hello everybode,
im looking to program some simple screensavers in OSX, using openGL code, or just regular objective-C stuff. Can somebody tell me where i can start?
thanks

This probably isn't the ideal way to begin learning how to code screensavers under OS X, but it's a place to start. Go to epicware's OS X screensaver page and download the source code to some of the savers available.

There's also a note at the bottom of the page from the webmaster. You should take a look at it, as he hints how to get the private Apple headers necessary to make a screensaver work.

You may want to hold off until OS X final comes out -- the ScreenSaver headers will likely be publicized, and it wouldn't surprise me if the APIs have been cleaned up a little bit since Public Beta.

cool, i think ill wait

You can get the private headers, without doing a class dump yourself, if you download the source to OmniJulia. The headers are included. Take a look at OmniJulia too; it's pretty cool how they made it work.

Do you mind telling me where i can find the source for OmniJulia?
thanks

It is a program from the wonderful Omni Group.

You should download all of their programs.

lindberg is correct, in 4k78 the ScreenSaver framework is public and documented. It's changed slightly, but anything you do for the Public Beta should convert easily.

I have just updated my port of the xmatrix screensaver from PB to Final, and as 3.1416 suggested all changes were minor. For my code, it consisted of changing the header file from the reverse engineered one from PB to the Screensaver header and updating the method initWithFrame in my code. The new version of ScreenSaverView adds a new parameter to the method called isPreview, by which you can determine in your overriding method whether or not you are running in preview mode or full screen

I would be interested in your port of xmatrix. I am also interested in porting other screensavers from the xscreensaver package to OS X, but I don't know where to start. I've looked at the code for the EpicWare screensavers (a lot are from xscreensaver). It was easier for me to make changes to the existing ports than to make my own.

I would like to know if anyone knows where I can get documentation on the current ScreenSaverView.I checked the App kit and foundation release notes in the Cocoa topics.html file but could find nothing.Any info anyone has would be greatly appreciated.

The irritating part for a first-timer (This was my first screensaver) was separating the xscreensaver stuff from the actual xmtrix code. The task was not so much hard as it was tedious. Once that was done, I looked at the epicware SS source to figure out where to put everything. I'm still not entirely sure I made the best choices, but things seem to work fine, if a little bit slower than I would like.

Would you be willing to share your efforts?
