after effects

Just make sure the position value of your last keyframe is equal to that of your first keyframe. Then apply the following expression:

loopOut(“cycle”)

[Mike Clasby]

If you have one revolution keyframed, and the first and last keyframes are the same you might try this loop expression:

loop_out(“cycle”,0)

But to get circular movement without keyframes, expression only, try this expression on position by Dan Ebberts (there are other expressions but I think this is the most controlable):

r = 50; //radius (in pixels)
f = 1; //orbits per second

angle = time*Math.PI*2*f;
value + [Math.sin(angle)*r, -Math.cos(angle)*r]

Just change the radius and orbit per second to taste.

[Steve Roberts]

… and you should set your work area to end 1 frame before the loop starts again.

For example, if frame 0 is the same as frame 50, the last frame of the work area should be 49.

hello steve,

my first step to a forum.
Thank you much.

I’ve got blind of checking and after reading your
message I could therefore finalley find my mistakes.
Two mistakes, forgot realley this time-management
and made instead curious things … (forget about)

Wish you a very good ending year with best with best

Hello Colin,

thank you very much!
Sorry, I’m answering late.
I did get yours and two other messages with tips and try this
all to become going on with my little own experiences.
All messages came from USA, never imagined something
and felt good that my english found this conversation, uff .

Some Time, I wish and hope to send you what I nice found
for creating my outlooks.
I felt glad about this resonance.
This was my first step within a forum!

So long with best wishes

Hello Yikesmikes,

I feel good that my english found this understanding and never
expect such’n resonance .
Specialley your keyframeless-expression was fine to try with.
Broughts a good mood and fun.

Some Time, I wish and hope to send you what I found out in
creating my outlooks.

This was my first step within a forum!

So long with best wishes
