Hi,
I would like to animate an NSImageView on the screen. Just a small
animation. So I don't want to use openGL because it's not easy and it
requires modern Video Boards.
I remember a sample at the WWDC 2001 which showed how to the speed-up
an
animation. There was a "train" of characters rotating along the
borders of
the window. I remember that animation was so fast, smooth and fine.
Even
faster at any new concept introduced by the speaker-man.
And I cannot get that nice result. The image flicks. Can you show me
the
finest way to animate my image? Thank you.
I did the following rude code:
------------------------------
In my NSView subclass I have a timer that each 0.005 NSTimeInterval
calls
200 frames / second ?!?!?
setFrameOrigin is calling another display method anyway.
