Need help :-|

Hello creative people.
I have created a particle trail ( with particular) that follows a null object . I’ve made the null object move in an eliptical fashion… sort of… using this expression:

r=thisComp.layer(“Null 1”).effect(“Radius”)(“Slider”) // radius;
u=time200 // angle;
x=rMath.cos(degreesToRadians(u));
y=(r/8)*Math.sin(degreesToRadians(u));
z=0;
c=[thisComp.width/2,thisComp.height/2,0];
add(c,[x,y,z])

The problem is that I dont know how to tilt it, using a degrees system or whtaever could be used in this case , something like this: http://www.youtube.com/watch?v=g8hvsiq5uWw . Any input would be more than apreciated.

Regards

PS: I’m using After Effects CS4

Simply parent it to a Null and reference the Null’s position as the center.

Thank you. I will try this and see where it goes, as you can see I’m a noob :slight_smile:
