Rotating wheels
OK.. I need to explain what I have first..
I have three circles, each one a little bigger than the other. I have put an expression on their rotation to a null. each with a divisional value so there speed is slightly staggered.
(e.g. comp(“Starter”).layer(“Null 1”).transform.rotation / 2.5)ok.. so here is my problem.. I have got the rotational speed I want.
0 to -420 over 750 frames..
However I now want to speed up and slow down the rotation but at stages still have the consistent speed from above..
I thought I might be able to add an additional null, and just parent the orginal one to it then just add rotation.. but that doesn’t really work..
so I am kinda stuck.. has anyone got any clever ideas ???
regards

I would think that instead of parenting the second null that you could just add it to the expression. Then while the second null is rotating, the circle turns faster, while the second null is still, the circle turns at the original rate, and while the second null turns in reverse, the circle slows down.
I haven’t tested it, but it should work.

Hi Dan,
Thanks for the reply..
Your Absolutly right.. I used this expression on my circles
z = 1.25
a=comp(“Starter”).layer(“Null 1”).transform.rotation / z;
b=comp(“Starter”).layer(“Null 3”).transform.rotation / z;
a+bAnd it worked a treat.. So I was kinda on the right lines..
thanks again
Alex
