Frage von zulukatan:


Hello,

So maybe yes, I looked after just the wrong word but I find no answer to the following question.

First, what I intend:

Layer 1: rotates once in the y axis to itself 360 ° (anchor point ligt aussehalb; therefore revolves around an object)
Layer 2: should the same thing, just s.einem other starting point and with a different speed and a different anchor point depth.
Layer 3: Exactly the same as layer 2, ETC.

The whole is more than 20 levels!

I thought to myself now that the CIH that with a random number "random ()" can be solved, but how you use it? he is my only s.anfang A number, but the Random function returns yes Keeps different, so everything goes out and her?

How do I do with the speed of rotation and the initial angle?

I have presented the I Refferenzwinkel as a variable to create. So, "R1". To each layer is doubled.

Layer 1: 360 ° rotation s.0 ° (Variable "R1 = [10]" for example)
Layer 2: 360 ° rotation s.R1
Layer 2: 360 ° rotation s.R1 + R1

But how can I get the value of R1 in the second layer, etc.?!
Automatic for the entire Comp seems it does not define. But how do I change this value? geht das überhaupt?

The first are the most important questions!
If someone is a very different solution approach, I am happy s.anderen solutions synonymous interested!

Thank you!

All complete nonsense, just look at the brain to store trash and the mind free.

random () for each layer fixed angle:


seedRandom (index, true)


reference the previous layer:

thisComp.layer (index-1)

Everything else is Kinderkram. Random () can return any value (simple range, array, multiple ranges) and thus can tinker with everything what you need.
