 Getting even spacing of 7 circles around a center glob, all using copies of the same motion path, how to? on May 14, 2017 at 1:56:45 pm

HI all, I have this going on:

And I want to get the 7 globes evenly spaced around the motion path.

As you can see, I am using the offset for each copy of the motion path to nudge the starting point of each circle. There must be some math involved, only I can't figure it out.

Thx Mark, tried that at first, and 1) the problem is still the same (precise placement of 7 objects around a 360 degree circle), and 2) the orbit behavior is not as nice as the motion path one ☺

[Jiggy Gaton] "As you can see, I am using the offset for each copy of the motion path to nudge the starting point of each circle. There must be some math involved, only I can't figure it out"

It looks like the Motion Path behavior's Offset parameter represents % of full orbit around the circle (360 degrees). If you have some objects to distribute evenly I think you'd just divide 100 by the number of objects (in this case 7) and space the offset values that far apart - so 100/7 = about 14.3 (or say 14.286)
so
object 1 = Offset zero
object 2 = Offset 14.3
object 3 = Offset 28.6
object 4 = Offset 42.9
etc.

I tried to post a motion project here

Thx so much for that Dirk!!! Perfect. I used to be good at math, but then I went to Woodstock, and ever since I've been crap at it ☺

Wouldn't a simple circular, animated Replicator be perfect for this?

Ha! Well, in theory yes, but the other project that I am working on using Replicator in Motion 5 (

) is stuck - can't spin an object with associated text. So I was not thrilled to divide up the circle that way...at least not until I can figure out that problem (or is it a bug?). Thx!!!

I was thinking that too, but if the 7 objects aren't the same then maybe not... but a replicator may be able to be used somehow anyway...

...but I'm happy with what I got. I just wish I could get replicator to handle text on a path correctly...

You simply make a movie (or image sequence) of the images and tell the replicator to use a different frame of said movie (or sequence) for each point.

[Robin S. Kurz] "You simply make a movie (or image sequence) of the images and tell the replicator to use a different frame of said movie (or sequence) for each point."

That sounds like a good idea.

In other particle generating software I've used (mostly AE plugins) I've often seen that it can be slow using an animated particle image and offsetting the animation between particles in any way... but hopefully if it was set to use only a single frame the offset wouldn't cause a significant performance hit - but it's not something I've looked closely at in Motion yet (I will in the future) - it depends on whether it's "smart" enough to take advantage of the potential optimization in that situation
