orient layers towards ‘wall’
Hi,
I lhave 3 layers that are standing on a round platform linked to a null in the middle, so that when I rotate the null the 3 layers move correspondingly.
It’s like this: https://www.flickr.com/photos/10752691@N06/2646207377/sizes/o/now, when sliding over the floor, I want the layers to be oriented at the “wall” behind the camera
I tried this expression
LookAt = “ball”
look = look_at(position, this_comp.layer(LookAt).position);
[look[0], look[1], look[2]]but it does not seem to work..
Anyone a clue?
regads,
Jochem

Do you need the auto orientation to occur on an axis other than the layer’s y axis, and/or do you need it to orient to a direction other than to the front? If not, it might be as simple as applying this to each layer’s y rotation:
v = toWorldVec([0,0,1]);
-radiansToDegrees(Math.atan2(v[0],v[2]))Dan

Hi Dan,
it’s double ‘no’, and your expression does the trick
great, thanks, I can move on..Johan
