View Full Version : idiot movement question
9th December 2002, 20:17
Just a quickie for anybody that likes answering stupid questions... how do I make something rotate in 2-D? I have a nifty effect that I'm using, and I want it to rotate clockwise, but for some reason (most likely my mathematical ineptitude) I can't figure out how to do it. :igor: Could somebody point me in the right direction...? Thanks.

In a movement, type:
Increase the 0.1 for a faster rotation. Or for more responsiveness, type this in a DM:
beat: bfr=rand(10)/100; a=-a;
In pixel, add d=d/1.05 for a bit of zoom.

If you need a list of effects rotating use a dynamic movement:
if you need a super scope rotating add t=t+0.05 to frame and this to end of poind section:

You can also rotate in the cartesian system.
It's faster that converting to polar then back (I think).

Quicker, but less acurate. The rectangular rotation is ellipsoidal, instead of circular.

You can scale the rotation the normal way.

Argh... this is not working out the way I wanted it to... this thing does not rotate well, apparently. Thanks for the help though, I'll keep it in mind next time I want to rotate something. :)

Post the preset. Let us see the code, maybe we can spot errors.
