlock the screensaver...

I'm calling UpdateSystemActivity(UsrActivity); when the user is providing input, so the display won't sleep when the user is playing the game. However, if the user walks away from the game, their display should sleep after the period they specified in Energy Saver. I'd also like to adhere to their Screen Saver settings if possible.

I could simply draw a black screen after a set period, but I'd prefer to relinquish control to the system (and obey the user's system preferences) if that's possible.

I forgot to mention that I'm achieving full screen mode via a second OpenGL context.

That is, I'm not doing something like this:
[fullScreenWindow setLevel:NSScreenSaverWindowLevel-1];
