Searching a way to "rotate" position with a angle controller
Hi ! 👋
I am currently working on a animation, and I looking for an expression to link my position to an angle controller.
By editing the angle controller I want the position to “track the angle”, as You can see on the image, with the black text equal to the angle of the controller :
I tried some code à found here, but none of them worked :/
I don’t know if it is possible, but i could save me hours of work !
Clément.

The image wasn’t included…
do you mean something based on trigonometry ?
Like:
a=degreesToRadians(45);
pos = [Math.cos(a),Math.sin(b)]*100;

Hi Filip,
Yes the image is missing…
<div>I think it is the kind of code I am looking for, maybe the image will help you.</div>

Yes, this can be done with cos and sin, just subtract 90°, in Maths 0 degrees means the 3 o clock position.

Thanks Filip ! After few tweaks I found this code and it worked fine !
b = thisComp.layer("Null 1").effect("Angle Control")("Angle");
a=degreesToRadians(b);
pos = [Math.cos(a) , Math.sin(a)];
