Random rotation on louvers

Hi !

I'm totally new on grasshopper and i can't find the solution to my problem. It might be simple but i spend hours on it without getting the good result.

Here is what i want to do:

Rectangulars louvers that each ones rotate along an axis while the wind blow on it.

I only succeed in rotating all my louvers but i don't know how can i select only the one i want to rotate (for example all louvers in a select circle are openend and the other one are closed).

I also have to do an array with that but i still don't know if i'm on the good way.

After that i would to do a "gradient angle of opening" (sorry for my bad english !): the ones on the centre of that selection are totally opened, the ones on the edge are halfway opened and the ones outside are closed.

Again sorry for my bad english and i just started grasshopper and watched video tutorials on that website.

Thanks

It's because of the "connecteurs".

If you copy these to your newly sized panels and reference them accordingly in the first step of the algorythm, the panels won't overlap... Basically, it uses the distance between these two to figure out the distance between the panels...

Thanks Nick it works well now ?

Another question, can the louvers follow a shape that is not a clear circle, like a closed curve for example, in order to simulate the wind trough those louvers ?

Not quite sure what you mean... Could you provide a quick sketch?

Sorry, i'm not really good to explain in english...

I attached my problem, actually the louvers follow a circle, and here i tried to set a curve to the "attraction curve" geometry and not the circle.

But as you see on the image, the movement of the louvers remain vertical instead of following the curve. Don't know if you see what i mean... I would like to simulate a gust of wind, that is not totally a perfect circle. The curve i draw is supposed to represent that gust of wind

Thanks for your answers
